Autonomic nervous system evaluation in allergic rhinitis.

OBJECTIVES: To evaluate the relationship between allergic rhinitis (AR) and autonomic nervous system (ANS) dysfunction. METHODS: Quantitative ANS testing was completed in 10 patients with AR confirmed by clinical findings and allergy testing. This data was compared to 16 age-matched controls. RESULTS: ANS scores were significantly abnormal in AR patients when compared to normal controls. The composite autonomic scale score for the AR group was significantly impaired when compared to controls (1.6 vs 0.63, P < 0.0001). Additionally, subscore values quantifying the level of dysfunction within the sympathetic nervous system (1.0 for sudomotor and 0.5 adrenergic) were found to be significantly different (P < 0.0001 and 0.018). The mean subscore value quantifying the level of dysfunction within the parasympathetic system (cardiovagal) was not found to be significantly different from controls (P = 0.38). CONCLUSIONS: ANS dysfunction, specifically sympathetic hypofunction, was identified in all of the allergic rhinitis patients studied. Further characterization of the type of ANS abnormality may allow the development of novel pharmacologic therapies for these disorders.

Adult chronic rhinosinusitis: surgical outcomes and the role of endoscopic sinus surgery.

PURPOSE OF REVIEW: To review the recent literature as to the role of and data supporting endoscopic sinus surgery for the treatment of adult chronic rhinosinusitis. RECENT FINDINGS: Many studies have been published evaluating patient responses to endoscopic sinus surgery. These responses have included subjective measures such as patient-reported symptoms, and subjective symptoms measured objectively, as seen with quality-of-life instruments. Others have used objective measures such as endoscopy scores, medication use and financial impact to measure responses to surgery. These studies have varying follow-up, with patients followed for up to several years postsurgery. The results are very consistent, with most studies reporting improvement in both subjective and objective findings postoperatively. SUMMARY: The data in the literature clearly support the use of functional endoscopic sinus surgery in cases of chronic rhinosinusitis refractory to medical therapy. Surgery has been shown to improve patient symptoms, quality of life and intranasal endoscopic exam.

Patients undergoing sinus surgery: constructing a demographic profile.

OBJECTIVES: The objective of this study is to construct an accurate and representative demographic profile of patients undergoing sinus surgery for chronic rhinosinusitis (CRS). This will enable future studies to enroll representative samples so that results can be more easily compared across studies and generalized to the U.S. population. METHODS: The investigators interrogated the databases of the National Survey of Ambulatory Surgery to gather demographic data. Whenever the NSAS provided incomplete characterization, deficiencies were corrected using state-level data provided by the Health care Cost and Utilization Project. The constructed profile was compared with available profiles of patients with CRS and demographic data provided by the U.S. Census Bureau. RESULTS: The demographic profile of patients undergoing sinus surgery is 52.7% female with a mean age of 38.5 years. A total of 93.5% of surgery is performed on an outpatient basis with 78.8% of patients having private insurance sources. No significant difference in occurrence of surgery was found between months of the year or between regions of the country. The constructed race profile is 85.7% white, 5% black, 1.2% Asian/Pacific Islander, 0.2% Native American, and 7.8% other. CONCLUSIONS: A novel integration of national and state databases can be used to create a demographic profile of patients undergoing surgery for CRS. The creation of this profile enables further study of representative populations of patients with CRS and enables thoughtful analysis of the existing literature. The difficulty in creating the profile highlights the need for complete and accurate healthcare information collection by national and state agencies.

Sex differences in outcomes of sinus surgery.

PURPOSE: Sex has been demonstrated to affect outcome in many diseases. Our current aim is to investigate the relationship between sex and outcomes of endoscopic sinus surgery (ESS) in patients with chronic rhinosinusitis (CRS). METHODS: Forty-four males and 73 females undergoing ESS for CRS with a mean follow-up of 1.4 years were evaluated prospectively. Computed tomography (CT), endoscopy, and quality of life (QOL) assessment was performed. Univariate analyses were performed to evaluate whether sex was predictive of outcome. Multiple logistic regression analysis was performed to evaluate sex association with patient factors predictive of outcome. RESULTS: Although no sex differences in CT and endoscopy were observed (CT, P=.107 and endoscopy, P>.1), females consistently scored worse than males on disease-specific QOL pre- and postoperatively. Importantly, there was no effect of sex on improvement/change scores for the QOL instruments. PREDICTIVE MODELS AND MULTIPLE LOGISTIC REGRESSION ANALYSIS: Sex was not found to be predictive of QOL or endoscopic outcome. Female sex was, however, associated with acetylsalicylic acid (ASA) intolerance and depression, both factors that have been associated with poorer outcome. CONCLUSION: Despite similarities in objective disease measures, females report significantly worse QOL scores pre- and postoperatively. Postoperative improvement did not differ by sex, nor was sex predictive of postoperative outcome. Sex differences in QOL reflect sex differences in ASA intolerance and depression, both more prevalent in females.

Diagnostic testing for vocal fold paralysis: survey of practice and evidence-based medicine review.

OBJECTIVES/HYPOTHESIS: Vocal fold paralysis continues to be a dominant topic in laryngology. Although the majority of cases can be attributed to a known etiology, a significant number of patients present without a clear precipitating event. Over 1,500 studies regarding vocal fold paralysis exist in the medical literature, although only a small percentage report on the use of serum or radiographic testing for the evaluation of idiopathic paralysis. Despite this, patients are routinely subjected to diagnostic evaluation to investigate the underlying cause. To characterize contemporary practice, a national survey of the American Broncho-Esophagological Association (ABEA) membership was undertaken. It is hypothesized that the current practice of diagnostic testing for idiopathic vocal fold paralysis is not well supported by an evidence-based medicine (EBM) review of the available medical literature. STUDY DESIGN: The authors conducted a national survey, systematic EBM review of existing literature. METHODS: Surveys were mailed to all active ABEA members; responses regarding practice specialization as well as serum/radiographic diagnostic preferences for idiopathic vocal fold paralysis were tabulated and subjected to statistical analysis. To compare contemporary practice with evidence in the available literature, an EBM review was first performed. Articles for evaluation were selected from a Medline search of English-language abstracts related to adult vocal fold paralysis. The publications were individually reviewed and an EBM level and grade were assigned and compared with the survey results. RESULTS: Eighty-four of 249 active members responded with 76 (31%) replies submitted for analysis. Specific serum tests were advocated by 41 of 76 (54%) respondents, although the majority (52 of 65 [80%]) felt that they were only "occasionally" or "never" necessary. The most common tests were rheumatoid factor (38%), Lyme titer (36%), erythrocyte sedimentation rate (34%), and antinuclear antibody (33%). Fifty-one of 71(72%) felt that computed tomography (CT) was "always" or "often" necessary and 50 of 72 (69%) replied that chest radiography (CXR) was "always" or "often" necessary. There was no significant difference between CT and CXR ordering (P < .51). In contrast, magnetic resonance imaging (MRI) was described as "always" or "often" necessary in 28 of 71 (39%) of the surveys, significantly less than CT (P < .0001). There was no statistical impact of practice specialization on ordering of serum tests (P = .25) or imaging (P = .50 for CT; P = .46 for CXR; P = .45 for MRI). Following analysis of 1,510 vocal fold paralysis abstracts, 19 publications were found to be appropriate for an EBM review of serum testing with 15 available for review of radiographic imaging. Only one study presented level III evidence; the remainder were levels IV and V comprised of retrospective series and case reports. The evidence supporting serum or radiographic testing toward the evaluation of idiopathic vocal fold paralysis is given an overall grade of "C." CONCLUSIONS: Serum and radiographic testing for the evaluation of vocal fold paralysis is supported by grade "C" evidence only. There are no existing prospective studies estimating the clinical impact of testing on diagnosis or patient outcome. Current practice, as estimated by a survey of the ABEA membership, is not well founded for serum testing and only by retrospective case series with regard to imaging. Further study into the nature of idiopathic vocal fold paralysis and outcomes assessment of diagnostic paradigms may improve clinical practice.

Comparative in vitro antimicrobial activity of a novel quinolone, garenoxacin, against aerobic and anaerobic microbial isolates recovered from general, vascular, cardiothoracic and otolaryngologic surgical patients.

OBJECTIVES: The aim of the study was to analyse the susceptibility of unique and non-duplicate aerobic and anaerobic isolates from surgical patients to a novel des-F(6)-quinolone (garenoxacin) and other selected antimicrobial agents. METHODS: Eleven hundred and eighty-five aerobic and anaerobic isolates from general, vascular, cardiothoracic and otolaryngologic surgical patients were tested for susceptibility to garenoxacin and seven other antibiotics (ciprofloxacin, moxifloxacin, levofloxacin, piperacillin/tazobactam, imipenem, clindamycin and metronidazole) using the referenced microbroth and agar-dilution method. RESULTS: Garenoxacin exhibited greater antimicrobial activity than comparator quinolones such as ciprofloxacin, levofloxacin and other antimicrobials when tested against selected gram-positive organisms. The in vitro aerobic and anaerobic activity of garenoxacin was similar to that of moxifloxacin. All fluoroquinolones tested were effective against most gram-negative facultative anaerobes including Escherichia coli. Garenoxacin and moxifloxacin demonstrated similar in vitro antimicrobial activity against selected anaerobic gram-positive and gram-negative anaerobic bacteria such as members of the Bacteroides fragilis group. Overall, the in vitro activity of the advanced spectrum quinolones against anaerobic surgical isolates compared favourably with selected comparator agents, metronidazole, imipenem and piperacillin/tazobactam. CONCLUSIONS: These findings suggest that 82.4% of aerobic surgical isolates were susceptible to a concentration of garenoxacin < or = 1.0 mg/L, whereas 84.5% of the anaerobic isolates were susceptible to a garenoxacin concentration < or = 1.0 mg/L. Garenoxacin may be a valuable surgical anti-infective for treatment of serious head and neck, soft tissue, intra-abdominal and diabetic foot infections.

Nasal valve surgery improves disease-specific quality of life.

OBJECTIVES/HYPOTHESIS: Disease-specific quality-of-life (QOL) assessment of patients with nasal valve compromise and symptomatic nasal obstruction has not been studied previously. The objectives of the study were to determine whether surgical treatment of the nasal valve improves disease-specific QOL and to identify clinical or demographic variables predictive of patients' baseline QOL or change in QOL. STUDY DESIGN: Prospective, multi-institutional outcomes study of 20 patients with nasal obstruction and a surgically treatable diagnosis of nasal valve compromise. METHODS: Disease-specific QOL assessment was performed using the Nasal Obstruction Symptom Evaluation (NOSE) scale preoperatively (n = 20) and at 3 (n = 14) and 6 months (n = 20) after surgery. Clinical and demographic data were collected, along with physician-reported assessments of degree of nasal obstruction. RESULTS: Mean NOSE scores significantly improved from baseline to 3 months after surgery (68.9 vs. 20.7 [P < .0001]), from baseline to 6 months after surgery (68.9 vs. 15.8 [P < .0001]), and from 3 to 6 months after surgery (20.7 vs. 15.8 [P = .0077]). Physician assessment of degree of nasal obstruction using a visual analogue scale was significantly correlated with baseline NOSE scores (P = .013) and change in NOSE scores at 6 months (P = .0015). No other clinical or demographic factors were found to be predictive. CONCLUSION: In patients with symptomatic nasal obstruction and nasal valve compromise, surgical repair of the nasal valve improves disease-specific QOL. Physician rating of degree of nasal obstruction was found to be significantly correlated with patient-reported QOL.

Predictive factors and outcomes in endoscopic sinus surgery for chronic rhinosinusitis.

PURPOSE: To assess objective and quality of life (QOL) outcomes before and after endoscopic sinus surgery (ESS) in patients with chronic rhinosinusitis (CRS) and to determine preoperative factors that predict surgical outcome in these patients. METHODS: One hundred nineteen adult patients with CRS and a mean follow-up of 1.4 +/- 0.35 years were evaluated prospectively including the following patient factors: prior sinus surgery, polyps, asthma, acetylsalicylic acid intolerance (ASA), smoking, allergy, depression, and sex. Computed tomography (CT), endoscopy, and QOL assessment was performed. Predictive value of patient factors was determined based on change in endoscopy and QOL scores after ESS. RESULTS: Objective outcomes: preoperative CT scores were significantly worse in patients with polyps, asthma, and ASA, whereas CT score was unaffected by prior sinus surgery, smoking, allergy, depression, and sex. Patients with CRS demonstrated significant improvement on nasal endoscopy after ESS, but preoperative, postoperative, and change in scores were affected by certain patient factors. Endoscopy scores were significantly worse in patients with prior sinus surgery, polyps, asthma, and ASA, but these patients also experienced the greatest improvement in endoscopy scores. Smokers and patients with depression had the least change in endoscopy scores. QOL outcomes: patients with CRS experienced improvement in QOL after ESS. Pre- and postoperative QOL was positively affected by polyps and adversely affected by ASA, depression, and female sex, but these groups still experienced significant improvement in QOL scores. Pre- and postoperative QOL was unaffected by prior sinus surgery, asthma, smoking, and allergies, and all of these groups experienced significant improvement in QOL scores. Factors predictive of outcome: ASA and depression were predictive of worse outcome. Preoperative CT scores approached significance as being predictive of outcome. CONCLUSION: Surgical management of CRS was associated with significant improvement on objective and QOL measures; however, specific patient factors, in particular ASA and depression, predict poorer outcome. Preoperative CT may be a predictor of endoscopic and QOL outcome and deserves further study.

Laryngeal electromyography for adult unilateral vocal fold immobility: a survey of the American Broncho-Esophagological Association.

OBJECTIVES: Diagnostic and management strategies for adult unilateral vocal fold immobility (UVFI) vary among otolaryngologists. The aim of this study was to determine the current attitudes and practices regarding laryngeal electromyography (LEMG) for the management of adult UVFI within a cohort of subspecialty laryngologists. METHODS: A 19-item instrument focused on diagnosis and management of adult UVFI was mailed to active members (n = 249) of the American Broncho-Esophagological Association (ABEA). The subset of questions related to LEMG is reviewed in this report. Statistical analysis using a chi2 test was performed. RESULTS: The survey response rate was 34% (n = 84), with 8 surveys returned incomplete because of pediatric-limited practices. Of the respondents, 75% (n = 57) rely on LEMG for evaluation of UVFI, whereas 25% (n = 19) do not use LEMG. Of those who use LEMG, 54% place their own electrodes and 44% interpret the LEMG results themselves. Monopolar electrodes are used by 57% (n = 25), bipolar electrodes by 27% (n = 12), and hooked-wire electrodes by 17% (n = 7). Muscles evaluated by LEMG include the thyroarytenoid (100%), cricothyroid (94%), posterior cricoarytenoid (70%), lateral cricoarytenoid (43%), cricopharyngeus (27%), and interarytenoid (17%). The LEMG is performed in an unblinded fashion by most respondents (85%), and many (66%) feel a more accurate result is obtained when clinical information is known. There was no statistically significant difference in use of LEMG, placement of electrodes, and interpretation of LEMG according to percentage of laryngology practice. CONCLUSIONS: The survey results demonstrate congruence among ABEA members in the utility of LEMG in the management of adult UVFI. Some variability was noted in the methods by which LEMG is performed and interpreted.

Quality of life and sun-protective behavior in patients with skin cancer.

OBJECTIVES: To determine whether change occurred in the general quality of life (QOL) of nonmelanoma skin cancer (NMSC) patients following surgery, to identify variables associated with patients' change in QOL, and to assess the impact of the disease and treatment on sun-protective behaviors and cigarette smoking. DESIGN: Longitudinal prospective study of 121 consecutive patients referred to a dermatologic Mohs surgery clinic with NMSC of the head and neck. INTERVENTIONS: Quality-of-life, smoking habit, and sun-protective behavior assessments were performed before treatment (N=121) and after surgical treatment at 1 (n=105) and 4 (n=101) months. Quality-of-life measures included the Medical Outcomes Study 36-Item Short-Form Health Survey and the Functional Assessment of Cancer Therapy-General. RESULTS: Overall, general QOL measures demonstrated little change over time. Only the mental (Medical Outcomes Study 36-Item Short-Form Health Survey) and emotional (Functional Assessment of Cancer Therapy-General) domains of QOL showed statistically significant change over time. A 2-way interaction showing effects for age and time on emotional well-being was modified by a 3-way interaction that depended on employment status. Emotional well-being scores for younger employed NMSC patients increased over time compared with scores among younger unemployed patients. In addition, many patients adopted greater use of sun-protective behaviors at 4 months following surgery. No change in cigarette smoking status was evidenced. CONCLUSIONS: Use of sun-protective behaviors increases after treatment. General QOL instruments demonstrate little change following treatment of NMSC. Although the associations are modest, improvements in emotional and mental health well-being following treatment of NMSC were demonstrated, especially for those younger than 65 years and employed. A disease-specific instrument may be necessary to further study this disease process.

Development and validation of the Nasal Obstruction Symptom Evaluation (NOSE) scale.

OBJECTIVE: The study goal was to validate a disease-specific health status instrument for use in patients with nasal obstruction.Design, settings, and patients The study consisted of a prospective instrument validation conducted at 4 academic medical centers with 32 adults with nasal septal deformity. METHODS: Prospective instrument validation occurred in 2 stages. Stage 1 was the development of a preliminary (alpha-version) instrument of potential items. Stage 2 was a test of the alpha-version for item performance, internal consistency, and test-retest reliability; construct, discriminant, criterion validity, and responsiveness; and creation of the final instrument. RESULTS: Items with poor performance were eliminated from the alpha-version instrument. In testing the final instrument, test-retest reliability was adequate at 0.702; internal consistency reliability was also adequate at 0.785. Validity was confirmed using correlation and comparison analysis, and response sensitivity was excellent. CONCLUSIONS: The Nasal Obstruction Symptom Evaluation Scale is a valid, reliable, and responsive instrument that is brief and easy to complete and has potential use for outcomes studies in adults with nasal obstruction.

Outcomes after nasal septoplasty: results from the Nasal Obstruction Septoplasty Effectiveness (NOSE) study.

OBJECTIVE: Our goal was to assess disease-specific quality of life outcomes after nasal septoplasty in adults with nasal obstruction. DESIGN, SETTINGS, AND PATIENTS: We conducted a prospective observational outcomes multicenter study with 14 sites and 16 investigators, including private practice and academic settings. Patients had had septal deviation and symptomatic nasal obstruction for at least 3 months, and medical management had failed. METHODS: Patients with septal deviation completed a validated outcomes instrument (the Nasal Obstruction Septoplasty Effectiveness [NOSE] scale) before and 3 and 6 months after septoplasty, with or without partial turbinectomy. RESULTS: Fifty-nine patients underwent surgery; there was a significant improvement in mean NOSE score at 3 months after septoplasty (67.5 versus 23.1, P < 0.0001), and this improvement was unchanged at 6 months. Patient satisfaction was very high, and patients used significantly fewer nasal medications. CONCLUSIONS: In patients with septal deformity, nasal septoplasty results in significant improvement in disease-specific quality of life, high patient satisfaction, and decreased medication use.

Management of cerebrospinal fluid rhinorrhea: the Medical College of Wisconsin experience.

INTRODUCTION: The management of cerebrospinal fluid (CSF) rhinorrhea has evolved in recent years. The purpose of this comprehensive retrospective study is to assess issues related to the management of skull base defects associated with CSF rhinorrhea involving the nose and paranasal sinuses. METHODS: A retrospective review of CSF leak management was conducted. This study included patients with CSF rhinorrhea managed by the Department of Otolaryngology, Medical College of Wisconsin, Milwaukee, WI, from 1992 to 2002. Data collected included site of leak, surgical approach, and any recurrence of leak. RESULTS: Fifty-seven CSF leaks occurred in 53 patients with CSF rhinorrhea originating from the nose or paranasal sinuses. Twenty-eight of the 53 had iatrogenic injuries resulting in CSF rhinorrhea, 16 had leaks from trauma, and 13 developed spontaneous CSF leaks. Ten patients responded to nonoperative management with bed rest with or without lumbar drain placement. Forty-three patients with 47 leaks underwent surgical repair of CSF rhinorrhea, of which 38 resolved after initial repair. Five of these patients developed recurrent CSF leaks at the repair site but resolved with subsequent surgery. Of these, two initially presented with spontaneous CSF leaks, one patient had a gunshot wound with massive skull base injury, and two recurred after repair of an iatrogenic injury. Factors associated with failure included lateral sphenoid leaks and elevated body mass index (BMI). DISCUSSION: Multiple approaches to the management of CSF rhinorrhea can be successful. An endoscopic repair results in resolution of CSF rhinorrhea in the majority of cases. Patients with spontaneous CSF rhinorrhea, elevated BMI, lateral sphenoid leaks, and extensive skull base defects are at increased risk for recurrence. Alternative management options may need to be considered in these cases.

Chronic sinusitis and gastroesophageal reflux: are they related?

PURPOSE OF REVIEW: Gastroesophageal reflux has been implicated in many disorders affecting the upper airway over the past three decades. This article reviews the recent literature regarding the relationship of chronic rhinosinusitis to gastroesophageal reflux. RECENT FINDINGS: Recent studies have demonstrated that patients with chronic rhinosinusitis have an increased prevalence of gastroesophageal reflux. In addition, many patients (especially children) have had improvement in their chronic sinonasal symptoms after therapeutic trials of antireflux therapy. SUMMARY: It is possible that gastroesophageal reflux plays a role in some patients with chronic rhinosinusitis; thus, evaluation and treatment should be considered in this patient population.

Skin cancer and quality of life: assessment with the Dermatology Life Quality Index.

BACKGROUND: Quality of life (QOL) has been identified as an important outcome in cancer research, yet the most common malignancy among humans, nonmelanoma skin cancer (NMSC), has been poorly studied in this regard. OBJECTIVE: To determine whether change occurred in the QOL of NMSC patients after surgery using a general, validated dermatology QOL instrument: the Dermatology Life Quality Index (DLQI). METHODS: A prospective study was conducted on 121 consecutive patients referred to a dermatologic Mohs surgery clinic with NMSC of the head and neck. QOL assessment was performed using the DLQI before (n=121) and after surgical treatment at 4 months (n=101). RESULTS: QOL scores demonstrated little handicap at initial diagnosis. The total DLQI scores showed little change over time, but an item analysis revealed that 2 of the 10 items demonstrated statistically significant change over time, with QOL improving after treatment-decreased painfulness/itchiness/soreness and less necessity to use concealing clothing. CONCLUSIONS: General dermatology QOL instruments demonstrated minimal handicap at initial diagnosis and little change after treatment of NMSC. Although the associations were modest, improvement in some aspects of well-being after treatment of NMSC was demonstrated. A more disease-specific instrument may be necessary to study this disease process further.

Quality of life assessment in nonmelanoma cervicofacial skin cancer.

OBJECTIVES/HYPOTHESIS: Health-related quality of life (QOL) assessment of patients with nonmelanoma skin cancer is poorly understood. The objectives of the study were to determine the general QOL of patients with cervicofacial skin cancer and to identify patient, clinical, and preventive behavior variables associated with patients' QOL. STUDY DESIGN: Cross-sectional study of 121 consecutive patients (65 female and 56 male patients) presenting to a dermatological Mohs surgery clinic with nonmelanoma skin cancer of the head and neck. METHODS: Quality of life assessment was performed before counseling or treatment. Measures included the Medical Outcomes Study Short Form 36-item Health Survey (SF-36) and the Functional Assessment of Cancer Therapy-General (FACT-G). RESULTS: Both instruments demonstrated good internal consistency as measured by Cronbach's alpha (SF-36, alpha = 0.45-0.91; FACT-G, alpha = 0.61-0.90). The SF-36 scores were similar to historical norms. Bivariate analysis indicated significant correlation coefficients between QOL and patients' coexisting illnesses and medical risk factors. Sun-protective behaviors were associated with better QOL. The relationship appeared to be minimally influenced by patients' sociodemographic characteristics and disease-related variables (size, location, extent). CONCLUSIONS: Sun-protective behaviors were positively associated with certain QOL subscale scores in the population in the study. General QOL instruments demonstrated minimal impact of nonmelanoma skin cancer on patients at initial diagnosis. However, general measures may not be sensitive to the impact of nonmelanoma skin cancer. The development of a more disease-specific instrument may be necessary to evaluate this disease process.

Quality of life assessment in nasal airway obstruction.

OBJECTIVES/HYPOTHESIS: Quality of life (QOL) assessment of patients with nasal obstruction has not been well studied. The objectives of the study were to determine the QOL of patients with nasal obstruction, to identify baseline variables predictive of patients' QOL, and to examine the relationship of QOL scores with patient assessment of nasal obstruction. STUDY DESIGN: Preliminary, cross-sectional study of a larger, prospective investigation. METHODS: Forty individuals met the criteria for inclusion. Participants were required to have a surgically treatable diagnosis of septal deviation, nasal valve collapse, and/or turbinate hypertrophy. Quality of life assessment was performed using the Rhinoconjunctivitis Quality of Life Questionnaire and the Rhinosinusitis Disability Index. Demographic data, along with patient assessment of nasal obstruction with a visual analogue scale, were recorded. RESULTS: Both instruments demonstrated good inter-item correlation as measured by Cronbach's alpha. Demographic variables, previous nasal surgeries, and comorbid conditions were not significantly correlated with QOL scores with either instrument. Correlations between visual analogue scale scores and the Rhinoconjunctivitis Quality of Life Questionnaire "sleep" (correlation coefficient [r] = 0.35, P =.02) and "nasal symptom" (r = 0.36, P =.02) domains demonstrated a trend toward significance. Patients with nasal valve collapse reported higher visual analogue scale scores for nasal obstruction compared with those with septal deviation alone (P <.01). CONCLUSIONS: Patients with nasal valve collapse demonstrated greater perception of nasal obstruction than those with septal deviation alone. The Rhinoconjunctivitis Quality of Life Questionnaire appears to be a more sensitive instrument than the Rhinosinusitis Disability Index for patients with nasal obstruction. However, existing measures may lack sensitivity in estimating the QOL of patients with nasal obstruction. A disease-specific instrument for nasal obstruction may be necessary to further evaluate this disease process.
