Methodologic assessment of studies on endoscopic sinus surgery.

BACKGROUND: Functional endoscopic sinus surgery (ESS) has become the procedure of choice for surgical treatment of chronic rhinosinusitis. Does the published literature support the claims of greater efficacy than medical treatment alone or older sinus procedures? OBJECTIVE: To analyze the methodology of the published literature regarding the efficacy of ESS. DATA SOURCES: MEDLINE search for primary studies published in 1987 through 2001, written in the English language, reporting results on more than 100 patients, using the MeSH (medical subject headings) terms sinusitis [subheadings surgery or therapy] and endoscopy. STUDY SELECTION: Of 512 studies initially identified, 29 studies met the inclusion and exclusion criteria for further assessment of methodologic criteria. An additional 6 studies were found when the reference lists of reviews or included studies were searched. DATA EXTRACTION: Articles were evaluated for 4 core (inclusion/exclusion criteria, control group, intervention, and clear outcome measure) methodologic criteria essential to the determination of efficacy of ESS. Eight additional methodologic criteria were also used to rate the articles. DATA SYNTHESIS: Three studies met all 4 core methodologic criteria. Only 4 of 35 studies used a control group to evaluate efficacy of ESS to treat chronic sinusitis. Mean number of criteria met was 7.2, with a range of 2 to 11. CONCLUSIONS: Absence of a control group is the most important reason that studies are unable to scientifically assess the comparative efficacy of ESS to medical therapy or other sinus procedures. The methodologic criteria described here can be used to evaluate studies of interventions for other disorders.

Prognostic staging system and therapeutic effectiveness for recurrent or chronic sinusitis in children.

OBJECTIVE: We sought to assess the clinical status of pediatric sinusitis patients after a minimum of 2 years follow-up and to evaluate relative treatment effectiveness. Study design We conducted a medical record review of 308 patients, with a 2-year follow-up questionnaire. RESULTS: Overall, 55% of children were "much improved." A 4-stage prognostic system was developed and used to compare results in 133 patients who had not responded to medical treatment and who had positive sinus computed tomography scans. Endoscopic sinus surgery (ESS) had no apparent advantages in stages I and IV, but in stages II and III, rates of "much improved" for ESS versus medical therapy were 79% versus 54% and 68% versus 42%, respectively. CONCLUSION: These results suggest that ESS may be particularly effective for patients from intermediate prognostic stages. SIGNIFICANCE: This type of prognostic staging and evaluation of treatment effectiveness is necessary and important in chronic sinusitis, where randomized trials are unlikely to be performed.

Vestibular dysfunction after cochlear implantation.

OBJECTIVE: To determine the prevalence, symptom characteristics, and potential risk factors for vestibular symptoms after cochlear implantation. STUDY DESIGN: Case-control study design embedded within an ongoing cohort of patients undergoing implantation. SETTING: Academic medical center cochlear implant research program funded by the National Institutes of Health. PATIENTS: Seventy five eligible consecutive patients undergoing cochlear implantation. INTERVENTION: Medical record review. MAIN OUTCOME MEASURE: Recorded symptoms of vestibular symptoms after cochlear implantation. Subjects with vestibular symptoms were considered case subjects; those without vestibular symptoms were considered control subjects. RESULTS: Twenty-nine of 75 (39%) patients experienced dizziness postoperatively. Four patients experienced a single, transient acute vertigo attack occurring less than 24 hours after surgery. The majority, 25 patients, experienced delayed, episodic onset of vertigo. The median (interquartile range) time of delayed onset was 74 (26-377) days after implantation. Delayed dizziness manifested as spontaneous episodic or positional vertigo. Preoperative dizziness, age at implantation, and age at onset of hearing loss were significantly greater in the dizzy group. Preoperative electronystagmography did not differentiate between groups. CONCLUSIONS: Thirty-nine percent (29/75) of subjects with implants were dizzy after implantation. The majority of subjects experienced dizziness in a delayed episodic fashion. Dizziness was not related to implant activation. It seemed that delayed dizziness was not related to immediate surgical intervention but could result from chronic changes occurring in the inner ear; there was some suggestion this could take the form of endolymphatic hydrops.

Development of a new head and neck cancer-specific comorbidity index.

BACKGROUND: Most patients with head and neck squamous cell carcinoma are older and may have coexistent or comorbid diseases. OBJECTIVES: To determine the prognostic impact of individual comorbid conditions in patients with head and neck cancer, to combine the individual comorbid conditions to form a new a head and neck-specific comorbidity instrument, and to compare it with the Modified Kaplan-Feinstein Index to determine if the new disease-specific instrument offers any improvement in survival prediction over a general comorbidity index. DESIGN: Retrospective review of medical records. POPULATION: The study population comprised 1153 patients with biopsy-proven, newly diagnosed squamous cell carcinoma of the oral cavity, oropharynx, or larynx. RESULTS: Seven comorbid conditions (congestive heart disease, cardiac arrhythmia, peripheral vascular disease, pulmonary disease, renal disease, cancer controlled, and cancer uncontrolled) were significantly related to survival. These comorbid conditions were assigned integer weights to reflect their relative prognostic importance and combined to create the new Washington University Head and Neck Comorbidity Index (WUHNCI). Survival was significantly related to levels of comorbidity severity as defined by the WUHNCI. The WUHNCI predicted survival better than the Modified Kaplan-Feinstein Index despite containing far fewer ailments. CONCLUSIONS: Comorbidity is an important feature of the patient with head and neck cancer. The WUHNCI can be used for retrospective review or prospective outcomes research.

Psychometric and clinimetric validity of the 20-Item Sino-Nasal Outcome Test (SNOT-20).

A valid measure of rhinosinusitis health status and quality of life is required for the complete assessment of treatment effectiveness. The purpose of this study was to analyze the psychometric and clinimetric validity of the 20-Item Sino-Nasal Outcome Test (SNOT-20), a disease-specific, health-related quality-of-life measure for rhinosinusitis. The SNOT-20 is a modification of the 31-Item Rhinosinusitis Outcome Measure, and it contains 20 nose, sinus, and general items. To complete the instrument, patients indicate how much they are affected in each area and identify the 5 most important items. The SNOT-20 was completed by 102, 72, and 46 patients at the initial visit and at 6 months and 1 year after treatment commencement, respectively. Cronbach's alpha was 0.9; test-retest scores were highly correlated (r = 0.9). Patients who were more affected had greater SNOT-20 scores (P < 0.002), and patients who had improved had greater change scores (P < 0.04). Items identified as important had greater scores (P < 0.0001) and showed greater change scores (P < 0.0002). The SNOT-20 is a valid outcome measure for patients with rhinosinusitis; it describes the health burden and is sensitive to clinical change.

Long-term outcome of facial growth after functional endoscopic sinus surgery.

OBJECTIVE: We sought to determine whether functional endoscopic sinus (FES) surgery performed in children with chronic rhinosinusitis alters facial growth. STUDY DESIGN AND SETTING: This was a retrospective age-matched cohort outcome study performed at a tertiary care hospital. RESULTS: Sixty-seven children participated. There were 46 boys and 21 girls, and the mean age was 3.1 years at presentation and 13.2 years at follow-up. There were 46 children who underwent FES surgery and 21 children who did not undergo FES surgery. Quantitative anthropomorphic analysis was performed using 12 standard facial measurements. A facial plastic expert performed qualitative facial analysis. Both quantitative and qualitative analyses showed no statistical significance in facial growth between children who underwent FES surgery and those who did not undergo FES surgery. CONCLUSIONS: In this study, there was no evidence that FES surgery affected facial growth. SIGNIFICANCE: These results will aid physicians when discussing with parents the risks of FES surgery.

Impact of comorbidity on survival after surgical resection in patients with stage I non-small cell lung cancer.

OBJECTIVE: As the mean age in patients with non-small cell lung cancer increases, the proportion of patients with serious comorbidity who are considered for surgical resection also increases. Patients with non-small cell lung cancer have been shown to have a higher burden of comorbidity than do patients with tumors of other sites, such as breast, prostate, colon, and head and neck. The goal of this review was to determine the impact of comorbidity on postoperative and long-term survival after surgical resection in patients with stage I non-small cell lung cancer. METHODS: A database analysis of our hospital's tumor registry included 451 patients who underwent surgical resection for pathologic stage I non-small cell lung cancer between January 1, 1994, and December 31, 1999. Comorbidity severity was prospectively determined with the Kaplan-Feinstein Index. Survival data were collected for each patient from the date of operation, with a mean duration of follow-up of 35.7 months. Bivariate statistics and Cox proportional hazards model analyses were used. RESULTS: The mean age was 64.4 years, and 249 (55%) patients were male. The distribution of overall comorbidity severity was none, 142 (31.5%); mild, 150 (33.3%); moderate, 115 (25.5%); and severe, 44 (9.8%). The overall in-hospital mortality was 2.2% (n = 10/451). There was a nonsignificant trend toward higher hospital mortality with greater comorbidity: none, 0.7% (n = 1/142); mild, 3.3% (n = 5/150); moderate, 0.9% (n = 1/115); and severe, 6.8% (n = 3/44, P =.055). Kaplan-Meier estimated survivals at 3 years for each level of comorbidity were as follows: none, 85.6%; mild, 74.8%; moderate, 68.8%; and severe, 70.0% (P <.002). After adjustment for age, sex, T status, and tumor histologic type, the relative risks of death as a function of comorbidity were mild, 1.44 (95% confidence interval 0.89-2.34); moderate, 2.28 (95% confidence interval 1.43-3.65); and severe; 1.94 (95% confidence interval 1.023-3.70). CONCLUSIONS: Comorbidity has a significant impact on survival after surgical resection of patients with stage I non-small cell lung cancer. These data may help to explain the lower than expected survival results for patients after surgical resection for stage I non-small cell lung cancer.
