The impact of atopy, sinus opacification, and nasal patency on quality of life in patients with severe nasal polyposis.

OBJECTIVES: Nasal polyposis has a great impact on the quality of life. The aim of this study was to evaluate the association between quality of life and atopy, sinus opacification, and nasal patency in severe nasal polyposis. METHODS: One hundred nine patients completed the Medical Outcome Study Short Form-36 (SF-36) survey. Symptoms, polyp size, atopy, nasal patency, and sinus opacification were also scored. RESULTS: Patients showed worse scores in all SF-36 domains, except for physical functioning, compared with Spanish population. Atopic patients had worse scores in role physical, body pain, vitality, and mental health than nonatopic patients. Atopic patients showed lower physical component summary (44.7 +/- 1.1) and mental component summary (38.4 +/- 1.0) than nonatopic patients (48.3 +/- 1.6, 40.6 +/- 1.3; P < 0.05), respectively. There were no correlations between quality of life and symptoms, polyp size, CT scan, nasal patency, and atopy. CONCLUSION: Nasal polyposis has a considerable impact on quality of life and atopy worsens this impact. EBM RATING: C-4.

A short course of oral prednisone followed by intranasal budesonide is an effective treatment of severe nasal polyps.

BACKGROUND: Nasal polyposis is an inflammatory disease of unknown etiology. This study aimed to evaluate the effect of a short course of oral prednisone followed by intranasal budesonide on nasal symptoms, polyp size, nasal flow, and computed tomography scan. METHODS: Eighty-four patients with severe nasal polyps were included. After a steroid washout period, patients were randomized into two groups: group A (n = 63) received oral prednisone for 2 weeks and group B (n = 21) did not receive any steroid treatment. Patients from group A received intranasal budesonide for 12 weeks. RESULTS: Atopy was positive in 36.8% of patients. Blood eosinophilia was higher in asthmatic (7.2 +/- 0.7%, P < .05) than in nonasthmatic (3.0 +/- 0.4%) patients. Asthmatic patients showed higher scores on nasal obstruction and loss of smell than nonasthmatics. Oral steroids caused a significant improvement in all nasal symptoms and improved polyp size (2.1 +/- 0.1, P < .05) and nasal flow (560 +/- 35 cm/s, P < .05) compared with nontreated patients (2.8 +/- 0.1 and 270 +/- 34 cm/s, respectively). Intranasal budesonide maintained the improvement on nasal symptoms, polyp size, and nasal flow. Steroid treatment reduced the computed tomography scan score (15.4 +/- 1, P < .05) compared with before treatment (18.2 +/- 0.8). CONCLUSION: A short course of oral steroids improved all nasal symptoms, polyp size, and nasal flow, whereas intranasal steroid maintain this effect.

Severe nasal polyposis and its impact on quality of life. The effect of a short course of oral steroids followed by long-term intranasal steroid treatment.

OBJECTIVES: Nasal polyposis is not a life-threatening disorder but has a great impact on the quality of life. Steroids constitute the first line of treatment of nasal polyps. The aims of this study were to evaluate the quality of life in nasal polyp patients after: (1) a short course of oral steroids; and (2) a long-term treatment with intranasal steroids. METHODS: Patients with severe nasal polyps received either oral prednisone (n = 60) or no steroid treatment (control group, n = 18) for 2 weeks. Patients treated with steroids were also followed-up and evaluated after 12, 24, and 48 additional weeks with intranasal budesonide treatment. RESULTS: Patients with nasal polyps showed worse scores on all SF-36 domains, except for physical functioning, compared to the Spanish general population. After two weeks, patients treated with oral prednisone demonstrated a significant improvement (p < 0.05) in all impaired QoL domains compared to both control group and baseline. The mental component summary (51.0 +/- 1.2, p < 0.05) and physical component summary (51.0 +/- 0.9, p < 0.05) were improved compared to both control group and baseline. The improvement of all SF-36 domains was sustained by intranasal budesonida (p < 0.05) after 12, 24, and 48 weeks. Nasal obstruction, sense of smell, and polyp size also improved after both the oral short course and the intranasal long-term steroids treatment (p < 0.05). CONCLUSION: These results suggest that the treatment with a short-course of oral steroids improves the quality of life of patients with severe nasal polyps and that this effect is maintained by a long-term treatment with intranasal steroids.

Barcelona Smell Test - 24 (BAST-24): validation and smell characteristics in the healthy Spanish population.

OBJECTIVES: Smell tests for clinical use have been developed in different countries, but no single test has gained general acceptance. The objectives of the study were to evaluate the smell outcomes in a Spanish population. METHODS: A prospective study on healthy volunteers (n = 120) without olfactory disturbances was performed. The volunteers were differentiated by gender, age, and smoking habit groups. We used a new olfactory test, the Barcelona Smell Test 24 (BAST-24) that consists of 24 odours scoring smell detection, identification, and forced choice. RESULTS: Volunteers showed the highest scores on smell detection for both 1st (99%) and 5th cranial nerve (98%) odours. Spontaneous smell identification (54.7% and 59.3%) and forced choice (72.2% and 42.6%) scores were lower than those of smell detection, for both 1st and 5th cranial nerves respectively. On smell identification, volunteers scored higher in the left than in the right nostril. Females had better smell identification for both 1st and 5th cranial nerves (62.8%, 66.7%) than males (50.3%, 58.8%). Non-smokers had higher scores (65%) than smokers (59%) on smell identification for the 5th CN. CONCLUSIONS: For smell identification, females, non-smokers, and left nostril had higher scores than males, smokers, and right nostril respectively. BAST-24 is a good and reliable method to test the olfactory function in the clinical practice.

The impact of asthma and aspirin sensitivity on quality of life of patients with nasal polyposis.

BACKGROUND: Nasal polyposis is not a life-threatening disease but may have a great impact on patient's quality of life. OBJECTIVE: To investigate the impact of nasal polyps on quality of life compared with the Spanish general population using the SF-36 questionnaire; and to evaluate the impact of asthma and aspirin sensitivity on quality of life in patients with nasal polyposis. METHODS: We included 130 patients with nasal polyposis and evaluated nasal symptom, CT scan, polyp size, and quality of life. RESULTS: In comparison with the Spanish general population, patients with nasal polyposis had worse scores on all SF-36 domains except for physical functioning. Asthmatic patients with nasal polyposis had worse quality of life than nonasthmatic patients on role physical, body pain, and vitality (p < 0.05). The authors found no significant differences on quality of life, nasal symptoms, polyp size, and CT scan scores between patients with aspirin-tolerant and aspirin-sensitive asthma. CONCLUSION: These results suggest that nasal polyposis has a considerable impact on quality of life. Moreover, asthma but not aspirin sensitivity has an additional negative impact on the quality of life of patients with nasal polyposis.

Inflammatory myofibroblastic tumor in the larynx: clinicopathologic features and histogenesis.

Inflammatory myofibroblastic tumor is extremely rare in the larynx and can mimic a malignant process. We present the case of a 62-year-old male who required tracheotomy due to rapidly progressive stridor. Laryngoscopy showed an exophytic, occlusive tumor located in the right true vocal cord. CT showed an expansive mass measuring 2 x2 x1.3 cm3 and occupying the anterior commissure, with glottic progression to the right true vocal cord. The tumor was completely resected with a CO2 laser via a transoral approach. Histologic examination demonstrated extensive ulceration with the presence of granulation tissue. The specimen was mainly composed of spindle cells arranged in a fasciculated pattern with a myxoid background and focal hyalinization. Immunohistochemical studies revealed positivity of spindle cells to vimentin, muscle-specific actin and smooth muscle actin. The patient showed no evidence of disease 24 months after surgery.

Epiglottitis and necrotizing fasciitis: a life-threatening complication of infectious mononucleosis.

Life-threatening cervical complications associated with infectious mononucleosis are rare. The combination of acute epiglottitis and subsequent necrotizing fasciitis of the head and neck in a patient with infectious mononucleosis has not been reported to date.A 47-year-old female with infectious mononucleosis and epiglottitis was admitted to hospital for i.v. therapy. Owing to her poor clinical condition and the spread of the infection to the throat and superior mediastinum, as evidenced by CT, a cervical debridement was performed. After cervical debridement, histological findings were consistent with necrotizing fasciitis. The bacteria identified were Streptococcus viridans, Veilonella spp. and Capnocytophaga spp. The patient was hospitalized for 33 days.Mononucleosis, usually a benign condition, may be associated with life-threatening septic complications in the neck and chest. Serial CT or MRI scans are necessary to assess the development of the infection in the deep layers of the neck. Rapid medical treatment, extensive surgical debridement and intensive care are vital.

Cerebellopontine angle and internal auditory canal metastasis from ductal carcinoma of the breast.

This is the first formal case report of internal auditory canal and cerebellopontine angle metastasis from infiltrative ductal carcinoma of the breast. Only three previous cases have been reported of isolated metastasis in the cerebellopontine angle and internal auditory canal from breast cancer. Currently, no therapeutic guidelines for isolated metastasis from breast cancer in this location exist. We report a case and review the current literature in order to help characterize the clinicopathologic features and management. A 72-year-old female with a 5-year history of left infiltrative ductal carcinoma of the breast reported progressive left-sided facial palsy and ipsilateral hearing loss accompanied by the development of tinnitus and unsteadiness during the previous 3 months. MRI identified a lesion in the cerebellopontine angle and internal auditory canal. The lesion was completely excised via a retrosigmoidal approach and adjuvant radiotherapy was used subsequently. The patient remains well 18 months after treatment, with no evidence of recurrence on repeat MRI. The rapid evolution of symptoms involving the Vth, VIIth or VIIIth cranial nerve, or multiple cranial nerves, is suggestive of a malignant lesion of the cerebellopontine angle and/or internal auditory canal. A previous history of neoplasm is important due to the possibility of a metastasis. Cerebellopontine angle metastasis can be found many years after the initial diagnosis of breast neoplasm. Surgery and adjuvant radiotherapy seems to be a good choice for the treatment of patients with this specific type of metastasis.

Closure of cerebrospinal fluid leaks prevents ascending bacterial meningitis.

INTRODUCTION: Endoscopic surgery of the anterior skull base has become the standard procedure for the repair of cerebrospinal fluid (CSF) leaks of various origins. Closure of the leaks is believed to prevent ascending meningitis, although no report has specifically shown this. MATERIAL AND METHODS: Retrospective chart study of 39 patients who underwent endoscopic skull base surgery from 1/1993 to 11/2002. SETTING: Tertiary University Hospitals. OUTCOME MEASUREMENT: Incidence of ascending meningitis after endoscopic skull base repair in patients with anterior skull base defects associated or not with meningitis and CSF leak. RESULTS: Forty-one endoscopic repairs of anterior skull base defects of various origins were performed in 39 patients. Fifteen (36.5%) had suffered bacterial meningitis before surgery. Mean follow-up was 65 months (range 22-120). The defect was repaired using an "underlay" technique with lyophilized dura (n=11) or fascia lata (n=30), and covered with free mucosal grafts from either the middle or the inferior turbinates. Closure was achieved in 40/41 cases at first attempt. No recurrence of ascending bacterial meningitis was observed during follow-up in any of the fifteen patients who had previously presented with a CSF leak or skull base defect with meningitis. Also, no new bacterial meningitis occurred in all other patients. One case of meningoencephalocele of the lateral sphenoid wall developed a recurrent CSF fistula associated with bacterial meningitis two years after endoscopic repair, requiring endoscopic revision surgery. No patient received vaccination in this series. DISCUSSION: Closure of active CSF leaks and reconstruction of skull base defects without CSF-leak in patients with prior ascending bacterial meningitis seem to provide excellent long-term results with neither recurrence of ascending meningitis nor incidence of meningitis in the other patients, unless a CSF leak re-appears. Conservative treatment of CSF leaks may lead to bacterial meningitis, therefore surgical closure of leaks or defects at the skull base should be considered treatment of choice to prevent ascending meningitis.

Endoscopic resection of juvenile angiofibromas--long term results.

OBJECTIVE: To evaluate the long term outcome after endoscopic endonasal resection of juvenile nasopharyngeal angiofibromas (JNA). METHODS: Retrospective study of a series of 21 consecutive patients undergoing endoscopic resection of JNA (type I - IIIa according to Fisch) at two Hospital Centers between 1993 and 2002. Mean follow-up was 51.7 months (range 5-120). Extension to the medial aspect of infratemporal fossa and retromaxillary space was no contraindication against an endonasal endoscopic approach. In three cases of type IIIa tumours a computer assisted intraoperative guiding system was applied (ENTrak, GE Medical, Lawrence, USA). RESULTS: Fifteen patients (71.4%) were free of disease after one endoscopic resection. Three patients (14.3%) had an unmistakable recurrence with the need for further treatment at 6, 14, and 23 months, respectively. Two of the three recurrent tumours have been successfully resected endoscopically, one case was treated with gamma knife. In three patients (14.3%) postoperative MRI showed localized enhanced signal, presumably minimal persistent tumour tissue. Without further treatment all of these patients remained free of symptoms and MRI follow up showed no tumour growth over three, five and ten years, respectively. No postoperative long term sequela was observed. CONCLUSIONS: Resection of nasopharyngeal angiofibromas type I-IIIa can be safely achieved endoscopically. The advantage of this minimally invasive technique is avoidance of external scars and low morbidity. The intraoperative computer assisted guiding system ENTrak was highly accurate and provided substantial help in selected cases.

Laryngeal solitary fibrous tumor treated with CO2 laser excision: case report.

The solitary fibrous tumor is an uncommon unilateral benign lesion that usually arises from the pleura. Recently, these tumors have been described in many other locations, such as the mediastinum, head and neck, orbit and urogenital system. To date, only two cases of solitary fibrous tumor arising from the larynx have been reported in the scientific literature. We describe a new case of laryngeal solitary fibrous tumor localized at the right false vocal fold. A 29-year-old man presented with a 6-month history of progressive hoarseness and foreign body sensation in the throat. A mass lesion was recognized in the right false vocal fold, and CT scan demonstrated a large, well-defined tumor without signs of infiltration. The tumor was removed by transoral CO(2) laser surgery. The definitive diagnosis was obtained by immunohistochemical analysis that showed vimentin and CD34-positive cells. The patient remains free of tumor after 15 months of follow-up.

Predictive values for aspiration after endoscopic laser resections of malignant tumors of the hypopharynx and larynx.

BACKGROUND: CO2-laser surgery is a relatively new treatment for selected carcinomas of the upper aerodigestive tract. The purpose of our study was to evaluate prospectively the functional results for swallowing after CO2-laser resections. METHODS: The sample was composed of 210 consecutive patients with malignancies of the larynx and hypopharynx treated with CO2 laser between February 1998 and January 2002. Endoscopic resections included all T1 and T2 tumors and selected T3 and T4 tumors. T1 glottic tumors were not included in the analysis. We assessed the need for a feeding tube and the period the tube remained in place, aspiration pneumonia, tracheotomy secondary to aspiration, the need for a permanent or temporary gastrostomy, and total laryngectomy secondary to aspiration. RESULTS: The nasogastric feeding tube was used in 23.2% of small tumors (2.5 +/- 8.04 days) and in 63% of locally advanced tumors (13.95 +/- 22.55 days). Frequency and period of storage of the feeding tube were higher in locally advanced tumors (p=.0001). Twelve patients (5.7%) had postoperative pneumonia and 59 (28.1%) had temporary postoperative cough during oral intake. Aspiration symptoms correlated with location (p=.001) and locally advanced tumors (p=.016). Eight patients (3.8%) needed a postoperative tracheotomy for severe swallowing difficulties; six (2.9%) of them were definitive and two (0.95%) temporary. Thirteen gastrostomies (6.2%) were performed to avoid severe aspirations; five of them were definitive. The need for gastrostomy correlated significantly with location (p=.002), pT3 and pT4 tumors (p=.002), age (p=.02), and postoperative radiotherapy (p=.04). No correlation was found with the period of feeding tube (p=.38), or aspiration pneumonia (p=.24). CONCLUSIONS: Endoscopic resection of laryngeal and hypopharyngeal tumors is associated with good recovery of deglutition. Many tracheotomies are avoided, the need for a feeding tube is usually reduced, and organ preservation is often feasible even in locally advanced tumors.

CO2 laser surgery: a larynx preservation alternative for selected hypopharyngeal carcinomas.

BACKGROUND: Transoral CO2 laser surgery (TLS) has demonstrated good oncologic results and low morbidity in the treatment of selected laryngeal carcinomas, but experience in hypopharyngeal carcinomas (HC) is limited. The aim of this study was to evaluate the usefulness of TLS in the treatment of selected HC. METHODS: Twenty-eight patients with HC were treated with TLS and neck dissection. Tumors with preoperative invasion of thyroid cartilage at CT, deep growth into the cervical space or tongue base, and tumors crossing the posterior midline or involving the cervical esophagus were excluded. Postoperative radiation to the neck was administered when more than one lymph node was involved, when the metastasis diameter was greater than 2 cm, or when extranodal spread was found at the pathologic study. RESULTS: The sample included two T1, 16 T2, nine T3, and one T4 tumors. Stage classification was: II, 21.4%; III, 28.6%; and IV, 50%. Four-year overall and disease-specific survival rates were 43.4% and 59.4%, respectively, with 78.5% function preservation. Nine patients (32.1%) did not need a nasogastric feeding tube. The mean duration of the feeding tube in the remaining patients was 15.27 +/- 27.3 days. We had two postoperative bleeding episodes that required endoscopic coagulation and three postoperative pneumonias caused by aspiration. CONCLUSIONS: TLS is an alternative for the treatment of selected HC associated with a high larynx preservation rate.

Treatment of 125 sinonasal tumors: prognostic factors, outcome, and follow-up.

We reviewed our experience with sinonasal cancer patients to assess the prognostic factors. Between 1974 and 1995, we enrolled 125 patients (58 + 16 years [mean age + SD]; 94 males and 31 females). Tumor stage distribution was: T1, 64 patients; T2, 36 patients; and T3, 25 patients. Surgery as a primary treatment was selected for 106 patients (55 cases of surgery alone, 40 cases of surgery plus radiotherapy, and 11 cases of surgery plus chemotherapy with/without radiotherapy). The 1-, 5-, and 10-year overall survival was 75.0%, 37.2%, and 24.7%, respectively. The parameters with statistical prognostic significance were nodal stage, locoregional failure, and tumor stage. Histological type and primary site had no prognostic value. There were no significant survival differences between surgery alone and surgery plus radiotherapy. Sinonasal tumors have a poor survival, despite early diagnosis, radical surgical resection, and strict follow-up. Radiotherapy seems not to be clearly necessary in stage T1.

Parapharyngeal angiolipoma causing obstructive sleep apnoea syndrome.

Obstructive sleep apnoea syndrome (OSAS) is the cessation of airflow with the continuance of respiratory effort during sleep. OSAS associated with a neck mass is extremely rare. Angiolipoma is a rare, benign, fatty tumour composed of mature lipocytes and multiple areas containing angiomatous elements. The treatment for an angiolipoma is surgical excision. We report the case of a 47-year-old male who presented with a history of loud snoring associated with sleep apnoea. A polysomnographic study demonstrated an apnoea-hypopnoea index of 72/h. CT showed a 3.5 x 3 x 8 cm3 hypoattenuated mass of fat density in the left parapharyngeal space causing an impression on the nasopharynx and oropharynx with a peripheral hyperintense area. A cervical transparotid surgical approach was used. A histological study led to the definitive diagnosis of angiolipomal without evidence of malignancy. After surgery, the snoring disappeared and the patient remained tumour-free after 54 months of follow-up. This is the first case in the literature of a patient with nocturnal polysomnographic-documented OSAS caused by a left parapharyngeal angiolipoma.

Particulate silicone for vocal fold augmentation: morphometric evaluation in a rabbit model.

To study the augmentation of the paralyzed vocal fold in response to the injection of particulate plastics in a rabbit model, we performed a prospective, experimental, and controlled study in 45 New Zealand rabbits with surgical vocal fold paralysis. We compared a control group (acute unilateral recurrent nerve section) with a group that underwent polytetrafluoroethylene (PTFE) injection and with another group that underwent polydimethylsiloxane (PDMS) injection. Equal volumes of implant material were injected. The animals were killed either 6 weeks or 6 months after intervention and compared by histomorphology using a digital measuring system. The injection sites showed a substantial foreign body giant cell reaction against the PDMS and PTFE, surrounded by a light, fibrous stroma. No differences in the frequency of displacement or disaggregation of implants were observed. No extrusion to the laryngeal lumen, signs of migration outside the larynx, or malignant changes were seen. No differences were found in the length of the vocal fold between the PDMS group and the PTFE group. The vocal fold was thicker in the PDMS group than in the PTFE group, but a statistically significant difference was found only for the anterior and middle thirds at 6 weeks. In the PDMS sample, the thicknesses were similar in the 6-week and 6-month subgroups. The group with injection of PDMS yielded histologic images compatible with greater and more stable medialization than did the group with injection of PTFE.
