Systematic physical examination that was used in the present study indicated that, in combination, body mass index, modified Mallampati classification, and pharyngeal anatomical abnormalities are related to both presence and severity of obstructive sleep apnea-hypopnea syndrome. Hypertrophied tonsils were observed in only a small portion of the patients. The frequency of symptoms of nasal obstruction was high in sleep apnea patients. Further studies are needed to find the best combination of anatomical and other clinical landmarks that are related to obstructive sleep apnea.

Qual ity of life questionnaires have been increasingly used in clinical trials to help establish the impact of medical intervention or to assess the outcome of health care services. Among diseasespecific outcome measures, SNOT-22 was considered the most suitable tool for assessing chronic rhinosinusitis and patients with nasal polyps. Aims:To perform translation, cross-cultural adaptation and validation of the SNOT-22 to Brazilian Portuguese. Methods:Prospective study involving eighty-nine patients with chronic rhinosinusitis or nasal polyps submitted to functional endoscopic sinus surgery, who answered the questionnaire before and after surgery. Furthermore, 113 volunteers without sinonasal disease also answered the questionnaire. Internal consistency, test-retest reliability, measure validity, responsiveness and clinical interpretability were assessed.Results: Mean preoperative, postoperative and no sinonasal disease scores were 62.39, 23.09 and 11.42, respectively (p<0.0001); showing validity and responsiveness. Internal consistency was high (Cronbach's alpha = 0.9276). Reliability was sufficiently good, considering inter-interviewers (r=0.81) and intra-interviewers within a 10 to 14 day-interval (r=0.72). Surgery effect size was 1.55. Minimally important difference was 14 points; and scores up to 10 points were considered normal. Conclusion:The Brazilian Portuguese SNOT-22 version is a valid instrument to assess patients with chronic rhinosinusitis and nasal polyps. Braz J Otorhinolaryngol. 2011;77(5):663-9. ORIGINAL ARTICLE

Our results suggest that in patients with OSAS, myofunctional therapy may be considered as an adjuvant treatment and an intervention strategy to support adherence to CPAP.

The head and neck physical examination, considering both skeletal and soft tissue alterations, illustrated significant differences between nonapneic and OSA patients. Body mass index, modified Mallampati classification, tonsils hypertrophy, and high-arched hard palate previously related to the presence of sleep apnea in the literature showed different outcomes in nonapneic patients. Nonapneic patients had less alterations in nasal anatomy (severe septal deviation and enlarged turbinate). Skeletal parameters, such as retropositioned mandible and angle class II occlusion, were less frequent in nonapneic patients.

The anterior ethmoidal foramen and the anterior ethmoidal sulcus were anatomical landmarks present in almost 100% of the scans studied. There was a correlation between the presence of supraorbital pneumatization and AEA canal visualization.
