“…However, current FPMM detected the obstructive sites of OSAS in patients for diagnosis according to the examiner's subjective judgment, which results in great differences in predicting surgical effectiveness [11,12] , whereas calculation of the relative area of the FPMM image is easy with computer-aided graphic processing. The key to our approach was standardized image sampling and calibration.…”

Objective: To investigate the upper airway (UA) characteristics of patients with obstructive sleep apnea syndrome (OSAS) using computer-assisted fiberoptic pharyngoscopy with Müller’s maneuver (CFPMM). Methods: The pharyngeal cavity were measured and calculated by CFPMM in 30 OSAS patients and 30 controls. The correlation between UA anatomy and polysomnography data was analyzed. Results: CFPMM can measure the cross-section area of UA accurately. All OSAS patients had minimal cross-section areas of pharyngeal apertures below 40 mm² during Müller’s maneuver and 60% of cases had complete occlusion. Obstruction sites at the velopharynx were observed in all cases and 40% had multiple obstruction sites. Diminished pharyngeal apertures and increased collapsibility were associated with increased rates of apnea and hypopnea index (p < 0.05). Conclusion: CFPMM is able to evaluate UA’s characteristics and help determine the site of obstruction. Complete occlusion of UA during Müller’s maneuver is the criterion to determine the obstruction site in OSAS patients.

Aim:The author present a retrospective descriptive study of 60 patients with sleep obstructive ventilatory disturbance who have taken medical advice at the Centro Campinas de Otorrinolaringologia e Cirurgia de Cabeça e Pescoço during a period of three years. All the patients have been examined after standardized protocol and decisions related to the treatment have been taken after systematic multidisciplinary discussion. Study design: clinical retrospective. Material and method: The patients were distributed into two groups according to the proposal of surgical and non-surgical treatment. After so, they were studied according to the model of treatment proposed and the main propaedeutic findings: respiratory disturbance index (RDI), body mass index (BMI), cephalometric analysis and Müller maneuver. The main features were compared -isolated or in association -with the model of treatment proposed. Conclusion: Amongst several conclusions obtained, the most important were: surgical and non-surgical treatment were indicated almost in the same proportion for of snoring; surgical treatments were most indicated for snoring and Apnoea-Hipopnoea Syndrome, despite of its modality; RDI, BMI and cephalometric analysis and Müller maneuver had no influence at any therapeutic modality; the therapeutic decision was taken after standardized protocol and systematic multidisciplinary discussion, where each case was discussed individually.

“…Evaluation of patients with disordered breathing sleep usually include physical examination [1], fibro-optic examination with Muller maneuver [2,3], lateral cephalometry [4] and polysomnography [5]. With the exception of polysomnography most of these methods depend on the static evaluation of the upper airway as they performed on the awake patient.…”

To evaluate the reliability of drug induced sleep endoscopy (DISE) in identifying levels and degrees of severity of obstruction in sleep disordered breathing (SDB) patients. Patients with obstructive sleep apnea syndrome (OSAS) and habitual snoring diagnosed by polysomnography assessed by history and Epworth Sleepiness Scale (ESS), modified Malampatti index, Friedman staging system, Assessment of the Body mass index (BMI), neck circumference (NC), Müller maneuver (MM) and DISE using the NOHL (nose, oropharynx, hypopharynx and larynx) classification system. Our results revealed 66 patients, 34 males and 32 females with ages ranging from 23 to 58 years. BMI showed that 86.4 % of cases were obese with mean BMI (35.1 ± 5.6) ranging from (24 -50 kg/m 2 ). NC showed large NC (> 37cm) in 100 % of females while it was large (> 43 cm) in only 29.4 % of males. The mean apnea/hypopnea index was 10.7 ± (11.8/h). Obstruction at oropharyngeal level was 82% of the patients with grades ranging from 50 to 100%followed by obstruction at the level of hypopharynx in 68%. Only 13.6% showed supraglottic obstruction due to flappy epiglottis. Almost all patients showed multilevel obstruction with different grades. We found no correlation between the results of DISE, MM and classic ENT evaluation techniques. DISE treatment recommendations was different in 82% of patients at the oropharyngeal level and in 39% at the hypopharyngeal level than those of MM, but was nearly the same regarding supraglottic obstruction.Conclusion: DISE is a reliable tool of upper airway collapse assessment leading to better treatment recommendations for SDB patients.
