Myofunctional assessment for obstructive sleep apnea and the association with patterns of upper airway collapse: a preliminary study.

Objectives: To organize an assessment instrument with questionnaires and myofunctional orofacial/oropharyngeal assessment for OSA patients and correlate it with the upper airway obstructive site detected during drug-induced sleep endoscopy (DISE).

Material And Methods: 29 OSA patients aged 22-65 years with an indication to undergo DISE to evaluate an alternative treatment to PAP and signed the consent form. Patients over 65 years old with maxillofacial deficiency and BMI>30 were excluded.

Obstructive Sleep Apnea: characterization of the obstructive site and type of collapse.

Obstructive Sleep Apnea is characterized by recurrent episodes of partial or complete collapse of the pharynx, followed by decreased oxyhemoglobin saturation and frequent arousals. It is regarded as a public health issue with important night and day symptoms that impact life quality. Its effects are associated with the areas of competence of Speech and Language Pathologists.

Can drug-induced sleep endoscopy (DISE) predict compliance with positive airway pressure therapy? A pilot study.

Purpose: Drug-induced sleep endoscopy (DISE) has been poorly explored as an examination to assess positive airway pressure (PAP) therapy in patients with obstructive sleep apnea (OSA). The present study aimed to identify by DISE possible characteristics related to low compliance with PAP therapy due to respiratory complaints.

Methods: Patients using PAP for OSA underwent DISE in two conditions: (1) baseline (without PAP) and (2) PAP (with the same mask and airway pressure used at home).

Correlation between the transverse dimension of the maxilla, upper airway obstructive site, and OSA severity.

Study Objectives: Acquiring a better comprehension of obstructive sleep apnea physiopathology can contribute to improving patient selection for surgical treatments. We hypothesize that maxillary transverse deficiency restricts the space available for the tongue, leading to upper airway obstruction during sleep. Our primary hypothesis was that maxillary transverse deficiency increases the prevalence of tongue collapse during drug-induced sleep endoscopy (DISE).

Nasal vs. oronasal mask during PAP treatment: a comparative DISE study.

Purpose: The present study evaluated the upper airway pattern of obstruction in individuals undergoing drug-induced sleep endoscopy (DISE) exam with positive airway pressure (PAP), and compared this effect through a nasal or oronasal mask.

Methods: Prospective study. Patients requiring PAP due to obstructive sleep apnea (OSA) were evaluated through DISE at three different moments: (1) a baseline condition (without PAP); (2) PAP treatment with a nasal mask; and (3) PAP with an oronasal mask at the same pressure.

Polysomnographic evaluation of propofol-induced sleep in patients with respiratory sleep disorders and controls.

Objectives/hypothesis: The treatment for obstructive sleep apnea syndrome (OSAS) depends on correct localization of upper airway obstruction, exception made for continuous positive airway pressure (CPAP). Drug-induced sleep endoscopy (DISE) with propofol allows this evaluation, but the drug effects on sleep parameters are not yet well established. Our objective was to study by polysomnography (PSG) whether propofol would change sleep parameters by means of a prospective cross-sectional clinical study in a tertiary hospital.

A comparison of the Fujita classification of awake and drug-induced sleep endoscopy patients.

Unlabelled: Only a few studies have compared the outcomes of patients kept awake during endoscopic examination and subjects submitted to drug-induced sleep endoscopy.

Objective: This study aimed to compare the endoscopic findings of patients submitted to outpatient endoscopy and endoscopic examination with sedation by propofol based on the Fujita Classification.

Method: This cross-sectional cohort study enrolled 34 patients.

Propofol-induced sleep: polysomnographic evaluation of patients with obstructive sleep apnea and controls.

Objective: The localization of upper airway obstruction in patients with obstructive sleep apnea (OSA) may optimize treatment. Nasoendoscopy during propofol sedation allows such an evaluation, but the effect of this drug on respiratory patterns and muscle relaxation is unknown. The objective of the present study was to determine through polysomnography whether propofol would change sleep parameters.

Surgical treatment of nasal packing refractory epistaxis.

Unlabelled: Epistaxis is the main otorhinolaryngology emergency and, in severe cases, it can lead to hemodynamic instability and be life threatening.

Aim: To evaluate factors involved in epistaxis resistant to nasal packing that needed surgical treatment, as well as post-surgical results.

Material And Methods: Retrospective study from January 2002 to August 2007.
