In sleep apnea/hypopnea syndrome (SAHS) a superior airway collapse can occur in the anteroposterioror lateral direction. The primary or secondary decrease in the tone of the dilating muscles of the pharynx, due to the negative pressure produced by the contraction of the diaphragm cause the collapse. Pharyngoplasty surgical techniques try to improve lateral collapse by repositioning the muscles that constitute the pharyngeal lateral wall, mainly the palatopharyngeal (PP), palatoglossal (PG) and u...

Obstructive sleep apnea (OSA) is a sleep respiratory disorder characterized by an intermittent complete or partial collapse of the upper airways, resulting in apnea and hypopnea events. Breathing pauses cause acute adverse effects including oxyhemoglobin desaturation, changes in blood pressure and heart rate, increased sympathetic activity, cortical arousals (micro awakenings) and sleep fragmentation. There is limited evidence to support the fact that mild OSA can have negative health consequenc...
Visualizing of Upper Respiratory Tract during Physiologicaly Sleep
Article Type: Case Report | First Published: November 14, 2020
Obstructive sleep apnea is a disease consisting of episodes of partial or complete closure of the upper airway that occur during sleep and lead to breathing cessation defined as a period of apnea more than 10s. Symptom include restlessness, snoring, recurrent awakening, morning headache and excessive day time sleepiness. Diagnosis of obstructive sleep apnea is based on sleep history and polysomnography. Continuous positive airway pressure (CPAP) is the gold-standard treatment in severe OSAS. In ...

Twenty four patients with evidence of OSA on polysomnography were included. In all patients the major cause of obstruction was due to concentric collapse of velopharynx as evidenced on Muller Maneuver (MM) and Drug Induced Sleep Endoscopy (DISE). All had non-adherence to (CPAP) therapy and underwent Barbed Palato Pharyngoplasty (BPP) for correction of concentric collapse of velum. Apnoea-Hypopnoea Index (AHI), Lowest Oxygen Saturation (L-sat), Epworth Sleepiness Score (ESS), Visual Analog Score ...
