Evaluation Of Surcical Procedurwes In Management Of Obstructive Sleep Apnea Syndrome:

Ahmed Shehata El-said

Summary.gObstructive sleep apnea is a syndrome characterized by recurrent cessation of breathing during sleep leading to hypoxia and sleep fragmentation.JE/SThe nocturnal P.S.G is now the diagnostic gold standard for O.S.A but it is expensive and inconveniant.tDiagnosis of O.S.A in our study was based on simple data obtained from complete history taking and full E.N.T. examination, supplemented with flexible nasopharyngoscope and Muller’s maneuver, plain x-ray lateral view and C.T. neck axial view (oropharynx) to localized the level of obstruction. In addition to investigations including blood gases, pulmonary function tests and overnight oximetry.,e5Non surgical treatment of O.S.A includes weight reduction in the obese patient, avoidance of drugs and alcohol and relief of nasal obstruction. Continous positive airway pressure (C.P.A.P) is now the gold standard in non surgical treatment of obstructive sleep apnea and challenges tracheostomy in effectiveness.,SSurgery for O.S.A in this study includes U.P.P.P which is an effective procedure in treatment of O.S.A due to narrowing at the level of velopharyngeal sphincter. The aim of this operation is to remove excess or redundant soft tissue of the oropharynx while preserving palatalfunction.Summary.However some patients with O.S.A due to obstruction at thelevel of velopharyngeal sphincter who undergo U.P.P.P were showed no improvement due to improper diagnosis, false technique during surgery, development of restenosis due to increase in the thickness of the soft palate or appearance of airway collapse at the level of the hypopharynxafter surgery.-c Also adenoidectomy or adenotensillectomy was performed to another group of younger age who have O.S.A due to adenoidal oradenotonsillar hypertrophy with better results..V142 W°
