Abstract


Introduction: The surgical management of Obstructive sleep apnoea (OSA) is based on the site and severity of obstruction of upper airway. The present study has evaluated these factors by performing a preoperative drug induced sleep endoscopy. The study aimed at diagnosing the site of obstruction in patients with obstructive sleep apnoea symptoms by drug induced sleep endoscopy and their relation to obstructive sleep apnoea syndrome severity.Materials and Methods: The study was conducted on 30 patients aged between 12 - 65 years, presenting with symptoms of obstruc-tive sleep apnoea. All patients underwent drug induced sleep endoscopy in operation theatre under propofol sedation.Result: In our study the sleep endoscopy findings revealed multilevel obstruction in 90% patients with maximum obstruction seen at retropalatal site. All 30 patients had varying degrees of retropalatal obstruction. Hypopharyngeal obstruction was seen in 83.33%. Next common site of obstruction in patients was the base of tongue, causing obstruction in 50% of the patients. Least common sites were the nose/nasopharynx and larynx. In larynx, epiglottis was the common site of obstruction.Conclusion: Drug Induced Sleep Endoscopy is a useful tool for the preoperative assessment and surgical planning OSA patients un-dergoing surgery management.
