Consultant ENT Surgeon in Andheri, Goregaon, Malad.
Obstructive sleep apnea (OSA) is caused by repeated collapse of the upper airway during sleep. When conservative measures (CPAP, oral appliances, weight loss) fail or are not tolerated, targeted surgery of the palate, tongue base, and epiglottis can reduce obstruction, improve breathing, and decrease daytime sleepiness. Surgery is selected after a thorough evaluation including sleep study (polysomnography) and airway examination (endoscopy or drug-induced sleep endoscopy).
OSA is multifactorial. Common anatomical contributors include floppy or enlarged soft palate/uvula that narrows the oropharynx, an enlarged or posteriorly positioned tongue base that falls back during sleep, and epiglottic collapse (retroversion) which blocks the laryngeal inlet. Obesity, nasal obstruction, large tonsils, craniofacial structure, and reduced muscle tone during sleep also increase collapse risk.
Surgery is tailored to the site(s) of obstruction and may be performed singly or in combination.
Surgery can reduce apneas and symptoms but may not fully replace CPAP for all patients. Risks include pain, bleeding, infection, dysphagia, voice change, and need for revision. Recovery varies by procedure; careful preoperative assessment and postoperative follow-up including repeat sleep testing are essential.
