Modified reposition pharyngoplasty for OSAS treatment: How we do it and our results

The relevance of the lateral pharyngeal walls in the collapse of the upper airway in obstructive sleep apnea patients has been revealed in the last 20years. New surgical techniques that address this collapse have been published. The aim of this study is to show the technique that we are currently using to treat the collapse and its results.

This is a retrospective study of surgically treated OSAS patients who did not tolerate conventional positive airway pressure (CPAP) or for whom it was not indicated. After a complete physical examination either awake or under drug-induced sleep endoscopy, tonsillectomy with reposition pharyngoplasty was performed using barbed bidirectional suture and removing the supratonsillar fat. Three to 6months after surgery the subjective parameters were evaluated and a sleep study was performed.

Twenty-six patients were enrolled with a significative decrease in the AHI and also significative improvement in all the rest parameters studied. In 65.4% of the patients the AHI decreased 50% and was lower than 20/h, in 42.3% postoperative AHI was lower than 10/h. The most frequent complication was the partial extrusion of the suture.

This surgical procedure obtains statistically significant results in objective and subjective parameters of sleep apnoea without major associated complications.
