Surgical procedure and treatment results of pharyngoplasty CWICKs for obstructive sleep apnea.

Objective: Uvulopalatopharyngoplasty (UPPP) is performed as a surgical treatment at the oropharyngeal level for obstructive sleep apnea, but there are problems with variations in treatment effects and postoperative complications. Therefore, to improve those, we have devised and put into practice the so-called CWICKs, which is a modified version of barbed reposition pharyngoplasty as a surgical method. We outline the procedure of CWICKs and report the treatment results in comparison with the conventional UPPP.
