The obturating pharyngeal flap used in correcting velopharyngeal insufficiency has been implicated in creating difficulty in nasal breathing for some patients and/or in causing hyponasal speech, obstructive sleep apnea, and snoring. This is a case report of an individually designed removable prosthesis that positions an acrylic tube through each port lateral to the pharyngeal flap, with the goal of preventing the collapse of the ports during sleep and the consequent snoring.
The acrylic tubes maintain an opening through both lateral ports preventing the soft tissues of the lateral walls from vibrating against the pharyngeal flap (causing the snoring sound) and allowing nasal breathing.
The acrylic tubes effectively eliminated the patient's problem of snoring.
This case study demonstrates that snoring associated with a pharyngeal flap can be controlled prosthetically by maintaining an opening through the two lateral ports, preventing the soft tissues of the walls of the lateral ports from vibrating against the flap.
用于矫正腭咽闭合不全的咽瓣被认为会给一些患者造成鼻呼吸困难和/或导致鼻音过重、阻塞性睡眠呼吸暂停及打鼾。本文报告了一例个体化设计的可摘式修复体,该修复体通过咽瓣外侧的每个端口放置一根丙烯酸管,目的是防止睡眠期间端口塌陷及由此导致的打鼾。
丙烯酸管保持两个外侧端口开放,防止侧壁软组织与咽瓣振动(产生打鼾声)并允许鼻呼吸。
丙烯酸管有效消除了患者的打鼾问题。
本病例研究表明,与咽瓣相关的打鼾可通过保持两个外侧端口开放进行修复控制,防止外侧端口壁的软组织与咽瓣振动。
