从病因学来看,由于腭帆张肌的中央部控制咽鼓管的开放,腭帆提肌有辅助腭帆张肌的作用。腭裂患者因耳咽管功能异常而引起中耳疾病,在软腭裂儿童中中耳疾病发病率为96％。但在前部腭裂达门齿孔的儿童中仅占22％。腭裂小儿咽鼓管阻塞较异常开放更容易引起耳部疾病,一旦中耳腔不能维持正常压力,可出现鼓膜内陷、渗液及负压增加,Bluestene等对修
From the etiology point of view, due to the central part of the palatal fan to control the opening of the eustachian tube, the palatal sail levator ani assist the role of the palatal fan. Patients with cleft palate have middle ear disease due to dysfunctional eustachian tubes and a middle ear disease rate of 96% in children with cleft palate. However, only 22% of children with anterior cleft palate reached the perforation. Cleft palate Children eustachian tube obstruction more open than the more likely to cause ear disease, once the middle ear cavity can not maintain normal pressure, there may be tympanic membrane retraction, exudate and negative pressure increase, Bluestene and other repair
