30例以前未手术的粘膜下腭裂，隐匿性粘膜下腭裂阶段，和单侧先天性腭帆提肌麻痹的患者进行了检查。所有患者均接受了全面的耳镜，内窥镜，听力学和鼓室测试评估。腭帆提肌异常、咽鼓管口异常与中耳通气和障碍之间存在相关性。23例中耳通气正常。 在3名患者中发现了中耳负压，因此在并存的鼻窦炎治疗后恢复正常。仅4例发现慢性中耳炎，其中1例经鼻窦炎治疗后中耳积液消失。我们的结论是，腭帆提肌在咽鼓管开放机制中没有明显的作用，只能被认为是一种咽瓣膜肌。
Thirty previously unoperated patients with submucous cleft palate, occult submucous cleft phase, and unilateral congenital paralysis of the levator veli palatini muscle were examined. All patients were subjected to a comprehensive otoscopic, endoscopic, audiologic, and tympanometric evaluation. A correlation was made between levator veli palatini muscle anomalies, eustachian tube orifice anomalies, and middle ear ventilation and disorders. Normal middle ear ventilation was found in 23 patients. Negative middle ear pressure that consequently normalized following treatment of coexisting sinusitis was found in 3 patients. Only in 4 patients was chronic middle ear disease found. In one of them, middle ear effusion disappeared following successful treatment of sinusitis. Our conclusion is that the levator veli palatini muscle has no significant function in the opening mechanism of the eustachian tube and must be considered as a velopharyngeal valve muscle only.
