通过对２５例腭裂患者进行纯音测听、鼓室压图、乳突Ｘ线和临床体征等观察，并进行了分析，结果显示：３８％患者为轻度听力减退（听阈２５～４０ｄＢ），８％患者为中度听力减退（听阈４１～７０ｄＢ），鼓室图中Ｂ型曲线占３２％，Ｃ型曲线占１２％；三种类型腭裂的听力和鼓室压图结果并无显著性差异（Ｐ＞０．０５），乳突Ｘ线表现除１例双耳呈气化型乳突和２例４耳乳突呈硬化型乳突外，其余均为板障型乳突。认为大部分腭裂患者均有中耳功能障碍，主要是通过影响咽鼓管所致。
The results of pure tone audiometry, tympanogram, mammogram and clinical signs in 25 patients with cleft palate revealed that 38% of patients had mild hearing loss (25-40 dB at hearing threshold), 8% Patients with moderate hearing loss (hearing threshold 41 ~ 70dB), tympanogram in the B-type curve accounted for 32%, C-type curve accounted for 12%; three types of cleft palate hearing and tympanogram did not show significant difference (P> 0 .05), mastoid X-ray findings in addition to a case of both ears gasification type mastoid and 2 cases of 4 ear mastoid scleroderma, the rest are baffled papillae. That most patients with cleft palate have middle ear dysfunction, mainly caused by affecting the Eustachian tube.
