腭裂与中耳功能障碍的相关性

目的:探讨腭裂手术对患者中耳功能的影响,为早期改善患者中耳功能提供依据。方法:对112例(224耳)腭裂患者进行年龄分组,采用声导抗、纯音测听或听性脑干反应检查。65例腭裂伴分泌性中耳炎患者在作腭裂修复术的同时,行鼓室置管术,术前术后作听力学检测,术前对鼓室分泌物作细菌培养。结果:腭裂患者常伴有不同程度的中耳功能障碍,腭裂修复术能明显改善患者中耳功能(P<0.05)。鼓室分泌物G+、G-细菌培养阳性率为22.86%、23.53%,且多为低毒性条件致病菌。结论:腭裂患者常有中耳功能障碍,应重视其早期预防与治疗,早期修复腭裂有助于咽鼓管功能恢复。

Relationship between cleft palate and dysfunction of the middle ear

Objective: To explore the effect of palate repair on the function of middle ear,and provide evidence for early treatment of dysfunction of middle ear.Methods: A total of 112 cleft palate patients(224 ears) were investigated by pure tone audiometry,acoustic immiscible audiometry and auditory brainstem response.Sixty-five cleft palate patients with secretory otitis media underwent palatoplasty and myringotomy with tube insertion.The organism of tympanic secretion was cultivated before operation.Results: Patients with cleft palate had dysfunction of middle ear in different degrees.The middle ear function of cleft palate patients was improved obviously by palate repair surgery(P<(0.05).) The G~+ and G~-positivity rates of organism culture of tympanic secretion were 23.08% and(24.62%) respectively,and most organisms were low poisonous and conditionally infective.Conclusions: The functional impairment of middle ears often occurres in the cleft palate patients,and measures should be taken for prevention and treatment of diseases for cleft palate patients.Early cleft palate repair facilitates the recovery of otosalpinx function and decreases the hearing loss.
