目的观察腭裂术后患者软腭运动功能对改善中耳功能和减少听力损害的作用.方法对2011年7月至2012年9月北京大学口腔医学院·口腔医院唇腭裂治疗中心接受治疗的64例非综合征型腭裂术后患者进行纯音听阈测试,并对腭裂术后头颅侧位X线片(包括静止位、发“i”音位)行头影测量.记录测量结果并对其听力阈值与软腭抬高角度和腭咽闭合率分别行相关性分析.结果 64例患者软腭抬高角度平均值为(29.31±18.36)°,腭咽闭合率为(0.54±0.13)％,听力阈值为(14.56±8.79) dB.相关分析显示腭裂术后听力阈值与软腭抬高角度间的相关关系为低度负相关(r=-0.339,P＜0.01).随软腭抬高角度增大、听力阈值减小,腭裂术后听力阈值与腭咽闭合率之间的相关系数r=-0.277,P＜0.01,两者的相关关系为低度负相关.随腭咽闭合率增大、听力阈值减小,腭裂术后听力阈值与软腭抬高角度和腭咽闭合率均存在相关性,但与前者相关程度更高.结论腭裂术后患者的软腭运动功能与腭咽闭合状况均影响患者听力,两者相比前者对听力影响更大.

Objective To explore the relationship between hearing level and soft palate movement after palatoplasty and to verify the importance of recovery of soft palate movement function for improving the middle ear function as well as reducing the hearing loss.Methods A total of 64 non-syndromic cleft palate patients were selected and the lateral cephalometric radiographs were taken.The patients hearing level was evaluated by the pure tone hearing threshold examination.This study also analyzed the correlation between hearing threshold of the patients after palatoplasty and the soft palate elevation angle and velopharyngeal rate respectively.Results Kendall correlation analysis revealed that the correlation coefficient between hearing threshold and the soft palate elevation angle after palatoplasty was-0.339 (r=-0.339,P＜0.01).The correlation showed a negative correlation.The hearing threshold decreased as the soft palate elevation angle increased.After palatoplasty,the correlation coefficient between the hearing threshold and the rate of velopharyngeal closure was-0.277 (r=-0.277,P＜0.01).The correlation showed a negative correlation.While,The hearing threshold decreased with the increase of velopharyngeal closure rate.The hearing threshold was correlated with soft palate elevation angle and velpharyngeal closure rate.Conclusions The movement of soft palate and velopharyngeal closure function after palatoplasty both have impact on patient hearing level.In terms of the influence level,the movement of soft palate has a higher level of impact on patient hearing level than velopharygeal closure function.
