软带骨桥在双侧小耳畸形患者中的应用

Contact mini in patients with bilateral congenital microtia

目的探讨佩戴软带骨桥在双侧小耳畸形患者中的临床应用效果。方法选取36例双侧小耳畸形患者,每例患者分别佩戴软带骨桥与软带骨锚式助听器(BAHA),佩戴前后分别测量声场纯音测听,并随访观察佩戴软带骨桥后患者的日常交流及对声音的反应情况。结果 36例双侧小耳畸形患者佩戴软带骨桥后行声场纯音测听结果显示,平均气导听力提高38.8 dB,佩戴软带BAHA后行声场纯音测听结果显示,平均气导听力提高34.5 dB,二者比较差异无统计学意义(P>0.05),患者日常生活交流情况明显改善。结论对于先天性双侧小耳畸形患者,佩戴软带骨桥后,听力提高显著,效果良好。

Objective To evaluate the clinical applications of Contact Mini in patients with bilateral congenital microtia. Methods Contact Mini and bone anchoring hearing aids (BAHA) worn by 36 patients with bilateral congenital microtia were compared in terms of pure tone hearing sound field audiometry findings, before and after wearing.The patients were followed up to observe daily communication and the response to sound after wearing Contact Mini. Results Hearing improved by an average of 38.8 dB and 34.5 dB after Contact Mini and BAHA usage, respectively. Although there was no statistically significant difference between the two groups (P〉0.05), the daily communication was significantly improved. Conclusions Contact Mini device can effectively improve audiometry with a satisfactory effect in bilateral congenital microtia patients.
