目的:分析外耳畸形与中耳畸形的关系和手术治疗的效果。方法:对52例(62耳)先天性外、中耳 畸形患者进行手术治疗,48耳采用经鼓窦乳突径路,14耳采用直入式径路。观察术中所见与外耳畸形的关系。 结果:在轻度耳廓畸形者中,鼓室及其内部结构畸形较轻;而在中、重度耳廓畸形者中,中耳畸形情况较严重。术 后3个月时平均语频听阈提高15～30dB者占53.2%;提高30dB以上者为40.3%。术后3年则分别为59.7%和 25.8%。结论:中耳畸形与耳廓畸形程度相关。治疗效果及畸形程度与是否有并发症的发生有关。
Objective: To analyze the relationship between external ear deformity and middle ear deformity and the effect of surgical treatment. Methods: Fifty-two patients (62 ears) with congenital and middle ear deformity were treated surgically. 48 ears were treated by the mastoidectomy and 14 ears were treated by straight-in approach. Observation of intraoperative findings and the relationship between the outer ear deformity. Results: In the mild auricular deformity, the tympanic cavity and the internal structure of the deformity is lighter; in moderate and severe auricle deformities, the middle ear malformations more serious. At 3 months after operation, the average speech threshold increased by 15 ~ 30dB, accounting for 53.2%; while the increase of 30dB was 40.3%. Three years after surgery were 59.7% and 25.8% respectively. Conclusion: Middle ear deformity is related to the degree of auricular deformity. The therapeutic effect and the degree of deformity are related to the occurrence of complications.
