听器官先天发育缺陷的发生率在3.1～20/1000之间,其修复问题有巨大的社会意义。外及中耳发育缺陷的程度,耳聋程度和性质,直接关系到手术的功能效果。本文报告103例先天性听器官发育缺陷病例,其中43例无手术适应症(骨导听力下降45～50dB,岩部发育不良,咽鼓管缺如等),其余60例,外耳畸形用旋转皮瓣加管状皮瓣修复并重建骨性外耳道、恢复中耳传声系统,用颞肌筋膜重建鼓膜。手术效果:44例近期听力效果满意,听力增进10～40dB。经3～5年后3例听阈提高10～15dB,1例回复到术前水平,此外有8例在术后1年
Listen to the incidence of organ development defects in the 3.1 ~ 20/1000 between the repair problem has a huge social significance. External and middle ear development defects, the degree and nature of deafness, is directly related to the functional effect of surgery. This article reports 103 cases of congenital defects in the development of auditory organs, of which 43 cases without surgical indications (bone conduction hearing loss 45 ~ 50dB, dysplastic rock, eustachian tube absence, etc.), the remaining 60 cases of external ear deformity with rotating flap With tubular flap repair and reconstruction of the bony external auditory canal, recovery of the middle ear sound system, with temporal fascia reconstruction of the tympanic membrane. Surgical effect: 44 cases of recent hearing satisfaction, hearing enhancement 10 ~ 40dB. After 3 to 5 years 3 cases hearing threshold increased 10 ~ 15dB, 1 case returned to the preoperative level, in addition to 8 cases in 1 year after surgery
