颞骨骨折和听骨链损伤

Temproal bone fracture and ossicular chain injuries

耳聋是颞骨骨折后一种较常见的并发症,可以是一过性的、永久性的,也可能是进展性的。耳聋的分型可以是传导性、感音神经性或混合性。感音神经性聋的原因有迷路震荡、出血、骨折,外淋巴瘘,脑干损伤[1],传导性聋中比较常见的原因是鼓膜穿孔,血鼓室及听骨链损伤。本文查询了颞骨骨折后听骨链损伤的相关文献,对流行病学,发病机制,手术时机,手术方式等方面进行了综述。

Deafness following temproal bone fracture are common complications, maybe transient, permanent, or progressvie. Classification of deafness can be a conductive deafness, sensorineural deafness or mixed deafness. The reasons of sensorineural deafness are labyrinth shock, hemorrhage, fracture, perilymph fistula, brain stem injury. The reasons of conductive deafness are tympanic membrane perforation, haemotympanum and ossicular chain injury. This paper queries the relevant literature, the ossicular chain injuries after fracture of temporal bone on epidemiology, pathogenesis, operation time, operation methods were reviewed.
