由于改善听力手术的进展,听骨X线诊断已引起不少耳科和放射科医生重视,因为听骨状态决定手术形式的选择。本文根据我们工作中点滴经验介绍听骨X线诊断中一些问题。一、听骨解剖:鼓室是个圆筒形含气空腔,其高为12～15毫米,宽6～9毫米。三块听骨位于鼓室内,锤骨、砧骨和镫骨互成关节,在声音传导过程中起杠杆作用。根据我们对听骨标本的测量;锤骨在三块听骨中最大,分头、颈、柄 Due to the improvement of the progress of hearing surgery, ossicular X-ray diagnosis has caused many ear and radiologists attention, because the ossification determines the surgical form of choice. This article based on our work experience drip X-ray diagnosis of some problems. First, the auditory bone anatomy: tympanic cavity is a gas cylinder, which is 12 to 15 mm high and 6 to 9 mm wide. The three ossicles are located in the tympanic cavity, and the malleus, incus and tarsal joints form an articulation that acts as a lever in the process of sound conduction. According to our measurement of the ossicles, the malleus is the largest of the three ossicles, divided, necked, and stalked
