耳科医生常遇到中耳充气不良鼓膜萎陷、局部或全部与鼓岬粘连的病人。这种病好发于唇裂的儿童,成人则见于咽鼓管功能不良者。菲薄的鼓膜可包绕听骨链妨碍其活动,甚至导致砧镫关节坏死。鼓膜与鼓岬粘连较重者安置中耳通气管十分困难。本文介绍一种方法,作者多年体验效果很好。方法:儿童全麻,成人局麻。用皮试针管接一30号长针头,在鼓膜前上象限近鼓环处穿刺,缓慢注入生理盐水,可见凹陷的鼓膜逐步展开并与鼓岬脱离。这样就可在近鼓环处选择最牢
An otologist often encounters a patient with poorly inflated tympanic membrane in the middle ear, with partial or complete adhesions to the promontory. This disease occurs in children with cleft lip, adults are found in eustachian tube dysfunction. Filthy tympanic membrane can surround the ossicular chain impeding its activity, and even lead to anvil joint necrosis. Eardrum and drum promontory adhesions heavier placement of the middle ear ventilation tube is very difficult. This article describes a method that the author has worked well for years. Methods: Child general anesthesia, adult local anesthesia. Needle with a skin test needle connected to a long needle 30, in the tympanic membrane near the upper quadrant of the ring puncture, slow infusion of saline, showing the hollow erection of the membrane and gradually expand and promulgated Cape promontory. This will select the strongest ring near the drum
