External ear squeeze 外耳道擠壓症
( Tintinalli's Emergency Medicine ) External ear squeeze 外耳道擠壓症 外耳道如果因耳垢或耳塞造成阻塞, 無法平衡耳膜及外耳道壓力, 導致耳膜向外突出, 稱為外耳道擠壓症. 症狀包括疼痛及耳膜出血. If the external canal is occluded by cerumen or an ear plug, the inability to equalize pressure between the external canal and the tympanic membrane causes the bending of the tympanic membrane outward, producing an injury called “external ear squeeze” that produces pain and tympanic membrane hemorrhage.
