Foreign bodies of the ear are a common finding in children. The majority of these can be removed relatively easily. We present a case which required endaural incision and widening of the external meatus before the foreign body could be successfully removed. Entrapment of the hard, oval-shaped, smooth and slippery foreign body deep to the hour-glass narrowing of the external canal, proximity of the object to the tympanic membrane and localised tissue oedema were the indications for the surgery. This case demonstrates the danger of unskillful attempts to remove aural foreign bodies.
耳部异物在儿童中很常见。其中大多数可以相对容易地取出。我们报告一例,在成功取出异物之前,需要进行耳内切口并扩大外耳道。坚硬、椭圆形、光滑且滑溜的异物被困于外耳道沙漏状狭窄深处、异物靠近鼓膜以及局部组织水肿是手术的指征。该病例表明了不熟练地尝试取出耳部异物的危险性。
