Schwannoma of the external auditory canal is a rare finding. There are reports of extension of intracranial schwannomas laterally to fill the middle ear and meatus, but in reviewing the English literature, we have found only one report of a primary external canal schwannoma. Three have been reported in the world literature. Such a tumor is described in a 45 year old man, which completely filled the external auditory canal. Total excision was achieved with care to preserve canal skin, to prevent stenosis, and to aid in healing.
外耳道神经鞘瘤是一种罕见的病症。有关于颅内神经鞘瘤向外侧延伸至充满中耳和外耳道的报道,但在查阅英文文献时,我们仅发现一例原发性外耳道神经鞘瘤的报告。世界文献中报道过三例。本文描述了一名45岁男性患者的此类肿瘤,该肿瘤完全充满外耳道。手术小心地完整切除肿瘤,同时注意保留外耳道皮肤,防止狭窄,并促进愈合。
