Benign osteitis of the external auditory canal is a distinct clinical entity characterized by localized ulceration in the skin of the floor of the bony external auditory meatus with underlying osteitis and sequestration of the underlying tympanic bone. Consideration of clinical and pathological data suggests that continued self-inflicted minor trauma is an etiological factor in at least some cases. The purpose of this paper is to review benign osteitis of the external auditory canal, presenting further clinical documentation and to offer etiological suggestions based upon clinical, pathological and experimental observations. The benign nature of this condition is emphasized.
外耳道良性骨炎是一种独特的临床病症，其特征为骨性外耳道底部皮肤出现局部溃疡，并伴有下方骨质炎以及下方鼓骨的骨质坏死。对临床和病理数据的考量表明，至少在某些病例中，持续的自我造成的轻微创伤是一个病因。本文的目的是对外耳道良性骨炎进行综述，提供更多临床资料，并基于临床、病理和实验观察结果提出病因学建议。强调了这种病症的良性本质。
