抄録

Squamous cell carcinoma (SCC) of the external auditory canal is an extremely rare lesion with an incidenceof approximately 1.4 cases per million. To date there is no accepted staging system or treatment guidelinefor SCC.<BR>A 76-year-old man had experienced an obstructive sensation of the right ear for 6 months. There was aswollen lesion from his eardrum to the deep auditory canal. The pathological diagnosis was SCC by biopsy fromthe deep extemal auditory canal. CT scan demonstrated no bony erosion or soft issue involvement, likelybecause this tumor was in the early stage (T2NOMO). This patient was treated for SCC of the extemal auditorycanal with tympanoplasty and canaloplasty. Two years post-operatively, there has been no recurrent tumoror stenosis at his extemal auditory canal. In limited lesions it may be possible to preserve the ossicles andreconstruct the conducting mechanism of the ear. However, on appraisal of this case, we must consider the indicationsand strict observation on the patient postoperatively.
