- Abstract
- Malignant tumors of the external auditory canal are rare diseases, pathologically, squamous cell carcinoma (SCC) is the most common, and adenoid cystic carcinoma (ACC), basal cell carcinoma (BCC), and melanoma are reported. The overall prognosis varies slightly depending on the pathologic tissue type, but it greatly depends on the extent of invasion of the primary lesion before surgery. In order to determine the exact pre-surgical diagnosis and the extent of the tumor, it is necessary to rely on radiological diagnosis rather than evaluating the extent of the lesion only by history taking and physical examination. As a standard for surgical treatment, en bloc resection of tumors with sufficient safety margin of tumor is the principle. Through partial resection of the temporal bone, the function of the cochlear and facial nerves can be preserved along with the complete removal of the tumor, and if the annulus is preserved, it can be restored to hearing. However, insufficient surgery can cause treatment failure and lead to a wider recurrence, making future treatment more difficult. In this case, we would like to discuss the evaluation and surgical treatment methods in patients with small SCC limited to the external auditory canal as an 84-year-old patient.
