ABSTRACT
Introduction: Malignancies of the Temporal bone are rare and aggressive type of tumours. Incidence being 1 to 6 per million population years, it accounts to less than 0.2% of all tumors of the head and neck region.
Materials and Methods: A prospective observational case series study was carried out in the Department of Otolaryngology & Head and Neck Surgery for a period of three years. All the confirmed cases of Temporal bone malignancy were included in the study.
Results: Out of the 6 cases (3 females, 3 males), 4 were Squamous Cell Carcinoma(SCC) and 2 were Mucoepidermoid Carcinoma on the basis of Histopathological Examination. 4 cases were primary in origin, 1 case of Mucoepidermoid Carcinoma developed secondary to ipsilateral Parotid malignancy. Treatment was planned according to the stage of the disease, which included – Surgery, Radiotherapy and Chemotherapy. A delay in diagnosis, masking of the disease by infection, and patient’s non-compliance to treatment affected the outcome. The patients have been regularly followed up.
Discussion: A review of literature showed that Malignancies of Temporomastoid region is a rare and aggressive entity, constituting less than 0.2% of all head and neck tumours. SCC is the most common subtype (70%), as also observed in our study (66.67%). However, Mucoepidermoid Carcinoma of Temporomastoid region is an extremely rare histological subtype.
