Material and Method: The authors retrospectively reviewed the patients treated for primary carcinoma of temporal bone in Otolaryngology Head and Neck Surgery department, at Songklanagarind Hospital between 2002 and 2013. Thirty-two patients, including 10 cancer of pinna and 22 carcinoma of the External Auditory Canal (EAC), were included in this study. The treatment modality was lateral temporal bone resection and postoperative radiotherapy and palliative radiotherapy for advanced stage tumors (T4). Twelve patients were excluded due to difference in modality. Twenty patients remained in the study.

Results: Twenty patients had carcinoma of EAC, early stage (T1, T2) 36.4% and late stage (T3, T4) 63.6%. The overall survival of this group was 46.9%. The median survival period was 22 months (0.286-0.769, 95% CI).

Conclusion: The complete resection is the treatment of choice in primary cancer of temporal bone. Postoperative radiotherapy for a microscopic residual tumor is highly recommended. The most important thing is early diagnosis.
