OBJECTIVES: Temporal bone squamous cell carcinoma (TSCC) is a rare malignancy. Due to its low incidence rate, studies involving TSCC treatment are limited. The aim of this study is to define the prognostic factors of surgery for TSCC by evaluating our clinical experience. METHODS: We reviewed the clinical charts of patients presenting at the University of Tokyo Hospital between 2001 and 2014 and identified 33 patients with TSCC who had been treated with surgery as initial curative treatment. RESULTS: Lateral and subtotal temporal bone resections were performed in 17 and 16 patients, respectively. The 5-year disease-specific and overall survival rate were 71 and 62%, respectively. The significant poor prognostic factors were pathological T4 (P = 0.03), dural invasion (P = 0.008), temporomandibular joint invasion (P = 0.04), and a positive surgical margin (P = 0.009). CONCLUSION: We demonstrated that the outcome of curative surgery for TSCC as initial treatment was favorable. However, because of the difficulty to ensure an adequate or clear surgical margin due to anatomical complexity, the surgical indication for T4 TSCC with temporomandibular joint invasion should be reconsidered.
