Objective: This study aims to determine clinical outcomes following lateral temporal bone resection (LTBR) for squamous cell carcinoma.

Subjects and Methods: A retrospective review of medical records was performed on patients receiving LTBR for squamous cell carcinoma between 1990 and 2011 at a single tertiary referral center.

Results: The records of 36 patients were analyzed with the mean age at the time of surgery being 64.1 years. Overall survival was 93%, 83%, 77%, 77%, and 58% at 1, 2, 5, 10, and 15 years after surgery, respectively. Disease free survival was 63%, 50%, 43%, 43%, and 43% at 1, 2, 5,10, and 15 years after surgery, respectively. Achieving negative margins improved overall survival, disease-free survival, and local control. Additional subgroup analyses are also presented.

Conclusions: In patients with squamous cell carcinoma of the ear and temporal bone, surgical excision, including lateral temporal bone resection, is an effective management strategy. Complete removal of disease may improve outcomes. When present, recurrences occur within a few years of surgery, and are likely to be local.
