Abstract
PurposeIn this study we review our institution's experience and outcomes with temporal bone resection and parotidectomy in the treatment of advanced parotid malignancies. MethodsPatients undergoing lateral temporal bone resection and parotidectomy from 2007–2013 were identified in the EPIC electronic medical record. Primary tumor location, staging, surgical procedure, and patient demographic and outcome data were collected retrospectively. ResultsFifteen patients underwent combined temporal bone resection and parotidectomy for parotid malignancy. Carcinoma ex-pleomorphic and squamous cell carcinoma were the most common pathologies. Two year disease free survival was 40%. Distant metastases were the most common site of disease recurrence. Only nodal disease was predictive of reduced disease free survival, though pre-operative facial paralysis showed a trend towards significance. Margin status and operating for recurrent tumor did not influence outcome in our series. ConclusionLocal and regional tumor controls are attainable with combined skull base approaches to advanced parotid malignancies. Unfortunately these cases have a high rate of distant recurrence despite negative margins and local control.
