Background. Surgery for recurrent parotid pleomorphic adenoma is a challenging problem. Methods. One hundred eight patients who underwent 134 reoperations for recurrent parotid pleomorphic adenoma (follow-up, 22 years) were evaluated for histopathologic features and risk factors for recurrence. Results. The number of reoperations for tumor recurrence ranged from 1 to 10. Twenty-seven patients(25%) developed permanent facial nerve weakness. The risks for clinically evident rerecurrence after 1, 5, and 15 years were 16%, 42%, and 75%, respectively. Female sex, young age at initial treatment, and enucleation instead of paroticlectomy for treatment of the first recurrence were significant risk factors for rerecurrence. The mean number of recurrent tumor nodules was 26. Conclusions. Surgery for recurrent parotid pleomorphic adenoma has a high rate of facial nerve morbidity. The chance of rerecurrence is high. Extended paroticlectomy seems to be the best approach for the reoperation to reduce the risk of rerecurrence. (c) 2007 Wiley Periodicals, Inc.
