Benign parotid tumors: a 24-year experience.

The medical records of 125 patients benign parotid neoplasms surgically treated over a 24-year period were retrospectively reviewed; 128 tumors were excised. These included 90 pleomorphic adenomas, 33 Warthin's tumors, 3 benign lymphoepitheliomas, and 2 oncocytomas. The surgical procedures consisted of 2 local excisions, 6 enucleations, 88 superficial parotidectomies, 13 subtotal parotidectomies, and 3 radical parotidectomies. The morbidity rate was 49%. There was one total permanent facial nerve paralysis (0.7%), four (3%) partial permanent facial nerve paralysis, five (5%) transient total facial nerve paralysis, and 32 (25%) partial transient facial nerve paralysis. After a median follow-up of 84 months, there was one recurrence (0.7%). A superficial parotidectomy is the minimum procedure that should be performed for the treatment of a benign parotid neoplasm.
