Abstract
Ten patients (9 females and 1 male) with recurrent pleomorphic adenomas of the parotid gland were investigated clinically. Two of them were treated primarily in our hospital, 6 were treated by other otolaryngologists and 2 were treated by general surgeons. The cause of recurrence depends on the tumor type, their capsule and initial treatment. Partial parotidectomy is the first procedure that should be performed in these cases.Surgery was performed in all 10 patients: total parotidectomy in 1, partial parotidectomy in 7, and tumor enucleation in 2. The myxoid type and multiple tumor were the most common recurrent tumors. Tumors recurred again in 3 of our cases that had not undergone resection of their incision scars. Complete resection of the tumor and the surrounding scar is essential in the treatment of a recurrent tumor. Although preservation of the facial nerve is important, it is sometimes necessary to cut the nerve. These tumors can become malignant, so the management of each recurrent tumor should be monitored carefully.
