[Treatment of recurrence of pleomorphic adenomas of the parotid gland].

This is a retrospective study of 10 patients who underwent surgery for a first or multiple recurrence of pleomorphic adenoma (P.A.). Recurrence may come more than 10 years after an initial episode. During initial surgery, the risk of recurrence is related to pre-operative dissemination and to failure to identify tumoral prolongations in the parotid gland. Recurrence is generally multifocal. In 2 cases, carcinoma developed in association with P.A. Treatment of benign recurrence is surgical: it consists of totalizing the previous parotidectomy. If the previous parotidectomy has been total, tumorectomy is carried out. In all cases, surgery preserves the facial nerve trunk.
