Surgical management of benign tumors of the submandibular gland: a follow-up study

Abstract

Purpose: This retrospective study evaluated data pertaining to history, symptoms, diagnosis, and mode of therapy of patients treated for benign tumors of the submandibular gland.

Patients and methods: The records of 38 patients were reviewed. The patients were divided into three groups: pleomorphic adenoma (first operation), pleomorphic adenoma (second operation for recurrence), and other tumors. Follow-up was done by questionnaires sent to the patient and referring doctor.

Results: The vast majority of patients treated (92%) had had either a first or second operation for pleomorphic adenoma. Follow-up revealed that recurrence did not develop in the group of patients with primary surgery. However, one patient undergoing surgery for recurrent pleomorphic adenoma developed two recurrences. Two patients suffered from slight weakness of the lower lip.

Conclusion: Tumor recurrence was found only in the cases of second operation after previous surgery for pleomorphic adenoma. Therefore, the first operation should extirpate the entire gland to minimize the risk of recurrence.
