      Abstract

      The most widely accepted treatment for neoplasms of the submandibular gland usually involves excision of the entire gland. Our aim was to establish a gland-preserving operation for benign tumours of the submandibular gland and evaluate its efficacy. We treated 40 patients from January 2007 to December 2008 with benign submandibular gland tumours who were listed to have an operation that either preserved the gland or sacrificed it. Duration of operation, extent of injury to the nerve, postoperative function of the gland, aesthetic appearance, and recurrence were assessed. We found no significant difference in baseline characteristics among the 20 patients in each group (19 men; 21 women, mean (SD) age of 34 (33.8 ± 5.72) years. The extent of injury to the lingual nerve and submandibular branch, together with deformities of the facial contour, were significantly less in the group in which the gland was preserved. Postoperative salivary production and overall patients’ satisfaction were also better in that group. There was no recurrence in either group during the follow up period of 38 months–5 years. The gland-preserving procedure has advantages over the typical approach in which the gland is sacrificed. There is less risk of injury to the nerve, less deformity of the facial contour, better preservation of function, and patients are more satisfied. The gland-preserving technique should therefore be the first choice for management of benign submandibular tumours.
