This procedure removes the submandibular (or submaxillary) salivary gland, located beneath the lower jaw. It may be performed if there are chronic infections, stones blocking the duct, or tumors (most of which are benign but occasionally malignant).

The surgery is done under general anesthesia through an incision under the jawline. The gland is carefully removed while protecting nearby nerves that control tongue movement and feeling. A drain may be placed temporarily to prevent fluid buildup. Recovery includes a few days of swelling, mild pain, and possible temporary numbness under the chin or tongue. Most people return to normal activities within a week. Follow-up includes monitoring the incision and reviewing pathology if a tumor is involved. Long-term issues are rare, and most patients experience relief from their symptoms.
