Different pathologies of the submandibular gland are an indication of submandibular gland excision-ranging from inflammatory causes and sialolithiasis to malignant tumors. The purpose of this study was to get an overview of the different indications for submandibular gland excision. The main goal of this study was to evaluate the different indications for submandibular gland excision during a 20-year period. In addition, epidemiological information and therapy concepts were investigated with a special focus on Tumor Lymph nodes Metastasis (TNM) classification and recurrence rate. Procedures during which the submandibular gland was removed while not being the primary cause for surgery (eg, neck dissection in Level Ib) were not included. During the period of observation, 359 submandibular gland excisions were performed. The most common cause for submandibular gland excision was sialolithiasis (n = 129) with intraparenchymal stone localization. Up next were inflammatory causes (n = 115) in particular chronic submandibular sialadenitis followed by only a few cases of Sjögren's syndrome, sarcoidosis, and tuberculosis. In 115 cases, surgery was performed for tumors of the submandibular gland, with 88 of them being benign and 27 malignant. Malignancies were then divided into lymphomas (n = 9) and primary salivary gland malignancies (n = 18). This retrospective study of a large cohort of patients displays a representative overview of the indications for submandibular gland excision. Sialolithiasis was the most common underlying cause of gland excision. The malignancy rate in our cohort was lower than described in the literature.
