Submandibular gland excision: short- and long-term complications.

During a 10-year period, 159 benign submandibular gland excisions were performed in 157 patients. 86 of the patients were available for follow-up evaluation. Both short- and long-term complications were listed. Neurapraxia to the mandibular branch of the facial nerve was frequent after the operation, but restoration of function was seen in 92.3%. Scar problems, sensation changes, reduced salivation and taste perception were noticed by the patients in several cases, but rarely caused dissatisfaction. 18.2% of the patients in the salivary stone group had residual stones in Wharton's duct after the operation. The indication for removal of both glands should be carefully considered because of development of xerostomia.
