Outcomes of submandibular duct relocation: a 15-year experience.

Drooling is common in patients with neurological disability and a major factor affecting quality of life. Management of this problem is best carried out by a team approach using surgical and non-surgical methods. Submandibular duct relocation is a commonly performed procedure with low complication rate. This procedure has been carried out in 56 patients over the last 14 years at the Belfast City Hospital by the senior author. All the patients underwent physiotherapy for six months before they were selected for surgery. All the patients were over five years of age and most had severe neurological impairment. For the purposes of this study, all the patients were followed by a questionnaire regarding symptomatic improvement, parent satisfaction and complication rate. All case notes were also reviewed retrospectively. Parental satisfaction was high and drooling was significantly reduced in 49 cases. The main complication was ranula formation seen in five cases. The most significant area of parental concern was post-operative pain. It is important to counsel the parents regarding the post-operative pain relief as well as failure rate of the procedure. It can be concluded that this procedure is a safe and highly successful procedure, which significantly improves the quality of life.
