Frequency and outcomes of submandibular gland obstruction following resection of squamous cell carcinomas in the vicinity of the submandibular duct

IntroductionThe aim of this study was to report rates, associated factors and outcomes of submandibular gland obstruction following surgery for squamous cell carcinoma in the anterior floor of the mouth (FOM) or ventral tongue without a neck dissection where resection has involved (or has been in very close proximity to) the submandibular duct. MethodsA retrospective case note review was carried out for the period January 2007 to December 2011. Only patients who received primary local surgical resection for squamous cell carcinoma of the anterior FOM or ventral tongue were included. ResultsFifty-two patients were analysed. Fifteen (29%) developed submandibular gland symptoms following surgery. Symptoms resolved spontaneously for 14 (93%) and 1 patient required the submandibular duct to be repositioned. Comparatively, 2 patients (13%) developed symptoms when the duct was repositioned during primary surgery. No patients had their submandibular gland removed. ConclusionsResection of small tumours associated ...
