**6.1 Case 1**

A 67-year-old male, had been treated in 1997 for a T3N2c carcinoma of the floor of the mouth. His treatment consisted of local resection, partial mandibulectomy with free fibula reconstruction, and post-operative radiotherapy which resulted in complete remission. In 2013, 16 years after treatment, he visited the outpatient clinic with increasing swallowing difficulties, with particularly solid foods getting stuck in his throat, requiring placement of a PRG feeding tube to maintain adequate nutritional intake.
