222Background: Patients, who receive radiotherapy (RT) for head and neck cancer, develop chronic functional abnormalities and reduced mouth opening-trismus, surviving with reduced quality of life (QoL). We aimed to study trismus and QoL in patients with oral cancer, who received post-operative radiotherapy or chemoradiotherapy. Methods: Patients, who receive radiotherapy (RT) for head and neck cancer, develop chronic functional abnormalities and reduced mouth opening-trismus, surviving with reduced quality of life (QoL). We aimed to study trismus and QoL in patients with oral cancer, who received post-operative radiotherapy or chemoradiotherapy. Results: Mean RT dose was 64.3 Gray. Six patients received chemoradiotherapy. Severe mucositis, pain and xerostomia were recorded in 6 and 5 patients respectively. MMO was reduced in all patients. The mean MMO (34 mm) reached the level of trismus. The total number of symptoms increased from 3.1 to 6.3 in C-30 and from 3.1 to 8.8 per patient in the H/N35. Severe fa...
