CORRELATION BETWEEN THE NO.OF RADIATION THERAPY SESSIONS AND MOUTH OPENING , GOTHENBURG TRISMUS QUESTIONNAIRE AND NECK DISABILITY INDEX- A CROSS SECTIONAL STUDY

Abstract

Background: Primary treatment of Head and cancer consisting of surgery along with radiation and chemotherapy results in complication such as trismus , which is dened as reduced mouth opening (<35 mm) .There is a lack in literature on the effects of radiation on patient reported outcome measures along with the maximal interincisal opening in rural population . So , this study was under taken to nd out the effects of radiation on the symptoms of trismus in patients of head and neck cancer. It is an cross sectional study conducted on 11 patients with head and neckMethod: cancer where relation between radiation therapy with MIO ( Maximal interincisal opening) , Gothenburg trismus questionnaire (GTQ) and Neck disability Index (NDI) was seen. It was found that only MIO was found to have a negative correlationResult: with no. of radiation sessions (r = - 0.822 ) but GTQ and NDI did not have relation with no. of radiation session. FromConclusion: this study we can conclude that as the no. of radiation sessions increases the mouth opening reduces in the patients of Head and neck cancer but there was no such relation found between no. of radiation sessions and trismus related questionnaire as seen in the score Gothenburg Trismus Questionnaire & Neck Disability score.
