“…The head and neck specific questionnaire EORTC QLQ-H&N35 consists of seven multiple-item scales and six symptom items with a total of 35 questions that assess pain, swallowing, senses (taste and smell), speech, social eating, social contact, sexuality, teeth problems, trismus, dry mouth, sticky saliva, cough and feeling ill. A high score for a symptom scale indicates a higher level of symptoms or problems. This questionnaire has been used in several studies including Bjordal et al (26), Aplak et al (40), Boscolo-Rizzo et al (41), Nalbadian et al (42), and Baharvand et al (25). According to the results of this study, the mean score of QoL after being affected by radiationinduced gustatory disturbance was 20 points more than the mean score of QoL before radiation therapy, which is an indicative of a poorer QoL after being affected by radiationinduced gustatory disturbance.…”
