title: Impact of conventional radiotherapy on health-related quality of life and critical functions of the head and neck.
abstract: OBJECTIVE
  Head-and-neck radiotherapy is associated with significant morbidities. Our purpose was to document impact of morbidities by use of multiple objective measures and health-related quality of life (HR-QOL).
  
  
  METHODS
  Ten head-and-neck cancer patients were evaluated before receiving conventional head-and-neck radiotherapy and at 1 month and 6 months after treatment. We evaluated weight, saliva production, diet, swallow function, auditory function, and HR-QOL.
  
  
  RESULTS
  After radiotherapy, weight was reduced in 89% of subjects. Salivary function was significantly reduced and did not resolve by 6 months. Diet impairment and abnormalities in swallowing function persisted at 6 months. Perception of physical functioning was reduced after treatment, and swallowing, coughing, and dry-mouth symptoms increased. Very few changes were observed in auditory function.
  
  
  CONCLUSIONS
  Conventional head-and-neck radiotherapy is associated with substantial functional deficits and diminished HR-QOL. Deficits reported here can serve as a baseline for comparison with results derived from new radiotherapy-treatment techniques.
