Abstract
Our goal was to evaluate the shoulder dysfunction after radiotherapy in surgically and nonsurgically treated necks.A prospective pair matched design was performed. A total of 96 patients from 3 groups were enrolled in the study. The patients were asked to complete the shoulder domain section of the University of Washington Quality of Life questionnaire on 2 occasions: preoperatively and 12 months postoperatively.None of the patients had a shoulder impairment before the operation. At the follow-up session, 4 patients who had received radiotherapy only reported mild shoulder dysfunction, the mean score was 96.3, the difference was significant compared with the preoperative score (P = 0.046). For patients who had received neck dissection, 7 patients reported that the impaired shoulder function caused them to change their work and 14 patients reported that their shoulder function was affected a little; the mean score was 71.6. For patients who had received both neck dissection and postoperative radiotherapy, 9 patients reported that they had changed their work due to shoulder dysfunction and 16 patients reported mild shoulder impairment; the mean score was 65.3 and the difference was not significant (P = 0.304).Radiotherapy does not increase shoulder dysfunction in surgically treated necks, but it could induce shoulder impairment in nonsurgically treated necks.
