Imai T, Sato Y, Abe J, et al. - Researchers performed the evaluation of the shoulder-specific quality-of-life questionnaire and active shoulder abduction to evaluate shoulder function after neck dissection. A prospective cohort was conducted including a total of 66 patients (85 neck dissection sides) who had undergone neck dissection between December 2015 and July 2017 at a single institution. They analyzed the active shoulder abduction angles of the affected side and the patient-reported shoulder-specific quality-of-life recovery score of the Western Ontario Rotator Cuff questionnaire at 1, 3, 6, 9, and 12 months postoperatively. Additionally, they evaluated the correlation between these outcomes and risk factors for shoulder impairment. After neck dissection, satisfactory functional and qualitative recovery of shoulder function was achieved at 6 months. In the early postoperative period, postoperative radiotherapy was a prognosticator of poor shoulder function; both level V dissection and head and neck irradiation were predictors of poor shoulder function at 6 and 9 months after neck dissection.
