Assessing Shoulder Dysfunction Following Neck Dissection for Treating Squamous Cell Carcinoma of the Oral Cavity

Aim: The objective of this study is to evaluate the impact of neck dissection on shoulder dysfunction, encompassing pain and disability, over a six-month follow-up period in individuals who have undergone surgery for squamous cell carcinoma of the oral cavity. Objectives: This observational study was conducted to assess the evolution of the degree and extent of shoulder pain and shoulder disability during a six-month period following neck dissection. Materials and methods: All patients who had undergone neck dissection as part of their treatment for squamous cell carcinoma of the oral cavity and had provided written consent to participate in the study were subjected to an evaluation of shoulder dysfunction using the SPADI index. The SPADI questionnaire was administered, and corresponding scores were assigned to each patient based on their responses. Result: In summary, the manipulation of cranial nerve XI during neck dissection indeed leads to shoulder pain, decreased shoulder range of motion, reduced strength, and limitations in shoulder-related activities. Furthermore, the degree of manipulation of cranial nerve XI has a notable impact on these outcomes.
