causes marked functional shoulder disability due to sacrifice of spinal accessory nerve. Classical neck dissection causes shoulder syndrome in up to

60 % of the cases. To the best of our knowledge, there is no data so far which compares various objective shoulder assessments following the radical

neck dissection. Hence this study was conducted.

Material and methods: This prospective descriptive study was conducted from May 2016 to November 2017 in 20 patients with biopsy proven

head and neck malignancy. The exclusion criteria were 1: Preoperative chemotherapy or radiotherapy, 2: Recurrent cases 3: History of adhesive

capsulitis or trauma or surgical intervention to the shoulder. DASH score, ASES score and SST score were obtained preoperatively and one month

following radical neck dissection.

Results: 15 were Male (75%) and 5 were females (25%).The average age of the patients was 59.15 (48–71 yrs) range. The average DASH scores in

the post–operative patients was 42.5 and the average ASES score was 47.65. The average SST was 5.45.

Conclusion: Shoulder dysfunction is caused by trapezius deficit due to various degree of dysfunction of spinal accessory nerve. It is regrettable that

a procedure designed to save life affects the quality of life as evidenced by postoperative worsening in various shoulder scores. Owing to

hampering effects following radical neck dissection has rightfully directed the emergence of nerve sparing procedures such as selective and super

selective neck dissection.
