“…Some authors consider the SAN as the only motor supply [13,14], while others maintain that this nerve and the cervical plexus branches provide a variable contribution to upper trapezius motor innervation [15][16][17]. Recent anatomical studies by Kierner et al [18][19][20] have clarified the relationship between the SAN and the cervical plexus.…”

Subclinical spinal accessory nerve impairment can be observed even after selective neck dissections (levels II-IV) due to routine clearance of sublevel IIB. Further studies should be performed to select patients in whom this sublevel could be left undissected without impairing oncologic radicality and to demonstrate if such a policy leads to better functional results. Early diagnosis of shoulder syndrome by questionnaires and clinical tests is recommended to appropriately plan physical therapy. Spinal accessory nerve repair is advocated to reduce the prevalence of shoulder syndrome after radical neck dissection. More data are needed to assess the superiority of newer techniques such as nerve transposition or bioresorbable nerve guides.

signs and symptoms were found related to SANP. A strong relationship appeared between the presence of the scapular flip sign and SANP. The suspected mechanism for the scapular flip sign is the unopposed pull of the humeral external rotators by the inactive middle and lower trapezius. Early identification of SANP can assist with the prognosis, explain persistent impairments and functional deficits, motivate appropriate diagnostic testing and interventions, and help maximize outcome. Further research to validate the scapular flip sign and establish a clinical prediction rule for the diagnosis of SANP should be performed.
