Brief summary

Postoperative nerve palsy is a major complication following resection of neck peripheral nerve sheath tumors. This study is a retrospective cohort aimed to predict the nerve origin of neck peripheral nerve sheath tumors. Accurate preoperative identification of the nerve origin can improve surgical outcomes and patient counseling

Detailed description

Postoperative nerve palsy is a major complication following resection of neck peripheral nerve sheath tumors (PNSTs). Accurate preoperative identification of the nerve origin (NO) can improve surgical outcomes and patient counseling. This study aims to predict the NO of neck PNSTs with radiographic analysis. This study is a retrospective cohort analysis. Radiographic parameters will be reviewed and the sensitivity, specificity, accuracy of NO prediction will be evaluated.

Interventions

PROCEDUREExcision

All patients underwent surgery under general anesthesia and intraoperative neuromonitoring according to the preoperatively predicted NO. Using an anterior cervical approach, the tumor was delineated after identifying the relationships among the great vessels, nerves, and tumors. The NO was confirmed intraoperatively. Sharp dissection was performed meticulously to enucleate the tumor from the NO to preserve most nerve fibers.
