Surgery for cervical sympathetic chain schwannomas may result in postoperative Horner's syndrome. Thus, appropriate informed consent and adequate surgical experience are required to prevent any decrease in patients' quality of life (QOL) following such surgery. Here we report three cases of cervical sympathetic chain schwannomas, focusing on diagnosis and postoperative neuroparalysis. A schwannoma is suspected on pre-operative imaging when the common carotid artery (internal and external carotid artery) and internal jugular vein are located in front of or alongside the tumor, and cases in which the artery and vein are not separated are considered to be of sympathetic nerve origin. Since the origin nerve comes from the back anatomically, great care is needed during surgery. None of the patients in this study had symptoms of nerve paralysis postoperatively.
