“…It is relatively difficult to identify and remove the true tumor capsule. Previously, we reported how Narrow Band Imaging (NBI) can be used to confirm the true tumor capsule [6]. Moreover, we devised a schwannoma model and a mechanism that could not be removed unless nerve fibers that do not need to be cut if they were detached at the wrong layer [7].…”

Background: Cervical schwannoma is a relatively rare disease, and it is difficult to experience many surgical cases because it may be followed up without surgery. We examined 100 patients who underwent inter-capsular resection for cervical schwannomas at our center and classified the patients according to the nerve of origin. Methods: We retrospectively reviewed 100 patients who underwent inter-capsular resection for cervical schwannoma at our center from April 2005 to September 2019. We examined the patient's characteristics including age, sex, tumor size (maximum diameter), origin nerve, preoperative symptoms, and postoperative neurological deficits for all cases. We classified the cases according to the nerve of origin and the occurrence of postoperative neurological deficits. Results: The occurrence of postoperative neurological deficit for all cases was as follows: "none" was 73%, "temporary paralysis" was 21%, and "permanent paralysis" was 6%. In the case of vagus nerve: "none" was 65.4%, "temporary paralysis" was 23.1%, "permanent paralysis" was 11.5%. In the case of sympathetic nerve: "none" was 64.7%, "temporary paralysis" was 29.4%, "permanent paralysis" was 5.9%. In the case of brachial plexus: "none" was 87.0%, "temporary paralysis" was 13.0%, "permanent paralysis" was 0%. In the case of cervical and accessory nerves: "none" was 86.4%, "temporary paralysis" was 13.6%, "permanent paralysis" was 0%. In the case of facial nerve: "none" was 0%, "temporary paralysis" was 80.0%, "permanent paralysis" was 20%. In the case of lingual nerve: "none" was 80.0%, "temporary paralysis" was 20.0%, "permanent paralysis" was 0%. Conclusions: Inter-capsular resection is useful for the treatment of cervical schwannoma and a simple comparison is difficult, but probably with good

“…Therefore, intraneural dissection is a useful surgical technique for achieving gross total resection while preserving the capsule, including the nerves [ 4 ]. To support this method, narrow-band imaging (NBI)-guided surgery is reported to be useful [ 5 , 6 ]. NBI is a digital-optical image-enhanced endoscopy method that enables early detection of malignancy, grade of malignancy, and diagnosis of the extent of malignancy through highlighting differences in mucosal color tone, and it is also increasingly being used for non-malignant lesions in the head and neck region [ 7 , 8 ].…”

Extracapsular Dissection With Narrow-Band Imaging Using the Transnasal Endoscopic Tri-port Approach for Extracranial Trigeminal Schwannoma: A Case Report

The pterygopalatine fossa and infratemporal fossa are often approached through an external incision because of their deep facial location, but this can present problems such as facial scarring and deformity. In schwannoma surgery, intraneural dissection is a useful surgical technique for achieving gross total resection while preserving the capsule, including the nerves. For appropriate enucleation and preservation of the functional nerve, it is indispensable to distinguish between the pseudocapsule and the tumor capsule. This case report presents a case of endonasal surgical intervention for an extracranial trigeminal schwannoma employing the tri-port approach and narrow-band imaging.
