“…Endoscopic endonasal surgery was the most common surgical approach for vidian nerve schwannomas (seven out of 10 cases including the current case) [ 1 , 3 , 5 , 7 , 8 , 10 ]. During endoscopic endonasal surgery for removing vidian nerve schwannoma, the operation field, which is usually called "corridor" by skull base surgeons, was created depending on the size and extent of the tumor, but it is usually difficult to resect tumors using the trans-sphenoidal approach alone.…”

Vidian nerve schwannomas are extremely rare, and their surgical management requires an awareness of the surrounding vascular and nervous systems, including the internal carotid artery. Herein, we report a case of a vidian nerve schwannoma that was successfully removed using an endoscopic endonasal approach in a 21-year-old patient who presented with lacrimal hyposecretion. Imaging revealed a large mass extending to the middle cranial fossa posteriorly, to the pterygopalatine fossa laterally, and to the sphenoid sinus medially. The paraclival and petrosal portions of the internal carotid artery were displaced posteriorly. Endoscopic observation of the right nose demonstrated anterior displacement of the inferior portion of the middle turbinate. Based on the above, we suspected a vidian nerve schwannoma, and endoscopic endonasal surgery was performed with particular attention to avoid vascular injuries. An endoscopic transmaxillary approach was used to expose the anterior surface of the tumor. After confirming the pathological diagnosis intraoperatively, intracapsular resection of the tumor was completed using an ultrasonic surgical aspirator with Doppler monitoring of the location of the internal carotid artery. Endoscopic management of the surgical field and preparation to avoid vascular injury are essential for safe and efficient tumor resection.

“…Surgical resection by endonasal endoscopic surgery was the preferred approach, according to the literature. 2 , 4 , 5 The surgical procedure is considered the treatment of choice for symptomatic lesions and the gold standard for diagnosis. The expectant conduct or radiotherapy may be considered, depending on the size of the lesion and the patient's symptoms.…”
