BACKGROUND Vidian nerve schwannoma is an extremely rare type of facial nerve schwannoma. To the best of our knowledge, only 1 case has been reported. METHODS We report an additional case of vidian nerve schwannoma with middle cranial fossa extension in a 49-year-old Japanese woman. The surgical approaches for infratemporal fossa schwannomas are reviewed, and the maxillary swing approach we us...

OBJECTIVES/HYPOTHESIS Demonstrate the endoscopic anatomy of the palatovaginal (PV) canal and artery for identification and dissection of the vidian nerve during endoscopic transpterygoid approaches. Evaluate the length of the PV canal and its relation with the vidian nerve. Show that the traditionally known PV canal is a misnomer and should be renamed. STUDY DESIGN Experimental study: anatomi...

OBJECTIVE To explore the vidian nerve anatomy by endoscopy and paranasal sinus computed tomography (CT) to elucidate the appropriate surgical approach based on preoperative CT images. DESIGN Retrospective analysis. SETTING Tri-Service General Hospital, National Defense Medical Center, Taipei, Taiwan, Republic of China. PATIENTS Sixty-seven patients underwent 106 endoscopic vidian neurecto...

Vidian nerve schwannomas are highly unusual, with only two reported cases in the world literature, and present with a constellation of symptoms that may be extremely vague. In the reported cases, open techniques have been utilized that required significant dismantling of the midfacial skeleton to access and manage these skull base lesions. Over the last 15 years, a paradigm shift in base of sku...

One of the constant side-effects of a successful transantral vidian neurectomy, well-known among otolaryngologists, is the interruption of the secreto-motor nerve supply to the lacrimal gland. Since this secreto-motor nerve supply is concentrated in the nerve of the pterygoid canal (vidian nerve) this is only to be expected. This depression of lacrimation appears to be permanent, yet in some 30...

background and importance: our learning curve during two decades of neurosurgical practice has been changed from an abstractive to a more meaningful and conductive state. in cases of fifth nerve neurinoma, pre-operative anatomopathologic diagnosis could lead us to a pre-planned program during and after the surgery to get the safe surgical result. case presentation: representation of two complex...

INTRODUCTION To present a case of a child with a desmoplastic fibroma of the vidian canal, compressing the vidian nerve. CASE REPORT A 12-year-old girl with several years' history of right-sided facial pain was referred to our institution. Magnetic resonance imaging and computed tomography scans showed an expansile mass involving the right vidian canal. The patient underwent a complete endosc...

INTRODUCTION The type of endoscopic approach chosen for vidian neurectomy can be specified by evaluating the vidian canal and the surrounding sphenoid sinus structures. OBJECTIVE The variations and morphometry of the vidian canal were investigated, focusing on the functional correlations between them which are crucial anatomical landmarks for preoperative planning. METHODS This study was pe...
