To clarify the orientation, classification, and relationships of the greater superficial petrosal nerve (GSPN), and to provide a detailed description on the microsurgical anatomic features and some landmarks to its identification. ⋯ The relationships between the GSPN and its surrounding structures were studied. The vulnerability of the GSPN is attributed to diverse factors. We confirmed the communication branches between the GSPN and the GN. Our study is important to the understanding of the relationship of the GSPN with adjacent structures and will improve further information during skull base operations.

Percutaneous balloon rhizotomy for trigeminal neuralgia using three-dimensional fluoroscopy.
Percutaneous balloon rhizotomy is one of the standard techniques for the treatment of trigeminal neuralgia. However, there have been well-reported complications from cannulating the foramen ovale (FO). We describe a novel technique for cannulating the FO using 3-dimensional (3D) rotational fluoroscopy. ⋯ Three-dimensional rotational fluoroscopy allows real-time visual guidance to cannulate the FO and determine the optimal position of the inflated balloon. We believe that this is an important adjunct for treating trigeminal neuralgia via percutaneous techniques.

To evaluate risk factors for the development of dysphagia after anterior cervical surgery. ⋯ In our patients, the incidence of dysphagia was low, and it had completely resolved at 12 months in all cases. Risk factors for dysphagia were multilevel procedures, involvement of C4-5 and C5-6, and age.
