Objective:
To explore the feasibility of endoscopic surgery for primary trigeminal neuralgia, and to evaluate its advantages and disadvantages.
Methods:
Fifteen patients diagnosed as primary trigeminal neuralgia were included in this study. All of them had maxillary neuralgia, concurrently with 8 ophthalmic neuralgia and 2 mandibular neuralgia. The median course of disease was 4 years. The surgeries were performed by transnasal endoscope, through sphenopalatine foramen, into the pterygopalatine fossa, to find rotundum foramen, and then coagulated and cut the maxillary nerve. Post-operative evaluation was done based on Brisman R' s way. The post-operative improvement of symptom was compared with preoperative symptom, and the complications of this operation were observed.
Results:
The follow-up time was 6 months to 16 months, with the median time of 13 months. Thirteen patients were cured, 2 patients had effective outcome. Seven months after operation, 1 patient appeared supraorbital neuralgia. After the radiofrequency operation, the pain was improved. All of the patients had no serious complications and no subjective discomfort of nose and eyes.
Conclusions:
The surgery for primary maxillary neuralgia under transnasal endoscope had a direct way to rotundum foramen, with clear operative vision. It is a minimally invasive surgery, it can minimize the serious complications. The primary curative effect is confirmed.
