ABSTRACT
We treated 50 patients at the Hospital de Especialidades, Centro
Médico Nacional La Raza, IMSS, in Mexico City, with trigeminal
neuralgia by two procedures: a) microvascular decompression
of the trigeminal nerve with asterional craniectomy, or b) compression
of Gasser’s nodule by percutaneous puncture. Each
patient was allowed to choose one of the procedures after
informed consent.
Twenty two patients underwent percutaneous puncture, while 28
patients underwent microvascular decompression.
Our study group comprised 35 females and 15 males between the
ages of 38 and 80 years. After 3 months, we achieved good-toexcellent
results in 25 patients with microvascular decompression
and in 15 patients, with compression of Gasser’s nodule.
At 2 years follow-up, our results remained the same for
microvascular decompression group while in the other group
we observed only satisfactory results in 59% of cases.
In craniectomy group, we found vascular compression in 96%
of cases. Five patients presented hypoacusia after decompressive
procedure and eight patients had facial dysesthesia after
percutaneous procedure. In percutaneous group, procedures
were cancelled due to technical difficulties in two cases.
We conclude that both procedures are safe, with zero mortality.
The microvascular procedure affords better results at 2 years
follow-up.
