Selective trigeminal root section via an endoscopic transpyramidal retrolabyrinthine approach.
Present experience supports the view that endoscopic access to the cerebellopontine angle has proved an easy and safe therapeutic (selective trigeminal root section in cases of Vth nerve neuralgia) and diagnostic (inspection in cases of otherwise  undetectable tumours) method, offering the advantages of little surgical risk and high effectiveness.
