Neuroendoscope-assisted Microsurgery Treating Lesions in Cerebellopontine Angle

Objective: To discuss the practicality and advantages of the techniques treating the lesions in cerebellopontine angle with neuroendoscope-assisted microneurosurgery via retrosigmoid approach.Methods:Neuroendoscope-assisted microneurosurgery via retrosigmoid approach treating 76 cases of lesions in cerebellopontine angle.Results:25 cases of acoustic neuromas were completely removed with 100% facial nerves anatomically preserved.Functional preservation rate was 92%.21 cases of epidermoid cyst and 8 cases of meningioma were totally removed.6 cases of hemifacial spasm were cured.Postoperative paroxysmal pain disappeared in 9 cases of trifacial neuralgia.7 cases of meniere were cured.No death and complication were found.Conclusion:Endoscope-assisted microsurgery treating lesions in cerebellopontine angle can reduce the damage to cerebellum,brainstem,blood vessels and nerves.At the same time this method can reduce complications,operative risk and improve the operative effect.
