The treatment for petroclival epidennoid cyst with neuroendoseope-assisted microneurosurgery

Objective: To disscuss the techniques and metheds of the treatment for petroclival epidermoid cyst with neu-roendoscope-assisted microneurosurgery. , the selection of surgical approach and attention to event during operation were reviewed. Methods: With neuroendoscope-assisted microneurosurgery. 28 patients with petroclival epidermoid cyst were treated. Larger part of the tumor was resected with microneurosurgery, then under neuroendoscope remains of tumors was found out and removed. Result: After the tumors were removed with microneurosurgery, the remains of tumors was fully resected with neuroendoscope. There was no death. Conclusion: The treatment for petroclival epidermoid cyst with neuroendoscope -assisted microneurosurgery is very importance, it can increase the total-resection rate for tumors and reduce complications.
