THE RETROSIGMOIDAL APPROACH IN OTONEUROLOGICAL SURGERY / 解放军医学杂志

Otoneurological operations were performed in 96 patients through the retrosigmoidal approach. The anatomical structures in the cerebello-pontine angle can be clearly exposed with this procedure. The approach has the advantage that it is of convenience in manipulation with only gentle trauma, and that some drawbacks of suboccipital or retrolabyrimhine approach may be overcome. On the other hand, operation indications can be extended and operation complications reduced. It is an ideal approach which enters the cerebello-pontine angle. The surgical technique and clinical experience have been reported in detail in this paper.
