The presigmoid retrolabyrinthine approach: Technical note

The retrolabyrinthine approach is classified among the posterior petrosectomies. Its goal to achieve an enlarged mastoidectomy while sparing intrapetrous neurotologic structures in order offer maximal exposure of cerebellopontine angle compound. stages procedure are subsequently skeletonization sigmoid sinus, wide opening mastoid antrum and semicircular canals. We present herein technique, indications limitations approach. a demanding technique. Nowadays routinely combined additional resections petrous bone, so-called “combined petrosectomies”, target jugular foramen or petroclival area.
