[Routes of approach to the vidian nerve (author's transl)]

The authors describe the various routes of approach to the deep recesses of the pterygo-maxillary fossa. A brief historical review indicates the importance of the work of Golding-Wood who started this type of surgery. Description of the personal technique of the authors via a trans-maxillary approach. Review of the endo-nasal approach of Poch-Vinals by cryotherapy and of M. Port mann by electro-coagulation. A parallel is then drawn between the trans-maxillary approach and the endo-nasal approach of Prades by dissection from the spheno-palatine orifice. The respective indications are discussed.
