title: [Transmaxillary approach to the skull base: surgical anatomy and guidelines].
abstract: BACKGROUND
  A surgical and anatomic approach to the skull base using the transmaxillary route is presented. This route is well-known and used for a long time for sinus conditions.
  
  
  METHODS
  This study was performed on injected cadavers. This study describes step by step this approach in microsurgical conditions following a vital lead: the infraorbital nerve.
  
  
  RESULTS
  Anatomical landmarks are located in order to avoid complications. These complications are on one hand, hemorrhages by vascular lesions and on the other, definitive nerve palsy.
  
  
  CONCLUSIONS
  Several skull base approaches exist, transfacial routes produce cosmetic damages. This route preserves the functional anatomy of the nose because it preserves the integrity of the lateral wall of the nasal cavity.
