title: [An anatomical investigation relating to the stapes elevation surgery].
abstract: OBJECTIVE
  For the purpose of improving patient's hearing in stapes elevation surgery.
  
  
  METHODS
  The anatomical features relating to this operation were observed and measured in 30 ears of fresh cadavers, which included the length of lenticular process, the highness of stapes head and neck, the thickness of lower border of footplate, the angle of incudostapecial joint and the gradients of upper and lower wall of vestibular niche. The relation between two types of the present operation and the investigation were discussed.
  
  
  RESULTS
  The two types of present operations were in accord with the physiologicoanatomical features of the stapes and incus.
  
  
  CONCLUSIONS
  In order to improve the patient's hearing, making use of biobinder for strengthening the incudostapedial connexion as a routine is suggested.
