![]() | Media file 1: A tympanomeatal flap is incised along the posterior external auditory canal. |
![]() | Media file 2: The fibrous tympanic annulus is elevated with the tympanomeatal flap to expose the middle ear. |
![]() | Media file 3: Scutal bone is curetted to allow visualization of the pyramidal process, tympanic segment of the facial nerve, and the stapedial footplate. |
![]() | Media file 4: The incudostapedial joint is disarticulated after measurements have been made. |
![]() | Media file 5: The stapedial tendon is sectioned either with a laser or scissors and then the posterior crus of the stapes is sectioned either with a drill as shown or a laser. |
