Picture of a left mastoidectomy, surgeon's view.^[2]
In this left canal wall up mastoidectomy, the tympanic membrane has been elevated forward and a cholesteatoma sac is visible in the attic.^[3]
This patient has a recurrent cholesteatoma which has found its way to the surface of the post-auricular skin, forming a mastoid cutaneous fistula.^[4]
This cholesteatoma sac has eroded the lateral surface of the mastoid bone and was found immediately under the post-auricular skin.^[5]
Left canal wall down mastoidectomy.This patient had a modified radical mastoidectomy with tympanoplasty. The posterior bony canal has been removed and part of the dry "mastoid bowl" is visible posterior and superior to the reconstructed tympanic membrane ^[6].
