Abstract
- It is important to decide which procedure to employ between canal wall up mastoidectomy and canal wall down mastoidectomy (CWDM) as each procedure has its own advantages and disadvantages. To combine the advantages and compensate the disadvantages of each procedure, various methods and approaches have been devised. Mastoid and epitympanic obliteration, which minimizes the dead space in the mastoid cavity, was previously known to prevent the occurrence of retraction pockets. We performed mastoid and epitympanic obliteration also to prevent the occurrence of cavity problems without meatoplasty. Here we describe the surgical procedures for modified CWDM without meatoplasty and mastoid obliteration using autologous materials.
