Abstract

|
It is important to decide which procedure to employ between canal wall up mastoidectomyand canal wall down mastoidectomy (CWDM) as each procedure has its own advantages anddisadvantages. 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 preventthe occurrence of retraction pockets. We performed mastoid and epitympanic obliteration alsoto prevent the occurrence of cavity problems without meatoplasty. Here we describe the surgicalprocedures for modified CWDM without meatoplasty and mastoid obliteration using autologousmaterials.
