Background and Objectives : There are numerous surgical procedures for the treatment of chronic otitis media including cholesteatoma. Canal wall down mastoidectomy is considered to be better procedure for complete removal of the disease but it may result in problematic mastoid cavity. For years, mastoid obliteration technique using various materials have been introduced. The purpose of this study is to report result of partial mastoid obliteration technique using autologous cartilage.
Subjects and Methods : Charts were reviewed retrospectively on thirty-nine patients who underwent open cavity mastoidectomy, meatoplasty and partial obliteration of epitympanic area and sinodural angle from 1997 to 2005. The procedure is summarized to complete canal down mastoidectomy, meatoplasty and obliteration of epitympanum and sinodural angle using cartilage that is harvested from conchal cartilage and cartilaginous portion of external auditory canal when meatoplasty is done, covering with deep temporalis muscle fasica or perichondrium.
Results: The patients became otorrhea free after average of 8 weeks postoperatively, during follow up period of average 46 months, there was one recurrence of cholesteatoma and there were neither graft failure nor severe complicationl.
