Abstract:
BACKGROUND AND OBJECTIVES: Bone defect of the attic wall is a critical cause of the postoperative retraction pocket after canal wall up mastoidectomy. So, proper treatment of the attic defect is important and attic reconstruction is an acceptable procedure but it is controversial when the attic is reconstructed or not. The aim of this study is to analyze the usefulness of the attic reconstruction using tragal cartilage and perichondrium for prevention of retraction pocket and propose the indication to perform the attic reconstruction. SUBJECTS AND METHODS: We retrospectively reviewed the medical records of 46 consecutive patients who underwent tympanomastoidectomy and attic reconstruction using tragal cartilage between January 2005 and January 2009. The follow-up period varied from 12 to 65 months, with the average period of 34 months. We analyzed postoperative status of the scutum and the tympanic membrane, and development of the residual or recurrent cholesteatomas and evaluate development of the retraction pocket according to the preoperative size of the bony defect of the scutum and status of the ossicular chain. RESULTS: Retraction pocket was developed in the 13% of the operations and most of the cases had large attic destruction more than 3 mm and destructed ossicular chain. CONCLUSIONS: Attic reconstruction using tragal cartilage is a simple method to repair the bony defect of the external ear canal and effective in preventing postoperative retraction pocket if the size of destructed scutum is less than 3 mm.
