Effects of perforation size on the success rate of tympanoplasty using a cartilage graft

چکیده
ere, we review the article entitled ‘‘Impact of cartilage raft size on success of tympanoplasty’’ by Abdelhameed t al.1 The authors evaluated the effects of different peroration sizes on the outcomes of Type 1 tympanoplasty in his study. The work described is interesting. However, the nclusion criteria and the results are not very clear. The uthors do not state whether patients with myringosclerois were included in the methods section. Myringosclerosis ffects the blood supply to, and nutrition of, the eardrum, ausing graft failure after Type 1 tympanoplasty. Migirov t al.2 believed that appropriate freshening of the perforaion edges, with removal of sclerotic plaques, improved the uccess rate of tympanoplasty in patients with myringoscleosis. The study divided 50 patients into three groups. Group had perforations of more than 50% of the Tympanic Memrane (TM); Group II had perforations of between 25% and 0% of the TM; and Group III had perforations ≤25% of the M. The three groups contained 16, 20, and 14 patients, espectively.1 The authors write in the Results: ‘‘Fifty atients underwent cartilage tympanoplasty, thirty seven atients had unilateral perforation, while 13 had bilateral erforations. The anatomical success rate defined as graft ake after 12 months of follow up among all patients was 2%, 4 patients underwent revision surgery 10--12 months

Introduction: The use of cartilage as a grafting material has been advocated in cases where there is a high risk of graft failure, such as subtotal perforations, adhesive processes, and residual defects after primary tympanoplasties. The purpose of this study was to compare the graft acceptance rates and auditory outcomes of cartilage tympanoplasty operations using a palisade technique with tho...

Materials and Methods: In a prospective study, based on the results ...
متن کاملImpact of cartilage graft size on success of tympanoplasty.
INTRODUCTION In the last decade, there has been an increasing use of cartilage grafts in the primary repair of tympanic membrane perforations. The major advantages of cartilage are its stiffness and its very low metabolic requirements, which make it particularly suitable for difficult conditions, such as subtotal perforations, adhesive otitis and reoperation. OBJECTIVE To analyze the impact o...
