IntroductionIn the last decade, there has been an increasing interest in using cartilage grafts as the primary alternative. The major advantages of cartilage are its stiffness and bradytrophic metabolism, which make it particularly suitable for difficult conditions, such as subtotal perforations, adhesive otitis and reoperation.ObjectiveIs to analyze impact of different perforation sizes hence different sizes of cartilage on the anatomical and functional outcome of tympanoplasty.MethodsThrough this prospective non-controlled, non-randomized study, 50 patients underwent cartilage type 1 tympanoplasty (20 females and 30 males), with a mean age of 19.3±9.8 years. According to size of perforation, patients were subdivided into three groups, Group I had perforation >50% of tympanic membrane area, Group II patients with perforation 25–50% of tympanic membrane area, Group III perforation was ≤25% of tympanic membrane. They had done pre and postoperative Pure Tone Average (PTA)–Air Bone Gap (ABG) for tested frequencies (0.5, 1, 2, 4kHz). All patients were followed up at least 12 months after operation.ResultsThe anatomical success rate among all patients was 92%, all groups showed statistical significant improvement between pre and postoperative (PTA–ABG), among the three groups, no significant correlation between size of cartilage graft and degree of (ABG) improvement was noticed.ConclusionSize of cartilage graft has no impact on degree of hearing improvement or anatomical success rate after tympanoplasty.
