Abstract Cartilage graft tympanoplasty has a better success rate in the treatment of chronic otitis media if properly prepared pre-operatively and placed intraoperative. To prepare cartilage graft from tragus and to compare preoperative and postoperative hearing. 35 patients with chronic otitis media of tubotympanic type, without intra/ extra cranial complications disease were made to undergo cartilage tympanoplasty. The study was conducted prospectively. In this technique, patients had an average improvement in hearing up to 10–12 dB. The mean postoperative period follow up was 2–6 months. If cartilage graft is properly prepared and placed, cartilage tympanoplasty appears to provide better success rates and hearing results. Keywords Tragus Cartilage tympanoplasty Tubo-tympanic
Introduction The aim of tympanoplasty is to close the tympanic membrane perforation, restore hearing and reconstruct a healthy middle ear cavity. In 1952, split thickness graft was used by Wullstein for repair of the tympanic membrane and published the results [1]. Zollner described his experiences with a similar graft [2]. Although tympanoplasty is a highly
successful procedure in 70–90% of normally ventilated middle ears, the prognosis is poorer in cases with total dysfunction, adhesive processes, infection, tympanic fibrosis and defect of the entire tympanic membrane. Many autogenous, several allogeneic (homogeneous), and a few xenogenous graft materials have been used for ear drum perforation closure and reconstruction of the middle ear and ear canal [3]. The major advantage of cartilage is its stiffness and bradytrophic metabolism, which make it particularly suitable for difficult conditions, such as subtotal perforations, adhesive otitis and revision cases [4, 5]. The aim of the present study was to prepare the cartilage graft material and to evaluate its effect on the success rate on functional outcomes on hearing. Cartilage graft has proven to be promising in closing TM perforations. Cartilages are harvested from tragus, concha were used. Its’ rigidity in comparison to temporalis fascia, manages to prevent resorption, retraction, and re-perforation, despite continuous Eustachian tube dysfunction. It is less likely to cause an inflammatory reaction or an infection postoperatively. Many studies have proven that the middle ear tolerates cartilage very well showing long-lasting survival.
