ABSTRACT

Objectives: To evaluate the success rate and hearing improvement after myringoplasty. Study design: Nonrandomized clinical trial study. Background: Myringoplasty is a surgical procedure used to repair a perforation in the tympanic membrane. Various surgical techniques and graft materials are in practice. Most common indications are to prevent further infection of the ear and to improve hearing. Methods: Nonrandomized clinical trial study was carried out on 61 ears with chronic tympanic membrane perforations, who underwent myringoplasty for the period from September 2010 to July 2012. Post aural approach was performed, using autologous temporalis fascia or conchal cartilage grafts by underlay technique. Results: The study was performed on 61 ears of 59 patients with chronic tympanic membrane perforations, 31(52.54%) were males and 28(47.45%) were females. The mean age of the patients was 27.18 years. Overall surgical success rate was 86.89 % (53 out of 61 ears). The surgical success rate of cartilage grafts myringoplasty was 93.88% and it was 58.33% for fascia grafts myringoplasty. The surgical success rate was 100%, for medium size perforations, and it was 80%. for large size perforations. The significant hearing gain after myringoplasty (more than 10dB) was noticed in 44 out of 53 (83%) of surgical success cases. The mean preoperative air bone gap was 35.28 dB, and it was 15dB for mean postoperative air bone gap of the surgical success cases. Conclusion: Myringoplasty carries high surgical success rate. Cartilage myringoplasty has better surgical success rate than temporalis fascia. The size of tympanic membrane perforation can affect surgical outcome. Hearing gain was significant for both cartilage and temporalis fascia myringoplasty. There was significant difference in relation to hearing gain between conchal cartilage and temporalis fascia myringoplasty in favoring the late.
