Cartilage Reinforcement Tympanoplasty v/s Temporalis Fascia Tympanoplasty in Large Central and Subtotal Tympanic Membrane Perforations: A Comparative Study from East Nimar India
摘要
The aim of this study was to compare the functional results of cartilage reinforcement tympanoplasty with temporalis fascia tympanoplasty in the management of patients with large central and subtotal perforation of tympanic membrane. Present study was carried out in randomly divided two groups of 40 patients each.The mean age of the patients was 33.0 ± 10.6 years ( range between 13 and 65 years) of either sex. Only patients with perforation 50–75% and > 75% were included in the study. Group A included 40 patients in which cartilage reinforcement was done under temporalis fascia during tympanoplasty and Group B included 40 patients in which only temporalis fascia was used for tympanoplasty. Group B showed better graft take results (92.5%) compared to Group A (80%). Group B had lower post op threshold compared to Group A with a statistically significant difference in post op air conduction thresholds in frequencies of 500 Hz (p value = 0.051), 1000 Hz (p value = 0.027), 2000 Hz (p value = 0.030) and 4000 Hz( p value = 0.048).Mean postoperative air bone gap of Group A is 21.5 ± 9.0 dB and Group B 15.6 ± 8.1 dB. There is a statistically significant difference between postoperative air bone gap ( p value = 0.01) between two groups with group B showing better air bone gap closure. Our study concluded that temporalis fascia tympanoplasty is a better technique than cartilage reinforcement in terms of better graft take and hearing outcome.
