OBJECTIVE: To evaluate the role of Circumferential Subannular Tympanoplasty [CST] in cases of Revision tympanoplasty.
METHODS: A retrospective statistical analysis of data of 81 patients who underwent revision tympanoplasty with CST technique [essentially Type I tympanoplasty] was done. An intact graft at the end of 6 months was regarded as a surgical success.
RESULTS: Overall, we recorded a surgical success rate of 97.5% [79 out of 81 cases] with a 100% surgical success for anterior perforations. There was no impact of size or site of perforation on the outcomes of revision tympanoplasty by this technique. In addition, a statistically significant hearing improvement was recorded in the study. The mean pre-operative and post-operative ABG were 33.85 dB and 18.87 dB respectively. The mean ABG closure was 14.89 dB. The value of "p" by Chi square test was found to <.05.
CONCLUSION: CST is an excellent technique for revision tympanoplasty and seems to address the shortcomings of conventional onlay and inlay techniques.
