Absence of the stapes suprastructure is a poor prognostic indicator of hearing outcome, which necessitates an effective reconstruction technique for ossicular continuity and restoration of middle ear volume. In the present study, we used a boomerang-shaped conchal cartilage graft.<\/jats:p><jats:p>\n          Objective\u2003To evaluate the improvement in hearing using a boomerang-shaped conchal cartilage graft for Type III tympanoplasty in cases of CSOM-AAD in which the stapes suprastructure was absent and to study the incidence of intraoperative\/postoperative complications of this procedure.<\/jats:p><jats:p>\n          Method\u2003A total of 21 patients with CSOM-AAD who were found to have absent stapes suprastructure intraoperatively were included. A boomerang-shaped conchal cartilage graft was placed over the stapes footplate for reconstruction following canal wall down mastoidectomy. Pure tone audiogram (500, 1,000, 2,000 and 4,000\u2009Hz) was done preoperatively and at 12 weeks postoperatively. Hearing outcome and incidence of complications were noted.<\/jats:p><jats:p>\n          Results\u2003There was a statistically significant reduction in the hearing loss for air conduction and air-bone gap (ABG) of 6.1\u2009dB and 6.9\u2009dB respectively (p\u2009&lt;\u20090.05). Air-bone gap\u2009&lt;\u200930\u2009dB could be achieved in 71.4% of the patients as compared with 23.8% preoperatively. No significant difference was noted in the bone conduction threshold (p\u2009&gt;\u20090.05). A better hearing outcome was observed at higher frequencies (2,000, 4,000\u2009Hz). No major complications were encountered.<\/jats:p><jats:p>\n          Conclusion\u2003A boomerang-shaped conchal cartilage graft is effective when used for Type III tympanoplasty, especially at higher (2,000, 4,000\u2009Hz) frequencies, and is comparable to newer materials such as titanium total ossicular reconstruction prosthesis (TORP). No major intraoperative\/postoperative complications were noted.<\/jats:p>","DOI":"10.1055\/s-0040-1712934","type":"journal-article","created":{"date-parts":[[2020,6,30]],"date-time":"2020-06-30T22:56:05Z","timestamp":1593557765000},"page":"e289-e295","source":"Crossref","is-referenced-by-count":2,"title":["Effect
