To Compare Short and Long-Term Graft Uptake and Hearing Outcome of Type I Cartilage Tympanoplasty Between Small, Medium and Large Perforations Using Reinforced Sliced Conchal Cartilage.

Abstract

To compare short and long-term graft uptake and hearing outcome of type I cartilage tympanoplasty between small, medium and large perforations using reinforced sliced conchal cartilage. A retrospective study conducted in a tertiary center. Fifty patients who under went type I tympanoplasty were enrolled. Their mean age was 29.30years and follow-up time was 6 and 18months. The preoperative, postoperative short-term and long-term hearing and graft uptake results were analyzed. Graft uptake rate was 96% in short-term and 98% in long-term with one residual perforation in medium size, but 100% in small and large perforations (P < 0.01). Short and long-term ABG closure was identical in small and medium size perforation (P = 0.978) (P = 0.734), but, large perforation showed significant improvement in long-term (P = 0.012). Sliced conchal cartilage reinforced with temporalis fascia is a reliable technique for tympanoplasty. In long-term, large perforations have better graft uptake rate and continuous hearing improvement and ABG closure than small and medium perforations.
