Abstract:
Purpose: To evaluate hearing outcome and fate of LPIRP (lenticular process of incus replacement prosthesis) prosthesis in the reconstruction of erosion of long process of the incus. Methods: In this retrospective descriptive study 17 patients with erosion of long process of incus who were operated (reconstructed with LPIRP prosthesis) between January 2015 to December 2017 in a tertiary care center were included. The hearing outcome was evaluated by comparing mean PTA and mean ABG preoperatively and postoperatively at the end of 3 months and 18 months. The graft uptake rate, reperforation, and extrusion of the prosthesis were assessed using otoendoscopy. Results: Preoperative mean PTA was 53.8 dB while mean postoperative PTA was 36.6 dB and 33.4 dB at the end of 3 and 18 months respectively (p-value ˂ 0.05). The mean preoperative ABG was 30.2 dB while the postoperative mean was 13.4 dB and 11.2 dB at the end of 3 months and 18 months respectively (p < 0.05). Extrusion with re-perforation was seen only in one case 1/17 (5.8%). Conclusion: LPIRP has all the characteristics for an ideal middle ear implant which is a cost-effective alternative in the reconstruction of an eroded long process of the incus.
