Abstract
Ossicular discontinuity is one of the most common causes of conductive hearing loss. Ossicular chain reconstruction improves conductive hearing loss. With no additional cost, cartilage ossiculoplasty is easy to perform, and also the cartilage is well tolerated being an autograft. In this study we compared the audiological outcome in ossiculoplasty done by cartilage umbrella, cartilage boomerang and alloplastic TORP. 75 patients of age group 10-50 years clinically diagnosed with chronic otitis media with conductive hearing loss and an air bone gap (ABG) of at least 20 dB posted for surgery were included. Ossiculoplasty was done in three groups with autologous cartilage boomerang, cartilage umbrella and alloplastic TORP. In mucosal disease hearing gain was better in umbrella technique (17.66 ± 1.1) dB than Boomerang (16.9 ± 0.8) dB and TORP (10.68 ± 0.9) dB. ABG closure was higher in Boomerang and TORP. Hearing improvement in patients with squamosal disease managed by canal wall up surgery was 25.01 ± 1.1 dB, 27.73 ± 3.1 dB and 20.12 ± 1.8 dB in Boomerang, Umbrella and TORP group respectively showing that umbrella method gave maximum improvement. ABG closure was better in TORP group. In canal wall down surgery patient's maximum improvement was seen in Boomerang (29.51 ± 0.9) dB followed by Umbrella (26.67 ± 1.2) dB and TORP (25.27 ± 0.8) dB group. ABG closure was higher in Boomerang group. Cartilage ossiculoplasty is a reliable and effective method of ossicular chain reconstruction for both mucosal and squamosal disease. Cartilage ossiculoplasty has the added advantage of reduced chances of prosthesis extrusion as compared to TORP.
