Аннотация
Primary stapedectomies were performed on 60 patients with bilateral otosclerosis. Every patient had a 4 mm long Robinson prosthesis with a 0.4 mm wide shaft placed in one ear and a 4 mm long Robinson prosthesis with 0.6 mm wide shaft placed in the opposite ear. With the 0.4 mm wide prosthesis, 54 patients overclosed the air bone gap and 6 were within 10 dB of closing. With the 0.6 mm wide prosthesis, which was placed in the opposite ear, 51 patients overclosed their air-bone gap and 8 were within 10 dB of closing. We conclude that there is no statistical difference in hearing results between the 0.4 mm and the 0.6 mm wide Robinson prosthesis when they are used in a partial stapedectomy with a vein graft covering the oval window.
