Does the material of stapes prosthesis infl uence hearing improvement in stapes surgery – retrospective analysis of 350 cases
Journal Title: Otolaryngologia Polska - Year 2008, Vol 62, Issue 4
Abstract
Aim. Retrospective analysis of the post-op hearing results in stapes surgery using different types of materials for stapes prosthesis after 12 months follow up. Material and methods. The total number of 350 otosclerosis patients who underwent surgical treatment at the Otosurgery Department, Medical University of Lodz from 1980–2002. All patients included in the study were divided into 4 groups: group 1 (N=54) – Portmann’s method interposition, group 2 (N=160) – stapes replaced with the Shea – type prosthesis, group 3 (N=60) – platinum wire prosthesis (Zini – type), group 4 (N=76) – tefl on-piston operation (Fisch – type). Results. The 12 months post-op mean value for air-bone gap (500, 1000, 2000 Hz) presented the following values: group 1–19 dB, group 2–15.9 dB, group 3–18.4 dB, group 4–13.5 dB. The percentage of patients with the mean air-bone gap value of 15 dB or less (500, 1000, 2000 Hz) has the following values in each group: group 1–75%, group 2–81.3%, group 3–83%, group 4–85 %. Conclusions. 12 months post-op hearing results compared between the 4 studied groups showed statistically not signifi cant differences. Our experience with tefl on-piston prosthesis shows the lowest postop mean value of the air-bone gap.
