Efficacy of evaluation of audiometric results after stapes surgery in otosclerosis. II. A method for reporting results from individual cases

Otolaryngol Head Neck Surg. 2001 Jan;124(1):84-9. doi: 10.1067/mhn.2001.111600.

Abstract

To standardize the reporting of hearing results after middle ear surgery, the Committee on Hearing and Equilibrium of the American Academy of Otolaryngology-Head and Neck Surgery proposed 2 levels of guidelines: level 1 for reporting summary data and level 2 for reporting raw data. The Committee encourages the reporting of raw data from each individual case. However, in studies in which the examined population is too large, this can yield difficulties. With respect to this point, we designed a method for a simple visual presentation of hearing results in an attempt to provide data from each individually operated ear in a patient group. In this method the relation between the preoperative and postoperative bone-conduction levels is evaluated to assess overclosure and iatrogenic cochlear damage, and the relation between postoperative gain in air conduction and the preoperative air-bone gap is evaluated as a measure of technical success rate. This results in 2 plots, which we called the Amsterdam Hearing Evaluation Plots. Audiometric data from 451 stapes operations were used to demonstrate the use of the Amsterdam Hearing Evaluation Plots.
