Abstract

INTRODUCTION: The aim of the study was to compare hearing results between tympanoplasty with attic wall reconstruction and attic obliteration.
MATERIAL AND METHODS: A prospective study included 88 patients who were operated for chronic suppurative otitis media (CSOM) and cholesteatoma in the ENT Department University Clinic Center Banja Luka from 2006 to 2011. Analysis of variance (ANOVA) was conducted to assess the impact of two different techniques of tympanoplasty: attic wall reconstruction and attic wall obliteration on patients` hearing. Hearing outcome was measured comparing preoperative to postoperative pure-tone average (PTA) and postoperative air-bone gap (ABG).
RESULTS: Cholesteatoma was found in 54 (61.4%) patients: 31 (35.2%) sinus cholesteatoma, 20 (22.7%) attic cholesteatoma, 3 (3.4%) tensa tympanic cholesteatoma, and 34 cases (38.6%) of CSOM. Lateral attic wall and ossicular chain reconstruction was performed in 33 cases with subsequent attic reconstruction if the long process of the incus and the incudo-stapedial joint were missing. A mixed between-within-subjects analysis of variance showed significant improvement of PTA postoperatively in comparison to preoperative levels: Wilk`s Lambda=0.33, F(1,86)=172.1, p<0.001. ANOVA showed significant improvement of ABG postoperatively in comparison to preoperative levels: Wilk`s Lambda=0.23, F(1,86)=286.3, p<0.001. Hearing improvement was measured in both cases, the ABG closure and mean PTA improvement was larger in the attic reconstruction compared to attic obliteration technique.
CONCLUSION: Attic wall reconstruction with cartilage provides better postoperative hearing compared to attic obliteration. Attic reconstruction in revision cases for cholesteatoma recurrence is not recommended.
