Comparison of incus interpositioning technique versus glass ionomer cement application in type 2 tympanoplasty

Abstract

Objective of this study is to compare glass ionomer cement application and incus interpositioning techniques in patients who have chronic otitis media, conductive hearing loss with intact tympanic membrane and who undergo hearing reconstruction of staged surgery using a retrospective chart review in the setting of Ministry of Health Ankara Training and Research Hospital ENT Clinic, Turkey. We retrospectively evaluated patients who underwent otological surgery and hearing reconstruction with auto graft incus during 2005-2008 or glass ionomer cement during 2008-2010. Patients who had cholesteatoma, stapes fixation and tympanosclerosis were excluded. Postoperative mean follow-up time of 107 patients was 9.8 months (6-38 months, 83.2 % of them was ≤ 9 months). Postoperative pure tone hearing thresholds, graft status, gain scores and air bone gaps were recorded. Intact graft, dry ear on the operated side and ABG scores less than 20 dB were accepted as surgical success. Preoperative ABG score was 30.6 ± 7.93 dB in glass ionomer (group I) and 33.6 ± 11.99 dB in incus interpositioning (group II). Postoperative ABG scores were 13.6 ± 10.40 and 22.6 ± 12.39 dB, respectively, in group I and II. Success of closure in ABG scores was obtained in both groups (p < 0.001). Gain scores in group I were better (p = 0.035). Graft success (p = 0.020) correlated with gain score. Results showed that the glass ionomer cement application is a good, cost-effective technique, easy to perform and yields better hearing scores and lower complication rates compared to incus interpositioning technique.

Erosion of the long process of the incus with incomplete ossicular discontinuity in simple chronic otitis media: Should we reconstruct or leave it be?

Management of Incus Defects in Children: Comparison of Incus Transposition Versus Glass Ionomer Cement

“…Recently, it has been frequently used by otologist and neuro-otologist for ossicular chain reconstruction, stabilization of implantable devices (Teflon piston, ossicular implant, etc), mastoid obliteration and repair of bony defects of tegmen, external ear canal, or skull base. 5 Although the outcomes of the repair of incus long process defects using GIC rebridging and IT technique are widely discussed in adults, [6][7][8][9] there is a paucity of study investigating the results in the pediatric population. This study aimed to evaluate and compare the anatomical (graft take) and functional results (hearing threshold, air-bone gap [ABG], hearing gain) in pediatric patients treated with GIC and IT ossiculoplasty at our tertiary center.…”

Comparison of Hydroxyapatite Prosthesis and Incus Interposition in Incus Defects

“…Because of chronic inflammation in chronic otitis media; ossicle chain defects can be observed most frequently in incus long process. In the reconstruction of these defects, materials such as autograft incus, teflon, hydroxyapatite, ceramic, bone cement, and metal prosthesis are used (1).…”
