Abstract
Objective: Evaluate the success rate for revision tympanoplasty using different graft materials, to compare results of primary and retympanoplasty using the same technique, and to analyze the effect of potential influencing factors on closure of tympanic membrane (TM) and hearing outcome.
Method: Patients who underwent tympanoplasty (n = 617) or re-tympanoplasty (n = 94) for chronic otitis media without cholesteatoma. The different data were analyzed. The temporal fascia, perichondrium, and cartilage-perichondrium composite grafts were used. Ossiculoplasty was performed as needed. The interrelation between preoperative parameters, postoperative morphological outcomes, and functional outcomes was analyzed.
Results: Successful closure rates of the TM perforation were 93.6% and 90.2% in the primary and revision tympanoplasty groups. Graft take rate and hearing results did not depend on graft material. Structural changes were found more frequently in the re-tympanoplasty group (63.4%, compared with 29.5% of primary cases). Ossiculoplasty was performed more often in revision cases (24.4%, compared with 11.4% of primary cases). Successful hearing (ABG within 20 dB) for primary tympanoplasties was achieved in 81.1% and for re-tympanoplasty in 69.5% (P < .01). There were no interrelation between any estimated parameters and the graft take rate for either primary or revision tympanoplasty.
Conclusion: Patients who underwent tympanoplasty (n = 617) or re-tympanoplasty (n = 94) for chronic otitis media without cholesteatoma. Different data were analyzed. The temporal fascia, perichondrium, and cartilage-perichondrium composite grafts were used. Ossiculoplasty was performed as needed. The interrelation between preoperative parameters, postoperative morphological outcomes, and functional outcomes was analyzed.
