Abstract: 

BACKGROUND AND OBJECTIVES: TYMPANOPLASTY AND MASTOIDECTOMY ARE SURGICAL PROCEDURES PERFORMED IN THE CASES OF MIDDLE EAR INFECTION. TYMPANOPLASTY IS AN OPERATION FOR ERADICATING MIDDLE EAR INFECTION AS WELL AS THE RECONSTRUCTION OF THE HEARING MECHANISM. WHEN, ACCORDING TO PREOPERATIVE EXAMINATION, AUDIOMETRY FINDINGS AND INTRAOPERATIVE FINDINGS, THERE IS ANY DOUBT IN ERADICATING THE PATHOLOGY FROM THE MIDDLE EAR, THE SURGEON (OTOLOGIST) DECIDES WHETHER OR NOT TO PERFORM A MASTOIDECTOMY IN ADDITION TO TYMPANOPLASTY. MASTOIDECTOMY HAS BEEN PROVEN TO BE BENEFICIAL IN ERADICATING THE PATHOLOGY IN THE PRESENCE OF CHOLESTEATOMA AND GRANULATION TISSUE AND RECALCITRANT CHRONIC ACTIVE INFECTION; HOWEVER, IN THE CASES OF SIMPLE PERFORATION OF THE TYMPANIC MEMBRANE WITHOUT CHOLESTEATOMA OR ACTIVE INFECTION, PERFORMING A MASTOIDECTOMY IN ADDITION TO TYMPANOPLASTY IS CONTROVERSIAL. THEORETICALLY, MASTOIDECTOMY IMPROVES MIDDLE EAR AERATION AND THE SUCCESS OF TYMPANOPLASTY.
METHODS AND MATERIALS: IN THE PRESENT STUDY, 60 CASES WITH MIDDLE EAR INFECTION AND SIMPLE PERFORATION OF THE TYMPANIC MEMBRANE WERE RANDOMLY DIVIDED IN TWO SUBGROUPS OF 30 CASES. ONE GROUP UNDERWENT A TYMPANOPLASTY PROCEDURE AND THE OTHER ONE, TYMPANOPLASTY WITH A MASTOIDECTOMY PROCEDURE. THE SUCCESS RATE OF THE OPERATION IN THE TWO SUBGROUPS CONCERNING THE TYMPANIC MEMBRANE GRAFT CONDITION AND HEARING IMPROVEMENT WAS CAPARISONED AFTER TWO MONTHS.
RESULTS: IN THE TYMPANOPLASTY GROUP, THREE CASES, AND IN THE TYMPANOPLASTY-MASTOIDECTOMY GROUP, TWO CASES OF POSTOPERATIVE PERFORATION OF THE MEMBRANE WERE FOUND. GRAFT SUCCESS RATE IN THE FORMER GROUP WAS 90% AND IN THE LATTER 93.3%. STATISTICALLY, THE DIFFERENCE BETWEEN THE TWO GROUPS IN TERMS OF HEARING IMPROVEMENT AND GRAFT SUCCESS RATE IS NOT SIGNIFICANT.
CONCLUSION: MASTOIDECTOMY WITH TYMPANOPLASTY IS NOT NECESSARY IN SIMPLE PERFORATION OF THE TYMPANIC MEMBRANE FOR BETTER GRAFT ACCEPTANCE AND BETTER AUDIOMETRY RESULTS.
