Could tympanometric volume be a useful tool to predict the success of type I tympanoplasty in simple chronic otitis media

Background: Middle ear aeration level is an important precursor of chronic otitis media (COM) and one predictive factor for tympanoplasty success. Tympanometry measures the volume external canal, middle cavity, aditus, mastoid air cells in patients with tympanic membrane (TM) perforation. The aim study was to determine whether pre-operative tympanometric interaural differences unilateral simple COM can predict success type I tympanoplasty. Methods: Retrospective analysis tympanoplasties performed adults between January 2017 December 2020 a tertiary hospital. Bilateral COM, revision surgery using cartilage grafts or associated other procedures were excluded. Success defined as no evidence TM perforation on otoscopic examination tympanogram, at least six months after surgery. Results: Sixty-one evaluated. mean age 43 years old, there female predominance (55.7%). overall rate 77%. Location size weren’t different among without surgical We found statistically significant result (p=0.009) regarding differences, median 2.7 ml (IQR 3.6) group 1.3 1.26) recurrence group. 90.6% difference greater than 2 had successful Conclusions: A good ear, demonstrated by higher
