Endoscopic Type 1 Tympanoplasty in Chronic Otitis Media: Comparative Study with a Postauricular Microscopic Approach:

ObjectiveTo compare surgical outcomes after tympanoplasty without ossiculoplasty for chronic otitis media between transcanal endoscopic ear surgery (TEES) and postauricular microscopic ear surgery (PAMES).Study DesignCase-control study.SettingTertiary care university hospital.Subjects and MethodsConsecutive patients (N = 122) who had undergone tympanoplasty without ossiculoplasty for chronic otitis media were enrolled in this retrospective study and divided into 2 groups: TEES (n = 47) and PAMES (n = 75). Middle ear condition was graded with the middle ear risk index. Hearing, repair of tympanic membrane perforation, and surgical time were assessed.ResultsThe surgical success rate for hearing (air-bone gap ≤20 dB) was 95.7% in the TEES group and 84.0% in the PAMES group. Lower middle ear risk resulted in similar mean (95% CI) closure of air-bone gaps (TEES: 9.6, 6.5-12.6; PAMES: 8.0, 6.4-9.7; P = .333), whereas higher middle ear risk demonstrated significantly larger closure of air-bone gaps for the TEES ...
