Characteristics of Chronic Suppurative Otitis Media (CSOM) patients who underwent tympanoplasty surgery at Sanglah General Hospital for the period 2017 - 2019

Abstract

Background: One way to deal with deafness from Chronic Suppurative Otitis Media (CSOM) is middle ear reconstruction surgery known as tympanoplasty. The success of surgery is when complete eradication of the disease is possible as well as hearing improvement. This study aims to evaluate the characteristics of chronic suppurative otitis media patients who underwent tympanoplasty surgery at Sanglah General Hospital for the period 2017 – 2019.Methods: A retrospective descriptive study was conducted through secondary data from the medical records of CSOM patients who had undergone tympanoplasty surgery at Sanglah General Hospital in Denpasar during the January 2017 - December 2019 period. Variables assessed in this study were age, sex, address of residence, infected side, perforation surface area, CT-scan, culture, surgical findings, graft type and antibiotic therapy, post tympanoplasty tympanic membrane perforation condition, audiometry results before and after undergoing tympanoplasty. Data were analyzed using SPSS version 20 for Windows.Results: Most of the respondents were male (53.3%), aged 46 - 55 years (26.7%), and living in Denpasar (30.0%). Based on the ear side, the most infected were unilateral (53.3%) and the subtotal perforation surface area (78.3%). No visible abnormalities (40.0%) were the most cases on the CT-Scan, following by the Pseudomonas aeruginosa (21.7%) infection and surgical findings in the form of tympanic membrane perforation only (55.0%). Based on the 3 months post tympanoplasty condition, it was found that the perforation had closed (83.3%), normal audiometric results (38.3%), and a degree of improvement in the hearing threshold after undergoing tympanoplasty was found to be mostly 5-10 dB (48.3%).Conclusion: CSOM patients who underwent tympanoplasty surgery were mostly men, aged 46-55 years, unilateral, subtotal perforation, and no CT scan abnormalities. In comparison, the membrane perforation condition 3 months post tympanoplasty was closed, mild deafness before tympanoplasty, normal degree of deafness after tympanoplasty, and the average mean hearing threshold improvement was 5 - 10 dB.
