Abstract

Background: Tympanoplasty is the surgical procedure performed to repair a perforated tympanic membrane. The goal of this surgical procedure is not only to close the perforation but also to improve hearing. The endoscopic approach provides a much larger field of view than the microscopic approach. Therefore, endoscopic tympanoplasty implementations are becoming increasingly popular. Objectives: Describing the clinical, subclinical characteristicc and assessing the results and figered out some relating of the endoscopic tympanoplasty in patients having chronic otitis media with tympanic perforation. Materials and methods: A descriptive crosssectional study, prospective design with clinical interventions on 71 cases of chronic otitis media with tympanic perforation were doing endoscopic tympanoplasty by using underlay technique at Can Tho General Hospital and Can Tho University of Medical and Pharmacy Hospital in 2019-2021. Results: There were 71 cases included in the study, of which 52 were female and 19 were male. The age group from 16 to 50 years old accounted for the highest rate of 67.6%; the remaining group of patients over 50 years old accounted for 32.4%, the average age of the study group was 44.27 ± 13.4 years old. The rate of healing of the tympanic membrane after 1 month was 94.4% and after 3 months, the healing rate increased to 97.2%. The average level of hearing loss before surgery was 40.66 ± 12.44 dB, the average hearing improved after 3 months to 27.62 ± 9.17 dB. Conclusion: Up to 97.2% of patients have symptoms of persistent drainage from the middle ear. The rate of healing of the tympanic membrane after 1 month was 94.4% and after 3 months, the healing rate increased to 97.2%. After 3 months of tympanoplasty surgery, pure tone average improved from 40.66dB ± 12.44 to 27.62 ± 9.17 dB.
