Abstract

Background: Chronic otitis media is defined as any structural change in the middle ear system associated with permanent perforation of the eardrum for a period greater than 3 months. 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. Objectives: To describe the clinical and subclinical characteristics and to assess the results of endoscopic tympanoplasty with mixed grafts on patients with chronic otitis and tympanic membrane perforation. Materials and methods: A descriptive cross-sectional study, prospective design with clinical interventions on 31 cases of chronic otitis media with tympanic perforation were doing endoscopic tympanoplasty using mixed grafts at 199 Hospital from January 2025 to September 2025. Results: There were 31 cases included in the study, of which 18 were female and 13 were male. The age group from 31 to 45 years old accounted for the highest rate of 86.4%; the average age of the study group was 43,62 ± 12,5 years old. The rate of main clinical symptoms were hearing loss (100,0%), tinitus (89,2%). Endoscopic features include: location of tympanic membrane perforation center (61,3%), medium hole (45,1%). The overall tympanic membrane's healing rate after 3 months of surgery was 83,9%. The average level of hearing loss before surgery was 40,4±8,3 dB, the average hearing improved after 3 months to 32,2±9,7 dB. Conclusions: Chronic otitis media with main symptoms is tinitus and hearing loss. Evaluation of treatment results: the rate of atrial healing after 3 months was 83,9%. Functionally, mean hearing improvement from 40,4±8,3 dB to 32,2±9,7 dB 3 months after surgery.
