Abstract

Background: Chronic otitis media with tympanic membrane perforation accompanied by myringosclerosis is a common condition that causes prolonged hearing loss and increases the difficulty of tympanoplasty. Evaluating the disease characteristics and treatment outcomes helps in selecting appropriate surgical indications and prognostic assessment. Objectives: To describe the clinical and paraclinical characteristics and to evaluate the outcomes of endoscopic tympanoplasty for perforated tympanic membrane with myringosclerosis in patients with chronic otitis media at Can Tho ENT Hospital during 2025–2026. Materials and methods: This was a prospective crosssectional descriptive study with clinical intervention and no control group conducted on 41 patients who underwent endoscopic tympanoplasty from April 2025 to April 2026. Variables included clinical characteristics, lesion morphology, and anatomical and hearing functional outcomes before and after surgery. Results: The mean age was 48.8 ± 12.05 years, with female predominance. Common symptoms included tinnitus, hearing loss, and otorrhea; the mean disease duration was 44 months. Central perforations and medium-sized perforations were predominant; myringosclerosis was mainly grade II and commonly located in the posterosuperior quadrant. The tympanic membrane closure rate reached 97.56% after 3 months (p < 0.001). Hearing improved significantly, with marked reductions in PTA and ABG (p < 0.001). The size of the sclerotic plaque correlated with operative time; small-to-medium perforations had better closure outcomes than large perforations. Conclusions: Endoscopic tympanoplasty is a safe and effective method that restores tympanic membrane integrity and improves hearing function; perforation size and the degree of myringosclerosis have prognostic value for surgical outcomes.
