Preoperative and postoperative audiological outcomes in 83 patients with tympanic membrane perforation

According to the site of perforation, classified using the Morris quadrant system, patients were categorized into four groups: anteroinferior, anterosuperior, posteroinferior, and posterosuperior.③The relative area of tympanic membrane perforation (RAp) was calculated as: RAp = (perforation area / total tympanic membrane area) × 100%. Based on the RAp values, patients were categorized into four groups: micro-perforation (RAp ≤ 2.5%), small perforation (2.5% < RAp ≤ 12.5%), medium perforation (12.5% < RAp ≤ 35.0%), and large perforation (RAp > 35.0%).Note：This dataset is used exclusively for the research purposes of our study group, and all personally identifiable information has been anonymized.
