Tympanoplasty surgery for perforated eardrums achieved an 89.2% hearing improvement rate. Surgical success depends on addressing ossicular chain mobility issues and middle ear lesions, guiding preoperative planning.

Area of Science:

  • Otolaryngology
  • Surgical Pathology
  • Audiology

Background:

  • Tympanic membrane perforations present diverse pathologies, impacting ossicular chain mobility.
  • Sclerotic and inflammatory middle ear lesions often complicate perforations.
  • Surgical intervention requires a systematic approach to address these complex pathologies.

Purpose of the Study:

  • To evaluate the postoperative outcomes of tympanoplasty in patients with tympanic membrane perforations.
  • To identify key surgical checkpoints and the order of lesion removal for improving ossicular chain mobility.
  • To correlate preoperative findings with surgical success and predict operative requirements.

Main Methods:

  • Retrospective analysis of 37 tympanoplasty surgeries performed between June 1996 and May 1999.

  • Systematic identification and removal of lesions affecting ossicular chain mobility.
  • Assessment of hearing improvement using air and bone conduction thresholds.

    • Main Results:

    • Overall hearing improvement success rate of 89.2% was achieved.
    • Lesions were removed sequentially: calcified tympanic membrane, malleus handle tip, anterior tympanic spur, and epitympanum.
    • Residual conductive impairment varied based on the site and extent of tympanic and middle ear lesions.

    Conclusions:

    • Tympanoplasty demonstrates high success rates in improving hearing for perforated eardrums.
    • The specific site and range of middle ear pathology influence postoperative conductive impairment.
    • Preoperative assessment of lesions is crucial for predicting the optimal surgical approach and expected outcomes.
