Sequential cholesteatoma surgery offers excellent hearing outcomes. Techniques like exclusively transcanal (ETC) and combined transcanal-transmastoidal (TCM) surgery yield better results than canal wall down (CWD) procedures, with partial ossicular replacement prostheses (PORP) showing superior outcomes.

Area of Science:

  • Otolaryngology
  • Audiology
  • Surgical Innovation

Background:

  • Cholesteatoma surgery aims to eradicate disease and preserve/restore hearing.
  • Different surgical techniques and ossicular reconstruction methods impact audiological outcomes.

Purpose of the Study:

  • To evaluate hearing results after sequential cholesteatoma surgery using exclusively transcanal (ETC), combined transcanal-transmastoidal (TCM), and canal wall down (CWD) techniques.
  • To analyze the effect of partial ossicular replacement prostheses (PORP) versus total ossicular replacement prostheses (TORP) on hearing outcomes.

Main Methods:

  • Retrospective case review of 376 cholesteatoma surgeries (2007-2009) with 92 ears examined postoperatively.
  • Comparison of pre- and postoperative air-bone gap (ABG) and air conduction thresholds (AC) for 0.5-3 kHz.

  • Stratification by surgical technique (ETC, TCM, CWD) and ossiculoplasty (PORP, TORP).

    • Main Results:

    • Overall mean ABG improved from 25.3 dB to 19.8 dB (5.4 dB closure).
    • Canal wall down (CWD) surgery resulted in worse postoperative ABG (23.5 dB) compared to ETC (17.3 dB) and TCM (19.4 dB).
    • Significant ABG closure was achieved with ETC (6.8 dB) and TCM (6.5 dB), but not CWD (2.1 dB).
    • Partial ossicular replacement prostheses (PORP) yielded better postoperative ABG (19.0 dB) than total ossicular replacement prostheses (TORP) (24.1 dB).
    • Both PORP (4.7 dB) and TORP (10.4 dB) showed significant hearing gain.

    Conclusions:

    • Sequential cholesteatoma surgery, particularly ETC and TCM techniques, can achieve excellent postoperative hearing outcomes.
    • An intact posterior canal wall and stapes suprastructure are crucial predictors of superior hearing results.
    • Audiological outcomes are influenced by surgical technique, prosthetic choice, and concurrent middle ear pathology.
