Endoscopic techniques for second-look mastoidectomy in cholesteatoma surgery show promise, with no false-negative results. However, endoscopes may underestimate recurrence size, requiring careful consideration of their use.

Area of Science:

  • Otolaryngology
  • Surgical Innovation

Background:

  • Intact canal wall mastoidectomy for cholesteatoma often necessitates a second-look procedure to check for residual disease and perform ossicular reconstruction.
  • Endoscopic techniques offer potential morbidity reduction but also present unique challenges and concerns.

Purpose of the Study:

  • To evaluate the efficacy and safety of endoscope-assisted second-stage tympanomastoidectomy for cholesteatoma.
  • To present experience, indications, and precautions for using endoscopes in second-look mastoidectomy procedures.

Main Methods:

  • Twenty-five consecutive second-look mastoidectomy procedures were performed between July 1994 and July 1996.
  • Endoscopes were utilized in 19 cases; their use was avoided or terminated in others due to anatomical challenges, poor exposure, or bleeding.

  • Thirteen cases underwent a prospective comparison of an exclusively endoscopic approach followed by a conventional open second look.

    • Main Results:

    • Endoscopy was abandoned in one of the 13 prospectively explored cases.
    • No false-negative results were observed with endoscopic examination.
    • Endoscopes underestimated the size of cholesteatoma recurrence in one instance.

    Conclusions:

    • Endoscope-assisted second-stage tympanomastoidectomy is a viable option for cholesteatoma management.
    • While effective in detecting residual disease, potential underestimation of recurrence size necessitates careful surgical judgment and technique.
    • Further experience and defined indications are crucial for optimizing the use of endoscopy in these procedures.
