Area of Science:

  • Otolaryngology
  • Surgical Innovation
  • Reconstructive Surgery

Background:

  • Open radical cavities in the ear present complex surgical challenges.
  • Traditional methods have limitations in achieving complete eradication and preventing recurrence.
  • Advancements in surgical techniques and materials are crucial for improving outcomes.

Purpose of the Study:

  • To review the evolution of surgical techniques for eliminating open radical cavities.
  • To present a personal series of 240 cases utilizing various obliteration and reconstruction methods.
  • To evaluate the efficacy of these techniques in preventing residual cholesteatoma and improving hearing.

Main Methods:

  • Detailed review of surgical approaches: obliteration, reconstruction, and ablation.

  • Application of porous hydroxylapatite ceramic implants and Grote implants for defect repair.
  • Utilized middle temporal flap for enhanced canal wall vascularity.
  • Employed staged surgery and cartilage-perichondrium grafts for cholesteatoma prevention.
  • Performed ossiculoplasty using various columella types and Spanner assemblies.

    • Main Results:

    • Improved canal repair success rates with the middle temporal flap.
    • Staged surgery virtually abolished recurrent cholesteatoma.
    • Hearing improvement: 33% closed air-bone gap to within 10 dB, 66% to within 20 dB (since 1990).
    • SPITE (surgical, prosthetic, infection, tissues, and eustachian) studies indicated reduced pathology with staged surgery.

    Conclusions:

    • Elimination surgery, particularly with staged approaches and advanced materials, offers permanent relief for open radical cavities in most cases.
    • Technological advancements have significantly improved hearing outcomes and disease control.
    • Staged surgery is a key factor in reducing pathology and preventing recurrence.
