Intraoperative otoendoscopy aids cholesteatoma surgery by improving visualization and enabling surgeons to preserve the canal wall. Its use led to better disease control and reduced residual cholesteatoma, influencing surgical decisions.

Area of Science:

  • Otolaryngology
  • Surgical Technology
  • Medical Imaging

Background:

  • Cholesteatoma surgery aims for complete eradication.
  • Traditional microscopy may have limitations in visualizing hidden disease areas.
  • Intraoperative decision-making impacts surgical outcomes.

Purpose of the Study:

  • To evaluate intraoperative otoendoscopy's influence on surgical decision-making in cholesteatoma surgery.
  • To assess the efficacy of endoscopy in detecting residual cholesteatoma matrix.
  • To compare outcomes between canal wall-up (CWU) and canal wall-down (CWD) techniques with and without endoscopy.

Main Methods:

  • 82 ears with acquired cholesteatoma were analyzed.
  • Four groups were formed based on surgical technique (CWU/CWD) and endoscopy use.

  • Endoscopy served as a complementary tool to microscopy during surgery.

    • Main Results:

    • Intraoperative cholesteatoma matrix remnants were detected by endoscopy, particularly in the sinus tympani.
    • Residual cholesteatoma was significantly higher in the CWU group (25%) versus the CWD group (5%) when endoscopy was not used.
    • Endoscopy use correlated with higher detection rates of residual disease in CWU (50%) vs CWD (30%) groups.

    Conclusions:

    • Intraoperative otoendoscopy enhances surgeon control and confidence in cholesteatoma removal.
    • Endoscopy facilitates better disease eradication, potentially allowing for more conservative surgical approaches like canal wall preservation.
    • The use of endoscopy can positively influence surgical decision-making, leading to improved patient outcomes.
