Summary

Endoscopic stapes surgery offers comparable hearing outcomes to microscopic surgery with less pain and reduced drilling. This minimally invasive technique is ideal for certain ear canal anatomies but requires surgeon expertise.

Area of Science:

  • Otolaryngology
  • Minimally Invasive Surgery
  • Surgical Techniques

Background:

  • Stapes surgery is a common procedure for otosclerosis and congenital stapedial fixation.
  • Conventional microscopic stapes surgery involves specific instrumentation and approaches.
  • Evaluating novel techniques like endoscopic stapes surgery is crucial for improving patient outcomes.

Purpose of the Study:

  • To compare the safety and invasiveness of endoscopic stapes surgery versus conventional microscopic stapes surgery.
  • To assess key surgical and patient-reported outcomes between the two techniques.

Main Methods:

  • A retrospective study comparing 15 patients undergoing endoscopic stapes surgery with 41 patients undergoing microscopic stapes surgery.
  • Procedures were similar, with endoscopic surgery avoiding skin incisions when possible.

  • Outcomes analyzed included operating time, hearing results, complications, pain, and drilling extent.

    • Main Results:

    • No significant differences in operating time or postoperative hearing between endoscopic and microscopic groups.
    • Endoscopic stapes surgery demonstrated significantly less postoperative pain and milder dizziness.
    • Reduced drilling in the posterosuperior external auditory canal was observed with the endoscopic approach.

    Conclusions:

    • Endoscopic stapes surgery is a viable and potentially less invasive alternative for stapedial disease, especially in narrow or curved ear canals.
    • The technique offers educational benefits due to enhanced visualization for the entire surgical team.
    • Expertise is essential for endoscopic stapes surgery due to the need for one-handed manipulation and lack of stereoscopic vision.
