Area of Science:

  • Otolaryngology
  • Neurosurgery
  • Surgical Innovation

Background:

  • Labyrinthine fistulas complicate approximately 5% of cholesteatoma surgeries.
  • Management strategies for cholesteatoma with labyrinthine fistula remain controversial.
  • Preoperative symptoms and diagnostic test accuracy can be variable.

Purpose of the Study:

  • To assess the preoperative presentation and surgical outcomes of patients with cholesteatoma and labyrinthine fistula.
  • To introduce a fistula classification scheme for standardized reporting.
  • To evaluate the impact of corticosteroids on surgical outcomes.

Main Methods:

  • Retrospective analysis of 37 patients undergoing surgery for cholesteatoma with labyrinthine fistula.
  • Surgical technique involved matrix removal and labyrinth reconstruction using bone dust, fibrin glue, and perichondrium.
  • A fistula classification scheme was developed and applied.
  • Corticosteroids were incorporated into the management protocol for recent cases.

Main Results:

  • Sensorineural hearing loss and vertigo were absent in over 30% of patients preoperatively.
  • The fistula test was positive in only 32% of cases.
  • Corticosteroids demonstrated a beneficial effect on postoperative outcomes, particularly in cases with membranous labyrinth injury or perilymphatic fistula.

Conclusions:

  • Cholesteatoma with labyrinthine fistula presents diagnostic challenges with variable preoperative symptoms and test results.
  • A standardized fistula classification aids in reporting and outcome assessment.
  • Corticosteroid therapy appears to improve outcomes in specific types of labyrinthine fistula injuries following cholesteatoma surgery.
