Area of Science:

  • Otolaryngology
  • Neurosurgery
  • Skull Base Surgery

Background:

  • Petrous bone cholesteatoma (PBC) is an epidermoid cyst in the temporal bone's petrous portion.
  • Management of PBC has advanced with improved imaging and surgical techniques.

Purpose of the Study:

  • To evaluate the clinical and audiological outcomes of petrous bone cholesteatoma management.
  • To assess the effectiveness of tailored surgical approaches and postoperative monitoring.

Main Methods:

  • An ambispective descriptive study of 10 patients diagnosed with PBC (2021-2024).
  • Clinical, audiological, and radiological evaluations were performed.
  • Surgical approaches (subtotal petrosectomy, radical mastoidectomy, endoscopy) were selected based on disease characteristics.

Main Results:

  • Acquired cholesteatoma was predominant (8/10 patients).
  • Hearing loss and facial palsy were common presenting symptoms.
  • Surgical interventions led to improved facial nerve function with no recurrence during follow-up.

Conclusions:

  • Tailored management considering lesion extent and functional outcomes is crucial for PBC.
  • Aggressive surgical techniques may be needed for extensive disease, prioritizing hearing and facial nerve preservation.
  • Endoscopic approaches show promise for petrous apex involvement, and postoperative monitoring ensures long-term remission.
