Spontaneous cerebrospinal fluid leaks from the temporal bone are often indicated by ear fullness and hearing loss. Transmastoid surgery is favored for its simplicity and safety in treating these leaks.

Area of Science:

  • Neurosurgery
  • Otolaryngology

Background:

  • Spontaneous cerebrospinal fluid (CSF) leaks originating from the temporal bone are rare but significant otoneurological conditions.
  • Understanding the etiology, presentation, and optimal management is crucial for patient outcomes.

Observation:

  • Eight new cases of temporal bone CSF leaks are presented, alongside a review of 33 prior cases.
  • Common symptoms include unilateral ear fullness and mild hearing loss.
  • Profuse clear otorrhea after myringotomy is a highly indicative sign.

Findings:

  • High-resolution computed tomography (HRCT), magnetic resonance imaging (MRI), and contrast cisternography aid in diagnosis.
  • Both transmastoid and combined transmastoid/middle fossa approaches are equally effective for surgical repair.

  • The transmastoid approach is preferred initially due to its simplicity, safety, and comprehensive visualization.

    • Implications:

    • Accurate diagnosis and timely surgical intervention are essential for managing temporal bone CSF leaks.
    • The transmastoid approach offers a safe and effective primary surgical option.
    • Further research can refine diagnostic strategies and surgical techniques for these complex cases.
