Diagnosing perilymph fistula (PLF) is challenging due to varied symptoms. Meticulous clinical history and repeated fistula tests are crucial for accurate diagnosis of this inner ear condition.

Area of Science:

  • Otolaryngology
  • Neurosurgery
  • Audiology

Background:

  • Perilymph fistula (PLF) diagnosis remains challenging despite its prevalence.
  • Exploratory tympanotomy is currently the definitive diagnostic method for PLF.
  • Early PLF diagnosis relies heavily on patient history and clinical examinations.

Purpose of the Study:

  • To investigate the clinical features of perilymph fistula (PLF).
  • To identify factors aiding in earlier and more accurate PLF diagnosis.
  • To evaluate the reliability of classic diagnostic procedures for PLF.

Main Methods:

  • Retrospective analysis of 44 patients diagnosed with PLF between 1983 and 1998.
  • Investigation of clinical symptoms, predisposing factors, and basic test results.

  • Assessment of therapeutic outcomes following PLF closure.

    • Main Results:

    • Common symptoms include hearing loss (93%), vertigo/dizziness (91%), and tinnitus (76%).
    • Predisposing factors were identified in about half of the patients; others lacked clear triggers.
    • Subjective fistula signs were present in 71% of patients, with 80% experiencing symptom improvement after PLF closure.

    Conclusions:

    • Varied clinical presentations of PLF complicate diagnosis.
    • Meticulous clinical history taking is essential for accurate PLF diagnosis.
    • Repeated fistula tests and close follow-up improve diagnostic accuracy for PLF.
