Persistent traumatic perilymph fistulas.

M E Glasscock, K X McKennan, S C Levine

    The Laryngoscope
    |July 1, 1987
    PubMed
    Summary
    This summary is machine-generated.

    Perilymph fistulas, often resulting from ear trauma, were identified in 24% of explored ears. Surgical repair significantly reduces vestibular symptoms and may improve hearing, even when performed months after injury.

    Area of Science:

    • Otolaryngology
    • Neurosurgery
    • Trauma Surgery

    Background:

    • Perilymph fistulas are abnormal openings between the middle and inner ear.
    • Traumatic ear injuries can cause perilymph fistulas, leading to auditory and vestibular dysfunction.
    • Diagnosis and timely management are crucial for preserving hearing and balance.

    Purpose of the Study:

    • To investigate the incidence and outcomes of perilymph fistulas following ear trauma.
    • To evaluate the effectiveness of surgical repair on vestibular and auditory symptoms.
    • To assess the complication rate associated with diagnostic surgical exploration.

    Main Methods:

    • Exploration of 34 ears to diagnose perilymph fistulas post-trauma.
    • Identification of fistula presence and characteristics.

    Related Experiment Videos

  • Assessment of surgical repair outcomes, including symptom reduction and hearing improvement.

    • Main Results:

    • Perilymph fistulas were confirmed in 8 ears (24%) an average of 7.5 months post-injury.
    • Surgical repair led to significant reduction in vestibular symptoms.
    • Improvement in low and middle frequency sensorineural hearing was observed post-repair.
    • Complications from negative surgical explorations were infrequent.

    Conclusions:

    • Perilymph fistulas are a notable complication of ear trauma, often presenting late.
    • Surgical intervention for perilymph fistulas is effective in alleviating vestibular issues and potentially improving hearing.
    • Surgical exploration for suspected perilymph fistulas carries a low risk of complications.
