Summary

Sudden hearing loss patients with vertigo experienced poorer high-frequency hearing recovery. This suggests vertigo is linked to worse outcomes in sudden sensorineural hearing loss.

Area of Science:

  • Otolaryngology
  • Audiology
  • Neurology

Background:

  • Unilateral sudden hearing loss (USH L) is an otologic emergency requiring prompt diagnosis and management.
  • The presence of vertigo in USHL patients is a significant clinical sign, but its prognostic value is debated.
  • Understanding factors influencing hearing recovery in USHL is crucial for patient counseling and treatment strategies.

Purpose of the Study:

  • To investigate the relationship between vertigo and the characteristics of hearing loss in patients with unilateral sudden hearing loss.
  • To evaluate the impact of vertigo on hearing recovery outcomes in patients with USHL.
  • To correlate audiometric findings (severity and pattern) with the presence of vertigo in USHL.

Main Methods:

  • Retrospective analysis of 87 patients diagnosed with unilateral sudden hearing loss.

  • Patients were categorized into two groups: those with and without accompanying vertigo.
  • Audiometric evaluations assessed initial hearing loss severity and tonal audiogram patterns; hearing recovery was monitored.

    • Main Results:

    • Vertigo was present in 25% of the investigated USHL patients.
    • Vertigo was more frequently observed in patients with severe high-frequency hearing loss.
    • Patients experiencing vertigo showed significantly poorer high-frequency hearing recovery compared to those without vertigo, despite similar initial hearing loss.

    Conclusions:

    • Vertigo is a common accompanying symptom in unilateral sudden hearing loss, particularly associated with severe high-frequency deficits.
    • The presence of vertigo indicates a poorer prognosis for high-frequency hearing recovery in USHL patients.
    • Audiological assessment and consideration of vertigo are essential for predicting outcomes in sudden sensorineural hearing loss.
