Summary

Sudden hearing loss (SHL) can be severe, affecting one or both ears, and often accompanied by tinnitus and vestibular issues. Echocardiography revealed cardiac abnormalities in most patients, suggesting a potential link.

Area of Science:

  • Otolaryngology
  • Cardiology
  • Internal Medicine

Context:

  • Sudden hearing loss (SHL) is an otologic emergency requiring prompt evaluation.
  • The underlying etiology of SHL is often idiopathic, necessitating investigation into potential systemic associations.
  • This study investigated cardiac findings in patients presenting with SHL.

Purpose:

  • To evaluate the clinical characteristics and audiological findings in patients with sudden hearing loss.
  • To assess the prevalence of cardiac abnormalities, specifically mitral valve prolapse and left ventricular dysfunction, in this patient cohort.

Summary:

  • Twelve patients (median age 49) with severe to profound SHL were evaluated between 1993-1994.
  • Twenty-five percent had bilateral involvement, and 33% experienced total deafness in one ear.

  • Vestibular symptoms (75%) and tinnitus (67%) were common. Echocardiography identified mitral valve prolapse in 67% and ischemic left ventricular dysfunction in one patient.

    • Impact:

    • Highlights a potential association between sudden hearing loss and cardiac conditions, particularly mitral valve prolapse.
    • Suggests that cardiac evaluation may be warranted in select patients presenting with sudden hearing loss.
    • Underscores the importance of a multidisciplinary approach in managing sudden hearing loss.
