Summary

Sudden sensorineural hearing loss is an otologic emergency. A new HEAR staging system (Hearing threshold, Elapsed time, Audiogram shape, Related vestibular symptoms) aids in classification, and potential treatments like antiviral drugs are explored.

Area of Science:

  • Otolaryngology
  • Neurology
  • Emergency Medicine

Background:

  • Idiopathic sudden sensorineural hearing loss (ISSNHL) is a critical otologic emergency with unclear etiology.
  • Effective diagnostic and therapeutic strategies for ISSNHL are limited, necessitating further research.

Purpose of the Study:

  • To review recent clinical literature on ISSNHL.
  • To introduce a novel clinical staging system for ISSNHL.
  • To explore potential, underexplored therapeutic interventions for ISSNHL.

Main Methods:

  • Literature review of recent clinical studies on ISSNHL.
  • Development and presentation of the HEAR clinical staging system.
  • Identification and discussion of potential treatments including antiviral drugs, rheologic agents, and free radical scavengers.

Main Results:

  • The HEAR staging system integrates hearing threshold, elapsed time from onset, audiogram shape, and related vestibular symptoms.
  • Antiviral drugs, rheologic agents, and free radical scavengers are identified as promising, yet insufficiently explored, treatment options.

Conclusions:

  • The HEAR staging system offers a structured approach to classifying ISSNHL.
  • Further investigation into novel therapeutic agents is warranted for improved ISSNHL management.
