Idiopathic Sensorineural Hearing Loss

Idiopathic Sensorineural Hearing Loss

 

Idiopathic Sensorineural Hearing Loss for professionals

 

The UHMS define ISSHL as greater than 30db occurring within 3 days and over at least 3 contiguous frequencies.

Individuals commonly report one or a combination of the following clinically,

  • Sudden unilateral hearing loss
  • Tinnitus
  • Fullness in the affected ear
  • Vertigo

 

It is well understood that the cause of ISSHL is uncertain and many different aetiologies and pathological theories have been cited. However, it is known that the cochlea has a high metabolism and poor vascularity. Thus in theory the use of HBO will improve oxygenation of the organ. There have been a small number of trials to investigate whether this increase in oxygenation will improve outcomes.

This was first explored as a treatment options in 1985 by Pilgramm. His reports on 37 patients showed significant benefits to those who had acute hearing loss alongside standard medical treatment at the time. This was further supported in 1995 by Hoffman.

The most significant of recent studies was performed by Topuz in 2004. An average of 50.7dB improvement in individuals with severe hearing loss treated with HBO in addition to Medical therapy (including steroids) was seen across all frequency ranges except 2000Hz.

The latest Cochrane review has suggested that the use of HBO within 2 weeks of onset of symptoms is a worthwhile treatment option.
