Dynamics of sensorineural hearing loss after head trauma

Otol Neurotol. 2002 May;23(3):312-5. doi: 10.1097/00129492-200205000-00014.


Objective: To estimate the temporal endpoint of permanent sensorineural hearing loss after head trauma.

Study design: Retrospective observational case study.

Patients: In patients with sensorineural hearing loss caused by head trauma, 1,741 ears were studied.

Main outcome measure: A follow-up survey of audiograms in patients with sensorineural hearing loss after head trauma was performed for up to 4 years from the date of injury. Each patient's audiograms were compared according to a severity score that specifically classified hearing loss that was associated with acoustic trauma.

Results: Either improvement or deterioration of the early posttrauma hearing loss occurred during the first year after head trauma. Thereafter, hearing levels could be expected to remain stationary.

Conclusion: Fluctuation in hearing after head trauma may take place within the first year after trauma, after which the associated hearing loss should be considered to be stabilized.
