Sudden Sensorineural Hearing Loss in Patient Incidental to Treatment With Hyaluronic Acid Filler.

ABSTRACT

Hyaluronic acid fillers comprise a major component of aesthetic practice with few serious adverse effects. Hearing loss has not been previously associated with hyaluronic acid filler. The authors describe a case in which a patient developed sudden sensorineural hearing loss 1 day after filler injection into the nasolabial folds. Audiogram showed moderately severe sensorineural loss, and MRI revealed no abnormalities. Despite transtympanic steroid injections and hyperbaric oxygen therapy, the hearing loss persists at the time of writing. Although no causal relationships can be drawn from this case alone, this case serves to reinforce the importance of continued vigilance for future occurrences to minimize the potential risk of this serious adverse event.
