Clinical Feature and Prognosis of Sudden Sensorineural Hearing Loss With Rheumatoid Arthritis

Recent publications reported that patients with rheumatoid arthritis (RA) experience an increased risk of suffering sudden sensorineural hearing loss (SSNHL), however, these cases are poorly understood. This study aims to explore the clinical presentations and hearing recovery of SSNHL patients with RA.

Retrospective study.

Tertiary medical center.

Forty-seven SSNHL patients with RA (RA group) and 431 SSNHL patients without RA (non-RA group) were recruited between April 2015 and June 2019.

In the non-RA group, all patients were administrated with oral steroids. In the RA group, 21 patients were treated with oral steroid (OS group) and 26 patients were administrated with intratympanic steroids plus oral steroids (IS+OS group).

We explored the clinical features and hearing recovery of SSNHL patients with RA in comparison with patients without RA, we also evaluated the therapeutic effect of combined steroids in SSNHL patients with RA.

RA group had higher initial hearing loss level (mean 68.5 dB), final hearing threshold (mean 52.3 dB), the rates of profound hearing loss (48.9%), and no recovery (48.9%) than non-RA group (mean 55.1 dB, mean 34.8 dB, 32.9 and 27.6%, all p < 0.05), however, had lower hearing gains (mean 16.1 dB) and the rate of partial recovery (12.8%) than non-RA group (mean 20.3 dB and 28.8%, all p < 0.05). Furthermore, IS+OS group had higher hearing gains (mean 21.1 dB) and lower rate of no recovery (30.8%) than in the OS group (mean 10.0 dB and 71.4%, all p < 0.05).

SSNHL patients with RA experienced severe hearing loss and had poor hearing prognosis. IS+OS provide better hearing recovery than OS for this population.
