The moderating effect of personality traits on acute tinnitus sensation in idiopathic sudden sensorineural hearing loss.

BACKGROUND

People may experience tinnitus after sudden hearing impairment. The details of the relationship between tinnitus improvement and hearing recovery are still unclear. Personality traits may play a role in the modulation of tinnitus sensation. We investigated the moderating effect of personality traits on pretreatment and posttreatment tinnitus sensation in patients with idiopathic sudden sensorineural hearing loss (ISSHL).

METHODS

This prospective longitudinal study enrolled 33 patients diagnosed with unilateral ISSHL and acute tinnitus in 2018-2019 at one institute. Clinical data were collected before and after treatment, including results of pure-tone audiometry (PTA), the Clinical Tinnitus Questionnaire (CTQ), the Tinnitus Handicap Inventory (THI), tinnitus loudness and annoyance (Visual Analog Scale; VAS), the Hospital Anxiety and Depression Scale (HADS), and the Big Five Inventory (BFI)-44.

RESULTS

Eighteen men and 15 women with an average age of 48.3 ± 15.8 years were enrolled. The pretreatment hearing threshold and THI score were 58.0 ± 27.4 dB HL and 42.9 ± 26.2 (range: 0-88), respectively; the posttreatment values were 39.8 ± 22.4 dB HL and 20.7 ± 22.5 (range: 0-64), respectively. There were significant differences between pretreatment and posttreatment hearing thresholds as well as THI, VAS, and HADS scores (p < 0.001) but not BFI-44 results. Neuroticism and openness had significant positive and negative correlations, respectively, with acute tinnitus stress before treatment (r = 0.561, p = 0.001; r = -0.359, p = 0.040). After 3 months of follow-up, all patients were analyzed separately by dividing them into recovery (n = 16) and nonrecovery groups (n = 14) according to their hearing improvement status by Siegel's criteria. Neuroticism showed a significant moderating effect on acute tinnitus sensation in the ISSHL recovery group (p < 0.001) but not in the nonrecovery group (p = 0.106).

CONCLUSION

Neuroticism and openness may affect acute tinnitus stress in ISSHL patients. Practitioners should consider personality traits when managing ISSHL patients with bothersome tinnitus.
