Methods: Forty patients with acne vulgaris were included in this study. Nine patients were excluded from the study because of inconsistent follow-up. The hearing of each participant was tested with pure tone audiometry and transient evoked autoacoustic emissions before and two and four weeks after treatment with isotretinoin (0.3-0.6 mg/kg/day) in the remaining 31 patients (62 ears). Results: Th e di ff erences between the mean values of the pre- treatment and post-treatment pure tone hearing thresholds at 1000, 2000, 4000 and 6000 Hz frequencies were statistically signi fi cant (p< 0.05), but there was no signi fi cant di ff erence between the pretreatment and post- treatment values at 250 and 500 Hz frequencies (p> 0.05). The difference between the pre-treatment and post-treatment signal-noise ratio values of the transient evoked autoacoustic emissions was not significantly different (p> 0.05). Conclusion: Our results suggest that the use of isotretinoin may cause bilateral hearing threshold changes. Further animal and human studies are required to investigate and characterize isotretinoin- induced neurophysiological alterations in hearing.eninfo:eu-repo/semantics/closedAccess[No Keyword]The effects of oral isotretinoin (13-Cis retinoic acid) on the inner ear: A prospective clinical studyThe effects of oral isotretinoin (13-Cis retinoic acid) on the inner ear: A prospective clinical studyArticle372E102E107WOS:0003342965000072-s2.0-8489865987324690417Q2Q4
