The bone conduction threshold pattern may help to estimate the pathology underlying conductive hearing loss.

ABSTRACT: Air conduction and bone conduction thresholds in audiograms provide clinically useful information. However, whether bone conduction audiograms can help distinguish between different conductive hearing disorders remains unestablished. This retrospective case-control study included patients with hearing loss (surgically-confirmed ossicular sclerosis, ossicular discontinuity or tympanic membrane perforation) and a group of people with normal hearing (Jikei University School of Medicine, Tokyo, Japan). Data were collected between November 30, 2017 and December 30, 2022. Bone conduction threshold patterns (pure tone audiometry) were compared between groups. All experiments were performed in accordance with the relevant guidelines and regulations. Ossicular fixation was associated with a dip at
