Background:
Hearing loss caused by middle ear malformations is treated by tympanoplasty to reconstruct the acoustic conduction system. The mobility of the ossicles plays a crucial role in postoperative success. However, identifying the location of ossicular malformation based solely on preoperative audiograms is challenging due to the complex relationship between fixation location, deformity levels, and ossicular mobility.
Methods:
Middle ear finite element models for simulating ossicular malformations were created, and the results were compared with the actual preoperative audiograms.
Results:
This approach objectively diagnosed ossicular fixation and disarticulation, bypassing traditional criteria reliant on physician examination or imaging.
Conclusion:
This study suggests that future research should focus on developing a diagnostic framework utilizing large-scale data.
