About the trial
What the trial wants to find out
The goal of this observational case-control study is to evaluate the relationship between temporal bone computed tomography (CT) findings, bone mineral density (BMD), and audiological parameters in adults diagnosed with otosclerosis. The main questions it aims to answer are:
Read full original descriptionShow less
Is there a correlation between temporal bone CT density values and the severity of hearing loss in otosclerosis? Do bone mineral density and serum vitamin D levels differ between otosclerosis patients and individuals without otosclerosis? Researchers will compare patients diagnosed with otosclerosis to a control group without otosclerosis to determine if CT-based density variations are associated with disease severity and systemic bone metabolism markers.
Participants who have already had a temporal bone CT scan as part of their routine clinical evaluation will undergo:
Bone mineral density (BMD) assessment via dual-energy X-ray absorptiometry (DEXA) Serum vitamin D level measurement Audiological testing, including pure tone audiometry and speech discrimination tests This study aims to improve the diagnostic and prognostic understanding of otosclerosis by integrating imaging, metabolic, and audiological data.
The 2 groups in the trial
- Otosclerosis Group
Participants diagnosed with otosclerosis based on clinical and audiological criteria. These individuals have undergone or are planned for stapedectomy or stapedotomy surgery. High-resolution CT scans and bone metabolism markers will be analyzed to assess correlations with disease severity.
- Control Group
Individuals without otosclerosis who have undergone temporal bone CT imaging for unrelated reasons. They have no history of conductive or mixed hearing loss. Their imaging and metabolic parameters will be compared with those of the otosclerosis patients to identify significant differences.
