Interest of Using Deep Learning Algorithm for Otosclerosis Detection on Temporal Bone High Resolution CT

Active, not recruiting
Conditions
Otosclerosis
Interventions
Combination Product: Radiologic diagnosis
Diagnostic Test: Artificial intelligence diagnosis
Registration Number
NCT05987215
Lead Sponsor
Hospices Civils de Lyon
Brief Summary

Otosclerosis is a relatively frequent pathology, of multifactorial origin with genetic and hormonal part, predominantly in women. This disease causes a disorder of the bone metabolism of the middle and inner ear, responsible for a progressive deafness, which can become severe.

Several elements are necessary to make the diagnosis of otosclerosis: the clinical examination and questioning, the audiometric assessment, and finally the temporal bone CT.

The CT scan allows to detect foci of otosclerosis within the bone of the middle or inner ear. This diagnosis is sometimes difficult and requires interpretation by a trained radiologist.

The investigators would like to evaluate the ability of a deep learning algorithm to detect these foci of otosclerosis, and to compare its diagnostic performance with a trained radiologist.

CASERadiologic diagnosisPatients with surgically confirmed otosclerosis who initially consulted for conductive hearing loss with normal otoscopy, and with a high resolution computed tomography of temporal bone available
CASEArtificial intelligence diagnosisPatients with surgically confirmed otosclerosis who initially consulted for conductive hearing loss with normal otoscopy, and with a high resolution computed tomography of temporal bone available
CONTROLArtificial intelligence diagnosisRandom patients with a high resolution computed tomography scan of temporal bone performed without suspicion of otosclerosis and considered normal
CONTROLRadiologic diagnosisRandom patients with a high resolution computed tomography scan of temporal bone performed without suspicion of otosclerosis and considered normal
Primary Outcome Measures
NameTimeMethod
Diagnostic performance of the artificial intelligence algorithm compared to the diagnostic performance of the radiologist : sensitivity, specificity, positive and negative predictive value, area under the ROC curvethrough study completion, an average of 5 months

These diagnostic performances will be established from the positive or negative diagnoses of the algorithm and the radiologist, compared to the "case" or "control" status of each patient included in the study
