Interest of Using Deep Learning Algorithm for Otosclerosis Detection on Temporal Bone High Resolution CT (OtoIA)
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.

Cohorts and Interventions
Group / Cohort |
Intervention / Treatment |
---|---|
CASE
Patients 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
|
Each CT scan is interpreted by a radiologist and is assigned as positive or negative for the diagnosis of otosclerosis
Each CT scan is screened by the deep learning algorithm and is assigned as positive or negative for the diagnosis of otosclerosis
|
CONTROL
Random patients with a high resolution computed tomography scan of temporal bone performed without suspicion of otosclerosis and considered normal
|
Each CT scan is interpreted by a radiologist and is assigned as positive or negative for the diagnosis of otosclerosis
Each CT scan is screened by the deep learning algorithm and is assigned as positive or negative for the diagnosis of otosclerosis

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
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 curve
Time Frame: through 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
|
through study completion, an average of 5 months
