Study Details

Study Description

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.

Condition or Disease Intervention/Treatment Phase
  • Combination Product: Radiologic diagnosis
  • Diagnostic Test: Artificial intelligence diagnosis

Arms and Interventions

Arm 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

Combination Product: Radiologic diagnosis
Each CT scan is interpreted by a radiologist and is assigned as positive or negative for the diagnosis of otosclerosis

Diagnostic Test: Artificial intelligence diagnosis
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

Combination Product: Radiologic diagnosis
Each CT scan is interpreted by a radiologist and is assigned as positive or negative for the diagnosis of otosclerosis

Diagnostic Test: Artificial intelligence diagnosis
Each CT scan is screened by the deep learning algorithm and is assigned as positive or negative for the diagnosis of otosclerosis

Outcome Measures

Primary Outcome Measures

  1. 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 [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
