Deep learning for automated diagnosis and differentiation of otitis media on temporal bone CT.
Article in BMC medical imaging, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe accurate diagnosis of otitis media (OM) has long been a challenge for clinicians (especially for less experienced clinicians) due to the variety of types and the complex anatomical structures of the middle ear. Although deep learning (DL) based on different examination methods (mostly otoscopy) has been applied to the diagnosis of single species OM in previous studies, DL using temporal bone computed tomography (TBCT) images to diagnose OM and simultaneously differentiate between chronic otitis media (COM) and otitis media with effusion (OME) has not been investigated in depth. This study aimed to develop and evaluate a DL framework for the automated diagnosis of OM and identifying OME and COM with or without cholesteatoma using TBCT images.
methodsOur team created a unique large dataset of 2011 TBCT images from 1200 patients who were diagnosed with OM, which was determined the regions of interest (ROI) for middle ear (ME) by experienced experts. Then, a DL model was trained to detect the MEs in TBCT images and determine the OM status with this dataset of pre-processed images. Five-fold cross-validation was utilized for training and selecting the models. Finally, we evaluated the model using 406 images and verified the effectiveness of model-assisted diagnosis for different levels of clinicians in a comparative study.
resultsIn the detection of the ME, the DL model achieved a detection ratio of 98.53%. The model showed satisfying performance in the classification of normal middle ear (NME), OME, and COM with an accuracy of 0.9238. With the assistance of the DL, the diagnostic accuracies were significantly improved from 81.53% to 93.60% (junior clinician) and from 87.93% to 95.57% (senior clinician), respectively.
conclusionsThe findings suggested that the DL model could accurately identify MEs in TBCT images and classify NME, OME, and COM with satisfying accuracy. DL could also effectively assist clinicians in TBCT interpretation for OM diagnosis.
