Objective: Otoscopy is a frequently performed procedure and competency in this skill is important across many specialties. We aim to systematically review current medical educational evidence for training of handheld otoscopy skills.
Methods: Following the PRISMA guideline, studies reporting on training and/or assessment of handheld otoscopy were identified searching the following databases: PubMed, Embase, OVID, the Cochrane Library, PloS Medicine, Directory of Open Access Journal (DOAJ), and Web of Science. Two reviewers extracted data on study design, training intervention, educational outcomes, and results. Quality of educational evidence was assessed along with classification according to Kirkpatrick's model of educational outcomes.
Results: The searches yielded a total of 6064 studies with a final inclusion of 33 studies for the qualitative synthesis. Handheld otoscopy training could be divided into workshops, physical simulators, web-based training/e-learning, and smartphone-enabled otoscopy. Workshops were the most commonly described educational intervention and typically consisted of lectures, hands-on demonstrations, and training on peers. Almost all studies reported a favorable effect on either learner attitude, knowledge, or skills. The educational quality of the studies was reasonable but the educational outcomes were mostly evaluated on the lower Kirkpatrick levels with only a single study determining the effects of training on actual change in the learner behavior.
Conclusion: Overall, it seems that any systematic approach to training of handheld otoscopy is beneficial in training regardless of learner level, but the heterogeneity of the studies makes comparisons between studies difficult and the relative effect sizes of the interventions could not be determined.

Objective: Otoscopy is a key clinical examination used by multiple healthcare providers but training and testing of otoscopy skills remain largely uninvestigated. Simulator-based assessment of otoscopy skills exists, but evidence on its validity is scarce. In this study, we explored automated assessment and performance metrics of an otoscopy simulator through collection of validity evidence according to Messick's framework.

Purpose: To investigate the utility of a hand-held digital otoscope for nasal endoscopy and as a pedagogy tool for residents and fellows in patients undergoing external dacryocystorhinostomy (DCR) surgery.
Methods: A digital otoscope (MS450-NTE, Teslong Inc., USA) comprising a digital screen device and a connectible camera probe was used for performing nasal endoscopy.

Prior work has demonstrated improved accuracy in otitis media diagnosis based on otoscopy using artificial intelligence (AI)-based approaches compared to clinician evaluation. However, this difference in accuracy has not been shown in a setting resembling the point-of-care. In this study, we compare the diagnostic accuracy of a machine-learning model to that of pediatricians using standard handheld otoscopes.

Otitis media (OM), a common ear infection, is characterized by the presence of an accumulated middle ear effusion (MEE) in a normally air-filled middle ear cavity. While assessing the MEE plays a critical role in the overall management of OM, identifying and examining the MEE is challenging with the current diagnostic tools since the MEE is located behind the semi-opaque eardrum. The objective of this cross-sectional, observational study is to non-invasively visualize and characterize MEEs and bacterial biofilms in the middle ear.

Handheld otoscopy is the standard tool used to teach ear examination in undergraduate and postgraduate medical education. Previous studies have shown that the undergraduate teaching of ear examination with handheld otoscopes is inadequate, resulting in low self-reported levels of student confidence in their diagnostic skills. With the increase in popularity of endoscopic ear surgery, an increasing number of otolaryngologists are using endoscopes for office examinations of the ear due to the method's superior visualization and excellent image qualities.
