Clinical Trial Summary

For diagnosis of external and middle ear diseases, an otoscope is a key instrument to use. A microscope has been used as a reference standard to confirm pathology. An endoscope has been also widely used. Both microscope and endoscope provide an excellent image quality, can record and capture the images, and the images can be visualized with an export system.

A digital otoscope is widely available and more affordable. A comparative study of the efficacy of the endoscope and the digital endoscope will be performed.

Description:

A comparative study for the diagnosis of middle ear disease usingTeslong digital otoscope, model MS450D39, and the otoendoscope will be performed. The participants will be recruited at the ENT clinic, University Hospital. A handheld otoscope will be used to identify the patients who have the pathology of the middle ear.

The images will be captured with both endoscopes and will be reviewed by staff, residents training in ENT, and residents training in ENT and family medicine.
