Introduction: Nowadays, the use of images in medical practice is fundamental to examine hard places
to be reached. This can be obtained by endoscopy or microscopy, by connecting one
of these imaging instruments to a camera, and then transmitting images to a monitor.
With the images one can guide the student of medicine, patient, and resident in relation
to the anatomy, disease, and the procedures performed.
Methods: A 30-degree, 4-mm, 175-mm endoscope (Scholly) fixed on a video camera, connected
via USB video capture to an Internet-ready computer and enabled data transmission
via Skype to another computer in another room, connected to an image projector which
enlarged the images. Initially, the endoscope was handled by the teacher in a patient
identifying normal structures. Then one ear of a cadaver with a perforated eardrum
and the removal of a foreign body were shown. Two students observed the examination
on the monitor next to the teacher and four others in another room by means of the
multimedia projection image. All the students were asked to observe the examination
and listen to its description. After they identified the structures, they drew them
and answered a questionnaire.
Results: All the students were able to recognize the ear and oral structures, indicating their
positions in drawings (100%). Only one student in rhinoscopy failed to locate the
inferior nasal concha (83.33%).
Conclusion: The work enabled the transmission and amplification of images to assist the learning
of the ENT examination in an accessible and trivial way.
