Tele-otology: planning, design, development and implementation.

Abstract

The view of the tympanic membrane of the ear provides the specialist with important information for the assessment of ear disease and for treatment planning. In rural and remote areas, the incidence of ear disease is high but access to ear specialists is limited. As part of a project to deliver tele-otoscopy services to remote Western Australia, we have investigated various aspects of a tele-otoscopy system. We found that the MedRX video-otoscope is relatively safe to use and produces images of very good quality. A confident diagnosis could be made from still images compressed to 20 kByte. Video sequences could be compressed to a ratio of 1:300. Furthermore, a software package has been developed, and we are developing a training course for health-care workers in remote areas.
