The interest for telemedicine has increased since the COVID-19 pandemic because of the risk of infection. Recently, commercial companies started selling digital USB-otoscopes (DUO) that can be connected to a mobile phone. These DUOs are inexpensive (costing approximately $6–35 each) and make it possible to visualize the whole tympanic membrane. Here, we illustrate the case of a patient who had operative correction of a tympanic membrane retraction, and who self-monitored the tympanic membrane in the course of time. Additionally, we discuss the use of DUOs in otolaryngology telemedicine practice. The use of simple digital USB otoscopes provides a promising method to assess and monitor the tympanic membrane remotely. However, more research is needed to establish the role of DUOs in telemedicine.
