High-definition otoscopic device for humanitarian mission: how i do it

Background: Despite a high prevalence of chronic otitis media and related complications, many African dispensaries and clinics lack microscopes or fiberoptic equipment for examining external ear ducts and tympanic membranes. Method: An alternative, inexpensive, and readily available device designed for ear wax removal is presented as a clinical ear and anterior nasal cavity examination tool. The device connects to Wi-Fi or cellular networks, providing high-definition images of the ear and anterior nasal cavity through a smartphone interface. Its use, utility, strengths, and limitations are discussed. Conclusion: This paper describes a novel, cost-effective, and user-friendly device for examining the external ear, tympanic membrane, and anterior nasal cavity of patients throughout humanitarian missions.
