An otoscope is a medical instrument used by healthcare professionals to examine the ear canal and eardrum. It consists of a light source and a magnifying lens, allowing for a clear view of the ear's internal structures. This tool helps in diagnosing conditions such as ear infections, blockages, or injuries. The otoscope typically has a disposable speculum that fits into the ear, ensuring hygiene during examinations. It is commonly used by doctors, nurses, and audiologists in various healthcare settings. Regular use of an otoscope can aid in early detection of ear-related issues, promoting better ear health.
