|Description:||This image depicts a female clinician conducting an examination of a male patient’s right ear, using an otoscope, which she’d inserted into the right ear canal.|
Peering into the ear canal, the healthcare provider is able to see whether or not there are any pathogenic processes taking place in the canal itself, upon the ear drum, or tympanic membrane, and behind the ear drum, or inner ear.
An otoscope is a small, hand-held instrument with a light that is directed through a funnel-like tip to illuminate the ear canal for examination. The funnel-like tip is called a “speculum.” The specula are disposable and come in two sizes, 2.5mm for very small ear canals, and 4mm for average adult ear canals. The otoscope is powered by a rechargeable battery in the handle; the handle detaches and can be plugged into a standard wall outlet for recharging.
