An ENT otoscope, also known as an auriscope, is a medical instrument used by doctors to examine the ear canal and eardrum. It typically consists of a handle and a head containing a light source and a magnifying lens. Disposable specula, which are cone-shaped attachments, are used to gently insert into the ear canal to provide a clear view. Otoscopes are essential for diagnosing various ear conditions like infections, wax buildup, and eardrum perforations.
