Sentiero Desktop puts every middle ear test at your fingertips!

Middle ear testing is used to determine the overall health and function of the middle ear. These tests are essential in identifying perforations of the eardrum, abnormal pressure in the middle ear space, wax blockage in the ear canal, and possible conductive hearing loss.
