Hearing aid

Hearing aid devices can benefit older patients with trouble hearing and hereditary diseases that decrease their ability to hear sounds. Thousands of machines are used annually in developed countries. The tool is easy to use and might be applied to almost every patient with impaired hearing. In addition to standard variants, there are modern versions of hearing aids that are small enough to be invisible. Still, a profound medical examination is required to get the possible outcomes of hearing aid devices. At first, the patient gets an appointment with the otolaryngologist, who examines their previous medical records and asks for details about their current health status and symptoms. After a general physical examination, medical practitioners create a list of further diagnostic procedures that will help to pick up the most suitable hearing aid device. For example, during an endoscopic ENT examination, doctors look closely at some parts of the outer ears, and tympanometry helps them evaluate the middle ear's functions. During the measurement of the auditory canal, healthcare practitioners obtain indicators that will help them to ensure the device will fit tightly to the ear canal. Ultimately, medical practitioners summarize all info and propose the best type of hearing aid device. The only thing left is ensuring that the device suits the patient's ear well and successfully performs its functions.
