Tympanometry

After performing otoscopy, Dr. Light moves onto the next step in all of her evaluations which is tympanometry.Tympanometry is a non-behavioral test of middle ear function, which means it requires no voluntary response on the part of the client being tested. Tympanometry is completed with the use of a probe inserted into the ear canal. This test helps determine ear canal volume,the mobility of the tympanic membrane (eardrum), and if there is a presence of fluid in the middle ear. Middle ear fluid can collect behind oureardrums without ever being noticed by other professionals during quick, routine examinations.The fluid in a child’s middle ear can cause up to a 50-60% hearing loss, especially if it has been present for a long time and thickens.This not only makes it difficult for the child to hear and produce speech but will also affect their vestibular (balance) system. Fluidand negative pressure found in the middle ear causes sensory deprivation andcan translate to gross motor delays or the skipping of important milestones.To see how otoscopy and tympanometry is performed at Brainchild Institute please watch our two-part YouTube video series linked below.
