An otoscope potentially gives a view of the ear canal and tympanic membrane or eardrum. It is imperative that visualization of an intact tympanic membrane (eardrum) is noted. It gathers sound energy and focuses it on the eardrum (tympanic membrane). The inner surface of the tympanic membrane is innervated by the glossopharyngeal nerve. The malleus is attached to the tympanic membrane and articulates with the incus. Calcium phosphate plaques then form in the lamina propria of the tympanic membrane. General avian tympanic membrane form is ovular and slightly conical. The risk of persistent tympanic membrane perforation after children have grommets inserted may be low. The two canals are called the vestibular canal and the tympanic canal. The posterior and superior parts of the tympanic membrane are most commonly affected. Hz probe tone was used to monitor the vibrations of the tympanic membrane. Functional keratinocytes are needed for tympanic perforation healing. The auricle, ear canal, and tympanic membrane are often referred to as the external ear. Patients suffering from tympanic membrane rupture may experience bleeding, tinnitus, hearing loss, or disequilibrium (vertigo). This also allows some inspection of the middle ear through the translucent tympanic membrane.
