tympanic membrane disorders


ENT Clinic Hospital of Nanjing Military Area Command Center in authority, often to see the different types of tympanic membrane perforation patients. Some cases of influenza caused by perforation of acute otitis media, or ear accidentally dug through digging; some nursing infants and young children because of improper discharging ear caused by vomit after milk; even when playing with a ball and hit the ear or hand, was scraping slap fight, firecrackers explode may also cause tympanic membrane perforation; occasionally visible tympanic membrane perforation caused by insect ear.
Traumatic tympanic membrane rupture characteristics:
(1) identification of traumatic tympanic membrane rupture, men more common than left ear right ear, mostly because of injury slap.
(2) tympanic membrane perforation in this group occurred in a tense Department, previously the highest incidence of lower quadrant, about 55%, and continue to report similar.
(3) The poor blood supply to the tympanic membrane, tympanic membrane in this group after the congestion of blood around the fracture callus or a small amount of bleeding.
Tympanic membrane perforation Care
1, with tympanic membrane perforation, need special attention: Keep the ears dry and clean; prohibit swimming and pay attention to water-soaked invasion.
2, in the repair of the to NOTE: Keep ear canal dry and clean; not to do strenuous exercise and heavy labor; attention to prevention of colds, nasal breathing to maintain patency; not chew hard foods; others see above the external auditory canal, tympanic membrane disease care.
ENT Clinic Hospital of Nanjing Military Region, central authority experts have warned that, as time goes on, the case of traumatic tympanic membrane rupture may occur to some extent the changes, in particular, secondary infection, traumatic perforation of tympanic membrane to lose the unique shape, small broken can be healed in a short time, it is our assessment of the injury more difficult. In view of this, we often in traumatic tympanic membrane rupture, early video, to record the initial rupture of the tympanic membrane after injury, the performance appraisal for the future to provide a more objective basis.
tympanic membrane disorders

REVIEW: tympanic membrane damage: 1, by the protective effect of middle ear damage, the side of the middle ear the tympanic membrane is the gateway to the outer ear and middle ear by its separated, to protect the middle ear cavity. After piercing the outside of bacteria, sewage, foreign body perforation of the middle ear can cause infection by pus.
Tympanic membrane damage
1, the protective effect of the middle ear has been damaged, one side of the middle ear the tympanic membrane is the gateway to the outer ear and middle ear by its separate, protecting the middle ear cavity. After piercing the outside of bacteria, sewage, f
oreign body perforation of the middle ear can cause infection by pus.
2, perforated so that hearing loss: sound vibration of the tympanic membrane first, and then spread through the cochlea in the ears ossicular chain, thereby causing the formation of hearing nerve reflex, tympanic membrane perforation, tympanic membrane reducing the effective vibration area, outside the energy of incoming sound waves weaken the inner ear, there hearing loss.
Tympanic membrane - Disease Care:
1, with tympanic membrane perforation, need special attention: Keep the ears dry and clean; prohibit swimming and pay attention to water-soaked invasion.
2, in the repair of the to NOTE: Keep ear canal dry and clean; not to do strenuous exercise and heavy labor; attention to prevention of colds, nasal breathing to maintain patency; not chew hard foods; others see above the external auditory canal, tympanic membrane disease care.
If repaired tympanic membrane, is the best but it not only can improve hearing, but also to re-establish a barrier to prevent recurrent otitis media and to avoid causing long-term use ear drops ototoxic damage.
Also called the eardrum tympanic membrane (Eardrum), commonly known as ear mirrors, a population of about 2.5 cm away from the external auditory canal -3 cm, between the location of the external auditory canal and tympanic. Tympanic membrane height of about 9 mm, a width of 8 mm, the average size of about 90 square millimeters, the thickness of 0.1 mm, not much thicker than paper, is a flexible film.
Although the tympanic membrane is thin, but its solution structure of the Department has 3 layers, outer layer of the skin, the inner mucous membrane, including the Ministry of the radial and circular fibers of the composition. Therefore, the tympanic membrane have a certain flexibility and tension. A small portion of the tympanic membrane is not above the middle fibrous layer, more Pu and loose, as the Ministry of relaxation; and fibrous part of the tympanic membrane, called the tension department.
Tympanic membrane appearance of pale, have a certain gloss, as the ground glass-like, translucent, outgoing malleus handle attached to the tympanic membrane embedded in the top down, the ends of central tympanic membrane, and thus the traction of the tympanic membrane, so that funnel-shaped, it is Like the radio speakers. The most central depression called the tympanic membrane umbilicus.
The role of t
he tympanic membrane with a set of sound and public address. The acoustic impact of the tympanic membrane, tympanic membrane vibration in the central part around together, the increasing power of the vibration, the malleus handle transmission, causing tympanic ossicular chain and the air vibrate, and then the oval window by the inner ear (vestibular window) exciting changes inside and outside the lymph the liquid wave, vibration basement membrane, so that the spiral is located on the basement membrane are stimulated, the auditory nerve impulse conduction and then listen to the brain center, which produces hearing.
Tympanic membrane to protect the inner ear the round window membrane, so that too much interference from acoustic injury. Tympanic membrane can protect the middle ear, and if ruptured eardrum perforation, the bacteria invade the middle ear cavity easy to directly otitis media occurs.
