Infection symptom of perforation of eardrum?

summary

The tympanic membrane, also known as the eardrum, is an oval translucent membrane, which is composed of epithelial layer, fibrous layer and mucous layer. It is located at the junction of the middle ear tympanic chamber and the external auditory canal, and forms the lateral wall of the story. In particular, it divides the external auditory canal and the middle ear cavity, and blocks the obligation to protect the external auditory canal. Bacteria and other bacteria enter the middle ear cavity, The structure of tympanic membrane can make the incoming sound wave gain and compensate the attenuation of the incoming sound wave. The causes of perforation of eardrum are mostly caused by inflammation or trauma. Because of the anatomical characteristics of children, the eustachian tube connecting the nasal cavity and the middle ear cavity occurs frequently. When the upper respiratory tract infection occurs, the bacterial secretions in the nasal cavity can easily reach the middle ear cavity through the eustachian tube, causing infection. At the same time, if the breast-feeding posture is not correct, milk also easily through the eustachian tube into or choked into the middle ear, the occurrence of acute otitis media, leading to tympanic membrane perforation. Infection symptom of perforation of eardrum? Let's talk about it.

Infection symptom of perforation of eardrum?

Acute tympanic membrane perforation caused by otitis media, patients rarely have ear pain, tympanic membrane perforation pain can be reduced, and there may be liquid outflow. Traumatic tympanic membrane perforation, tympanic membrane rupture, patients with sudden pain, hearing loss immediately, accompanied by tinnitus, a small amount of external auditory canal bleeding and ear stuffy feeling.

Acute otitis media caused by tympanic membrane perforation, tympanic membrane diffuse congestion and swelling, normal signs are difficult to identify, pus outflow or fluctuating bright spots (Lighthouse sign) can be seen at the window, hearing tests are mostly conductive deafness, most can be mixed and nerve deafness.

Traumatic tympanic membrane perforation, the tympanic membrane is irregular or fissure shaped perforation, accompanied by rain, snow, blood and cigars, such as blood loss or with water outflow, to consider the possibility of cerebrospinal fluid otorrhea, hearing prosecutor's office conductive or mixed deafness. This requires the removal of foreign bodies and clots in the external auditory canal.

matters needing attention

Systemic treatment should be early application of sufficient antibiotics to control infection, penicillin, cephalosporin and other drugs can be selected, local treatment, first with 3% hydrogen peroxide cleaning, external auditory canal after the use of antibiotics, a little liquid point to use, inflammation control can not heal after the perforation, can consider surgical repair.
