Eustachian tube obstruction
Introduction
Introduction to Eustachian Tube Blocking The cartilage segment of the eustachian tube is anatomically normal, but its function is impaired, that is, the eustachian tube is passively open and cannot be opened. It is different from the pharyngeal obstruction caused by general inflammatory edema. In the past, the treatment of the disease used the middle ear negative pressure to treat the rule of law, such as puncture, insertion and drainage, only to obtain a short-term effect, can not achieve long-term cure. In 1976, Misurya first used the sacral muscle tendon shortening technique, that is, the patient took the father and son to lie down, and after the third molar, the inner wing hook was used for submucosal local infiltration anesthesia with 1% lidocaine. A 2 cm curved incision was made on the outside to expose the wing hooks, and the sacral tendon was peeled off from the wing hooks to the inner and outer sides of the deep layer, and the 3° nylon thread was passed on both sides of the wing hook through the sacral tendon, wrapping the wing hooks. Shorten the ligation, generally shortened by 0.5 cm, and the symptoms can be relieved. basic knowledge The proportion of sickness: 0.01% Susceptible people: no specific population Mode of infection: non-infectious Complications: deafness
Cause
Eustachian tube obstruction
1. Glasscock and House believe that the eustachian tube cartilage is softened, and the cause of cartilage softening of the eustachian tube is unknown.
2. The muscles of the sacral muscles are weak or the pharyngeal nerves are paralyzed, so that the throat can not be opened actively.
Prevention
Eustachian tube obstruction prevention
No effective precautions.
Complication
Eustachian tube obstruction complications Complications
Conductive deafness can occur.
Symptom
Eustachian tube obstruction symptoms common symptoms proliferative gland hypertrophy hearing loss tympanic congestion
According to the history and physical signs, the normal examination is performed by Valsalva ventilation method. For this reason, it is best to perform the acoustic impedance test. The tympanic pressure is unchanged when swallowing and yawning in this case. When the nose is blown vigorously, gas enters the tympanic cavity.
Examine
Eustachian tube obstruction
Otoscope examination of the tympanic membrane is turbid, invagination, and sometimes tympanic effusion, it is best to conduct acoustic impedance test.
Diagnosis
Eustachian tube obstruction diagnosis
The disease is similar to secretory otitis media, need to be identified, the disease is easily misdiagnosed as eustachian tube inflammatory obstruction and tympanic incision or intubation, otoscope examination of tympanic membrane turbidity, invagination, and sometimes tympanic effusion.
