Eustachian tube examination

The examination of the eustachian tube (examination of eustachian tube) is to blow air into the middle ear through the eustachian tube to check the patency of the eustachian tube, the presence or absence of stenosis and obstruction, the presence or absence of liquid retention outside the drum, and the treatment. Basic Information Specialist classification: growth and development check classification: other inspection Applicable gender: whether men and women apply fasting: not fasting Tips: Not suitable for people: acute inflammation in the nasal cavity and nasopharynx, purulent secretion in the nose and nasopharynx. Normal value The Eustachian tube is unobstructed. Clinical significance Abnormal results Eustachian tube obstruction. Need to check patients with eustachian tube dysfunctional otitis media. Precautions Taboo before inspection: None. Contraindications during examination: Ensure that there is no acute inflammation in the nasal cavity and nasopharynx. If there is obstruction or secretion in the nasal cavity, 1% ephedrine solution should be added first to make the nasal mucosa contract, and the secretions can be removed before examination. The intensity of the inspection process should be moderate and not too violent. Inspection process There are three main methods: 1. Pinch the nose and suffocate the method. After the patient inhales, use your fingers to pinch the nostrils on both sides, close the mouth, and forcefully exhale from the nose to make the pharyngeal air rush into the Eustachian tube. 2. The balloon blowing method means that the patient's mouth contains water. The olive head of the eustachian tube is inserted into the pupil of one side of the patient, and the other side of the nose is pressed with the finger. When the water is swallowed, the sphere is pressed and the air is pressed. Can be flushed into the eustachian tube. 3. Catheter blowing method, that is, the patient takes a seat, after cleaning the nasal secretions, the elbow tube catheter elbow is inserted slowly down the bottom of the nose, reaching the posterior wall of the nasopharynx, then turning to the outside 90°, then slightly pulling forward , the catheter is slid over the bulge and into the mouth of the eustachian tube. Fix the catheter, inject air through the catheter with a blown ball, and listen to the ear with auscultation to check whether the Eustachian tube is patency or not. Not suitable for the crowd Not suitable for people: acute inflammation in the nasal cavity and nasopharynx, purulent secretion in the nose and nasopharynx.
