stapes motion test

Tibial activity test (GelletestGT): A test for the presence or absence of fixation in the tibia. When a lesion occurs, or the anvil joint is destroyed, it may cause a sound conduction disorder, and in severe cases, it may cause conductive deafness. The most common cause of damage to the tibia is otitis media, especially acute otitis media. If the treatment is not timely or incomplete, it will become chronic. Over time, it will cause perforation of the tympanic membrane, which will cause the ossicle to be affected, adhesion to the inner wall of the middle ear, fixation of the humerus, and loss of mobility of the anvil joint, resulting in severe hearing loss. Basic Information Specialist Category: Otolaryngology Examination Category: Other Inspections Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: Normal value: no Above normal: negative: When there is no change in the pressure and decompression sound, it is negative (GT "-"), which is a fixed sign of the humerus floor. Positive: Pressurization is a reduction in bone conduction sensation and recovery at decompression, which is positive for the tibia activity test (GT "+"), indicating normal tibia activity. Tips: The environment should be quiet when checking. Prevent hearing fatigue from affecting the results of the test. Normal value Pressurization is a reduction in bone conduction sensation and recovery at decompression, which is positive for the tibia activity test (GT "+"), indicating normal tibia activity. Clinical significance Abnormal results: When there is no change in pressure and decompression sound, it is negative (GT "-"), which is a fixed sign of the humerus floor. Need to check the crowd: deafness or hearing problems or a healthy checkup of the ear. Negative results may be diseases: deafness, neurological deafness considerations Taboo when checking: 1. The environment needs to be quiet. 2. Select the tuning fork of the appropriate frequency. 3. Tap the tuning fork according to a certain method. 4. The tuning fork is placed in the correct part during the test. 5. The fork of the tuning fork does not touch the fork, and the fork does not touch the hair. 6, the control ear must be normal, the age of the control should be equivalent. 7. Prevent hearing fatigue. Inspection process Place the vibrating C256 tuning fork sole in the sinus sinus area, and alternately pressurize and decompress the outer ear canal with the air otoscope. If the sound is strong or weak, that is, when the pressure is reduced, the bone conduction is reduced and the pressure is restored. That is, the tibia activity test is positive (GT "+"), indicating that the tibia activity is normal. If there is no change in the pressure and decompression sound, it is negative (GT "-"), which is a fixed sign of the humerus floor. Not suitable for the crowd Not suitable for inspectors: None. Adverse reactions and risks Nothing.
