Schwabach test

The Schwabach test compares the length of time between the test subject and the normal ear bone. Both ears were tested separately. The length of the bone conduction hearing time is alternately tested by alternately placing the sole of the slamming fork on the mastoid portion of the affected ear and the contrasting ear (normal ear). Basic Information Specialist Category: Otolaryngology Examination Category: Other Inspections Applicable gender: whether men and women apply fasting: not fasting Tips: Before taboo: need to clean your ears. Normal value If the two are equal, recorded as ST "±", the ear bones of the examined ear are normal. Clinical significance Abnormal results: 1 If the ear bone conduction time is longer than the normal ear, and the bone conduction comparison test is extended as ST "+", the affected ear is conductive deafness. 2 If the ear bone conduction time is short, the bone conduction contrast test is shortened, and the ST "-" is recorded, and the affected ear is a sensorineural hearing loss. Need to check the patient's conductivity or sensory deafness patients. Precautions Contraindications before inspection: You need to clean your ears. Taboo when checking: 1 The environment needs to be quiet. 2 Select the tuning fork of the appropriate frequency. 3 Tap the tuning fork in a certain way. 4 The tuning fork is placed in the correct position during the test. 5 The fork of the tuning fork does not touch the fork, and the fork does not touch the hair. 6 Control ears must be normal, and the age of the controls should be comparable. 7 to prevent hearing fatigue. Inspection process Both ears were tested separately. The length of the bone conduction hearing time is alternately tested by alternately placing the sole of the slamming fork on the mastoid portion of the affected ear and the contrasting ear (normal ear). Not suitable for the crowd Not suitable for inspectors: None.
