Gradual hearing loss or blockage in one ear is very common That leads to a visit to the ENT office. However, a simple ringing fork test may be performed In the home to help diagnose whether a neurological problem is as opposed to something Milder like ear fluids or earwax. The 512Hz AC fork is the best tuner fork to use for these tests. There are two components of the tuning fork test. The Weber test shown here is performed Place a tuning fork vigorously in the middle of the forehead. Rinne's test It is done by placing a vibrating tuning fork first against the bone from behind The ear is followed by near the opening of the ear canal. When the setting fork is against the bone, One is examining bone conduction.
When the adjustment fork is placed close to the ear Duct, one conducts the exam air. The patient responds to each test by saying as they hear the sound at the loudest volume Both Weber and Rennes' binary test. The pattern of responses determines the type of hearing loss or cause of the ear blockage. How do these tests work? With the Weber test, if both ears are normal or if the patient has poor hearing Recall that the tuning fork is equally high in both ears. However, if there is an impaction or fluid in the earwax in the middle ear, the patient will report it The tuning fork is louder in the affected ear, in this case the right side. However, the same result can also be obtained if there is a nerve impairment of hearing, on the contrary Left ear.
In order to distinguish between these two possibilities, the Rinne test is performed For both sides. When Rinne is performed on the left side, the air conductivity is found to be higher than Bone conduction. Remember, whether or not nerve loss is present, always deliver air Higher than bone conduction unless connected. Hearing loss is present due to ear or earwax fluid. As such, when Rinne is performed on opposite the normal right ear, is again in tuning The sound of a thorn is louder than air conduction compared to bone conduction. As such, hearing loss in the left nerve is diagnosed due to a right-oriented, weber Air conduction was higher than bone conduction on both sides.
What happens if there is correct ear fluid and is there earwax? The patient will report that the tuning fork is louder in the right ear on Weber Test … but in Rinne, the patient will state that bone conduction is higher than air conduction On the right side, but not on the left side. At this point, you should be able to diagnose any hearing loss or ear blockage problem, Or at least narrow the possibilities.
First do the Weber test … followed by Rennes for both sides. Depending on the pattern of answers … Here's a chart to determine the cause of the hearing A complaint of loss and / or blockage of the ear..
