The Weber test is administered by holding a vibrating tuning fork on top of the patient's head. The Weber test is a screening test for hearing performed with a tuning fork. [1] [2] It can detect unilateral (one-sided) conductive hearing loss (middle ear hearing loss) and unilateral sensorineural hearing loss (inner ear hearing loss). [3]
This test is usually abnormal with conductive hearing loss. A type B tympanogram reveals a flat response, due to fluid in the middle ear (otitis media), or an eardrum perforation. [ 5 ] A type C tympanogram indicates negative middle ear pressure, which is commonly seen in eustachian tube dysfunction. [ 5 ]
Weber test, in which a tuning fork is touched to the midline of the forehead, localizes to the normal ear in people with unilateral sensorineural hearing loss. Rinne test, which tests air conduction vs. bone conduction is positive, because both bone and air conduction are reduced equally. less common Bing and Schwabach variants of the Rinne test.
Thus, a "positive" result indicates the healthy state, in contrast to many other medical tests. Therefore, some prefer to avoid using the terms "positive" or "negative", and simply state if the test was normal or abnormal. For example: "Rinne's test was abnormal in the right ear, with bone conduction greater than air conduction".
The prevalence of impacted earwax is different across the world. In the United Kingdom 2 to 6% of the population have cerumen that is impacted. In America 3.6% of emergency visits caused by ear issues were due to impacted cerumen. In Brazil 8.4–13.7% of the population have impacted cerumen. [46]

The auditory brainstem response test (ABR) is a cost-effective test to see if a VS has perhaps compromised the cochlear nerve. [citation needed] Computed tomography (CT scan) of the head will detect moderate to large sized VS but can miss small sized VS. VS appears as isodense to surrounding brain parenchyma on CT. VS does not have ...
