๐ Differentiating between conductive and sensorineural hearing loss is essential in the clinical examination of hearing loss.
๐ Sensorineural hearing loss can be caused by inner-ear disease or damage to the cochlear nerve, resulting in impaired perception of sound waves via air and bone conduction.
๐ Conductive hearing loss is caused by diseases of the middle ear or obstructions in the outer auditory canal, leading to impaired air conduction but unaffected bone conduction.
๐ Impaired sound conduction makes the inner ear more sensitive towards bone conduction stimuli.
๐ The Rinne Test helps differentiate between sensorineural and conductive hearing loss.
โก๏ธ Conductive hearing loss impairs air conduction, while sensorineural hearing loss does not.
๐ The Weber and Rinne tests are used to assess hearing loss.
๐ A positive Rinne test indicates that air conduction is intact.
๐ The Weber test compares bone conduction in both ears to detect the origin of hearing loss.
๐ Unilateral sensorineural hearing loss causes sound to be louder on the unaffected side.
๐ Unilateral conductive hearing loss causes sound to be louder on the affected side.
๐ Differentiating between sensorineural and conductive hearing loss requires interpretation of results from both the Rinne and Weber Test.
โญ A bilaterally positive Rinne Test indicates conductive hearing loss.
๐ Weber test lateralized to the right suggests right-sided conductive hearing loss or left-sided sensorineural hearing loss.
โ A positive Rinne Test on both sides confirms normal air conduction.
๐ The Weber test can detect conductive or sensorineural hearing loss.
๐ A positive Rinne test indicates no significant conductive hearing loss.
๐๐ A negative Rinne test suggests conductive hearing loss.
๐๐ A normal Weber test points to symmetrical conductive hearing loss.
๐๐๐ Both the Rinne and Weber tests are useful for identifying different types of hearing loss.
๐ The Weber and Rinne tests are used to evaluate combined conductive and sensory neural hearing loss.
๐ The Weber test involves placing a vibrating tuning fork on the forehead to determine if hearing loss is unilateral or bilateral.
๐ The Rinne test compares air conduction and bone conduction to differentiate between conductive and sensory neural hearing loss.
