Rinne’s test compares the air conduction (AC) and bone conduction(BC) in the same ear. The interpretations are:
(a) Rinne positive- when AC is better than BC found in Normal hearing and SNHL
(b) Rinne Negative- when BC is better than AC found in Conductive and Mixed hearing loss.
(c) Rinne reduced positive- where AC is better than BC but with reduced BC seen in SNHL
(d) Rinne equivocal- when AC and BC are equal seen in mild conductive deafness.
(e) Rinne false negative-where BC is heard apparently longer in a case severe unilateral SNHL as the sound is transmitted through the skull to the other ear.
(f) Rinne infinitely positive where the patient hears momentarily a vibrating tuning fork by AC but does not hear by BC. This is seen in profound SNHL of the test ear.
(g) Rinne infinitely negative – profound conductive deafness
