This study aims to determine the amplitude changes in the test–retest condition of distortion product otoacoustic emissions (DPOAEs) and transient-evoked otoacoustic emissions (TEOAEs), which are widely used in clinical settings. Design DPOAE and TEOAE measurements were taken in 110 ears of 55 adults aged 18–35 years with normal hearing during three sessions. The repeatability of the measurements was evaluated by very short-term measurements taken 20 min after the first measurement and by short-term measurements taken 20 days after the first measurement. Results There was no statistically significant difference between the three measurements in which DPOAE and TEOAE amplitudes were evaluated. The weakest reliability for TEOAEs was determined at frequencies of 1.0 kHz and 1.5 kHz, and the weakest reliability for DPOAEs was determined at 6728 Hz. Conclusions The ...

The majority of patients with positioning vertigo with BPPV that affects either the posterior (PC-BPPV) or the horizontal (HSC-BPPV).There is evidence that anterior canal BPPV (AC-BPPV) is the least common type of BPPV. The cupulolithiasis and canalithiasis pathophysiologic mechanisms continue to be the two primary theories explaining BPPV. There are several maneuvers that have been designed to evaluate each semicircular canals. Although the prevalence, pathophysiology, clinical presentation and diagnostic criteria are well known, yet the condition often goes undiagnosed or is treated inappropriately. In this review, we have provided the classification, prevalence, pathophysiologic mechanisms, evaluation techniques and diagnostic criteria of BPPV.
