Posterior Canalithiasis
Definition Posterior canalithiasis BPPV (Benign Paroxysmal Positional Vertigo) is caused by free-floating otoconia (tiny calcium carbonate crystals) that have dislodged from the utricle and entered the posterior semicircular canal. These loose crystals move with head position changes, creating abnormal fluid […]
Benign Paroxysmal Positional Vertigo (BPPV)
What is BPPV? BPPV is a mechanical disorder of the vestibular system characterized by repeated episodes of positional vertigo, caused by displaced otoconia (tiny calcium carbonate crystals) from the utricle that migrate into one of the semicircular canals (posterior, horizontal […]
Bow and Lean Test
Fundamentals The Bow and Lean or Head Pitch Test can be used help identify the affected ear in horizontal canal benign paroxysmal positional vertigo (HC-BPPV). It can be done as a second step after determining likely canalithiasis or cupulolithiasis type […]
Straight Head Hanging Test
Fundamentals The straight head hanging test or supine head hanging test (SHH) is a positional test used to assess for benign paroxysmal positional vertigo (BPPV), particularly involving the anterior canal and, in some cases, atypical variants of posterior canal BPPV. […]
Loaded Dix-Hallpike Test
Fundamentals The loaded Dix-Hallpike (L-DH) is a positional test used to improve diagnostic sensitivity for posterior canal BPPV, particularly in cases where the standard Dix-Hallpike test may seem normal, yet posterior canal BPPV is actually present. The test involves preloading […]
Side-lying Test
Fundamentals The side-lying test is a validated alternative to the Dix-Hallpike, assessing for ipsilateral posterior and contralateral anterior canal benign paroxysmal positional vertigo (BPPV). It is particularly beneficial for patients with physical or medical comorbidities such as pregnancy, low back […]
