Anterior Canalithiasis
Definition Anterior or superior 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 anterior semicircular canal. These loose crystals move with head position changes, creating […]
Horizontal Cupulolithiasis
Definition Horizontal or lateral cupulolithiasis BPPV (Benign Paroxysmal Positional Vertigo) typically occurs when otoconia (tiny calcium carbonate crystals) adhere to the cupula of the horizontal semicircular canal, rendering it abnormally sensitive to gravity. This results in a persistent, apogeotropic horizontal nystagmus […]
Horizontal Canalithiasis
Definition Horizontal or lateral canalithiasis BPPV (Benign Paroxysmal Positional Vertigo) occurs when free-floating otoconia (tiny calcium carbonate crystals) have dislodged from the utricle and entered the horizontal semicircular canal. With head movements, gravity and inertia cause these particles to shift, generating […]
Posterior Cupulolithiasis
Definition Posterior cupulolithiasis BPPV (Benign Paroxysmal Positional Vertigo) is a less common variant of BPPV resulting from otoconia dislodged from the utricle that become adhered to the cupula of the posterior semicircular canal. This increases the cupula’s specific gravity, causing […]
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 […]
