The vestibular part of the membranous labyrinth consists of three semicircular canals as anterior, posterior, and horizontal, and two otoliths as utricle and saccule; the source of the calcium carbonate crystals (otoconia) that are responsible for BPPV is the macula of the saccule (4).
Thereafter, hashed abdominal fat combined with human fibrin sealant is injected into the middle ear cavity, remaining dissected utricle, saccule, and cells of the petrosal apex around the IAC.
In BPPV, degenerative debris dislocated from the utricle into the semicircular canals increase the density of the cupula (1).
Benign paroxysmal positional vertigo is caused by otoconial debris which gets dislodged from the utricle and by way of gravity, precipitates to the semicircular canals7.
Calcium debris from the utricle enter the dependant part of the semicircular canals--which is posterior canal in most cases.

Pathologic studies have demonstrated that neuronal degeneration in maculae and cristae with neuroepithelium damage in the utricle, saccule, and ampulla of the semicircular canals are responsible for this condition.

Benign positional vertigo (BPV) is a common and correctable cause of episodic vertigo triggered by otoconia dislodged from the otolith membranes of the utricle into the semicircular canals.
It occurs when otoconia that are normally embedded in gel in the utricle become dislodged and migrate into the 3 fluid-filled semicircular canals, where they interfere with the normal fluid movement these canals use to sense head motion, causing the inner ear to send false signals to the brain.
