Benign paroxysmal positional vertigo (BPPV) is a rare complication of Le Fort I osteotomy of labyrinthine origin, usually
characterized by brief recurrent episodes of vertigo. Head trauma accounts for the large percent of (BPPV). Surgical mallet
and osteotomes used in pterygoid osteotomy induce trauma, which can displace otoliths into the semicircular canal leading to
incapacitant symptoms. Diagnoses can be confirmed through history and physical examination, including positive Dix–Hallpike
test. In This article a Benign paroxysmal positional vertigo case is presented. Management of the case through collaborative
assessment process, planning, care coordination, and proper treatment was provided. Awareness of a rare complication such as
BPPV is of utmost importance when patients complain of dizziness following orthognathic surgery.
