Background – Benign paroxysmal positional vertigo is a relatively
common benign disease of the inner ear, characterized by
severe attacks of vertigo triggered by certain head movements
or position changes. The condition is caused by tiny crystals that
stick in the semicircular canals of the ear and affect the balance
organ. Benign paroxysmal positional vertigo may occur in direct
relation to a head trauma, including removal of teeth and sinus
floor augmentation. The most common form of Benign paroxysmal
positional vertigo is often treated with The Epley manoeuver
in which the crystals are moved away from the posterior semicircular
canal. Patients generally experience a good effect of the
treatment and the prognosis is good, but recurrence may occur.
Case report – A 46-year-old woman was referred to the earnose-throat
surgeon for diagnosis and treatment of severe dizziness
and nausea. The day before, the patient had undergone
closed sinus lift with implant insertion in the left side of the upper
jaw. The medical history, clinical examination and Dix-Hallpike
position test verified the diagnosis of benign paroxysmal positional
vertigo. Treatment with The Epley manoeuver resulted
in symptom relief. No sign of relapse was observed after 2
months.
Conclusion – Benign paroxysmal positional vertigo may occur
immediately following dental treatment. The diagnosis is based
on the medical history, clinical examination and Dix-Hallpike position
test. The condition is usually well treated with The Epley
manoeuver, but recurrence may occur.
