Benign Paroxysmal Positional Vertigo Following Sinus Floor Elevation in Patient with Antecedents of Vertigo

Abstract

Benign paroxysmal positional vertigo (BPPV) is an unfamiliar and rare complication occurring following osteotome sinus floor elevation (OSFE) and simultaneous implant placement. Etiology of this disorder is commonly displacement of otoliths by vibratory forces transmitted by osteotomes and mallet along with the hyperextension of the head during the operation, causing them to float around in the endolymph. This report presents a case of protracted BPPV following OSFE and simultaneous implant placement. A 43-year-old female suffered intense vertigo and nausea immediately after implant placement using an OSFE procedure. Upon further questioning after the procedure she gave an account of two times vertigo history within the last 9 years. Despite nootropic drug medication and canalith repositioning procedure applied by a specialist at operation night, the condition did not improve. Patient did not totally recover and was admitted again after 1 month. After repeated maneuvers, nine dosage intravenous serous fluid and piracetam administration the patient recovered. Duration of these procedures took 10 days and the patient was successfully treated with no recurrence of dizziness. Prevention and management of OSFE related BPPV are reviewed especially in patients having prior vertigo history in this report.
