Patients with vertiginous symptoms will ultimately be diagnosed with BPPV in 17% to 42% of cases, making BPPV the most frequent cause of vertigo. In the case of BPPV, aberrant signals from semicircular canals create an illusion of motion which results in vertigo. Vertigo is defined as the subjective perception of rotational or translational movement in the absence of an external stimulus. Symptoms are provoked by positional changes of the head with respect to gravity and can range in severity from mild dizziness to debilitating episodes that may induce nausea or vomiting, and significantly hinder daily functioning. Level of Evidenceīenign paroxysmal positional vertigo (BPPV) is the most common peripheral vestibular end-organ disease and is typified by a sudden, transient gyratory sensation which is accompanied by characteristic nystagmus. For a small subset of patients with intractable BPPV, canal occlusion can be considered. BPPV is generally amenable to in-office repositioning techniques. ConclusionsĪ diagnosis of BPPV can be made through clinical history along with diagnostic maneuvers.
Options for operative intervention are available for intractable cases or patients with severe and frequent recurrences. Of these, the particle repositioning maneuver is an effective way to treat posterior canal BPPV, the most common variant. Understanding the pathophysiology of both canalithiasis and cupulolithiasis has allowed for the development of various repositioning techniques. The diagnosis can be established with a Dix-Hallpike maneuver for the posterior and anterior canals, or supine roll test for the horizontal canal, and typically does not require additional ancillary testing. While often self-limited, BPPV can have a considerable impact on quality of life. ResultsīPPV is typified by sudden, brief episodes of vertigo precipitated by specific head movements. MethodsĪ comprehensive review of the literature regarding BPPV up through June 2018 was performed. The pathophysiology, diagnosis, nonsurgical, and surgical management are discussed. This article aims to summarize research findings and key discoveries of BPPV. The doctor holds you in this position for 30 seconds.Benign paroxysmal positional vertigo (BPPV) is the most common peripheral vestibular end-organ disease. When your head is on the table, you are now looking down at the table. The doctor then quickly moves you to the other side of the table, without stopping in the upright position.The doctor holds you in this position for 30 seconds. When your head is on the table, you are looking up at the ceiling. The doctor then lowers you quickly to the side that causes the worst vertigo.The doctor turns your head so that it is halfway between looking straight ahead and looking away from the side that causes the worst vertigo.First, you sit on the examination table with your legs hanging off the edge.When your head is firmly moved into different positions, the crystal debris (canaliths) causing vertigo moves freely and no longer causes symptoms. A single 10- to 15-minute session usually is all that is needed. The Semont manoeuvre is done with the help of a doctor or physiotherapist. The doctor will then help you to sit back up with your legs hanging off the table on the same side that you were facing.
