Benign Paroxysmal Positional Vertigo (BPPV) — Epley Manoeuvre Specialist in Hyderabad at KIMS
Benign Paroxysmal Positional Vertigo (BPPV) is the most common cause of vertigo in clinical practice, affecting an estimated 2.4% of adults during their lifetime with a peak incidence between 50 and 70 years of age. Each word in its name is clinically meaningful: Benign — it is not dangerous and does not reflect serious underlying pathology in the vast majority of cases · Paroxysmal — it occurs in brief, intense attacks rather than continuously · Positional — it is consistently triggered by specific head positions rather than occurring randomly · Vertigo — it is a true spinning sensation, not just dizziness or imbalance.
BPPV is the most common cause of vertigo, affecting approximately 2.4% of adults over their lifetime with peak incidence at 50–70 years. Each word describes the condition: Benign (not dangerous), Paroxysmal (brief attacks, not continuous), Positional (consistently triggered by head position, not random), Vertigo (true spinning, not just dizziness). BPPV is caused by displacement of otoconia — calcium carbonate crystals from the utricle — into a semicircular canal. The posterior canal is affected in 85–90% of cases; the horizontal canal in 10–15%. When the head moves in the plane of the affected canal, the displaced otoconia create an abnormal fluid current, producing a brief but intensely disorienting spinning sensation and nystagmus. Diagnosis: Dix-Hallpike test (posterior canal) produces upbeat-torsional nystagmus toward the affected ear, with a 2–5 second latency, lasting <60 seconds, and reversing on sitting up. Roll test (horizontal canal) for horizontal nystagmus. Treatment: Epley canalith repositioning manoeuvre for posterior canal BPPV — >90% success rate in 1–3 sessions at KIMS. Recurrence: 30% at 1 year; Vitamin D supplementation in deficient patients reduces recurrence.
- Canalithiasis vs cupulolithiasis
- Two mechanical subtypes produce different nystagmus patterns. Canalithiasis (most common): free-floating otoconia create a fluid current — nystagmus is brief (<60 seconds), latent, fatigable, and reverses on sitting up. Cupulolithiasis: otoconia adhere to the cupula, making it gravity-sensitive — nystagmus is persistent and non-fatigable. More commonly produces the ageotropic pattern in horizontal canal BPPV.
- Dix-Hallpike test — the diagnostic standard
- Patient sits upright; examiner turns head 45° toward suspected ear; patient rapidly lowered to lying with head hanging 20–30° below horizontal. Positive in posterior canal BPPV: after 2–5 second latency, upbeat-torsional nystagmus appears (superior pole of eyes beats toward the affected, now-lower ear), lasting 10–30 seconds and reversing briefly on sitting up. Pathognomonic. If Dix-Hallpike is negative — or nystagmus is direction-changing, purely vertical, or non-fatigable — central pathology must be considered.
- The Epley manoeuvre — >90% success
- The Epley canalith repositioning manoeuvre moves displaced otoconia out of the posterior semicircular canal back into the utricle through four head-position changes (about 10–15 minutes). Success rate: >90% resolution in 1–3 clinic sessions. At KIMS the Epley is performed immediately after the Dix-Hallpike confirms the diagnosis — same-visit diagnosis and treatment. Semont manoeuvre is an alternative; a modified Epley can be taught for home self-treatment of recurrent BPPV.
- Horizontal canal BPPV — Roll test and different manoeuvres
- Roll test: supine, head turned rapidly 90° to one side, then the other. Geotropic nystagmus (beating toward the floor in both positions) = canalithiasis of horizontal canal (stronger nystagmus identifies the affected side). Ageotropic nystagmus (beating away from the floor) = cupulolithiasis. Treatment: Geotropic — BBQ roll (360° rotation toward the affected ear); Ageotropic — Gufoni manoeuvre. Horizontal canal BPPV is often more intense and can be misidentified as vestibular neuritis.
- Recurrence and Vitamin D — long-term management
- BPPV recurs in approximately 30% at 1 year and 50% at 5 years. Each recurrence responds to the same Epley manoeuvre. Vitamin D deficiency is a major risk factor for recurrence; supplementation in deficient patients significantly reduces recurrence. At KIMS, serum Vitamin D is checked in all BPPV patients with recurrent episodes. India: Vitamin D deficiency is highly prevalent even in a sun-rich climate due to sun avoidance, clothing practices, and skin pigmentation reducing cutaneous synthesis.
- When BPPV is not BPPV — the red flags
- Do not diagnose BPPV when: vertigo is not strictly positional; nystagmus lacks the characteristic latency and fatigability; there is associated hearing loss (suggests Menière's or labyrinthitis); or there are focal neurological symptoms (headache, double vision, slurred speech, facial asymmetry, limb weakness). The most important BPPV misdiagnosis: a posterior-fossa stroke presenting with positional vertigo being labelled BPPV without a HINTS exam. At KIMS, HINTS is mandatory whenever BPPV cannot be confirmed with absolute confidence by the positional nystagmus characteristics.
- AAO-HNS guideline (2017) — repositioning first, no routine drugs or scans
- India note — Epley by trained clinician vs branded medications
- In India, a significant proportion of patients diagnosed with BPPV receive branded anti-vertigo medications (flunarizine, cinnarizine, prochlorperazine, betahistine) for months to years without an Epley manoeuvre ever being performed. These medications suppress vestibular symptoms without resolving the underlying canal displacement. The Epley manoeuvre performed by a trained clinician at KIMS resolves BPPV immediately in the majority of cases — one appointment, not months of medication.

Benign Paroxysmal Positional Vertigo — A Mechanical Inner-Ear Disorder With a Mechanical Solution
Benign Paroxysmal Positional Vertigo (BPPV) is the most common cause of vertigo in clinical practice, affecting an estimated 2.4% of adults during their lifetime with a peak incidence between 50 and 70 years of age. Each word in its name is clinically meaningful: Benign — it is not dangerous and does not reflect serious underlying pathology in the vast majority of cases · Paroxysmal — it occurs in brief, intense attacks rather than continuously · Positional — it is consistently triggered by specific head positions rather than occurring randomly · Vertigo — it is a true spinning sensation, not just dizziness or imbalance.
BPPV is caused by the displacement of otoconia — small calcium carbonate crystals that normally sit in the utricle of the inner ear, contributing to the detection of linear acceleration and gravity — into one of the three semicircular canals. The most commonly affected canal is the posterior semicircular canal (approximately 85–90% of BPPV cases). The pathophysiology is mechanical: when the head moves in the plane of the affected canal, the displaced otoconia create an abnormal fluid current that triggers a false signal of rotation, producing the brief but intensely disorienting spinning sensation and nystagmus.

Understanding BPPV
The otoconia and their role in balance
The inner ear contains two specialised organs — the utricle and saccule — that detect head position relative to gravity. These organs are lined with hair cells covered by a gelatinous membrane containing thousands of otoconia: tiny calcium carbonate crystals approximately 1–10 micrometres in diameter. When the head moves linearly or tilts, the otoconia — being denser than the surrounding endolymph — exert a gravitational force on the hair cells, producing a neural signal that the brain interprets as linear movement or tilt. Normally, the otoconia are held firmly in the otolithic membrane. When, through head trauma, dehydration, prolonged horizontal positioning, age-related degeneration, or other causes, some otoconia detach and migrate into a semicircular canal, they create an abnormal stimulus whenever the head moves in that canal's plane.
Canalithiasis vs cupulolithiasis — why the nystagmus behaves differently
Two mechanical subtypes of BPPV produce different nystagmus patterns: Canalithiasis (most common): free-floating otoconia move through the endolymph of the semicircular canal when the head moves. They create a fluid current that persists until the crystals settle — typically 5–60 seconds. This produces the characteristic brief, latent, fatigable nystagmus of typical posterior canal BPPV. Cupulolithiasis (less common): otoconia adhere to the cupula (the gelatinous sail of hair cells at the end of the canal). This makes the cupula gravity-sensitive (it is normally not sensitive to gravity). This produces a persistent, non-fatigable nystagmus as long as the head remains in the provocative position — and is more commonly associated with horizontal canal BPPV.
The Dix-Hallpike test — diagnosis in 90 seconds
The Dix-Hallpike test is the gold standard for diagnosing posterior canal BPPV. Procedure: the patient sits upright on the examination couch. The examiner turns the patient's head 45° toward the suspected side (the side of the affected posterior canal). The patient is then rapidly lowered to a supine position with the head hanging 20–30° below horizontal. The examiner observes the patient's eyes for nystagmus and asks about vertigo. Positive result in posterior canal BPPV: after a brief latency (2–5 seconds), upbeat-torsional nystagmus appears (the superior pole of the eyes beats toward the ground — i.e., toward the affected ear when the affected ear is down). The nystagmus typically lasts 10–30 seconds and then resolves. When the patient sits back up, a brief reversal of nystagmus occurs. The test is repeated on the other side to identify the affected ear.
The Roll test — for horizontal canal BPPV
The Roll test (or Supine Roll test / Pagnini-McClure test) is used when horizontal canal BPPV is suspected. Procedure: the patient lies supine with the head elevated 30° (to align the horizontal canal with gravity). The examiner rapidly turns the head 90° to one side, observes nystagmus, returns to centre, then turns 90° to the other side, and observes again. Geotropic horizontal nystagmus (beating toward the ground, toward the lower ear) — the affected ear is the one that produces the stronger nystagmus · Ageotropic horizontal nystagmus (beating away from the lower ear, toward the ceiling) — suggests cupulolithiasis of the horizontal canal · The side with the more intense nystagmus identifies the affected canal.
Treatment at KIMS
BPPV is diagnosed and treated at KIMS through a structured workflow that begins with same-visit confirmation by the Dix-Hallpike or Roll test, proceeds immediately into canal-specific repositioning — the Epley manoeuvre for posterior canal BPPV (over 90% success), the Semont liberatory manoeuvre as an alternative, and the BBQ (Lempert) roll for horizontal canal BPPV — and addresses long-term recurrence with vitamin D measurement and supplementation where deficient :
Epley canalith repositioning manoeuvre — posterior canal BPPV
The Epley manoeuvre guides the displaced otoconia through the posterior canal back into the utricle using a sequence of four head positions. The patient's head is moved through each position over approximately 30–60 seconds per position while the otoconia are allowed to settle at each stage. The manoeuvre takes 5–10 minutes in total. Success rate: >90% after 1–3 treatments. At KIMS, the Epley manoeuvre is performed by a trained neurologist or vestibular physiotherapist with VNG confirmation of nystagmus elimination.
Semont manoeuvre — alternative for posterior canal BPPV
The Semont (liberatory) manoeuvre uses two rapid 180° body movements to dislodge and clear posterior canal otoconia. The patient is rapidly moved from sitting to side-lying (affected ear down), held for 1–2 minutes, then rapidly swung through sitting to the opposite side-lying position (affected ear up), held for 1–2 minutes, then slowly returned to sitting. Comparable efficacy to the Epley manoeuvre. Used when the Epley is not tolerated.
BBQ roll (Lempert manoeuvre) — horizontal canal BPPV (geotropic)
The BBQ roll — named because the patient is rolled in four 90° turns like a rotisserie — guides horizontal canal otoconia from the affected canal back to the utricle. Starting supine with the affected ear up, the patient rolls 90° toward the unaffected ear, then a further 90°, then 90° again, with each position held until nystagmus resolves. Less reliable than the Epley (horizontal canal BPPV is inherently more variable), often requiring multiple sessions.
Vestibular suppressants — not first-line, and not routine
The first-line treatment for posterior canal BPPV (the most common form, approximately 80% of cases) is the Epley canalith repositioning manoeuvre — a bedside procedure that guides displaced otoconia out of the affected semicircular canal. The AAO-HNS Clinical Practice Guideline (2017) recommends canalith repositioning as first-line treatment and specifically recommends against the routine use of vestibular suppressants (antihistamines such as meclizine or dimenhydrinate, and benzodiazepines) in BPPV, as these medications do not address the underlying cause — displaced otoconia — and may delay recovery or reduce motivation to undergo repositioning. Vestibular suppressants may be used for short-term symptomatic relief in selected patients, for example where severe nausea prevents the manoeuvre being performed, but they are not the primary treatment.
Imaging and vestibular testing — not routine in typical BPPV
BPPV is a clinical diagnosis confirmed by the Dix-Hallpike test. The AAO-HNS guideline recommends against routine CT/MRI or vestibular function testing when the diagnosis is established by typical clinical features — brief (under 1 minute) positional vertigo triggered by lying down, rolling over, or looking up, together with a positive Dix-Hallpike showing torsional, upbeat nystagmus with latency and fatigability. In that setting, imaging adds no diagnostic value and exposes the patient to unnecessary cost, radiation, and delay. Imaging or additional investigations are reserved for cases with atypical features — nystagmus that does not fatigue, duration exceeding 1 minute, direction-changing or vertical nystagmus, other neurological symptoms — where a central cause must be excluded, or where the diagnosis is in doubt or manoeuvres fail after an appropriate course of treatment.
Vitamin D supplementation — reducing recurrence
Several randomised trials have shown that vitamin D supplementation in BPPV patients with serum 25-OH vitamin D below 20 ng/mL significantly reduces the annual recurrence rate of BPPV. Serum vitamin D is measured at KIMS in all BPPV patients. Supplementation: cholecalciferol 1,000–2,000 IU/day (or higher replacement doses if significantly deficient). Given the high prevalence of vitamin D deficiency in India (affecting 70–80% of the population despite abundant sunshine due to indoor lifestyles, dark skin tone, and dietary patterns), this is a particularly relevant intervention.
