Benign Paroxysmal Positional Vertigo Indian Medical PG Practice Questions and MCQs
Question 1: A 60-year-old man presents to his primary care physician complaining that he often feels as if the room is spinning when he gets up from a recumbent position or turns his head. He has not lost consciousness and has had no chest pain. He has no cardiac history, and a recent treadmill test showed no abnormalities. On examination, the sensation can be produced by rapidly turning the head. It can be reproduced many times, but it eventually ceases. Nystagmus is elicited. Hearing is normal. Which of the following is the MOST likely mechanism for this patient's symptoms?
- A. Insufficient cerebral perfusion
- B. Insufficient cardiac output
- C. Aberrant stimulation of hair cells (Correct Answer)
- D. Hair cell death in the semicircular canals
Explanation: ***Aberrant stimulation of hair cells*** - The symptoms of **positional vertigo** (room spinning with head movements) and fatigable nystagmus without hearing loss are characteristic of **benign paroxysmal positional vertigo (BPPV)**. - BPPV is caused by dislodged **otoconia** (calcium carbonate crystals) from the utricle that enter the semicircular canals, leading to inappropriate stimulation of the **hair cells** during head movements. *Insufficient cerebral perfusion* - While inadequate cerebral perfusion can cause dizziness or lightheadedness, it typically presents as **presyncope** or orthostatic hypotension, not the rotatory sensation of vertigo. - The patient's symptoms are specifically triggered by head movements and are not associated with changes in body position leading to systemic hypotension. *Insufficient cardiac output* - Insufficient cardiac output can lead to generalized weakness, lightheadedness, or syncope, but it rarely causes the specific sensation of **spinning vertigo** or movement-induced **nystagmus**. - The patient's recent **normal treadmill test** and lack of cardiac history make primary cardiac issues an unlikely cause for these specific symptoms. *Hair cell death in the semicircular canals* - **Hair cell death** would typically result in a permanent or persistent deficit, not a transient, positional vertigo that can be reproduced but eventually ceases (fatigues). - Conditions involving hair cell damage, such as **Meniere's disease** or **labyrinthitis**, often present with additional symptoms like hearing loss or tinnitus, which are absent in this patient.
Question 2: A 25-year-old woman presents with episodes of dizziness, tinnitus, and hearing loss in the right ear. What is the most likely diagnosis?
- A. Labyrinthitis
- B. Ménière's disease (Correct Answer)
- C. Acoustic neuroma
- D. Benign paroxysmal positional vertigo
Explanation: ***Ménière's disease*** - This condition is characterized by a classic triad of **episodic vertigo (dizziness)**, fluctuating **sensorineural hearing loss**, and **tinnitus**, often accompanied by aural fullness, typically affecting one ear. - The symptoms arise from an accumulation of **endolymph** in the inner ear, leading to increased pressure and dysfunction. *Labyrinthitis* - **Labyrinthitis** is an inflammation of the inner ear, usually viral, causing sudden, severe **vertigo** potentially with hearing loss and tinnitus. - Unlike Meniere's disease, **hearing loss** and **tinnitus** in labyrinthitis are usually constant rather than episodic or fluctuating. *Acoustic neuroma* - An **acoustic neuroma** (vestibular schwannoma) is a benign tumor on the eighth cranial nerve, often causing **gradual, progressive unilateral hearing loss**, tinnitus, and **balance issues**, but typically not episodic severe dizziness. - While it can cause hearing loss and tinnitus, the **episodic nature of vertigo** is less common than in Ménière's disease. *Benign paroxysmal positional vertigo* - **BPPV** is characterized by sudden, **brief episodes of vertigo** triggered by specific head movements, caused by dislodged **otoconia** in the semicircular canals. - Critically, BPPV does **not** typically cause associated **hearing loss or tinnitus**, which are prominent symptoms in the presented case.
Question 3: Epley's maneuver is done in:
- A. CSOM
- B. ASOM
- C. Otosclerosis
- D. Positional vertigo (Correct Answer)
Explanation: ***Positional vertigo*** - The **Epley's maneuver** is a highly effective treatment used to reposition **otoconia** (calcium carbonate crystals) that have dislodged into the semicircular canals. - This maneuver helps to resolve the symptoms of **benign paroxysmal positional vertigo (BPPV)**, which is characterized by brief periods of vertigo triggered by specific head movements. *CSOM* - **Chronic suppurative otitis media (CSOM)** refers to chronic infection and inflammation of the middle ear and mastoid. - Treatment typically involves **antibiotics**, **otological surgery**, or topical preparations, not maneuvers to reposition otoconia. *ASOM* - **Acute suppurative otitis media (ASOM)** is an acute infection of the middle ear. - Its management focuses on **antibiotic therapy** and sometimes myringotomy; physical maneuvers like Epley's are not applicable. *Otosclerosis* - **Otosclerosis** is a condition involving abnormal bone growth in the middle ear, leading to conductive hearing loss. - Treatment often involves **stapedectomy** (surgical replacement of the stapes bone) or **hearing aids**, not canalith repositioning maneuvers.
Question 4: Hallpike maneuver is done for:
- A. Vestibular function (Correct Answer)
- B. Cochlear function
- C. Audiometry
- D. Corneal test
Explanation: ***Vestibular function*** - The **Dix-Hallpike maneuver** is a diagnostic test used to identify **benign paroxysmal positional vertigo (BPPV)**, which is a common cause of dizziness originating from the **vestibular system**. - It involves specific head and body movements to provoke dizziness and observe characteristic eye movements (**nystagmus**) indicative of otolith displacement within the semicircular canals. *Cochlear function* - **Cochlear function** relates to hearing and sound perception, which is assessed by tests like **audiometry** or otoacoustic emissions. - The Hallpike maneuver does not directly evaluate the function of the **cochlea**. *Audiometry* - **Audiometry** is a test used to assess a person's **hearing sensitivity** by measuring their ability to hear sounds of different frequencies and intensities. - It is distinct from the Hallpike maneuver, which focuses on **balance** and **vestibular dysfunction**. *Corneal test* - The **corneal reflex test** evaluates the integrity of the **trigeminal (CN V)** and **facial (CN VII)** nerves by observing an involuntary blink response to corneal stimulation. - This test is unrelated to vertigo or the **vestibular system**, which the Hallpike maneuver addresses.
Question 5: A person presenting to the outpatient department with complaints of rotational vertigo and nausea in the morning, which worsens with changes in head position. What is your diagnosis?
- A. Labyrinthitis
- B. BPPV (Correct Answer)
- C. Vestibular neuronitis
- D. Meniere's disease
Explanation: ***BPPV (Benign Paroxysmal Positional Vertigo)*** - **Rotational vertigo** that is triggered by specific **head position changes** and often noticed upon waking or turning in bed is highly characteristic of BPPV. - The symptoms are typically brief, intense, and associated with **nausea**, resolving within seconds to minutes. *Labyrinthitis* - Labyrinthitis presents with **continuous vertigo** and often includes **hearing loss** and **tinnitus**, which are not mentioned in the patient's symptoms. - The vertigo in labyrinthitis is usually constant, not positional, and is caused by inflammation of the inner ear. *Vestibular neuronitis* - Vestibular neuronitis is characterized by **sudden, severe, and persistent vertigo** without hearing loss, often following a viral infection. - Unlike BPPV, the vertigo does not primarily worsen with specific head position changes but is more constant. *Meniere's disease* - Meniere's disease involves a classic triad of **recurrent episodes of vertigo**, **tinnitus**, and **fluctuating sensorineural hearing loss**, often accompanied by aural fullness. - The vertigo attacks are typically severe and last for hours, which is longer than the brief episodes seen in BPPV.
Question 6: Epley's maneuver is used in the treatment of:
- A. BPPV (Benign paroxysmal positional vertigo) (Correct Answer)
- B. Infective labyrinthitis
- C. Cervical spondylosis
- D. Tinnitus
Explanation: ***BPPV (Benign paroxysmal positional vertigo)*** - The **Epley's maneuver** is a repositioning procedure specifically designed to treat **benign paroxysmal positional vertigo (BPPV)** by moving displaced otoconia out of the semicircular canals. - BPPV is characterized by brief episodes of **vertigo** triggered by specific head movements. *Infective labyrinthitis* - **Infective labyrinthitis** is an inflammation of the inner ear, typically caused by a viral or bacterial infection, leading to vertigo, hearing loss, and tinnitus. - Its treatment involves antibiotics or antivirals and symptomatic relief, not physical maneuvers. *Cervical spondylosis* - **Cervical spondylosis** is a degenerative condition affecting the neck vertebrae and discs, causing neck pain, stiffness, and sometimes neurological symptoms. - Treatment focuses on physical therapy, pain management, and sometimes surgery, not the Epley's maneuver. *Tinnitus* - **Tinnitus** is the perception of noise or ringing in the ears without an external source, often a symptom of an underlying condition. - Management involves addressing the underlying cause, sound therapy, and cognitive behavioral therapy, with no role for the Epley's maneuver.
Question 7: A fifty-year-old man, presents to his local physician complaining that he often feels as if the room is spinning when he gets up from a recumbent position or turns his head. He has not lost consciousness and has had no chest pain. He has no cardiac history and a recent treadmill test showed no abnormalities. On examination, the sensation can be produced by rapidly turning the head. It can be reproduced many times, but it eventually ceases. Nystagmus is elicited. Hearing is normal. Which of the following is the most likely mechanism for this patient's symptoms?
- A. Insufficient cerebral perfusion
- B. Insufficient cardiac output
- C. Aberrant stimulation of hair cells (Correct Answer)
- D. Hair cell death in the semicircular canals
Explanation: **Aberrant stimulation of hair cells** - The symptoms described (room spinning sensation upon head movement or rising, fatiguable nystagmus, normal hearing) are classic for **Benign Paroxysmal Positional Vertigo (BPPV)**. - BPPV is caused by dislodged **otoconia** (calcium carbonate crystals) from the utricle migrating into one of the semicircular canals, most commonly the posterior canal. These otoconia then aberrantly stimulate the hair cells within the cupula in response to gravity and head movements. *Insufficient cerebral perfusion* - This would typically cause **presyncope or syncope**, characterized by lightheadedness, blurred vision, or loss of consciousness, not a spinning sensation. - The patient explicitly states he has not lost consciousness. *Insufficient cardiac output* - This would also primarily lead to **presyncope or syncope** due to inadequate blood flow to the brain, manifesting as lightheadedness, dizziness, and potential fainting. - The patient has no cardiac history, a normal treadmill test, and denies chest pain, making cardiovascular causes less likely. *Hair cell death in the semicircular canals* - **Hair cell death** in the semicircular canals would more likely result in a **persistent deficit** in balance, rather than a positional vertigo that can be reproduced and then ceases (fatigue). - Conditions causing hair cell death, such as Meniere's disease, would typically also involve hearing loss or tinnitus, which are absent in this patient.
Question 8: A patient with cholesteatoma has lateral semicircular canal fistula. The most specific sign is:
- A. Head thrust test
- B. Fistula test (Correct Answer)
- C. Hennebert's sign
- D. Dix-Hallpike test
Explanation: ***Fistula test*** - The **fistula test** (Positive pressure test or Hennebert's test) directly assesses for a communication between the middle ear and the labyrinth by applying positive or negative pressure to the external auditory canal. - A positive result, indicated by **nystagmus** or **vertigo** induced by pressure changes, is the **most specific sign** for a **labyrinthine fistula** in the context of **cholesteatoma**. - The lateral semicircular canal is the most commonly affected site in cholesteatoma-related fistulae. *Hennebert's sign* - **Hennebert's sign** refers to **nystagmus** or **vertigo** induced by pressure changes in the external auditory canal **in the absence of an actual fistula**. - It represents a **false positive fistula test** and is classically associated with **congenital syphilis**, **Meniere's disease**, or other conditions causing increased labyrinthine membrane mobility. - In this case with a **confirmed fistula**, the positive pressure test would be called a **positive fistula test**, not Hennebert's sign. *Head thrust test* - The **head thrust test** evaluates the function of the **vestibulo-ocular reflex (VOR)** and is used to detect **peripheral vestibular hypofunction**. - While cholesteatoma can affect vestibular function, this test is **not specific** for identifying a **labyrinthine fistula**. *Dix-Hallpike test* - The **Dix-Hallpike test** is used to diagnose **Benign Paroxysmal Positional Vertigo (BPPV)** by identifying nystagmus and vertigo triggered by specific head positions. - This test detects **otoconia displacement** in the semicircular canals and is **not relevant** for identifying a **labyrinthine fistula**.
Question 9: A person presented to OPD with complaints of rotatory vertigo and nausea in the morning on change in position of the head. What is your diagnosis?
- A. BPPV (Correct Answer)
- B. Meniere's disease
- C. Vestibular neuronitis
- D. Labyrinthitis
Explanation: ***BPPV (Benign Paroxysmal Positional Vertigo)*** - The symptoms of **rotatory vertigo** and **nausea** that occur specifically with **changes in head position** (e.g., getting out of bed in the morning) are classic for BPPV. - BPPV is caused by the displacement of **otoconia** (calcium carbonate crystals) into one of the semicircular canals, typically the posterior canal. *Meniere's disease* - Characterized by a **triad of symptoms**: episodic vertigo, tinnitus (ringing in the ears), and fluctuating sensorineural hearing loss. - The vertigo in Meniere's disease is spontaneous and not typically triggered solely by specific head movements. *Vestibular neuronitis* - Presents as a **sudden onset, severe, persistent vertigo** often accompanied by nausea and vomiting, but without hearing loss. - Unlike BPPV, the vertigo is continuous for days and not solely precipitated by head position changes. *Labyrinthitis* - Similar to vestibular neuronitis but also involves **hearing loss** and/or tinnitus due to inflammation of the entire labyrinth. - The vertigo is continuous and severe, not intermittent or position-dependent like in BPPV.
Question 10: Best surgery to relieve intractable vertigo in a Meniere's disease patient with profound hearing loss is?
- A. Vestibular neurectomy
- B. Endolymphatic sac decompression
- C. Cochleosacculotomy
- D. Surgical Labyrinthectomy (Correct Answer)
Explanation: **Surgical Labyrinthectomy** * **Labyrinthectomy** is the most effective surgical option for intractable vertigo in Meniere's disease when the affected ear also has **profound hearing loss**, as it completely ablates the vestibular function of the inner ear. * Since the patient already has profound hearing loss, the loss of residual hearing from this procedure is not a significant concern, making it an ideal choice for **vertigo control**. *Vestibular neurectomy* * **Vestibular neurectomy** is a highly effective procedure for intractable vertigo, as it aims to selectively cut the vestibular nerve while preserving hearing. * However, it is a more complex surgical approach compared to labyrinthectomy and is typically reserved for patients with **serviceable hearing** that they wish to preserve. *Endolymphatic sac decompression* * **Endolymphatic sac decompression** is a surgical procedure designed to improve the reabsorption of endolymph, thereby reducing the pressure and symptoms of Meniere's disease, including vertigo and hearing loss. * While it may improve vertigo symptoms, it is less consistently effective than ablative procedures for intractable vertigo and its primary benefit is to **preserve hearing**, which is not a priority in a patient with profound hearing loss. *Cochleosacculotomy* * **Cochleosacculotomy** involves making a small opening in the labyrinth to drain endolymph, aiming to reduce endolymphatic hydrops and alleviate vertigo. * Though it can help with vertigo, it carries a high risk of causing complete hearing loss in the operated ear and offers less reliable vertigo control compared to a labyrinthectomy, especially when profound hearing loss is already present.
