Ménière's Disease Indian Medical PG Practice Questions and MCQs
Question 1: What is the condition characterized by an abnormal accumulation of endolymph fluid in the inner ear, leading to symptoms such as vertigo, tinnitus, and hearing loss?
- A. Meniere's disease (Correct Answer)
- B. Monoaural Diplacusis
- C. Lermoyez Syndrome
- D. Otosclerosis
Explanation: ***Meniere's disease*** - This condition is precisely defined by the **triad of symptoms**: episodic **vertigo**, **tinnitus**, and fluctuating sensorineural **hearing loss**, all resulting from **endolymphatic hydrops** (abnormal accumulation of endolymph in the inner ear). - The excess fluid in the **membranous labyrinth** disrupts the normal function of the vestibular and cochlear systems. *Monoaural Diplacusis* - This refers to a phenomenon where an individual perceives a single sound as having a **different pitch or timbre** in the same ear, often a symptom rather than a disease itself. - It does not involve the characteristic triad of vertigo, tinnitus, and hearing loss caused by endolymphatic hydrops. *Lermoyez Syndrome* - This is a rare variant of Meniere's disease where **hearing loss and tinnitus precede** and gradually worsen before an episode of vertigo, with hearing often improving after the vertigo attack. - While related to endolymphatic hydrops, the **temporal sequence** of symptoms is distinct from classic Meniere's disease. *Otosclerosis* - This is a condition involving abnormal bone growth in the **middle ear**, specifically around the **stapes bone**, leading to **conductive hearing loss**. - While it causes hearing loss, it is not characterized by endolymphatic hydrops, vertigo, or tinnitus as primary symptoms, unlike Meniere's disease.
Question 2: Differential diagnosis of Meniere's disease includes all except -
- A. Acoustic neuroma
- B. Suppurative otitis media (Correct Answer)
- C. CNS disease
- D. Labyrinthitis
Explanation: ***Suppurative otitis media*** - **Suppurative otitis media** is an **infection of the middle ear** causing pus formation, earache, and hearing loss, which is distinctly different from the inner ear disorder seen in Meniere's disease. - Its clinical presentation, including visible **tympanic membrane perforation** and **otorrhea**, does not mimic the classic Meniere's triad of episodic vertigo, tinnitus, and fluctuating hearing loss. *Acoustic neuroma* - This is a **benign tumor** on the **vestibulocochlear nerve** that can cause progressive unilateral hearing loss, tinnitus, and balance issues, similar in some ways to Meniere's. - However, the hearing loss is typically **slowly progressive** and not fluctuating episodically like in Meniere's disease. *CNS disease* - Various **central nervous system (CNS) conditions**, such as **migraine-associated vertigo** or **vertebrobasilar insufficiency**, can present with dizziness, balance problems, and even tinnitus. - Unlike Meniere's, these conditions often have additional **neurological deficits** and typically lack the classic triad of episodic vertigo, fluctuating hearing loss, and aural fullness. *Labyrinthitis* - **Labyrinthitis** is an **inflammation of the inner ear** that causes sudden, severe vertigo, nausea, and hearing loss, which can initially resemble a Meniere's attack. - However, labyrinthitis is usually **self-limiting**, resolves over weeks, and does not involve the recurrent, fluctuating symptoms and aural fullness characteristic of Meniere's disease.
Question 3: Surgeries used in management of Meniere's disease are all Except
- A. Sacculotomy
- B. Endolymphatic shunt operation
- C. Stapedectomy (Correct Answer)
- D. Labyrinthectomy
Explanation: ***Stapedectomy*** - **Stapedectomy** is a surgical procedure primarily used to treat **otosclerosis**, a condition causing conductive hearing loss due to abnormal bone growth in the middle ear. - It involves removing the stapes bone and replacing it with a prosthesis to restore sound conduction, which is not a treatment for **Meniere's disease**. *Sacculotomy* - This procedure involves making a small incision in the **saccule** (part of the labyrinth) to decompress the inner ear in Meniere's disease. - Its goal is to reduce inner ear pressure and improve symptoms like **vertigo**, but it carries a risk of hearing loss. *Endolymphatic shunt operation* - This surgery aims to create a drainage path for excess **endolymph** from the endolymphatic sac, reducing pressure in the inner ear. - It is a common surgical option for intractable Meniere's disease to control vertigo attacks while preserving hearing. *Labyrinthectomy* - **Labyrinthectomy** is a destructive surgical procedure where the entire **labyrinth**, including the vestibular and cochlear structures, is removed. - It is typically reserved for severe, intractable Meniere's disease in patients with **non-serviceable hearing** in the affected ear, as it results in complete hearing loss.
Question 4: Chemical labyrinthectomy by transtympanic route is done in Meniere's disease using which drug?
- A. Amikacin
- B. Amoxycillin
- C. Cyclosporine
- D. Gentamicin (Correct Answer)
Explanation: ***Gentamicin*** - **Gentamicin** is an **aminoglycoside antibiotic** that is commonly used for chemical labyrinthectomy due to its **ototoxic** properties, particularly its selective toxicity to **vestibular hair cells** at lower doses. - When administered transtympanically, it achieves high concentrations in the **inner ear fluid**, effectively ablating the vestibular function and reducing severe vertigo in **Meniere's disease**. *Amikacin* - **Amikacin** is also an **aminoglycoside antibiotic** with ototoxic potential, but it is typically reserved for severe bacterial infections and is not the primary drug of choice for **chemical labyrinthectomy** in Meniere's disease. - While it can cause hearing loss, **gentamicin** has a more established and preferential effect on the **vestibular system** at therapeutic doses for Meniere's. *Amoxycillin* - **Amoxycillin** is a common **beta-lactam antibiotic** used for bacterial infections, and it does not possess **ototoxic** properties that would make it suitable for chemical labyrinthectomy. - It is primarily known for its antibacterial action and has no role in the management of vertigo in **Meniere's disease** via transtympanic administration. *Cyclosporine* - **Cyclosporine** is an **immunosuppressant drug** used to prevent organ rejection and treat autoimmune conditions; it does not have properties for chemical ablation of the labyrinth. - While some autoimmune components are sometimes considered in Meniere's disease, cyclosporine is not used for **transtympanic chemical labyrinthectomy**.
Question 5: Which of the following is the most common morbidity associated with Meniere's disease?
- A. Permanent hearing loss (Correct Answer)
- B. Secondary development of a craniopharyngioma
- C. Chronic otitis media
- D. Chronic otitis externa
Explanation: ***Permanent hearing loss*** - **Meniere's disease** is characterized by episodes of **vertigo**, **tinnitus**, ear fullness, and fluctuating hearing loss, which often progresses to permanent hearing loss over time. - The recurrent episodes of **endolymphatic hydrops** cause cumulative damage to the **cochlea** and **vestibular apparatus**, leading to irreversible sensorineural hearing loss. *Chronic otitis media* - This is an **infection** and **inflammation of the middle ear**, typically leading to tympanic membrane perforation or cholesteatoma. - It is distinct from Meniere's disease, which is a disorder of the **inner ear** with no direct pathological link to middle ear infections. *Chronic otitis externa* - This condition involves **inflammation of the external ear canal** and is usually caused by bacterial or fungal infections. - It is an outer ear condition and bears no etiological or symptomatic relationship to the inner ear pathology of Meniere's disease. *Secondary development of a craniopharyngioma* - A **craniopharyngioma** is a benign brain tumor arising from Rathke's pouch cells, typically located near the **pituitary gland**. - There is no known direct association or increased risk of developing a craniopharyngioma in patients with Meniere's disease.
Question 6: Which of the following is NOT seen in Meniere's disease?
- A. Otalgia (Correct Answer)
- B. Tinnitus
- C. Hearing loss
- D. Vertigo
Explanation: ***Otalgia*** - **Otalgia** (ear pain) is **not a typical symptom** of Meniere's disease. Meniere's disease is characterized by an imbalance of fluid in the inner ear, leading to a specific triad of symptoms. - While other ear conditions can cause pain, it is not part of the diagnostic criteria or common presentation of Meniere's. *Tinnitus* - **Tinnitus**, often described as a ringing, buzzing, or roaring sound in the ear, is a **hallmark symptom** of Meniere's disease. - It often accompanies or precedes the vertigo attacks and can fluctuate in intensity. *Hearing loss* - **Fluctuating sensorineural hearing loss**, usually affecting the lower frequencies initially, is a key diagnostic criterion for Meniere's disease. - The hearing loss can worsen during attacks and may become more permanent over time. *Vertigo* - **Episodic rotational vertigo**, often severe and lasting from 20 minutes to several hours, is the most debilitating symptom of Meniere's disease. - It is typically associated with nausea and vomiting and is a core part of the diagnostic criteria.
Question 7: Which of the following is not true about Meniere’s disease?
- A. Fluctuating hearing loss
- B. Bilateral involvement (Correct Answer)
- C. Tinnitus
- D. Vertigo
Explanation: ***Bilateral involvement*** - Meniere's disease **characteristically presents as a unilateral disorder** affecting one ear. - Only **15-30% of patients** eventually develop bilateral involvement, typically occurring **years to decades** after initial presentation. - Since bilateral involvement is **not a typical feature**, this statement is **not true** about Meniere's disease, making it the correct answer. *Fluctuating hearing loss* - **Intermittent and progressive hearing loss** is a hallmark symptom of Meniere's disease, often worsening during acute attacks. - This symptom is due to **endolymphatic hydrops** affecting the cochlea and is part of the classic presentation. *Tinnitus* - **Tinnitus** (ringing, roaring, or buzzing sound) is one of the cardinal symptoms of Meniere's disease. - It typically **worsens during vertiginous episodes** and can fluctuate in intensity between attacks. *Vertigo* - **Recurrent, spontaneous episodes of rotational vertigo** are the defining characteristic of Meniere's disease. - Episodes last from **20 minutes to several hours**, often accompanied by nausea, vomiting, and prostration.
Question 8: All of the following are seen in Meniere's Disease except:
- A. Fullness of ear
- B. Ear Pain (Correct Answer)
- C. Vertigo
- D. Tinnitus
Explanation: ***Ear Pain*** - **Otalgia** (ear pain) is not a typical symptom of **Meniere's disease**. - While patients may experience discomfort due to pressure, sharp or significant pain is generally absent. *Fullness of ear* - A sensation of **aural fullness** or pressure in the affected ear is a characteristic symptom of Meniere's disease, often preceding a vertiginous attack. - This symptom is thought to be due to the buildup of **endolymphatic fluid** within the inner ear. *Vertigo* - **Episodic rotational vertigo** is a hallmark symptom of Meniere's disease, significantly impacting daily activities and often accompanied by nausea and vomiting. - These attacks are typically sudden, severe, and can last from 20 minutes to several hours. *Tinnitus* - **Tinnitus**, often described as a ringing, buzzing, or roaring sound, is a common symptom in patients with Meniere's disease. - It usually fluctuates in intensity and can worsen before or during a vertigo attack.
Question 9: A 72-year-old man presents to his primary care physician with progressively worsening hearing loss. He states that his trouble with hearing began approximately 7-8 years ago. He is able to hear when someone is speaking to him; however, he has difficulty with understanding what is being said, especially when there is background noise. In addition to his current symptoms, he reports a steady ringing in both ears, and at times experiences dizziness. Medical history is significant for three prior episodes of acute otitis media. Family history is notable for his father being diagnosed with cholesteatoma. His temperature is 98.6°F (37°C), blood pressure is 138/88 mmHg, pulse is 74/min, and respirations are 13/min. On physical exam, when a tuning fork is placed in the middle of the patient's forehead, sound is appreciated equally on both ears. When a tuning fork is placed by the external auditory canal and subsequently on the mastoid process, air conduction is greater than bone conduction. Which of the following is most likely the cause of this patient's symptoms?
- A. Stapedial abnormal bone growth
- B. Endolymphatic hydrops
- C. Cochlear hair cell degeneration (Correct Answer)
- D. Accumulation of desquamated keratin debris
Explanation: ***Cochlear hair cell degeneration*** - The patient's **progressive, bilateral hearing loss** over several years, difficulty understanding speech in noise, and **tinnitus** are classic symptoms of **presbycusis**, which results from age-related **degeneration of cochlear hair cells**. - The **normal Weber test** (no lateralization) and **Rinne test** (air conduction > bone conduction) indicate a **sensorineural hearing loss**, consistent with cochlear pathology rather than conductive issues. *Stapedial abnormal bone growth* - This condition (**otosclerosis**) causes **conductive hearing loss** due to fixation of the stapes, which would present with an **abnormal Rinne test** (bone conduction > air conduction) in the affected ear. - While it can cause progressive hearing loss and tinnitus, the normal Rinne test contradicts this diagnosis. *Endolymphatic hydrops* - This is the underlying pathology of **Ménière's disease**, which typically presents with episodic vertigo, fluctuating sensorineural hearing loss, tinnitus, and aural fullness. - The patient's dizziness is non-episodic, and the absence of fluctuating hearing loss and aural fullness makes Ménière's less likely. *Accumulation of desquamated keratin debris* - This describes a **cholesteatoma**, which typically causes **conductive hearing loss** and often presents with otorrhea, earache, and possibly vestibular symptoms. - The normal Rinne test (indicating sensorineural loss) and lack of otorrhea or earache make cholesteatoma unlikely, despite a family history.
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.
