Over 85% of patients with Ménière's disease do not show improvement with management strategies like medication and dietary changes.
Answer: False
Explanation: The source indicates that over 85% of patients with Ménière's disease do show improvement with management strategies, contrary to the statement.
Medications used during acute Ménière's episodes are primarily aimed at restoring hearing function.
Answer: False

Endolymphatic sac decompression surgery, such as shunt insertion, has strong evidence supporting its effectiveness in reducing dizziness.
Answer: False
Explanation: While surgical options like endolymphatic sac decompression exist, the evidence supporting their effectiveness in reducing dizziness is considered weak or low-quality.
A risk associated with labyrinthectomy surgery is partial hearing loss in the affected ear.
Answer: False
Explanation: Labyrinthectomy, a destructive procedure, invariably results in complete hearing loss in the affected ear, not partial hearing loss.
Vestibular neurectomy, unlike labyrinthectomy, always results in complete hearing loss in the operated ear.
Answer: False
Explanation: Vestibular neurectomy typically preserves hearing, whereas labyrinthectomy carries the risk of complete hearing loss.
Current clinical evidence strongly justifies the widespread use of betahistine for treating Ménière's disease.
Answer: False
Explanation: While betahistine is commonly used due to its safety profile, current clinical evidence does not strongly justify its widespread use for Ménière's disease, although research continues.
Multiple systematic reviews have concluded that intratympanic steroids provide definitive positive effects for Ménière's disease.
Answer: False
Explanation: Systematic reviews indicate that the data regarding intratympanic steroids for Ménière's disease are insufficient to definitively conclude positive effects.
Transtympanic micropressure pulses have shown strong evidence of effectiveness in treating Ménière's disease according to systematic reviews.
Answer: False
Explanation: Two systematic reviews examining transtympanic micropressure pulses found no evidence to support the use of this technique for treating Ménière's disease.
Medical studies strongly support the use of tympanostomy tubes (ventilation tubes) for treating Ménière's disease, with clear conclusions on effectiveness.
Answer: False
Explanation: While there is tentative evidence for potential benefit from tympanostomy tubes for unsteadiness, overall medical studies do not strongly support their use, and conclusions on effectiveness remain unclear.
Ménière's disease is primarily managed by specialists in dermatology and ophthalmology.
Answer: False
Explanation: Ménière's disease is primarily managed by specialists in otolaryngology (ENT) and neurology, not dermatology or ophthalmology.
Combining betahistine with MAOIs has shown no effect on betahistine's bioavailability or cochlear blood flow in research.
Answer: False
Explanation: Research suggests that combining betahistine with MAOIs may increase betahistine's bioavailability and improve cochlear blood flow, contrary to the statement.
Counseling is recommended for Ménière's disease patients primarily to:
Answer: Manage the psychological distress caused by symptoms.
Explanation: Counseling can be beneficial for patients with Ménière's disease by helping to manage the psychological distress associated with chronic symptoms, which can indirectly impact the condition.
Which surgical approach for endolymphatic sac decompression involves removing the sac?
Answer: Removal of the sac
Explanation: Surgical options for endolymphatic sac decompression include simple decompression, shunt insertion, or the complete removal of the sac.
How does vestibular neurectomy typically differ from labyrinthectomy regarding hearing preservation?
Answer: Vestibular neurectomy often preserves hearing, whereas labyrinthectomy risks hearing loss.
Explanation: Vestibular neurectomy generally preserves hearing, in contrast to labyrinthectomy, which carries a risk of complete hearing loss in the operated ear.
What is the current evidence status for betahistine in treating Ménière's disease?
Answer: Evidence does not strongly justify its use, but research is ongoing.
Explanation: Current clinical evidence does not strongly support the widespread use of betahistine for Ménière's disease, although ongoing research is investigating its potential benefits.
Recent research suggests that combining betahistine with MAOIs may:
Answer: Increase betahistine bioavailability and improve cochlear blood flow.
Explanation: Recent pharmacokinetic experiments indicate that combining betahistine with MAOIs may enhance betahistine's bioavailability and improve cochlear blood flow.
What medical specialties are typically involved in the diagnosis and treatment of Ménière's disease?
Answer: Otolaryngology and Neurology
Explanation: Otolaryngology (ear, nose, and throat) and Neurology are the primary medical specialties involved in the management of Ménière's disease.
