,Section A - Sleep Medicine Fundamentals
Q1.
Which combination of neuromuscular and biomechanical effects best explains the
therapeutic action of mandibular advancement devices in obstructive sleep apnea?
A. Activation of genioglossus and medial B. Inhibition of masseter and increase in
pterygoid velopharyngeal cross-section
C. Stretching of palatoglossus and reduction D. Lengthening of stylohyoid and increased
in pharyngeal critical closing pressure hyoid suspension
Correct: C - Stretching of palatoglossus and reduction in pharyngeal critical closing
pressure
Rationale:
Mandibular advancement devices stretch the tongue and soft palate, increasing
velopharyngeal patency and reducing pharyngeal critical closing pressure. Activation of
genioglossus is secondary, and pterygoid activation is not primary. Stretching of palatoglossus
directly increases airway space.
Q2.
In a randomized crossover trial comparing CPAP and custom mandibular advancement
device for moderate OSA, which finding would most strongly support a role for oral
appliance therapy as a first-line treatment?
A. Similar AHI reduction but higher B. Greater improvement in Epworth
compliance with MAD Sleepiness Scale with CPAP
C. Lower dropout rate with CPAP D. Equivalent blood pressure reduction but
faster titration with MAD
Correct: A - Similar AHI reduction but higher compliance with MAD
Rationale:
Higher compliance with MAD often offsets its slightly inferior efficacy, leading to comparable
effective therapy. Greater symptom improvement or lower dropout with CPAP would favor
CPAP. Faster titration does not outweigh efficacy.
Q3.
During hypoglossal nerve stimulation therapy for obstructive sleep apnea, electrical
stimulation of which branch of the hypoglossal nerve is primarily responsible for tongue
protrusion and airway collapsibility improvement?
A. Medial branch to genioglossus B. Lateral branch to styloglossus
Page 3
, Section A - Sleep Medicine Fundamentals
C. The entire trunk D. The loop to the hyoglossus
Correct: A - Medial branch to genioglossus
Rationale:
The medial branch innervates the genioglossus, the primary protrusor of the tongue.
Stimulation of this branch advances the tongue base, reducing pharyngeal collapsibility.
Lateral branch retracts the tongue.
Q4.
According to the AASM scoring manual (most recent version), which of the following
definitions best characterizes a hypopnea in the context of obstructive sleep apnea
diagnosis?
A. A 30% reduction in airflow lasting 10 B. A 50% reduction in airflow lasting 10
seconds with 3% oxygen desaturation or seconds with 4% oxygen desaturation
arousal
C. A 90% reduction in airflow lasting 10 D. Any reduction in airflow followed by an
seconds with 3% oxygen desaturation arousal or desaturation 2%
Correct: A - A 30% reduction in airflow lasting 10 seconds with 3% oxygen desaturation or
arousal
Rationale:
The AASM recommends a hypopnea as a 30% reduction in airflow for 10 seconds associated
with 3% desaturation or an arousal. Option B is the older Chicago definition, C is an apnea,
and D is too nonspecific.
Q5.
A patient using a mandibular advancement device for 6 months reports new-onset
morning headaches and retro-orbital pressure. Polysomnography shows controlled AHI
<5. What is the most likely cause?
A. Increased intracranial pressure from B. Temporomandibular joint inflammation
device referred to head
C. Occlusal changes leading to muscle D. Device-induced sleep fragmentation
spasm
Correct: C - Occlusal changes leading to muscle spasm
