Q1.
A 48-year-old male with severe obstructive sleep apnea (AHI 42) is intolerant to CPAP.
Polysomnography shows a predominance of supine-related hypopneas with a mean
oxygen nadir of 82%. Cephalometric analysis reveals retrognathia and a narrow posterior
airway space (PAS 6 mm). Which oral appliance design is most likely to achieve optimal
therapeutic effect in this patient?
A. Tongue-retaining device with no vertical B. Mandibular advancement device with
opening 70% of maximum protrusion and 5 mm
vertical opening
C. Mandibular advancement device with D. Customized twin-block appliance with no
50% of maximum protrusion and 2 mm vertical adjustment
vertical opening
Correct: B - Mandibular advancement device with 70% of maximum protrusion and 5 mm
vertical opening
Rationale:In severe OSA with retrognathia and narrow PAS, a mandibular advancement
device (MAD) with substantial protrusion (60-80% of maximum) and moderate vertical
opening (5 mm) maximizes pharyngeal airway dilation. Option B provides the necessary
advancement while avoiding excessive opening that could reduce efficacy. Tongue-retaining
devices (A) are less effective for severe OSA. Insufficient protrusion (C) or no vertical
adjustment (D) would not adequately address the anatomical compromise.
Q2.
A patient with moderate OSA (AHI 25) has been using a mandibular advancement device
for 6 months. Follow-up polysomnography shows residual AHI 12 with persistent snoring.
The device is set at 60% of maximum protrusion. Which of the following is the most
appropriate next step?
A. Increase protrusion to 80% of maximum B. Switch to CPAP therapy immediately
and repeat PSG in 3 months
C. Add positional therapy and recommend D. Advance the mandible by 1 mm
weight loss increments weekly until snoring resolves
Correct: A - Increase protrusion to 80% of maximum and repeat PSG in 3 months
Page 3
, Section A - Sleep Medicine Fundamentals AND Physiology
Rationale: Residual AHI >10 with persistent snoring indicates suboptimal response. The
standard titration protocol involves incremental advancement (typically 1 mm per week or
similar) until symptoms improve, followed by confirmatory PSG. Option A reflects appropriate
further advancement with reassessment. Switching to CPAP (B) is premature. Positional
therapy and weight loss (C) are adjunctive but do not address the primary issue of inadequate
protrusion. Weekly self-titration without PSG confirmation (D) is not recommended due to risk
of temporomandibular side effects.
Q3.
A recent meta-analysis compared the efficacy of mandibular advancement devices (MAD)
and continuous positive airway pressure (CPAP) for treating obstructive sleep apnea.
Which statement best characterizes the findings regarding cardiovascular outcomes?
A. CPAP significantly reduces blood B. MAD and CPAP show equivalent effects
pressure compared to MAD, but both are on blood pressure reduction and
superior to no treatment. cardiovascular event rates.
C. MAD is associated with greater reduction D. Neither MAD nor CPAP has been shown
in systolic blood pressure than CPAP in to improve cardiovascular surrogate
mild-to-moderate OSA. markers in randomized trials.
Correct: A - CPAP significantly reduces blood pressure compared to MAD, but both are
superior to no treatment.
Rationale:Meta-analyses consistently demonstrate that CPAP reduces blood pressure more
than MAD, though both are effective compared to controls. CPAP's superiority is attributed to
more complete apnea-hypopnea elimination. Option B is incorrect because CPAP shows
greater blood pressure reduction. Option C is unsupported; MAD does not surpass CPAP in
blood pressure lowering. Option D is false; both therapies improve surrogate markers, with
CPAP showing greater effect.
Q4.
Which of the following mechanisms best explains the increased collapsibility of the upper
airway during sleep in patients with obstructive sleep apnea?
A. Reduced genioglossus muscle activity B. Increased lung volume leading to tracheal
combined with a narrow pharyngeal airway tug
C. Elevated serum bicarbonate causing D. Prolonged inspiratory time due to
central respiratory depression decreased chemosensitivity
Correct: A - Reduced genioglossus muscle activity combined with a narrow pharyngeal
airway
