,Section A - Sleep
Q1.
A patient with moderate OSA (AHI 22) is being considered for oral appliance therapy.
Which combination of baseline characteristics most strongly predicts a favorable
therapeutic response to a mandibular advancement device?
A. Central-dominant apneas, high loop gain, B. Positional OSA, low BMI, and
and low arousal threshold predominantly hypopneas
C. Severe OSA with high collapsibility and D. Rapid eye movement
high arousal threshold (REM)-predominant apneas and high BMI
Correct: B - Positional OSA, low BMI, and predominantly hypopneas
Rationale:Positional OSA, low BMI, and predominantly hypopneas are associated with better
oral appliance outcomes due to lower pharyngeal collapsibility and greater responsiveness to
mandibular advancement. Central-dominant apneas, high loop gain, or severe collapsibility
often indicate poor candidacy or need for alternative therapies.
Q2.
During a titration sleep study with a mandibular advancement device, the patient develops
treatment-emergent central sleep apnea with a central apnea index of 12/hour. What is the
most appropriate next step?
A. Increase mandibular protrusion to B. Discontinue oral appliance therapy and
eliminate residual events immediately initiate CPAP
C. Re-evaluate with a split-night study while D. Add supplemental oxygen without
monitoring for resolution altering the appliance setting
Correct: C - Re-evaluate with a split-night study while monitoring for resolution
Rationale:Treatment-emergent central apnea often resolves spontaneously as the patient
acclimates to therapy; re-evaluation is indicated before abandoning treatment. Increasing
protrusion may worsen central events, while immediate CPAP discontinuation is premature,
and oxygen alone does not address the underlying ventilatory instability.
Q3.
A patient with severe OSA (AHI 45) and complete edentulism is being evaluated for oral
appliance therapy. Which factor is the absolute contraindication to a conventional
mandibular advancement device?
A. Insufficient number of remaining teeth for B. Presence of temporomandibular joint
anchorage osteoarthritis
Page 3
, Section A - Sleep
C. History of prior D. Body mass index of 38 kg/m²
uvulopalatopharyngoplasty
Correct: A - Insufficient number of remaining teeth for anchorage
Rationale:Oral appliances require adequate dentition for retention and force distribution;
complete edentulism precludes conventional device use without implant-supported anchors.
TMJ arthritis and prior surgery are relative contraindications, and high BMI is a predictor of
poorer response but not an absolute contraindication.
Q4.
Which of the following physiological mechanisms best explains the reduction in
apnea-hypopnea index observed with mandibular advancement devices?
A. Stimulation of upper airway dilator muscle B. Direct reduction of pharyngeal critical
reflexes via proprioceptive feedback closing pressure through anterior
displacement of the tongue and soft palate
C. Decrease in loop gain by increasing D. Increase in functional residual capacity
ventilatory drive due to altered thoracic geometry
Correct: B - Direct reduction of pharyngeal critical closing pressure through anterior
displacement of the tongue and soft palate
Rationale:Mandibular advancement physically pulls the tongue and soft palate forward,
reducing pharyngeal collapsibility (lowering Pcrit). While muscle reflexes may play a minor
role, the primary mechanism is mechanical. Loop gain is not directly reduced, and lung
volume changes are not a primary effect.
Q5.
A patient using a mandibular advancement device reports new-onset morning jaw pain
and tooth discomfort. Which intervention is most appropriate as first-line management?
A. Discontinue the device permanently and B. Advise use of a bite splint during the day
refer for CPAP to rest the jaw
C. Reduce the amount of mandibular D. Prescribe muscle relaxants to alleviate
protrusion and schedule a follow-up temporomandibular symptoms
Correct: C - Reduce the amount of mandibular protrusion and schedule a follow-up
Rationale:Side effects like jaw pain often resolve with a slight reduction in protrusion,
allowing adaptation. Permanent discontinuation is premature; daytime splints and muscle
relaxants do not address the underlying device adjustment and delay proper management.
