,Section A - Sleep Medicine Fundamentals
Q1.
A patient with moderate obstructive sleep apnea (AHI 22) cannot tolerate CPAP. Which
craniofacial finding is most strongly associated with a favourable response to mandibular
advancement device therapy?
A. Longer maxillary length (ANS-PNS) on B. Higher cranial base flexure
cephalometry (nasion-sella-basion angle >130°)
C. Shorter mandibular body length (Go-Gn) D. Narrower maxillary intermolar width
relative to anterior cranial base (S-N)
Correct: B - Higher cranial base flexure (nasion-sella-basion angle >130°)
Rationale:
A wider cranial base angle (higher N-S-Ba angle) is associated with a more posteriorly
positioned mandible, which allows greater protrusive advancement and thus higher likelihood
of therapeutic success. In contrast, longer maxillary length or narrower maxilla do not
specifically predict OAT response; shorter mandibular length may reduce protrusive capability.
Q2.
During drug-induced sleep endoscopy (DISE), a patient shows complete concentric
collapse at the velum. Which oral appliance modification or alternative therapy is
contraindicated based on this finding?
A. Mandibular advancement device with B. Combination therapy with nasal EPAP
maxillary expansion valve
C. Tongue-retaining device (non-anchored) D. Somnoplasty of the soft palate
Correct: C - Tongue-retaining device (non-anchored)
Rationale:
Concentric collapse is often caused by low palatal tone. A tongue-retaining device can
exacerbate airway collapse by pulling the tongue base forward while the soft palate has no
support, increasing obstruction. An MAD with maxillary expansion can improve
velopharyngeal patency; nasal EPAP bypasses the velum; somnoplasty reduces palatal
tissue and is not contraindicated.
Q3.
A 45-year-old man with severe OSA (AHI 45, BMI 32) has failed CPAP due to mask
claustrophobia. He also has mild daytime sleepiness (ESS 11). He is considering oral
appliance therapy. Based on current guidelines, match each adjunctive intervention with
its appropriateness.

Nonessential
Correct: A - Weight loss: Anticipated; CPAP+OAT: Contraindicated; Surgery:
Nonessential; Positional: Nonessential; O2: Contraindicated; Sleep hygiene: Anticipated
Rationale:
Weight loss is first-line for severe OSA with obesity. CPAP+OAT combination is not routinely
recommended as first rescue. Hypoglossal nerve stimulator is an option after CPAP failure but
not routinely anticipated early. Positional therapy is nonessential if AHI not
position-dependent. Supplemental oxygen is not indicated without nocturnal hypoxemia.
Sleep hygiene is foundational. Thus A matches correct assignments.
Q4.
A patient using a mandibular advancement device has residual AHI 12 (from baseline AHI
40). Polysomnography shows the residual events are predominantly central and
Cheyne-Stokes respiration. What is the most appropriate next step?
A. Increase mandibular protrusion by 1 mm B. Add a tongue retaining feature to the
and repeat PSG appliance
C. Refer for sleep cardiology assessment D. Switch to a CPAP machine set in
and consider adaptive servo-ventilation auto-CPAP mode
Correct: C - Refer for sleep cardiology assessment and consider adaptive
servo-ventilation
Rationale:
Central apnea and Cheyne-Stokes often indicate underlying cardiopulmonary instability (e.g.,
heart failure). Increasing protrusion would not address central events. Adding a tongue
retainer may worsen. Auto-CPAP is not indicated for central sleep apnea. Referral to
cardiology and consideration of ASV is the standard of care for this presentation.
Q5.
In a patient with an edentulous maxilla and partially dentate mandible, which type of oral
appliance is most likely to be effective for OSA therapy?
