Q

 is a very common and potentially
life-
threatening medical disorder (i.e. heart

Q

A

17
Q

If a pt has class 4 soft palate, how is airway?

A

No airway space

18
Q
  1. Is REQUIRED by insurance prior to treatment
    (pre-treatment), M.D. must order PSG
  2. Is REQUIRED at end of completion (post-
    treatment) to determine efficacy of oral
    sleep apnea appliance although some
    insurance will accept the home sleep study
  3. May be ordered while titrating appliance or
    a home sleep study may be authorized
A

Polysomnography (PSG)

19
Q

The following are ___ for sleep devices
1. Insufficient teeth to support device however
can be made if 1 arch is edentulous
2. Periodontal problems causing tooth mobility
3. Active temporomandibular joint disorder
(TMD) or severe arthritis
4. Limited maximum protrusion < 6mm
Clark GT. Mandibular advancement devices and sleep disordered
breathing.

A

Contraindications

20
Q

 Splints the upper airway pneumatically during
sleep so airway does NOT collapse
 Highly effective but cumbersome
 Long-term compliance is 60 – 70%

A

CPAP: Continuous positive airway pressure

21
Q

 Surgical removal of uvula with resection of
soft palate tissue to create more space
 50% of patients report improved sleep apnea
symptoms but not always long term
 Surgery to correct deviated septum, nasal
polyps, tonsillectomy and chronic rhinitis may
also help

A

Uvulopalatopharyngoplasty

22
Q

Oral applicances are best for what levels of OSA?

A

MIld/MOdereate

23
Q

MOA of _____
1. Normally made 50-75% of the maximum
protrusion
2. Widening of the airway laterally
3. Relocation of the pharyngeal fat pads
laterally
4. Anterior displacement of the tongue base
5. Protrusion is normally accompanied with
increased vertical dimension

A

Custom oral appliance

24
Q

 Has nylon advancement rods that patient can
change at home
 Less driving and less appointments needed
 No metal

A

Avant sleep apnea device
