Summary

r Med Dent
Adults with OSA
Is CPAP effective for OSA?
YES! Has been shown more effective than controls and is generally the gold standard with benefits on AHI, ESS, blood pressure, and quality of life (high-quality evidence)
High rate for partial or complete Tx success
Issues of preference / compliance among some patientsDr. S

Adults with OSA
Are MADs effective for OSA?
YES! More effective against controls (high-quality evidence). Compared to CPAP: somewhat less (AHI) or equally effective (ESS, blood pressure, quality of life) (low-quality evidence)
Have on average lower rate for Tx success than CPAP, especially for patients with severe OSA
Might be more easily acceptable than CPAP, but could lead to long-term duration-dependent intraoral (dental) changes

u, DDS, D
r Med Dent
Adults with OSA
Is surgery effective for OSA?
MMA might be equally effective in treating patients with severe OSA, but only one trial exists with spurious data (low quality evidence)
There is no (robust) evidence to support surgically assisted RME or skeletal distraction.
Dr. Spyro

u, DDS, D
r Med Dent
Adults with OSA
What other treatments exist for OSA?
Some evidence exists for the efficacy of(i) oral pressure therapy
(ii) positional therapy
(iii) tongue stabilizing devices
(iv) lifestyle modification (weight loss)
(v) exercise, and
(vi) cervicomandibular support collars
Evidence however is meager and should be confirmed by future research
Dr. Spyro

u, DDS, D
r Med Dent
Children with OSA
Which treatments exist for OSA children?
CPAP could be extrapolated as a good option to treat children with OSA, but evidence is limited
MADs might be effective against OSA in children (few high-quality trials) +effects on tonsils
The use of RME for children with OSA is most supported by low-quality studies. One randomized trial found no grounds for its use.
Dr. Spyro
s Papageorgio
u, DDS, D
r Med Dent
Children with OSA
Which treatments exist for OSA children?
Surgical interventions like adenotonsillectomy have been shown to be effective for children with OSA (few high-quality trials)
Careful identification of Tx candidates is important, since OSA might resolve spontaneously for many children
Residual OSA might persist after surgical Tx and further monitoring / Tx might be needed
