How does distraction osteogenesis maxillary expansion (DOME) reduce severity of obstructive sleep apnea?

CONCLUSION: Anatomic expansion of the nasal floor with widening of the hard palatal vault from DOME is associated with reduction of nasal airflow velocity and downstream reduction of negative pressure in the pharyngeal airway. This dynamic interaction correlates with a reduction in the apnea-hypopnea index (AHI) and Oxygen Desaturation Index (ODI). PMID: 31823220 [PubMed - as supplied by publisher]
