Alterations in nasal respiration and nasal airway size following superior repositioning of the maxilla

摘要: Twenty patients who underwent superior repositioning of the maxilla via Le Fort I down fracture had their respiratory mode and nasal cross-sectional area determined prior to 6 months following surgery. Inductive plethysmography air flow techniques were used in determination these parameters. Prior surgery, five breathers, predominantly six oral-nasal four oral breathers. Nine inadequate airways. Six 14 breathers Sixteen adequate airways, three borderline airways one an airway postsurgically. These findings suggest that by does not adversely affect respiration. Nasal function actually improved 17 20 subjects studied.
