title: The influence of maxillary osteotomy on nasal airway patency and geometry.
abstract: Maxillary surgical repositioning affects nasal airway size. This study recorded nasal airway changes by acoustic rhinometry in patients with maxillary surgical repositioning after Le Fort I osteotomies. These changes were compared to the amount of skeletal movement by means of preoperative and 6-week postoperative lateral cephalography. Vertical linear movement of the posterior maxilla showed a very close relationship to volume changes in the posterior nasal segment. Anterior nasal volume changes can not be considered as a pure function of the direction and amount of skeletal movement. The greatest amount of cranial displacement tolerated without impaired nasal patency in this study was 7 mm.
