Abstract:
The cephalometric radiographs of 13 patients without sleep apnea who had undergone isolated maxillary surgery were studied. The authors found increases in both the nasopharyngeal and hypopharyngeal airway spaces 3 to 5 years after surgery. The results suggest that adaptive processes occur in both the upper and lower jaw, which contribute to an enlarged airway after surgery.
