[Cephalometric study of changes in the upper airways after orthognathic surgery. Significance in the management of obstructive sleep apnea syndromes. Apropos of 43 cases].
The aim of this work was to study long-term airways space changes after maxillomandibular osteotomy in order to assess benefit of this surgery in case of obstructive sleep apnea syndrome. Preoperative and postoperative cephalometric airway spaces evaluation of 43 patients (who did not have obstructive sleep apnea) was done. Analysis revealed no charge in velopharyngeal space, lingual-pharyngeal augmentation in case of mandibular advancement. Hyoid bone position was not modified by osteotomy. Signification and interest of this finding for patients with obstructive sleep apnea are discussed through literature data.
