Abstract:
OBJECTIVETo investigate the morphologic changes of upper airway in obstructive sleep apnea and hypopnea syndrome (OSAHS) associated with micrognathism before and after orthognathic surgery and distraction osteogenesis, and subsequently to instruct clinical jobs effectively.
METHODSNine OSAHS patients associated with micrognathism (8 males, 1 female, mean age: 28.6 years) received orthognathic surgery and (or) distraction osteogenesis, and the curative effect was evaluated according to the subjective feelings and PSG. Upper airway structure before and after the treatment was measured by Somatom Sensation 16 CT scanner.
RESULTSAll 9 patients were clinically cured. The transverse length, the cross section area, and especially the sagittal length of the upper airway were obviously increased after the orthognathic surgery. The changes involved mainly in the velopharyngeal region and the laryngopharyngeal region, but not in the laryngopharyngeal region.
CONCLUSIONSThe orthognathic surgery and distraction osteogenesis can treat the OSAHS patients with microgonathism effectively by increasing their velopharyngeal and laryngopharyngeal sagittal length of upper airway.
