Abstract:
Objective To investigate the upper airway caliber and the corresponding pharyngeal wall in obstructive sleep apnea syndrome(OSAS) by spiral CT.Methods Seven patients with OSAS confirmed by polysomnography(PSG) underwent spiral CT scan.The thickness of posterior pharyngeal wall of retropalatal region(RP),retroglossal region(RG) and epiglottal region(EPG) were measured.Results ①Among 7 patients,5 had only RP obstruction,and 2 had RP and RG regions obstruction;②The length and width of soft palate were 44.28 mm?1.16 mm(normally 41.90 mm?1.95 mm) and 9.42 mm?0.46 mm(normally 5.84 mm?0.24 mm) respectively;③In OSAS patients,the thickness of posterior pharyngeal wall of RP,RG and EPG region were statistically larger than that of the normal group.Conclusion Spiral CT is of practical value in evaluating the pharyngeal airway obstruction of OSAS.
