Changes of upper airway of obstructive sleep apnea syndrome patients after the treatment of Silensor snoreguard / 华西口腔医学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the changes of upper airway of obstructive sleep apnea syndrome (OSAS) patients after the treatment of Silensor snoreguard.</p><p><b>METHODS</b>42 patients with OSAS were treated with dental appliance. Cephalometric analysis was carried out to compare the changes of upper airway before and after the treatment.</p><p><b>RESULTS</b>SPP-SPPW increased from (9.10 +/- 2.25) mm to (12.24 +/- 2.61) mm. PAS increased from (8.99 +/- 3.20) mm to (11.24 +/- 3.79) mm. CL decreased from (26.26 +/- 6.04) mm to (14.37 +/- 8.14) mm. H-MP decreased from (21.27 +/- 6.12) mm to (12.14 +/- 5.89) mm. V -RGn decreased from (55.15 +/- 5.61) mm to (51.63 +/- 5.87) mm. OPAA increased from (7.01 +/- 1.54) mm2 to (7.85 +/- 1.61) mm2. HPAA increased from (3.02 +/- 0.89) mm2 to (3.61 +/- 1.61)mm2.</p><p><b>CONCLUSION</b>Dental appliance worked with the effect of enlarging upper airway.</p>
