Abstract

OBJECTIVE

To investigate the relationship between the changes of upper airway and genioglossus muscle activity after the treatment with Snoreguard.

METHODS

31 patients with OSAS or snoring were treated with Snoreguard Cephalometric analysis was carried out to compare the changes of the upper airway before and after the treatment. The relationship between the change in morphology and that of genioglossus muscle activity among 22 patients was investigated.

RESULTS

(1) The size of upper airway decreased significantly with Snoreguard. SPP-SPPW increased from (9.14 +/- 3.79) mm to (12.36 +/- 3.74) mm and TB-TPPW increased from (10.63 +/- 3.71) mm to (11.90 +/- 4.33) mm. UC-LC decreased from (21.96 +/- 11.06) mm to (10.48 +/- 8.55) mm and H-MP decreased from (20.60 +/- 6.65) mm to (11.01 +/- 6.84) mm. (2) The size of upper airway in part of the patients decreased with Snoreguard, but good treatment efficiency remained.
