Table 1

Comparison between pre- and post-op BMI, polysomnographics, and cephalometrics measurements.

	Normal values	Pre-op	Post-op
BMI (kg/m^2)	18.5–24.9
PSG
RDI (hr)
ODI (%)
AHI (events/hr)	<5
L-cephalometry
SNA (°)
SNB (°)
MP-H (mm)
PAS (mm)

PSG, polysomnography recordings; BMI, body mass index; RDI, respiratory disturbance index; ODI, oxygen desaturation index; AHI, apnea-hypopnea index; SNA, angle from Sella-Nasion-point A; SNB, angle from Sella-Nasion-point B; MP-H, distance from mandibular plane to hyoid bone; PAS, posterior airway space.
