Table 2

Anatomical measures from 3D CT before and after uvulopalatopharyngoplasty.

Patient		3D CT
		Diameter (mm)		Air volume (mL)
		Pre-	Post-	Pre -	Post-
1	T	6.4	25.2	19.59	21.34
	A-P	27.8	17.6
2	T	13.2	19.3	8.78	9.03
	A-P	14.8	12.1
3	T	12.8	19.0	10.39	11.53

3D CT = three-dimension computed tomography; A-P = anterior-posterior; OSAS = obstructive sleep apnea syndrome; pre- = preoperatively; post- = postoperatively; T = transverse.
