Comparison of Patient Characteristics Between Individuals With Versus Without Severe Supraglottic Airway Collapse.

Characteristic	Severe Supraglottic Collapse, n = 26	No Severe Supraglottic Collapse, n = 8	P Value	Test
BMI, kg/m² (SD)	34.5 (8.2)	33.4 (6.0)	.737	Student t
Age, yr (SD)	49 (2.2)	46 (10.5)	.522	Student t
Male, no. (%)	20 (76.9)	5 (62.5)	.649	Fisher exact
Retrolingual AP collapse, no. (%)	21 (80.8)	2 (33.3)	.007	Fisher exact
Preoperative AHI, events/hr (SD)	43.1 (32.0)	36.3 (23.1)	.876	Mann-Whitney
Surgical success, %	46.2	87.5	.046	Fisher exact

BMI = body mass index; SD = standard deviation; AP = anteroposterior; AHI = apnea-hypopnea index.
