Table 5 Tongue base anteroposterior collapse in positional and non-positional obstructive sleep apnea
From: Role of drug-induced sleep endoscopy in evaluation of positional vs non-positional OSA
Collapse Pattern | Positional OSA (n = 174) | Non-positional OSA (n = 56) | P value* | ||
|---|---|---|---|---|---|
Level | Configuration | Degree | n (% within Position OSA) | n (% within Non-position OSA) | |
Tongue Base | A-P | 0 | 54 (31%) | 8 (14.3%) | 0.003 |
1 | 73 (42%) | 23 (41.1%) | |||
2 | 47 (27%) | 25 (44.6%) | |||
