Table 3 Velum concentric 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) | |
Velum | Concentric | 0 | 64 (36.8%) | 10 (17.9%) | 0.004 |
1 | 7 (4.0%) | 0 (0%) | |||
2 | 103 (59.2%) | 46 (82.1%) | |||
