[The study of the relationship between XXXX and positional nasal resistance].

@entity1 @entity11766 @entity27
OBJECTIVE: To study the nasal resistance in different position and its possible @entity27 ( @entity27 ). METHOD: The positional rhinomanometry and the detection of polysomnography were performed in 14 normal subjects, 20 snoring @entity1 and 40 @entity1 with @entity27 . RESULT: The study reveals that: 1. the nasal resistance in seated position and in supine position of the @entity1 with @entity27 but without @entity11766 or snoring @entity1 without @entity11766 were higher than that of the normal group (P < 0.05). 2. The nasal resistance in seated position and in supine position of the @entity1 with both @entity27 and @entity11766 were higher than that of the snoring @entity1 with @entity11766 (P < 0.05). 3. The nasal resistance in supine position was higher than the nasal resistance in seated position in all the groups (P < 0.05), even in the @entity1 with @entity27 (P < 0.01). 4. The AHI, waken intervals, snoring index of the @entity1 both with @entity27 and @entity11766 were higher than those of the @entity1 only with @entity27 . CONCLUSION: Nasal resistance increased in the @entity1 with snoring or @entity27 and increased more in the supine position. Nasal resistance may be an important factor in the pathogenesis of @entity27 .
