OBJECTIVE: The objective of this study was to determine the extent to which @entity1184 contributes to the severity of @entity27 ( @entity27 ) in @entity1 . STUDY DESIGN: Thirty-three consecutive @entity1 who were referred to a @entity25 center for evaluation of suspected @entity27 had standard lateral neck roentgenography performed. Adenoid size was determined by measuring the @entity11266 ( @entity11266 ) ratio. Tonsil size was quantitated on physical examination. The severity of @entity27 was determined by full-night polysomnography in the sleep laboratory. RESULTS: All of the @entity1 reported snoring with trouble breathing, @entity386 , or both problems witnessed by a parent. The @entity1 ' respiratory disturbance index ranged from 0 to 95.3 (mean +/- SD 12.5 +/- 9.1). The @entity1 ' @entity11266 ratio ranged from 0.48 to 0.98 (0.76 +/- 0.14); 30 (91%) of the 33 @entity1 had @entity11266 ratios greater than published normal means, and 16 (48%) had @entity11266 ratios more than 2 standard deviations above published means. Although the @entity11266 ratio and tonsil size did not predict the number of @entity386 , a significant relationship was seen between the @entity11266 ratio and the duration of obstructive @entity386 (r = 0.48, p < 0.01). @entity28 (percent ideal body weight) was the only independent predictor for the number of respiratory events per hour of sleep (r = 0.49, p < 0.01). Percent ideal body weight was also the major predictor of the lowest oxyhemoglobin saturation (r = -0.58, p < 0.0001), but the @entity11266 ratio also contributed to the variance in saturation, with a correlation coefficient (r) of 0.69 for the two factors (p < 0.0001). CONCLUSION: @entity706 affects the severity of @entity386 more than the number of obstructive @entity386 . The pathophysiologic characteristics of @entity27 in @entity1 probably involve complex interactions between pharyngeal size and mechanics.

Adenoid size is related to severity but not the number of episodes of obstructive @entity386 in XXXX .
