Palatine tonsil size in obese, overweight, and normal-weight children with sleep-disordered breathing.

OBJECTIVE

To assess palatine tonsil size relative to degree of obesity in children with sleep-disordered breathing (SDB).

STUDY

DESIGN

Case-control study.

SETTING

Tertiary care rhinology clinic.

SUBJECTS AND

METHODS

We compared the subjective and objective tonsil size, including tonsil height (TH), tonsil width (TW), tonsil thickness (TT), tonsil weight (TWt), and tonsil volume (TV), in 26 obese children and 26 age- and gender-matched control children with SDB, and in 29 overweight children and 29 matched controls with SDB.

RESULTS

Despite similar subjective tonsil size in obese and control children, the objective tonsil size, including TH, TW, TT, and TWt, was larger in obese than in control children, and the mean TV was significantly greater in obese than in control children with SDB (8.53 +/- 3.30 mL vs 6.90 +/- 2.05 mL; 95% confidence interval [CI] of the difference 0.03-3.25; P = 0.019). In contrast, mean TV (7.38 +/- 3.43 mL vs 7.65 +/- 1.97 mL; 95% CI -1.92 to 1.37; P = 0.320) as well as the other parameters of objective palatine tonsil size, including TH, TW, TT, and TWt, did not differ significantly between overweight children and controls.

CONCLUSION

Obese children with SDB had larger palatine tonsils than did normal-weight children with SDB. This finding suggests that larger palatine tonsils may have a greater effect on upper airway obstruction in obese than in normal-weight children with SDB.
