Comparisons of thyroid hormone, intelligence, attention, and quality of life in children with obstructive sleep apnea hypopnea syndrome before and after endoscopic adenoidectomy.

Objective. The aim of this study was to compare the differences in thyroid hormone, intelligence, attention, and quality of life (QoL) of children with obstructive sleep apnea hypopnea syndrome (OSAHS) before and after endoscopic adenoidectomy. Method. A total of 35 OSAHS children (21 males and 14 females with a mean age of 6.81 ± 1.08 years) were included in this study for analyzing the levels of thyroid hormone, intelligence, attention, and QoL. There were 22 children underwent endoscopic adenoidectomy with bilateral tonsillectomy (BT), while the other 13 children who underwent endoscopic adenoidectomy without bilateral tonsillectomy without BT. Results. Our results revealed no significant difference in serum free triiodothyronine (FT3), free thyroxine (FT4), and thyroid stimulating hormone (TSH) levels in OSAHS children before and after endoscopic adenoidectomy (all P > 0.05). However, there were significant differences in full-scale intelligence quotient (FIQ) (92.45 ± 5.88 versus 106.23 ± 7.39, P < 0.001), verbal intelligence quotient (VIQ) (94.17 ± 15.01 versus 103.91 ± 9.74, P = 0.006), and performance intelligence quotient (PIQ) (94.12 ± 11.04 versus 104.31 ± 10.05, P = 0.001), attention (98.48 ± 8.74 versus 106.87 ± 8.58, P < 0.001), and total OSA-18 scores (87.62 ± 17.15 versus 46.61 ± 10.15, P < 0.001) between before and after endoscopic adenoidectomy in OSAHS children. Conclusion. Our findings provided evidence that the intelligence, attention, and QoL of OSAHS children may be significantly improved after endoscopic adenoidectomy.
