Background and Objectives:Hypertrophy of adenoids was recognized as one of the main causes of snoring and obstructive sleep apnea (OSA) in pediatric patients. Recently, two endoscopic adenoid grading system was pro- posed, Parikh grade (P-G) and ACE grade (ACE-G). The aim of this study is to evaluate the correlation between obstructive sleep apnea severity and these two endoscopic adenoid grading systems.
Materials and Methods: We retrospectively reviewed the medical records of 52 patients who underwent a polysomnography and endo- scopic nasal endoscopy in the secondary referral hospital from 2008 to 2017. Adenoid exam was performed with nasal endoscopy after nasal packing soaked with lidocaine and xylometazoline in out-patient clinic. It was evalu- ated the correlation between each adenoid grading system and apnea-hypopnea index, adjusted by sex, age, tonsil grade, body mass index, and presence of allergic rhinitis.
Results:Mean age was 7.6 year (range : 2-15, SD : 2.57) and 75% of the patient had obstructive sleep apnea (AHI≥1). P-G was statistically correlated with OSA se- verity. (OR=11.8, 95% CI : 1.5-92.2, p=0.02) Only subgrade E of ACE-G has meaningful correlation with OSA severity (OR=2.07, 95% CI : 0.91-4.81 p=0.03).
Conclusion:P-G and subgrade E of ACE-G were statistically related to sleep apnea severity in pediatric patients. Endoscopic adenoid grading system can be useful tool to eval- uate adenoid hypertrophy and upper airway in pediatric OSA patients.
