Please specify

Surgical intervention

ii Description/ name of Intervention/article

Adenotonsillectomy (AT) will be offered as a treatment of OSA for this group of subjects. Turbinate reduction procedure will also be performed if the subject has current history of allergic rhinitis and examination reveals at least grade II turbinate hypertrophy. (Grade I is no turbinate hypertrophy; Grade II is turbinate hypertrophy without touching the septum; Grade III is turbinate hypertrophy and it touches the septum). The procedure will be performed by an experienced ENT surgeon within 4-6 weeks post randomization. Subjects allocated to this group will be reassessed 6 months after surgery.

16Comparative Treatments

i Description/ name of comparative treatments

Watchful waiting group
Children allocated to this group will not receive any form of intervention. This is similar to our current practice where children diagnosed with OSA and planned for surgery will have to wait for between 5-6 months before the procedure. At the end of the study, early intervention will be offered for children whose OSA remains as moderate-to-severe. Subjects allocated to this group will be reassessed 7 months after the baseline visit.
