CRE-2013.599

Childhood obstructive sleep apnoea

Procedure

Adenotonsillectomy +/- Turbinate reduction

N/A

N/A

Subjects will be reassessed 6 months after the date of surgery

N/A

Watchful waiting:
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.

(i) Hong Kong Chinese pre-pubertal children aged between 5-11 years.
(ii) Moderate-to-severe OSA confirmed by PSG (AHI >3/h).
(iii) Tonsil size grading ≥1 and considered to be candidates for surgical intervention by ENT surgeon.
(iv) Written informed consent obtained from parents.

(i) Obesity, defined as having a body mass index (BMI) ≥95th percentile (corresponding to a z score of 1.645) of the local reference.
(ii) Previous upper airway surgery or currently receiving treatment for OSA.
(iii) Known medical conditions that could affect airway and BP control, for example cranio-facial, neuromuscular diseases and congenital heart disease.
(iv) Receiving medications that could alter BP control.
(v) Severe health problems that could be exacerbated by delayed treatment of OSA, for example chronic lung disease.
