Summary: | Objectives: This study aimed to evaluate cognitive and behavioural changes among 9–14-yearold
Omani children with obstructive sleep apnoea (OSA) after an adenotonsillectomy (AT). Methods: This
naturalistic observational study was conducted at the Sultan Qaboos University Hospital, Muscat, Oman, between
January 2012 and December 2014. Omani children with adenotonsillar hypertrophy (ATH) underwent overnight
polysomnography and those with confirmed OSA were scheduled for an AT. Cognitive and behavioural evaluations
were performed using standardised instruments at baseline prior to the procedure and three months afterwards.
Results: A total of 37 children were included in the study, of which 24 (65%) were male and 13 (35%) were female.
The mean age of the males was 11.4 ± 1.9 years, while that of the females was 11.1 ± 1.5 years. Following the
AT, there was a significant reduction of 56% in mean apnoea-hypopnoea index (AHI) score (2.36 ± 4.88 versus
5.37 ± 7.17; P <0.01). There was also a significant positive reduction in OSA indices, including oxygen desaturation
index (78%), number of desaturations (68%) and number of obstructive apnoea incidents (74%; P <0.01 each).
Significant improvements were noted in neurocognitive function, including attention/concentration (42%),
verbal fluency (92%), learning/recall (38%), executive function (52%) and general intellectual ability (33%; P <0.01
each). There was a significant decrease of 21% in both mean inattention and hyperactivity scores (P <0.01 each).
Conclusion: These results demonstrate the effectiveness of an AT in improving cognitive function and attention
deficit hyperactivity disorder-like symptoms among children with ATH-caused OSA. Such changes can be observed
as early as three months after the procedure. |
