Introduction: Obstructive Sleep Apnoea (OSA) is characterised by repeated instances of the upper airway partially or completely collapsing during sleep, leading to a decrease in airflow (hypopnoea) or a complete absence of airflow (apnoea) that lasts for at least 10 seconds. Craniofacial structure and hyoid bone position significantly influence airway patency. Cephalometric evaluation of these parameters in children with and without OSA can help identify early morphological indicators of airway
