RESUMO
OBJECTIVE: To evaluate the correlation between obstructive sleep apnea syndrome (OSAS) and the development of thoracic deformity in Children. METHODS: A retrospective analysis was performed with the medical records of 39 pediatric OSAS patients with thoracic deformity and matching 39 without thoracic deformity as control group between January 2015 and June 2019. The contrast was performed with age, gender, height, weight, body mass index (BMI), apnea/hypopnea index (AHI), the lowest oxyhemoglobin saturation (loSpO2)at night, tonsil and adenoid size, Alkaline phosphatase (ALP)and trace elements and metals between two groups. RESULTS: BMI, AHI, the lowest SpO2, Phosphorus and Zinc were the risk factors of thoracic deformity. Age, gender, disease history, the size of tonsil and adenoid, ALP and other trace elements were no significant difference occurred between two groups. CONCLUSION: OSAS characterized by apnea and hypoxia which are caused by narrow upper airway may be one cause of thoracic deformity in children. Pediatricians, thoracic and otolaryngologic surgeons should be alert to OSAS when thoracic deformities are diagnosed in children.
