We report the case of a 15-year-old boy with obstructive sleep
apnea and obesity who was treated since the age of 5 with nasal
continuous positive airway pressure. Due to the long-term use of a
nasal mask, the child developed a mid-face hypoplasia. Chronic use of a
nasal mask for home ventilation in children should always be associated
with regular evaluations of maxillomandibular growth.
