Abstract
Chronic maxillary atelectasis (CMA) is a rare and developed condition that consists in the progressive and persistent decrease volume of the maxillary sinus, with centri- petal retraction of the walls secondary to the complete occlusion of the natural ostium. This condition generates negative pressure inside the maxillary sinus, heading to atelec- tasis and collapse of the walls. It is proposed that the disease includes the silent sinus syndrome, as the physiopathology is shared between them. We present the case of a 3 years old boy with bilateral chronic maxillary atelectasis observed in the CT scan, who evolved with spontaneous bilateral resolution. The right maxillary sinus CMA resolved at 6 years old, and the left at 10 years old.
