Antrochoanal polyp presenting as obstructive sleep apnea.

Antrochoanal polyps (ACPS) are uncommon in children presenting to the pediatric clinic. They commonly present with unilateral nasal obstruction. ACPS presenting as obstructive sleep apnea (OSA) in a young child is an uncommon initial presentation. A high level of suspicion is needed to diagnose OSA in young children as the presenting symptoms may be nonspecific and sometimes misleading.
