Nasal obstruction (NO) is defined as a single or bilateral nasal breathing disorder, recent or old, permanent or intermittent. It is a frequent problem in pediatrics and underestimated because of the absence of complaint in young children or unknown when the complaint is unilateral [1]. Although the majority of causes of ON belong to the infectious pathology, one must know to think of a syndrome malformative or tumoral [2]. The ON can cause significant troubles both locally and generally [1]. It is necessary to objectify the cause quickly especially in the newborn because of the vital consequences that this obstruction can cause [1].
