Cirugía endoscópica en un niño con atresia unilateral de coana

Abstract

Introduction and objective: Choanal atresia is rare, being twice as common in women than in men, and in 50% of cases approximately it is associated with other congenital anomalies. Although there has been some controvesia about the treatment of choice of this malformation, in the last decade, the introduction of endoscopes in sinus surgery has improved the outcome. Case description: We report the case of a child who has left chronic rhinorrhea with persistent nasal obstruction. By endoscopy and CT diagnosis, left choanal atresia is confirmed. Unilateral choanal atresia endoscopic surgery is performed by creating flaps with intranasal mucosa, preventing nasal packing. Discussion: Different techniques have been considered for the treatment of choanal atresia, which include traditional and endoscopic approach. The results of endoscopic surgery in the choanal atresia vary according to different authors. The two most important aspects of these results are the creation of nasal mucosa flaps and avoiding nasal packing. Conclusions: Surgical treatment of unilateral choanal atresia by endoscopic surgery can reduce the risk of restenosis.
