Abstract: Congenital choanal atresia(CCA)refers to the anatomical closure of the posterior nostril, which is clinically characterized by no nasal respiratory airflow. The typical manifestations of CT are thickening of the bone of the posterior vomer, pterygoid plate, and closure of the choana with bony/and or membranous plate. According to the extent of the lesion, it can be divided into bilateral atresia and unilateral atresia, and the former often needs timely treatment. Transnasal endoscopic surgery is the first choice of surgery, and its safety and effectiveness have been certified in the past decade. However, postoperative stenosis is still the most important complication. It has been controversial whether the application of traditional stent and mitomycin C is beneficial to avoid postoperative stenosis. At present, some new methods to prevent postoperative stenosis(steroid-eluting stent, and balloon dilatation, and local application of the carboxymethyl cellulose gel-sodium salt)are still emerging, Which may offer promising prospects for the treatment of choanal atresia.

Key words: Choanal atresia, Endoscope, Diagnosis, Treatment
