Abstract Choanal atresia CA is a relatively uncommon but well-recognized condition characterized by the anatomical closure of the posterior choanae in the nasal cavity. Since the original description back in the early eighteenth century, there have been controversies regarding its exact pathogenesis, the optimal surgical approach, and the use of adjunct treatments such as post-surgical stenting and anti-neoplastic agents, despite of abundant literature available. The emergence and development of new technologies play a significant role in the management of this condition. This review provides a comprehensive clinical update on CA and identifies areas for future study based on the existing available literature. Keywords: choanal atresia, human, diagnosis, children, management Introduction Choanal atresia CA is a well-recognized etiology for congenital nasal airway abnormality that could have various clinical presentations ranging from acute airway obstruction to chronic recurrent sinusitis. This disease entity was first described by Roederer in 1 while Oto et al. Emmert et al. By s, most of CA clinical features were recognized, and four surgical techniques including trans-nasal, trans-septal, trans-palatal, and trans-maxillary approach had been devised 4. Since the first description back in eighteenth Century, there has been abundance of literature describing various aspects of CA. However, there are still controversies on the exact pathogenesis, the effectiveness on various surgical techniques, and the use of post-surgical stenting and anti-neoplastic agent as adjunct for the surgical treatments. The purpose of this review is to provide a comprehensive clinical update on CA and to identify areas for future study based on the existing literature available currently.

Relevant Anatomy and Epidemiology Choanal atresia, defined as the anatomical closure of the posterior choanae in the nasal cavity, is relatively uncommon disease entity with an estimated incidence of — birth 5.

Anatomic boundaries of the posterior choanae include the undersurface of the body of the sphenoid bones superiorly, the medial pterygoid lamina laterally, the vomer medially, and the horizontal portion of the palatal bone inferiorly.

The actual narrowing could be caused by one of the abovementioned bony components. Correctly identifying and addressing the point of obstruction is the key to surgical success.

Embryology and Pathogenesis Development of the nasal cavity starts with neural crest cells migration from their origin in the dorsal neural folds at about 3. During the subsequent 2 weeks, nasal processes or placodes invaginate to form the nasal pits.

The nasal pits burrow deeper within the mesenchyme while nasobuccal membrane normally will rupture to create a nasal cavity with the primitive choana Four basic theories have been accepted over the years 8 : 1 Persistence of the buccopharyngeal membrane from the foregut.

Various molecular or genetic models have been studied to give further insights in the pathogenesis of CA. The role of retinoic acid Retinoic acid deficiency during gestation period has been known to induce numerous malformations Retinoic acid RA produced from vitamin A by retinaldehyde dehydrogenase Raldh is important for ontogenesis and homeostasis of numerous tissues Using a mouse model, Dupe et al.
