Significance of Posterior Septectomy in the Management of Choanal Atresia in Young Adults

Unilateral choanal atresia is more common than bilateral cases. Unilateral cases may present later in life with unilateral nasal congestion and mucoid rhinorrhea. Pure bony atresia represents 30% of cases while mixed bony and membranous atresia is more common (70%) [1]. The ideal procedure for management of choanal atresia should restore the normal nasal passage, be safe, prevent damage to any growing structures, have short operative time, short hospitalization and convalescence with minimal morbidity and mortality. Endoscopic transnasal management is a challenging procedure and is considered the standard route in choanal atresia surgery [2]. The aim of this study is to present our experience with a transnasal endoscopic posterior septectomy without postoperative stenting for repair of choanal atresia in relatively young adult patients.
