Bilateral Choanal Atresia in a 42-year-old Patient: A Rare Condition Case Report

Choanal atresia is an uncommon condition with an incidence of 1:5,000-8,000 live births, affecting females more frequently and often associated with other malformations. This case report presents a 42-year-old female patient who was born with bilateral choanal atresia and intervened surgically for the first time at birth. However, the formed orifice was reobstructed a few months afterward, necessitating reoperation in adulthood. The purpose of this case report is to describe bilateral choanal atresia in detail, including its clinical presentation, epidemiology, diagnosis, pathogenesis, and therapeutic approach. It aims to enhance understanding of this rare but significant condition.
