choanal atresia was first described by roeder in 1755.1 choanal atresia is the narrowing or obstruction of the posterior nasal fossa. this anomaly could be congenital or acquired. most patients are female.2 choanal atresia might be isolated or associated with other anomalies like charge syndrome and 20-50% of congenital cases have this company.3 choanal atresia could be unilateral or bilateral ...

INTRODUCTION Congenital choanal atresia is a relatively rare deformity, especially bilateral congenital choanal atresia. We report a case of bilateral congenital choanal atresia in a 22-year-old Chinese man, who was also diagnosed with congenital right accessory nasal deformity, osteoma of his left ethmoid sinus and congenital keratoleukoma of his right eye. CASE PRESENTATION A 22-year-old Ch...

Congenital choanal atresia has been recognized for over 200 years, first described by Roederer in 1775 (Lantz and Brick, Laryngoscope 91, 1981, 1626. Samuel and Fernandes. Laryngoscope 95, 1985, 326). This condition is unconunon, occurring in approximately 1 in 7000 live births. Unfortunately, a single ideal procedure for this condition does not exist. Stankiewicz is credited with the first des...

Congenital posterior choanal atresia is an uncommon anomaly which may have lifethreatening consequences. This defect is frequently associated with other congenital abnormalities. CT scan confirms the diagnosis and accurately defines the anatomy of the atresia and differentiates osseous stenosis from membranous stenosis in the choanae. Therefore, CT may be the first-line imaging choice for the p...

Bilateral choanal atresia is a congenital anomaly which occurs immediately after birth and requires immediate intervention. Therefore, it is very rare to see a patient who has reached an advanced age. In this article, we report two cases (sisters) who were able to reach advanced ages with bilateral choanal atresia. In the light of these two adult cases, we aimed to review the diagnostic and the...

Choanal atresia is a well-defined congenital malformation; however, little is known about its prevalence and risk factors. Data from the Iowa Registry for Congenital and Inherited Disorders were used to examine prevalence, infant, and maternal characteristics of choanal artesia. Data from the National Birth Defects Prevention Study (NBDPS) were used to examine selected risk factors for choanal ...

INTRODUCTION Choanal atresia is a rare congenital malformation of the nasal cavity characterized by the complete obliteration of the posterior choanae. In 67% of cases choanal atresia is unilateral, affecting mainly (71%) the right nasal cavity. In contrast to the unilateral form, bilateral choanal atresia is a life-threatening condition often associated with respiratory distress with feeding a...
