선천성 후비공폐쇄증 = A Case of Congenital Choanal Atresia

다국어 초록 (Multilingual Abstract)

Choanal atresia was first described in 1775 by Johann Roederer; it consists of abnormal membrane or bony closure of one or both posterior choanae.
The most likely explanation of the congenital abnormality is the persistence of the nasobuccal or buccopharyngeal membrane.
In the newborn, since they are obligate nose breathers, this condition is of utmost urgency and quick provision of a nasal airway may be lifesaving.
The early surgery for choanal atresia was transnsal, but the difficulties in visualization adn the high incidence of restenosis prompted to develop the transpalatine route.
The authors experienced one case of congenital choanal atresia in 10-year-old female child who was admitted due to purulent nasal discharge, sneezing and coughing. She was operated though transpalatine approach and was discharged with good condition on 11th hospital day.
