title: [Endoscopic transnasal repair of congenital choanal atresia].
abstract: Two cases of congenital choanal atresia treated with endoscopic transnasal repairing were reported. Nasal endoscopy and axial CT scanning are important for establishing the diagnosis. Endoscopic plastic operation for choanal atresia is the best procedure. There are following advantages: short approach, clear field of vision, complete resection of atresia plate, well preservation of mucosa on the nasopharyngeal side of atresia plate, no side injury, less bleeding and higher success. The mucosa preserved completely on the nasopharyngeal side can totally cover the bare bony edges. The endoscopy after operation is important to remain nasal patency.
