choanal atresia (CA) is a rare occlusion of the posterior choanae. Unilateral cases have been reported more than bilaterally, and it’s more often right-sided in those patients. According to the literature, mixed bony-membranous atresia is the most common type. There is a high incidence of craniofacial and visceral anomalies associated with congenital choanal atresia. Therefore, investigation for associated congenital anomalies is an important step before the surgery. We report 2 cases of incidental finding of unilateral choanal atresia in a 21- and 17-year-old with nasal discharge being the only complaint in the former and nasal obstruction with headache in the latter. The patients were then scheduled for day-surgery as a case of choanal atresia for transnasal, endoscopic repair and posterior septectomy. The patients were discharged home on the same day with the absence of restenosis or other complications.

Background There are congenital and acquired choanal atresias and many approaches have been used for their repair. We assessed the clinical effect of power instrument, endoscopic repair of acquired choanal stenosis and atresia. Methods Nineteen patients, aged from 32 to 61 years, with acquired choanal stenosis and atresia （from trauma in 5 cases and from radiotherapy after nasopharyngeal carcinoma in 14; 6 bilateral and 13 unilateral cases）, underwent transnasal endoscopic repair of choanal stenosis and atresia. No patient had stenting. Antibiotic and local glucocorticoid were administered postoperatively.Results Eighteen patients remained free of symptoms for 12-40 months after the surgery, and the diameter of the neochoana was more than 1 cm after the procedure. One patient required revision surgery and recovered completely with no restenosis at 12 months after the second surgery. There were no postoperative complications. Histology of the resected tissue revealed respiratory epithelial-lined stromal tissue with chronic inflammation, edema and fibrosis, but no tumor cells.Conclusions Transnasal endoscopic approach is a useful procedure for the repair of acquired choanal stenosis and atresia： it is highly successful, safe and effective with swift recovery and short time of hospitalization. It is very important in postoperative care to remove any granulation or polyps at the site of the neochoana at that time.
