Management and outcome of choanal atresia correction

Management of bilateral choanal atresia in the neonate: an institutional review

“…Only 3 out of 52 patients symptomatically restenosed requiring repeat dilation and re-stenting, all within 12 months. The factors previously reported as prognostic for success in the repair of bilateral choanal atresia include a birth weight heavier than 2.3 kg, greater than 12 weeks of stenting and a large stent (>3.5 mm diameter) [15]. In this series, all patients were stented a median of 12 weeks with a modified endotracheal tube with a diameter of 3.0 or 3.5 mm.…”

An update on choanal atresia surgery at Great Ormond Street Hospital for Children: preliminary results with Mitomycin C and the KTP laser

“…It has been shown that the results after transnasal surgery are comparable to those after transpalatal surgery [1], although the latter is associated with greater blood loss, longer operating time and a more prolonged recovery [2]. For the choice of surgical instruments there are no comparative data, and drills [3][4][5], microdebriders [6][7][8] and lasers [9,10] all have their advocates.…”

Bilateral choanal atresia; evaluation with scintigraphy: Case report

“…The surgical procedures to correct the problem are numerous and include transpalatal, transnasal, transseptal, and sublabial approaches [2,5,9,10]. Technically, the procedures vary from puncture and dilatation to drilling or laser theraphy [5,10].…”

“…Technically, the procedures vary from puncture and dilatation to drilling or laser theraphy [5,10]. Although, there are many methods of correction of CA, a standart management protocol has not been established yet [5]. Early reports state that the transnasal trochar perforation of the posterior choana is associated with severe bleeding and a low rate of success.…”

“…The typical neonatal presentation of bilateral atresia is intermitant cyanosis which improves with crying. The presentation of unilateral atresia is rather late with either persistent nasal discharge or feeding problems [5]. In order to assess the mucociliary clearance and the frequency of ciliary beat, direct methods, such as stroboscopy, photo-electron techniques and indirect methods (vegetable charcoal powder, saccharin, seroalbumine-technetium-99 m Summary Bilateral choanal atresia is a rare congenital anomaly that may cause severe neonatal respiratory distress.…”
