Choanal atresia is an abnormality of canalization during development of the nasal passages. It involves bone and/or soft tissue and may result in either partial (choanal stenosis) or complete obstruction of the posterior nasal airway. The most widely accepted mechanism for the development of choanal atresia is the persistence of the oronasal membrane beyond the sixth week of gestation, but abnormal migration of cephalic neural crest cells following neural tube closure also has been implicated. The incidence of choanal atresia is 1 in 7000 to 8000 live births. It is more common in females (2:1), more likely to be bony or cartilaginous than membranous (9:1), and more commonly unilateral and right-sided (2:1).

AbstractObjectives:To compare the outcomes of endoscopic repair of bilateral congenital choanal atresia using a flap technique without stenting versus endoscopic repair using stenting without a flap.Methods:A prospective randomised controlled study was conducted, comprising 72 patients with bilateral congenital choanal atresia. The patients were randomised into two groups. Group A (42 patients) underwent endoscopic repair using a mirrored L-shaped flap without stenting, and group B (30 patients) underwent endoscopic repair using stenting without a flap.Results:At a mean follow-up period of 18.2 months, endoscopic assessment revealed a patent posterior choana in 81 per cent and 83.33 per cent of patients in group A and group B respectively. Choanal stenosis occurred in 21.40 per cent and 33.33 per cent of patients in group A and group B respectively. Granulation tissue was observed in 28.6 per cent and 53.3 per cent of patients in group A and group B respectively.Conclusion:The endoscopic approach utilising a flap without stenting is safe and effective, with a high success rate.

AbstractWe report two cases of unilateral choanal atresia and one of choanal stenosis treated successfully by endoscopic fenestration, with no recurrence at a mean follow-up of 18 months. Rigid endoscopy and axial CT scanning confirm the clinical diagnosis and this technique avoids the need for stenting or prolonged postoperative stay.
