Abstract

Objectives:

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.
