Choanal Atresia Repair, A Comparison Between Transnasal Puncture With Dilatation And Stentless Endoscopic Transnasal Drilling

 

Abstract

Background: in this study we present the outcome of surgical repair of choanal atresia of 33 patients underwent the surgery at Tripoli University hospital and Tripoli central hospital
Objectives: The aim of this study to compare between two procedures used to repair choanal atresia. The first procedure is perforation and dilatation with stenting and the second procedure is endoscopic drilling without stenting. The comparison looked at the main complication which is restenosis of the choana.
Method: A review the medical notes of 33patients diagnosed with choanal atresia and subjected to surgical repair. Results: 8 patients out of 13 developed restenosis after treatment with perforation and dilatation (61.5%), While 4 patients out of 20 treated with trans-nasal endoscopic drilling without stenting (20 %)
Conclusion: The study showed that the risk of restenosis is significantly less in trans-nasal endoscopic drilling technique and the result of this procedure is comparable to the published data
