Trans-nasal endoscopic repair without stenting in bilateral congenital bony choanal atresia: Our technique
Background
Infants with bilateral Choanal Atresia (CA) can present as an airway emergency at birth. The goal of initial treatment is to maintain an adequate airway.[1] Incidence of choanal atresia is around 1 in 7,000 live births[2] It is a potential life threatening condition in neonates because this condition is predominantly in first 6 weeks of births[3]. 65–75 % of patients with choanal atresia are unilateral, and the rest are bilateral[4] There are five different approaches described for surgical treatment of CA: (1) trans-nasal, (2) trans-palatal, (3) trans-antral, (4) trans-septal and (5) sublabial– transnasal.[5], [6] Our objective is to report our experience in Trans-nasal Endoscopic Minimal Invasive Technique without stenting for the surgical management of CA.
Technique
1. This case series includes 6 children who presented or referred to our Hospital with congenital bilateral CA between October 2015 to July 2017. Institutional Review Board approval was taken. We used a Trans-nasal Endoscopic Minimal Invasive Technique without stent placement. It is based on the following steps
2. Stents and nasal packs were not placed in any case. No topical mitomycin or corticosteroids were applied. Postop care: Antibiotic Therapy, Nasal Saline Spray at least twice a day for several weeks were recommended. Patients underwent a regular follow-up to wash away crusts and secretions and verify choanal patency. All patients were followed up at-least for 18 months.
Discussion
Four patients were male and two were female. Only 1/6 patient needed revision surgery for restenosis. Mean Procedure time = 90 min (range = 60-120 min) Mean Hospital stay = 4.3days (range = 3 to 9 days) No intra- and/or early postoperative complications such as epistaxis, infection noticed.
Erosion of the nares or intranasal synechiae occurred. All patients underwent postoperative follow-up with clinical evaluation. One patient developed naso palatine fistula due to drilling choanal part as this patient was having high arched palate. No significant regurgitation noticed through the fistula.

Conclusion
Repair without stenting avoids the potential for stent-related complications, such as discomfort, localized infection and ulceration, circumferential scar or granulation tissue formation. A combination of close post-operative follow-up, revision endoscopy to remove nasal crusting 1 week after the primary repair, and frequent nasal saline irrigation was the key to successful management of CA without stenting. However, due to the number of patients included, these findings cannot be generalized and a larger sample is necessary to obtain statistically significant conclusions.
Clinical significance
We suggest this Trans-nasal Endoscopic Surgery because it follows the basic requirements of a minimally-invasive corrective approach: the creation of patent posterior nasal choana sufficient for nasal breathing, minimization of endonasal scar tissue formation, absence of secretion accumulation, and prevention of abnormal craniofacial growth in children who have not reached their full growth yet.
