Endoscopic Transnasal Repair of Bilateral Choanal Atresia in Neonates: Our Experience

Abstract

Introduction:Congenital choanal atresia is the developmental failure of the nasal cavity to communicate with nasopharynx. The newborn baby presents with intermittent attacks of cyanosis and respiratory distress soon after birth. Inability to pass nasal catheters in both the nares reveals the diagnosis of bilateral Choanal Atresia. Study aimed to present our experience with a endoscopic approach for transnasal repair of choanal atresia. Material and Methods:Seven patients with mean age 7 days with bilateral choanal atresia,underwent endoscopic repair using a mucoperichondrial flap from the nasal septum. The bony stenosis was opened with a surgical curette or drill, and the raw surface was covered by the flap. Results:A total of 7 choanae were operated. With mean follow-up 27 months. Out of seven patients operated by us, five patient survived with a patent choana.We had two deaths, one patient expired during the procedure due to bleeding and one patient expired three hour after the procedure due to CCF.Conclusion: Endoscopic repair of choanal atresia is a safe and rapid procedure.

Choanal Atresia: Clinical Features and Factors Affecting Its Surgical Outcomes

“…Milind Navalakhe et al quote this step as one of the fundamental step in their surgery to prevent restenosis. 16 Once the atresia repaired, almost every surgeon is made to face the problems of restenosis. It ranges between 0-85%.…”
