Endoscopic transnasal repair of choanal atresia: clinical characteristics and outcomes from a main tertiary hospital in Syria

Endoscopic transnasal repair of CA was shown to be safe and effective in a resource-limited setting, with recurrence and complication rates comparable to international reports. Routine use of stents, steroids, mitomycin C, or laser showed no clear benefit, supporting selective rather than standard application. These findings contribute regional data to the global literature and underscore the need for larger multicenter studies to refine prognostic factors and optimize long-term outcomes.
