title: A new dynamic endonasal stent for bilateral congenital choanal atresia.
abstract: The Authors describe a new dynamic endonasal Teflon stent, nick-named "little gun", used after the surgical transnasal endoscopic treatment of bilateral choanal atresia in a 4-day-old male. This Teflon stent, conceived to perfectly fit the new naso-choanal openings and to achieve an "orthopaedic" tutorial function, is made of three portions: "A", the barrel, "B", the breech, "C" the butt. The butt is the active part of the splint and must be rolled up around itself, in order to create a spiral tube, fitting to the new choanal openings, able to expand laterally on account of its intrinsic elastic resilience.
