Apparatus for use in the treatment of choanal atresia and in the prevention of stenosis following choanal atresia repair in infants comprises two choanal tubes adapted to lie side-by-side each of a plastics material approved for use in humans and each having a lengthwise extending flexible metallic insert embedded internally within its wall(s). The ends of a strip of plastics material are attached one to one end of each of the choanal tubes and a bridge of plastics material extends between and is removably attached to the choanal tubes at or towards their ends remote from the strip of plastics material. The arrangement is such that, in use, the choanal tubes are positioned in the nasal passageways and transnasal openings of an infant with the plastics strip extending behind the cartilage which separates the nasal passageways, and with the bridge positioned adjacent the columella of the infant.
