Two routes of approach, the transnasal and the transpalatine, are used with equal frequency to treat choanal imperforations in infants, the transpalatine approach being traditionally reserved for children over 1 year of age. A retrospective study of 30 children treated between 1974 and 1981 demonstrated that results were insufficient when the transnasal approach was used (80 p. cent failures) when compared with those obtained with the transpalatine approach (90 p. cent successful). A suggested explanation for the superiority of the transpalatine approach is advanced, and this approach route proposed for initial surgery during the neonatal period based on the results of recent experimental studies showing its safety with regard to maxillary growth.
