Dj. Beste et al., GASTROESOPHAGEAL REFLUX COMPLICATING CHOANAL ATRESIA REPAIR, International journal of pediatric otorhinolaryngology, 29(1), 1994, pp. 51-58
Four infants with bilateral congenital choanal atresia (CCA) underwent
transpalatal (3) or transnasal (1) repairs. Postoperatively all four
infants experienced gastroesophageal reflux (GER) with intermittent na
sal reflux. GER was documented by GER radionuclide scanning in one pat
ient and by dual nasopharyngeal and esophageal pH probe studies in the
remaining three patients. The infants with documented GER required pr
olonged stenting and dilations for choanal restenosis and granulations
. The literature emphasizes the importance of the technical repair for
prevention of these complications; GER can be a significant complicat
ing factor.
