The effect of aryepiglottoplasty for laryngomalacia on gastro-oesophageal reflux

Abstract 

Objective: to investigate whether relief of airway obstruction in laryngomalacia by aryepiglottoplasty affects gastro-oesophageal reflux. Methods: a prospective study of consecutive infants and children with suspected laryngomalacia. Gastro-oesophageal reflux was measured before and after diagnostic microlaryngobronchoscopy and aryepiglottoplasty. Results: of the six cases who underwent aryepiglottoplasty and completed the study, three had significant pre-operative reflux according to age. In this group the reflux improved significantly after aryepiglottoplasty. In the other three cases, reflux was not age-significant pre-operatively nor did it change significantly post-operatively. Conclusions: when partial airway obstruction due to laryngomalacia co-exists with gastro-oesophageal reflux, treatment of the airway problem improves respiratory symptoms in all cases and reduces gastro-oesophageal reflux in patients with age-significant reflux. This suggests that there are two clinical groups, those with severe, age-significant reflux, possibly caused by airway obstruction, whose gastro-oesophageal reflux benefits from aryepiglottoplasty; and those whose reflux is physiological and not influenced by aryepiglottoplasty. Therefore aryepiglottoplasty can be expected to reduce gastro-oesophageal reflux in those infants with laryngomalacia who have age-significant reflux.
