Congenital mucoceles: report of two cases

Congenital mucoceles are very rare. Only two previous cases presenting in the neonatal period have been reported. Two cases are presented here, one arising within the tongue and the other in the floor of the mouth. In both cases the mucoceles became apparent soon after birth because they interfered with mouth closure and normal feeding. The cysts were surgically excised and histopathological examination showed that they were retention cysts. The infants quickly resumed normal oral function and swallowing after surgical removal.
