Ranula Formation After Lingual Frenectomy in a Newborn

Ankyloglossia is a developmental anomaly characterized by a shortened lingual frenulum, which can range from cases with no clinical relevance to severe cases, where frenectomy may be indicated. In newborns, this indication has increased exponentially. The purpose of this report is to discuss obstruction of the sublingual caruncle, with a recurrent ranula, as a post-surgical complication of laser lingual frenectomy performed in a newborn. The treatment provided is also discussed (marsupialization and removal of the affected sublingual glands). Lingual frenectomy should be performed with great care, especially in newborns, because the sublingual caruncles can be affected and complications can occur.
