An oronasal fistula (ONF) is an abnormal communication between the oral cavity and the nose that can be caused by traumatic, post-operative, oncological sequelae and congenital malformations. ONF are usually complicated to treat for multiple local anatomical reasons. Among the various closure options is the pedicled lingual flap (PLF), which can be used to close defects larger than 2 cm, but requires certain additional care during the post operative recovery. Objective: To show, through the report of 3 cases and a review of the literature, the benefits and disadvantages of the PLF surgical technique in cases with oronasal defects greater than 2cm. Case report: 3 male patients, between 17-24 years old, were included. As a consequence of a previous unsuccessful procedure, all of them had anterior palatine fistulas greater than 2 cm, two due to palatoplasty and one as a consequence of a gun...

Oral verruciform xanthoma is a benign inflammatory lesion of unknown etiology. It is a reactive, non-tumorous lesion affecting the oral mucosa, the semi-mucosa, and the skin of the extremities. Its clinical presentation consists of a single, elevated lesion with an irregular surface. Its microscopic characteristic is the accumulation of lipid-containing macrophages in the papillae of the connective tissue between the epithelial ridges. This report reviews the literature and presents a case of this pathology. The patient is an 11-year-old female who came for consultation with her guardian. Clinically, a single pale pink lesion approximately 4 mm in length, oval in shape with defined borders, rough, keratinized surface, firm consistency, and a base adhered to the tissue was observed. An excisional biopsy and histopathological study were performed. In conclusion, the diagnosis of verrucifor...
