Removal of an Intraosseous Venous Malformation of the Maxilla via a Transoral-transconjunctival-Transcaruncular Approach.

Intraosseous vascular anomalies represent less than 1% of all bony tumors. When they involve the maxillofacial skeleton, these masses may cause substantial morbidity and aesthetic concern. Herein, we highlight a case of a maxillary intraosseous venous malformation manifesting as functional lacrimal duct obstruction with epiphora, sinus pressure, and increasing medial canthal/maxillary fullness over 2 years in a young, healthy woman. Surgical excision of the lesion was accomplished without a skin incision by coupling a transoral, midface degloving technique with a transconjunctival-transcaruncular approach. This minimally invasive technique led to complete resolution of symptoms and a satisfactory cosmetic outcome, without a cutaneous scar.
