Introduction
Odontogenic cyst in the maxilla originates from the epithelial remains associated with odontogenesis1.
It is either developmental, Inflammatory, or Carcinoma arising in odontogenic cysts2. The most common type of odontogenic cysts is periapical (radicular) cysts (65%), followed by dentigerous cysts (24%) and odontogenic keratocysts (5%)3.
Many approaches are used to manage odontogenic maxillary cysts; intraoral, sublabial, or transnasal endoscopic approach. Each approach has its supremacy and pitfalls.
The aim of this study was to present our experience in management of maxillary cysts of dental origin by trans-antral endoscopic assisted approach. We discuss the feasibility, results, benefits, and complications of excision of otontogenic maxillary cyst through a small sublabial incision then a small antral window followed by using 0 degree telescope and endoscopic instruments to completely remove the cyst.
