Abstract

Key points: • Intraoral, sublabial, and transnasal endoscopic approachs are used to manage odontogenic maxillary cysts. • Transnasal endoscopic approach includes inferior meatal antrostomy, middle meatal antrostomy, and endoscopic medial maxillectomy approach. • Trans-antral endoscopic assisted excision of odontogenic maxillary cyst approach have the advantage of direct lesion access of the sublabial approach as well as the advantages of better illumination, magnification, and small access of endoscopic approach. • The trans-antral endoscopic assisted approach co-morbitity seems to be the least comparing to the benefit of complete excision of the cyst within its entire wall in all the cases with minimal injury of the unaffected maxillary sinus mucosa as well as avoidance of injury of any nearby structure if there is defect in the sinus wall.
