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.
