Maxillary vestibular approach
In the surgical treatment of facial trauma, the skeleton of the lower midface is commonly exposed using a transoral approach in the maxillary vestibule.
A horizontal incision (possibly with hockey stick endings) through the maxillary vestibular mucoperiosteum is made slightly above the mucogingival junction. The subsequent subperiosteal dissection can be advanced to access the entire anterolateral bony surfaces from the zygomaticotemporal suture over the facial antral wall to the borders of the piriform aperture and up to the infraorbital rim including the infraorbital nerve exit.
