The Lacrimal Notch Of The Maxilla In Lateral View

Description

Framed in a lateral view of the facial skeleton, the maxilla is presented with attention on the lacrimal notch along its frontal process at the anteromedial margin of the orbit. The curved notch is shown articulating superiorly and posteriorly with the lacrimal bone to complete the fossa for the lacrimal sac, just anterior to the nasolacrimal canal. As the animation progresses, subtle rotation and staged emphasis clarify how this notch sits medial to the orbital rim and superior to the maxillary sinus, bridging the orbital and nasal components of the midface. Small shifts in viewpoint reinforce the notch as a bony boundary rather than an isolated indentation. For oculoplastics and endoscopic lacrimal surgery, this topography is a practical landmark: the lacrimal sac lies immediately adjacent to the lacrimal fossa, and the nasolacrimal duct descends into the inferior meatus where obstruction drives many cases of epiphora and dacryocystitis. Relationship is the lesson. By animating the articulation between maxilla and lacrimal bone and then cueing the downstream path into the nasolacrimal canal, the sequence makes it easier to anticipate where osteotomy is placed during dacryocystorhinostomy and why a misplaced window risks inadequate drainage or injury to nearby orbital soft tissues. Use it in gross anatomy teaching on the orbit and paranasal region, in surgical skills modules introducing external or endonasal DCR, or as a short insert for radiology and ENT resources correlating bony landmarks with the lacrimal drainage pathway on CT. It also fits well in medical publishing when you need a clean orbital medial wall reference without distracting soft-tissue layers. Anatomical accuracy verified by SciePro's Medical Advisory Board.
