Layer: Bones

Educational content only — not medical advice.

Anatomy

The smallest facial bone, hidden in the medial wall of the right orbit behind the nasal bone; it helps form the lacrimal fossa where the lacrimal sac sits before draining into the nasolacrimal duct.

Clinical notes

Obstruction of the tear duct beneath this bone causes constant watering (epiphora) needing dilation or dacryocystorhinostomy (DCR); the thin orbital lamina must be respected during surgery.
