What is lamina papyrcea?

Lamina papyracea is a thin bony wall that separates the ethmoid sinuses from the orbit, which is the bony cavity that encloses and protects the eye. It is a part of the ethmoid bone, a complex bone structure located between the eyes that also forms parts of the nasal cavity and the base of the skull. The lamina papyracea is a fragile and delicate structure that is susceptible to fractures, which can occur due to trauma or underlying medical conditions such as sinusitis or osteoporosis. A fracture of the lamina papyracea can lead to orbital penetration, which can cause damage to the eye or other vital structures in the region. Therefore, it is important for medical professionals to be aware of this potential complication when planning surgeries or interventions involving the nasal or orbital area.
