Study Notes
- Selçuk Sürücü discussed the anatomy of the eye socket and structures within it
- Roof of eye socket is also floor of maxillary sinus and parts of frontal sinus
- Infraorbital sulcus passes through the maxilla and exits as infraorbital foramen
- The infraorbital foramen is the passage for a branch of the maxillary nerve
- Blow out fractures can occur in the thin, fragile medial bony wall of the orbit due to trauma
- Structures in the orbit include the eyeball, adipose tissue (orbital fat body), neurovasculature, accessory eye structures, and eyelids
- Eyelids provide protection, lubrication, and maintain vision through blinking
- Eyelids consist of the palpebral, lacrimal, and orbital parts of the orbicularis oculi muscle
- The orbicularis oculi muscle attaches to the medial orbital margin, medial palpebral ligament, and lacrimal bone
- Eyelids are innervated by the facial nerve (CN VII) and have tarsal plates and Meibomian glands.
