Dec 18, 2020 · This chapter provides a description of the superficial anatomy, the osteology, and the musculature of the orbit and periorbital region, and drainage of lacrimal fluid. The vasculature of the orbit is outlined highlighting the extensive vessel anastomoses in the...

This article provides a detailed illustration and description of the microsurgical anatomy of the orbit, with a focus on the intrinsically complex spatial relationships around the annular tendon and the superior orbital fissure, the transition from cavernous sinus to the orbital apex.

May 26, 2017 · Anatomy of the most well-developed supporting system of the medial rectus muscle that reaches the inferior wall, the inferior rectus muscle, and the superior muscle complex.

May 18, 2020 · Movement of the brow is produced through the action of brow elevators and depressors and is enhanced by the presence of the galeal fat pad, glide plane space and subgaleal space. The periosteum of the frontal bones is reflected at the arcus marginalis to become the periorbita of the periorbital bones.

Nov 12, 2020 · The periorbita, also called the orbital periosteum or orbital fascia, covers the bones of the orbit. This dense connective tissue membrane serves as an attachment site for muscles, tendons, and ligaments and is a support structure for the blood supply to …

Jul 16, 2017 · Orbital and palpebral parts of orbicularis oculi muscle. Palpebral part is subdivided into preseptal and pretarsal parts. The OOM is greatly involved in the blepharoplasty procedures.

The periorbita (orbital periosteum; orbital fascia) is a dense connective tissue membrane that covers the bones of the orbit. It serves as an attachment site for muscles, tendons, and ligaments and is a support structure for the blood supply to the orbital bones.

Following are the main structures that make up the anatomy of the orbitopalpebral region: The main function of the orbit is to give support and protection to the eyeball and its structures. The volume of the orbital cavity of an adult is approxi-mately 30cc.
