Periorbital Region
Pronunciation: peh-ree-OR-bit-ul
The anatomical area surrounding the eye socket, including the upper and lower eyelids and the tear trough, which is a common zone for aesthetic treatment and requires precise anatomical terminology in clinical documentation.
Full Definition
The periorbital region encompasses the tissues surrounding the orbit, including the upper eyelid, lower eyelid, tear trough (infraorbital hollow), lateral canthal area, and brow. In aesthetic dermatology, this zone is treated with fillers, botulinum toxin, laser, and radiofrequency devices. It is anatomically complex due to the proximity of the globe, major vessels, and thin skin, making accurate terminology in clinical notes particularly important. Editors should not conflate 'periorbital' with 'orbital' (which refers to structures within the bony orbit) or with 'periocular', which is used interchangeably in some texts but may carry different connotations in surgical contexts.
Usage
Usage note: Distinguish from 'orbital' (within the bony orbit) and use consistently; 'periocular' is an acceptable synonym but should not be mixed with 'periorbital' within the same document.
In Context
- "Filler placement in the periorbital region carries a higher risk of vascular occlusion than other facial zones." — Clinical guideline
- "The treatment plan documented three units of neuromodulator to the periorbital region for lateral rhytide reduction." — Treatment record
