  2. 2. Contents: Treating the periorbital region Introduction Anatomy of the periorbital region Effects of ageing on the periorbital region Treatment overview Potential complications Injection techniques
  3. 3. The periorbital features are the most scrutinised of the face1 • The upper face is:1,2 - The aesthetic centre of the face - Where we look to estimate age - The region we use to judge a person’s emotional state • The periorbital region is one of the first to show the effects of ageing3 1.

  5. 5. The skin around the orbita is the thinnest of the face1 • In general, facial skin is thinner in the upper face compared with the lower face region2 • During ageing, skin thickness increases on the forehead and cheeks but decreases in infraorbital areas2 1.

  18. 18. The facial muscles are concealed by subcutaneous fullness in youth1 1. Coleman SR et al. Aesthet Surg J 2006;26(1S):S4–9. During ageing, significant loss of subcutaneous volume accentuates the underlying bone and muscle structures1
  19. 19. Eyebrow fat volume increases with age1 • Major component of eyebrow volume is soft tissue/muscle1 • Only 18% of eyebrow volume consists of fat1 • Decrease in soft tissue/muscle volume1 • Significant increase in galeal fat pad1 • 81% of eyebrow volume consists of fat1 21-year-old female* 76-year-old female* * 3D reconstruction analysis using CT scan of the face Image reproduced with permission: Papageorgiou KI et al.

  20. 20. Volume loss is the predominant cause of tear trough deformity1 • Tear trough deformity is a hollow ridge below the eye, which results in a fatigued appearance1 • The underlying cause of tear troughs can be multifactoral, including:1 – Volume loss – Skin laxity 1. Sadick N et al. J Cosmet Dermatol 2007;6(4):218–22. In some patients, dark circles under the eyes can also develop due to prominent subcutaneous venous pooling, pigmentation and changes in skin thickness1

Editor's Notes

  • This slide highlights the blood vessels of importance in the periorbital region.
  • This slide shows how the periorbital area can change with age.

    In youth, the muscles of facial expression are concealed by subcutaneous fullness. However, during ageing significant loss of subcutaneous fat from facial fat pads in the forehead, brow, temple and upper eyelids occurs
    This volume loss accentuates the underlying bone and muscle structures and leads to drooping of the skin. Loss of facial volume in the midface region has a particularly significant impact on the tear trough region

    Reference
    Coleman SR et al. Aesthet Surg J 2006;26(1S):S4–9.
  • There is no change in total eyebrow volume with age. However, there is a decrease in soft tissue/muscle volume alongside an increase in fat volume
    The distribution of fat alters with age due to increased resting tone and repeated contractions of the mimetic muscles

    Reference
    Papageorgiou KI et al. Aesthet Sur J 2012;32(1):46–57.
  • The causes of tear trough deformity are multi-factorial but volume loss is the predominant issue
    Loss of fat from the cheek can also generate a downwards displacement or sagging of the lower portion of the face (herniation of the cheek fat pad), which worsens the tear trough deformity
    Tear trough deformity can produce shadowing and gives the impression of being tired

  • Therapeutic indications of VISTABEL®1

    When the severity of the following facial lines has an important psychological impact in adult patients, VISTABEL® is indicated for the temporary improvement in the appearance of:
    Moderate to severe vertical lines between the eyebrows seen at maximum frown (glabellar lines)
    Moderate to severe lateral canthal lines seen at maximum smile (crow’s feet lines)
    Moderate to severe crow’s feet lines seen at maximum smile and glabellar lines seen at maximum frown when treated simultaneously

  • This slide reviews the areas in the periorbital region that need to be considered during treatment

    Injections that are placed around the lower eyelid can compromise orbicularis oculi functioning. This is especially true in older patients, patients who have had lower eyelid surgery, and anyone with pre-existing lower lid laxity or ectropion
    The ‘‘snap test’’ or ‘‘lower lid extraction test’’ are useful tools in assessing lower lid tone in any patient who receives periorbital injections. Periorbital injections that may be well-tolerated in a younger patient may result in ectropion in the older patient. Keeping all injections outside the boundary defined by the infraorbital rim and a point 1cm lateral to the lateral canthus can significantly reduce this and other periorbital complications
    Other features to avoid in this area include the infraorbital nerve, the infraorbital artery and vein and the facial artery and vein

  • This slide reviews some of the potential complications when treating the periorbital region with fillers and neurotoxin

    Fillers
    Being aware of the position of blood vessels prior to treatment may reduce the risk of inadvertant injection of fillers in these structures and reduce the risk of necrosis. Injectors should be aware of blanching or sudden pain which can indicate blood vessel occlusion or compression

    Neurotoxin
    Also, injecting neurotoxin too low on the cheek can produce facial drooping
    Overtreatment of forehead lines with neurotoxin can make the patient appear frozen and unnatural
    Neurotoxin in the forehead area can alter the shape and position of the eyebrow so it is important to use low doses and exercise caution
    When treating crow’s feet it is important to stay outside of the orbital rim to avoid blurred vision

  • This slide provides information on the Tyndall effect which is a potential complication following treatment with HA fillers

    The Tyndall effect is a blue colouration that can appear when HA fillers are used below the eye. Avoid introducing fillers too superficially in the tear trough region to reduce the risk of the Tyndall effect
