Article Synopsis
  • A study evaluated the lifting capacity longevity of hyaluronic acid fillers through rheological properties in nine patients over one year.
  • The filler showed good maintenance of its lifting effect in most facial areas, except for slight improvements noted in the nasolabial fold.
  • It highlights the importance of selecting fillers with appropriate rheological characteristics for optimal aesthetic results after injections.

Background: Blepharoplasty alone cannot completely correct deep infraorbital grooves because of its limited ability to improve anatomical volume loss. As the concept of resolving periorbital fat atrophy to improve the infraorbital groove was introduced, several methods to properly fill the groove have been attempted. The purpose of this study was to present a new technique, involving the use of autologous fat from periorbital compartments, for infraorbital groove correction after lower blepharoplasty.

Article Synopsis
  • Soft tissue fillers are popular for facial contouring but can cause serious eye complications if improperly used, with no proven prevention or treatment for blindness related to these injections.
  • A literature review analyzed cases of visual impairment linked to filler injections, identifying nasal augmentation as the procedure with the highest risk, followed by glabellar wrinkle treatment.
  • The findings indicate that while the glabella was previously noted as the main site for blindness, the nose has become the most common area associated with severe visual compromise, highlighting the need for caution during these procedures.

Background: Small-bore needles reduce the complications associated with soft tissue filler injection. Gel particles must be sized appropriately to pass through fine-bore needles with an acceptable extrusion force. However, most soft tissue filler particles are larger than the inner diameter of the needle.

Background: Soft tissue filler injection is a common procedure for augmentation rhinoplasty. Various techniques for augmenting the nasal dorsum using a soft tissue filler have been attempted considering the size of the needle, the anatomical layer where the filler is injected, and the vascular distribution. The purpose of this paper was to evaluate the course of the dorsal nasal artery in patients scheduled for nasal augmentation using a soft tissue filler and to propose a method of nasal augmentation that minimizes vessel damage during soft tissue filler injection by confirming the distribution pattern of blood vessels through ultrasound.
