![]() ![]() ![]() The cannula traversed through the lateral orbital rim underneath the periosteal layer to achieve a sufficient anchoring force between the cog thread and the periosteum. Via the secured insertion point, the catheter was advanced into the subperiosteal level of the lateral orbital rim and pushed through the anterior cheek to the inferior level, passing the nasolabial fold. The PDO cog thread (total length, 15 cm) was precannulated using a Medicut catheter type 18-G cannula (total length, 12.5 cm Mint THIN HansBiomed, Seoul, South Korea) (Fig. After local anesthesia administration, a stab incision was made on the skin just above the lateral orbital rim using an 18-G needle to secure an insertion point wide enough for the precannulated PDO cog thread to pass through. Before surgery, a local anesthetic solution was injected into the bilateral lateral canthus, and an additional infraorbital nerve block was performed. The patients did not undergo sedation before or after surgery rather, they underwent surgery in a fully conscious state. Herein, we show the effect of this technique in terms of both patient satisfaction and an objective assessment of the physical change in the midface area. 11– 13 In an effort to improve patient satisfaction, we used cog threads made of PDO material to perform a mini-midface lift that has a shorter operative time and postoperative downtime and yields satisfactory results without incisions or postoperative scarring. In recent years, especially in East Asia, polydioxanone (PDO) threads of various lengths and shapes have been approved for use, 9, 10 and many lifting procedures can now be performed in a much less invasive manner. Additionally, various complications can occur, 7, 8 burdening the decision-making process for the patients. However, these procedures require sedation or general anesthesia and a long recovery time for wound healing. ![]() ![]() 3– 5 The most representative conventional method involves a lower blepharoplasty incision with an extensive dissection of the subperiosteal layer, and the soft tissue is mechanically fixed in an upward direction through a device, such as an endotine, 6 followed by remnant skin excision. 1, 2Ī variety of conventional midface lifting techniques have been introduced to increase the volume of the reduced anterior cranial region and to correct soft tissue ptosis. Particularly in the case of the anterior cheek, which can signify youth, the downward migration of adipose tissue and volume can lead to a deeper-appearing nasolabial fold and an older-appearing face. As facial aging progresses, soft tissue ptosis occurs in every part of the face due to gravitational effects. ![]()
