Aim:
We developed a simple bipolar skin and subdermal hemostasis technique called the "Skin Subdermal Adhesion Technique" (SAT), which prevents postoperative complications and provides good cosmetic results.
Patients And Methods:
We performed 40 ptosis surgeries in 20 patients using SAT. All patients underwent bilateral excision of the excess skin due to age-related upper eyelid skin laxity; patients with facial nerve palsy and those who underwent manipulation of the levator muscle were excluded. The maximum wound width of the defect after skin resection and diameter after SAT were measured. Additionally, the presence or absence of postoperative complications requiring additional surgeries or procedures was investigated.
Results:
The mean (range) age was 76.0 (55-86) years. Among the bilateral resection widths, the diameter of the wider side was 11-20 mm (mean, 14.85±2.67 mm). In contrast, the defect width after SAT was 8-13 mm (mean, 9.75±1.84 mm). SAT reduced the maximum width by 34.3%. There were no cases of postoperative complications, such as wound hematoma formation or infection.
Conclusion:
SAT is useful for treating upper eyelid skin defects because it does not require any special equipment, is quick to perform, reduces the risk of postoperative complications such as hematoma, and provides good cosmetic results.

Clinical Applications of Epidermal Stem Cells
Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen...
