Plastic surgery is a medical specialty concerned with restoring, repairing, or modifying damaged tissues and structures. Its scope is broadly defined by two primary applications: reconstructive and aesthetic procedures. Reconstructive surgery focuses on restoring function and physical appearance after trauma, severe disease, or congenital defect, involving the specialized techniques of tissue grafting, flap transfer, and skeletal realignment. The procedures aim to recreate biological integrity, managing issues such as compromised skin, damaged soft tissue, and impaired structural support. Aesthetic surgery addresses modifications to enhance form, though the underlying principles remain rooted in understanding human anatomy and biological tissue dynamics. The practice relies heavily on sterile surgical methods and an understanding of wound healing processes to achieve functional and structural improvement.
