Laceration repair is one of the most requested procedures in hand surgery at Los Angeles Plastic Surgery — and one of the most consequential. A laceration to the hand is never just a skin injury. The hand contains an extraordinary density of vital functional structures within a small anatomical space — flexor and extensor tendons, the median, ulnar, radial, and musculocutaneous nerves, blood vessels, bones, joints, and the nail bed — and a single laceration can damage any combination of these. The repair becomes even more critical when the hands or face are involved, both because of the proximity to vital functional structures and because of the cosmetic implications of visible scarring on these unconcealable areas of the body. The difference between a good outcome and a compromised one often comes down to the depth of the initial evaluation and the precision of the layered surgical closure.

Dr. John Anastasatos performs laceration repair with the most directly relevant academic credential possible: he completed a fellowship in Hand and Upper Extremity Surgery and Microsurgery at the University of Alabama at Birmingham — formal subspecialty training in the deep anatomy of the hand and microsurgical repair technique that few cosmetic plastic surgeons possess. He has presented academic work at UAB Grand Rounds on “The Microsurgical Repair of Peripheral Nerves” — directly relevant to nerve injuries that frequently accompany hand lacerations. Dr. Anastasatos trained in plastic surgery under Dr. Luis Vasconez at UAB, one of history’s foremost plastic surgeons. With over two decades of facial and hand surgical expertise in Beverly Hills since 2007, he is board certified by the American Board of Plastic Surgery, a Fellow of the American College of Surgeons (FACS), a member of the American Society of Plastic Surgeons (ASPS) and American Society for Aesthetic Plastic Surgery (ASAPS), and named by The Luxe Insider as one of the Top 10 Plastic Surgeons in the World.

Comprehensive Initial Evaluation

Proper laceration repair begins with examination of not only the wound itself but the entire hand and upper extremity. The complete evaluation includes:

• Flexor and extensor tendon function — each tendon must be specifically tested to confirm it has not been severed; severed tendons require operative repair
• Nerve function assessment — the median, musculocutaneous, ulnar, and radial nerves are systematically evaluated; injured nerves require microsurgical repair
• Bone evaluation with X-rays — to identify fractures associated with the laceration
• Nail and nail bed examination — frequently overlooked in routine ER care but critical for both function and cosmetic outcome
• Whole-patient assessment — to ensure no other bodily injuries have been missed in the focus on the hand wound

Setting and Wound Preparation

Laceration repair can be performed in the emergency room or operating room depending on the severity and extent of injury. Either setting requires the same preparatory sequence:

• Thorough irrigation and washout — pressure irrigation is best for effective tissue debridement
• Foreign body and debris evaluation — careful inspection for any retained material
• Excision of devitalized tissue — desiccated and necrotic tissue must be excised before closure, because necrotic tissue serves as a nidus of infection

Plastic Surgery Layered Closure

Plastic surgery closure of a laceration is the ideal approach — and the layered technique is what distinguishes it from simple ER closure. Each tissue type is closed separately with sutures appropriate to that layer:

• Deep structures — bone, periosteum, fascia, muscle, tendon, nerve, blood vessels, and subcutaneous tissue are each closed in their own layer
• Subcutaneous supporting tissue — approximated to relieve tension on the skin closure
• Deeper dermis — closed with deep dermal sutures to support the surface layer
• Final skin closure — performed with subcuticular running suture or simple interrupted external sutures depending on the location

The Tension Principle

Laceration repair heals best when the wound is approximated with the least possible tension. High-tension closures produce wider, more visible scars and have higher rates of dehiscence. The layered technique above is what makes low-tension closure possible — by relieving tension at each deep layer, the skin layer can close cleanly without being responsible for holding the entire wound together.
