Resection and repair of plantar scars or chronic ulcers

Foot scar or chronic ulcer resection and repair of plantar scar or chronic ulcer resection, foot and foot scar rotation flap repair surgery, less pressure and friction of the heart, the scar can be repaired with medium-thickness skin. However, the heel and the sole of the foot are subject to large pressure and friction. The deep scar or the wound after the chronic ulcer is removed, such as the repair of the distal flap or the skin tube with no pressure, it is easy to form chronic ulcer after operation. Therefore, it is advisable to apply partial rotation flap repair of the sole as far as possible. Because the skin of the sole is poorly transported and the elasticity is small, the size should be appropriate when designing the flap. The ratio of length to width should not be greater than 1:1, otherwise the flap is prone to necrosis. Treatment of diseases: foot fractures, heel freckles Indication Flattened scars, hypertrophic scars, depressed scars, and atrophic scars that affect appearance, paresthesia, or function of affected parts. Contraindications a. a person with scars; b. inflammatory skin diseases such as chronic radiation dermatitis, purulent skin disease, recurrent herpes simplex, acne with obvious inflammation, xeroderma pigmentosum, etc.; c. abnormal blood diseases or coagulation mechanisms; d. Psychiatric patients or persons with various mental disorders; e. People with severe diabetes or heart, lung disease and severe hypertension. Surgical procedure 1 After local disinfection of the towel, the incision is designed along the scar boundary, and the anesthetic is used for infiltration anesthesia in the scar. 2 Cut the skin and subcutaneous tissue according to the designed incision to remove the scar tissue; when the scar area is too large or the tension is large, the method of fractional resection can be used, and the scar is gradually removed every two intervals of surgery for 3 months; Need to use other parts of the free flap transplantation to repair. 3 completely stop bleeding, can be sutured under the skin first, and then suture the skin intermittently. complication 1 Infection: Complications such as infection and poor wound healing may occur at the surgical site after scar removal. 2 local hematoma: scar resection surgery will cause facial skin and soft tissue damage, bleeding, hematoma, etc. may occur. 3 scar hyperplasia: the surgical incision may be linear depression or scar hyperplasia, once abnormal scars are found, it is advisable to go to the regular hospital for local dressing after 3-6 months of scar stabilization. 4 Wound cracking: mostly due to excessive scar removal, too much suture tension, or cracking of the wound due to intense activity of the patient.
