Debridement surgery: remove foreign bodies and blood clots in the wound, remove inactive tissues in the wound (dark purple, no bleeding, no pain), make necessary repairs to the wound margin, ensure smooth drainage, and strive to transform fresh contaminated wounds For fresh surgery, strive for the first phase of healing.

Chinese name

Debridement

Concept

Remove foreign bodies and blood clots in the wound, remove the inactive tissue in the wound (dark purple, no bleeding, no pain), make necessary repairs to the wound margin, ensure smooth drainage, and strive to transform fresh contaminated wounds into fresh surgical wounds To fight for the first healing

Processing method

Try to use mechanical cleaning such as rinsing to remove dirt and foreign matter on the wound surface.

Precautions

Maxillofacial wounded should be debrided as soon as possible after severe systemic conditions such as asphyxia, shock, and coma are resolved

Maxillofacial wounded should be debrided as soon as possible after severe systemic conditions such as suffocation, shock, and coma are resolved. Because the maxillofacial region is rich in blood flow and tissue regeneration is strong, it can be used for initial suture within 24 hours after injury. Although some neat wounds have passed 2-3 days, as long as careful debridement and suture, good healing results can still be obtained.

For wounds with deep wound cavities, curved wounds, and poor drainage, make an opposing hole in the wound bottom to make drainage smooth and promote wound purification.

First, try to use washing and other mechanical cleaning to remove dirt and foreign matter on the wound surface. Uneven wound edges can be slightly trimmed, and tissues should be kept as much as possible without extensive resection. All pedicled tissues should be retained even if the pedicles are small, and they should be restored as far as possible and sutured. For lacerations of the lips and facial skin, special attention should be paid to anatomical reduction. Use fine filaments for precise intermittent sutures.

2. Free tissue transplantation of isolated nose, lips, ear shells, eyebrows, arches and other tissues within a few hours of ex vivo is expected to survive. The excised tissue should be cleaned with normal saline, then immersed in an appropriate broad-spectrum antibiotic solution for 10-15 minutes, and then transplanted.

3. For deep trauma to the lower jaw, parotid gland and jaw bone injury that penetrates the mouth, debridement and suture are required to drain rubber bands. For wounds with a large tissue defect in the cheek, do not force the wound margin to be closed and sutured. This will cause scar contracture in the future, and it is difficult to open the mouth. After proper debridement and trimming of the wound margin, the wound margin of the oral mucosa and the wound margin of the skin Pull together suture to eliminate the wound, leaving the defect for later repair:

4. For those who have large maxillofacial trauma combined with tissue defect and large skin muscle flap open, the tissue flap should be properly reset and positioned and sutured so as to maintain near normal position without dislocation healing. The method of sewing can use a small rubber pad under the shirt button, and use thin stainless steel wire to sew through the button hole. When there is no stainless steel wire, nylon or silk thread can be used instead.

5. For simple rupture of parotid duct, line 0 can be used for anastomosis. A thin plastic tube is placed in the catheter, and one end is led out from the catheter port on the buccal mucosa and drained to the oral cavity. For the combined catheter injury, the broken port near the heart can be transferred to the buccal mucosa to avoid the occurrence of extraparotid fistula. The ruptured parotid gland should be sutured as much as possible, and the skin should be covered with a flap

6. For lacerations of the tongue, use a medium-sized silk thread to make a 1-2 stitch mattress suture. Put a small rubber patch under the knot before knotting to prevent the silk thread from embedding in the tissue when the knot is tight or when the tongue is edema after surgery. . The wound margin should be deep and slightly discontinuous suture.
