Patient preparation: 

Medical History: The patient’s medical history must be evaluated, and questions answered concerning such disorders as diabetes or vascular diseases and smoking habits of patients that significantly influence the healing of wounds.  

Postoperative Expectations: Explain the recovery process mainly the time taken for recovery and any after care needed after surgery.  

Flap Planning: Before surgery the surgeon should plan the area for the flap and plan the incisions in the direction according to the defect size, and location, and direction of the skin tension lines also known as Langer’s lines.  

Postoperative Expectations: Explain the treatment plan, the time the body takes to heal completely and essential post-operation care.  

Physical Examination: The choice of flap depends more on the evaluation of the defect or lesion and how the surrounding tissue is to be handled.  

Patient position:  

Depending on the surgical area, the position of the patient should facilitate access to that area Properly. 

Step 1: Preoperative Planning: 

Evaluate the Defect Measure its dimensions, shape, and location, estimate the tension that will be needed to close the defect, as well as the availability of tissue over the surrounding area. 

Flap Design: A curved skin incision should then be drawn alongside the defect; most of them are semicircular in shape. The radius of the flap is 3 to 4 times the size of the defect. The flap design must be planned while considering the tissue laxity and blood supply. 

Mark the Incisions: 

Flap Outline: Outline the flap from a pivot point situated adjacent to the defect. The arc length of the flap will be proportional to the defect size. 

Tension Reduction Lines: If necessary, draw additional incisions (Burow’s triangles) at the base of the flap to allow better mobilization and to avoid dog-ear deformities. 

Step 2: Anesthesia: 

It may be local or general anaesthesia depending on the area, size of the defect, the status of the patient and the condition.  

Step 3: Incision and Elevation of the Flap: 

Cut the Flap: Make an incision along the marked line with a scalpel, staying within the dermis and subcutaneous tissue to preserve the blood supply. 

Elevation: To raise the flap, slightly peel it off adjacent tissue without severing the vessels supplying the skin (random pattern flap). This shift should not go to a point of over exaggerating the undermining effect beyond what is necessary. 

Step 4-Mobilization of the Flap:  

Rotation: Afterwards, rotate the flap into the defect so that the skin edges of the flap properly fit over the edges of the defect.  

Tension Release: To release the tension, some more triangular areas must be removed around the base of the flap. This enables the flap to rotate into that position without straining the tissues adjacent to it. 

Step 5-Flap Inset and Closure:  

Suture the Flap: Begin with the flap’s tip being sutured over the defect; proceed from there.  

Deep dermal sutures to reduce tension with the use of superficial sutures for skin approximation.  

Assess Flap Viability: One should make sure that the flap properly fits in the defect not to be tighten and the tissue edges should be well aligned. It is crucial that proper circulation is maintained for the flap to heal.  

Suture the Donor Site: If the flap donor site is too large to be closed primarily, then it needs grafting, and this area may heal by secondary intention healing.  

Step 6-Postoperative Care: 

Dress the Wound: If necessary, put appropriate dressings or the patient must follow the advice given for wound management. 

Use of topical antibiotics or sterile dressing as determined by site and size. 

Monitoring for Complications: Teach the patient about assessing for infection, necrosis or dehiscence. The viability checks and flap monitoring need to be through follow up appointments on the scheduled dates to monitor the healing process. 

Complications  

Flap Necrosis: 

Partial or total flap necrosis may occur due to poor blood supply. This is among the most critical complications. 

Risk factors include tension in the flap, poor design, or interference with the blood supply during surgery. 

Infection: 

Either donor site or recipient site infection can develop after surgery. 

Infections may delay healing, cause wound breakdown, or even flap failure if not treated appropriately promptly 

Wound Dehiscence: 

The flap or donor site may not heal satisfactorily, and the wound may break down (dehisce). 

This is more likely to occur when there is high tension on wound closure or infection. 

Flap Edema: 

Swelling in the flap may occur after surgery due to venous congestion or disruption to lymphatic flow. 

Flap Contracture: 

The flap can retract with tension over areas of significant movement and tension after a certain period. This will result in either functional deficits or poor aesthetic results.
