Reconstruction of Complex wounds

Everyone experiences some type of injury in life. Most of the time, these wounds heal on their own or are managed by simple sutures. But sometimes, the wound fails to heal or is so large and complicated that it can’t be simply sutured. With high-speed vehicles, machine industries and advanced weapons, complex wounds are seen more often in today’s world. Such complex wounds need a different approach and plastic surgeons’ expertise.

In this comprehensive guide, we will explore complex wounds, how they develop, and how a Plastic surgeon plays a key role in their management. We will also discuss various surgical options, alternatives, pre-procedure preparations, the procedure itself, aftercare, recovery, expected results, costs, and potential risks.

1. What is a complex wound?

The wounds that can’t be managed by simple dressing or just by putting sutures are called complex wounds. Some features of complex wounds:-

It involves multiple structures like skin, muscle tendon, nerve vessels or bone with loss of some or all of these in the wound. Skin loss is most common, making it impossible to close the wound directly by sutures.
The area of injury is extensive, involving a large part of the body.
The injury involves multiple parts of great functional and cosmetic importance like eyelids, nose, lips, etc.
Long-standing wounds that don’t heal, like bed sores, radiation ulcers, lymphedema, etc.

2. What are the causes of a complex wound?

Following are some common causes of complex wound:-

Road traffic accidents, especially high-velocity
Injury by machine in the agriculture field or in the industrial zone
Injury by a sharp, heavy weapon on the face
Explosion injury by crackers or bomb
Burn injury or high-voltage electric burn
Non-healing wound with infection of bone
Bedsore, fistula, radiation ulcer

3. What are the problems of complex wounds?

Physical Problems:
- Chronic Pain: Extensive wounds and non-healing wounds lead to pain. In addition, frequent dressing requirements also lead to pain. This pain can limit mobility and hinder everyday activities.
- Poor function: The loss of skin, muscle tendon, bone and nerve leads to poor function of the limb. Injuries on the face may lead to loss of eyelid closure or mouth opening. If such complex wounds are allowed to heal without proper reconstruction, permanent disability may be there.

Socioeconomic impact:
- Social impact: Carrying large wounds with bulky dressing, loss of function with disabilities, and frequent hospital visits lead to feelings of self-consciousness and discomfort in social situations.
- Reduced Physical Activities: Engaging in physical activities or sports may be challenging due to the physical limitations caused by large wounds. This limitation can impact overall health and fitness.
- Economic burden: Complex wounds require prolonged hospital stays, frequent hospital visits, and multiple surgeries. All these put a tremendous strain on the financial status of the patient and family.

Psychological Issues:
- Loss of job, extensive scar, and prolonged medical treatment often lead to anxiety, depression and low self-esteem.

4. How do plastic surgeons treat such complex wounds?

The complex wound may require a multidisciplinary approach as sometimes life-threatening injuries co-exist. Once life-threatening injuries are managed, the Plastic surgeon takes care of these complex wounds. A plastic surgeon analyzes each injured structure and makes a reconstruction plan accordingly. All components of the wound are treated meticulously. Here are some modalities that are used for reconstruction of complex wounds:

Advanced dressings: Biological dressing, artificial skin, Integra, negative pressure wound therapy, hyperbaric oxygen therapy, etc.

Grafting: Split-thickness skin graft, full-thickness skin graft, pixel graft, tendon graft, nerve graft, vessel graft

Flaps: skin, muscle or bone flap, microvascular flap, propeller flap, perforator flap

Anatomical closure: Sometimes, the wound may look extensive and horrific, but there is no tissue loss. In such cases, meticulous repairing of each structure in its normal anatomical status will lead to complete wound closure with excellent functional and cosmetic outcomes.

Functional repair: A plastic surgeon always considers the functional aspect first and the cosmetic secondary. Sometimes, injury is so extensive that the hand will invariably have some loss of function. But plastic surgeons may repair hands in more functional condition. A functionally better but cosmetically inferior hand is far better and more useful than a cosmetically better-looking non-functional hand.

5. What happens before the procedure?

Before starting your surgery for a complex wound, several critical steps ensure that you are well-prepared for the surgery:

– Consultation: The complex wound may require a multidisciplinary approach as sometimes life-threatening injuries co-exist. Once life-threatening injuries are dealt with, the Plastic surgeon takes care of these complex wounds. The process typically begins with a consultation with a plastic surgeon. During this meeting, you will discuss your goals, medical history, and any concerns. The surgeon will evaluate your candidacy for the procedure. Your surgeon will discuss what you can expect from the procedure, including potential risks and complications. Having realistic expectations and a clear understanding of the process is crucial.

– Medical Evaluation: A comprehensive medical evaluation is crucial to assess your overall health. Your surgeon will review your medical history, perform physical examinations, and may request additional tests to ensure that you are fit for surgery. Before and after photographs of other patients may be shown to you. It helps in better understanding the final outcome.

– Formulation of Plan: Your surgeon will create a customized treatment plan based on your goals and evaluations. This plan outlines the incisions, the donor site for graft or flap, the surgical technique to be used, and the expected scar line. Many times, multiple surgeries may be needed. Practical matters, such as payment and scheduling, will also be addressed during this phase. Ensure that you clearly understand the financial aspects and post-operative appointments.

– Pre-operative Instructions: You will receive detailed pre-operative instructions. These may include dietary guidelines, medications to avoid, and instructions for quitting smoking, if applicable. Following these instructions is essential to ensure a safe surgery and smooth recovery.

6. What happens during the procedure?

There are various approaches to complex wound surgery. The essential components of all are:

Anaesthesia: The procedure begins with the administration of anaesthesia. Most of the time, general anaesthesia is needed to ensure your comfort during the procedure.

Cleaning of the wound: Once under anaesthesia, the wound is thoroughly cleaned, and all infected materials are removed. If the wound is too dirty, multiple sitting surgeries may be needed.

Repair of each structure: All injured structures (skin, muscle, bone, nerve, tendon, etc) are repaired. A graft or flap may be needed from another part of the body.

Wound closure: The wound may be closed by sutures, graft, or flap.

Dressing: At the end of the procedure, the dressing is placed. Often, special dressing with a splint is needed.

Monitoring: After the procedure, you will be closely monitored to ensure your safety and comfort. Vital signs such as blood pressure, heart rate, and oxygen levels are continuously assessed.

7. What aftercare is needed?

After the completion of the procedure, proper aftercare is essential for a smooth and successful recovery. Here are the key elements of post-operative care:

Prevention of infection: As complex wounds are often infected, some sort of antibiotics are always needed to prevent skin infection. Often, a prolonged course of antibiotics is given, but different hospitals have different policies on antibiotics and their duration.

Pain Management: Pain and discomfort are common after any surgery. Your surgeon will prescribe pain medication to manage pain during the initial recovery period.

Hydration and Nutrition: Some form of fluid can be given in your veins to maintain adequate hydration and nutrition.

Dressing and Compression Garments: After surgery, a variety of dressings is put on depending on the type of reconstruction.

Activity Restrictions: Following your surgeon’s recommendations regarding physical activity is crucial.

8. What is the usual recovery period?

Depending on the type of wound and surgery, the recovery may take a few days to several months. The duration of full recovery varies based on the extent of the injury, repair and individual healing factors.

9. What is the expected cost of the procedure?

The cost of surgery for complex wounds can vary widely depending on several factors like extent of injury, infection, location of the hospital, hospital set-up, surgeon, anaesthesia type, type of reconstructive surgery and number of surgeries. You may need to consider other expenses, such as pre-operative tests, post-operative dressings, and follow-up appointments.

10. What are the possible risks and complications of this procedure?

No surgical procedure is free from risk and complications. The same holds true for complex wound surgery. Like any surgery, this procedure carries certain risks and potential complications. It’s crucial to be informed about these possibilities:

Bleeding: Excessive bleeding during or after the procedure is rare but possible. Surgeons take measures to minimize this risk.

Infection: As such surgeries are done for complex or long-standing wounds, infections can occur after surgery and may require treatment with antibiotics. Infection may result in loss of graft or flap.

Graft or flap loss: Loss of small or entire graft/flap, particularly in a large infected or a burn wound, is not uncommon. A small patchy area heals by on its own. Complete graft loss or a large patch of lost graft may need another session of skin grafting or flap.

Uneven Results: In some cases, graft or scar contracture may result in uneven contours or irregularities. Skin graft shortens with time, and this may lead to functional problems, especially when on joints or near mobile areas. Revision surgery may be necessary to correct these issues.

Scarring: The strategic selection of graft donor area results in minimal and hidden scarring. Scar often fades with time. However, scarring can vary from person to person, and a thick scar can be formed in some people
