Third-Degree Burn Scars: Things You Need to Know

by Ella

Third-degree burns, also known as full-thickness burns, are the most severe type of burn injury. They extend through the entire thickness of the skin, destroying both the epidermis and dermis, and can affect underlying tissues, such as muscles, bones, and tendons. These burns often result in significant scarring and long-term functional and aesthetic challenges. This article provides comprehensive information on third-degree burn scars, covering causes, symptoms, diagnosis, treatment, and recovery.


Understanding Third-Degree Burns

Causes of Third-Degree Burns

Third-degree burns can result from various sources, including:


Thermal Burns: Caused by exposure to high temperatures, such as flames, hot liquids, or steam.


Electrical Burns: Resulting from contact with electrical currents, which can cause deep tissue damage.


Chemical Burns: Occurring when the skin comes into contact with strong acids, alkalis, or other corrosive substances.

Radiation Burns: Due to exposure to high levels of radiation, such as during industrial accidents or radiation therapy.

Friction Burns: Resulting from intense friction, often seen in accidents involving road surfaces or machinery.

Symptoms of Third-Degree Burns

Third-degree burns exhibit several distinct symptoms:

Skin Appearance: The affected area may appear white, charred, or leathery. Unlike less severe burns, third-degree burns can be numb due to nerve damage.

Lack of Pain: Initially, third-degree burns might not be painful because nerve endings are destroyed. However, pain can occur around the burn area where less severe burns are present.

Swelling: Significant swelling can occur as the body responds to the injury.

Dehydration and Shock: Severe burns can lead to fluid loss, resulting in dehydration and shock, which are medical emergencies requiring immediate attention.

Diagnosis and Initial Treatment

Diagnosing Third-Degree Burns

Accurate diagnosis of third-degree burns is crucial for effective treatment. Healthcare providers typically use the following methods:

Visual Examination: Assessing the burn’s appearance, size, and depth.

Rule of Nines: A method to estimate the total body surface area (TBSA) affected by the burn, which helps in determining the severity and treatment plan.

Burn Depth Assessment: Using tools such as laser Doppler imaging or histological examination to determine the exact depth of the burn.

Initial Treatment

Immediate medical care is essential for third-degree burns to prevent complications and stabilize the patient:

Fluid Resuscitation: Administering intravenous fluids to replace lost fluids and prevent shock.

Pain Management: Providing pain relief through medications, despite the initial numbness.

Wound Care: Cleaning the burn area and applying dressings to prevent infection.

Tetanus Shot: Administering a tetanus shot if the burn is caused by an injury that could introduce tetanus spores.

Healing Process and Scar Formation

Phases of Burn Healing

Burn healing is a complex process that occurs in several stages:

Inflammatory Phase: The body’s immediate response to injury, characterized by redness, swelling, and heat. This phase involves removing debris and bacteria from the wound.

Proliferative Phase: New tissue begins to form. Fibroblasts produce collagen, and new blood vessels develop to supply nutrients and oxygen to the healing tissue.

Maturation Phase: The final phase involves remodeling the new tissue to improve strength and function. This phase can last for months to years.

Scar Formation

Third-degree burns often result in significant scarring due to the extensive tissue damage and healing process. Key types of scars include:

Hypertrophic Scars: Raised, red scars that stay within the boundaries of the original wound. They form due to excessive collagen production during the healing process.

Keloid Scars: Overgrown scars that extend beyond the original wound boundaries. They can become large and cause discomfort or functional limitations.

Contractures: Scars that cause the skin to tighten, which can restrict movement and impair function. Contractures often occur over joints and require specialized treatment to manage.

Treatment Options for Third-Degree Burn Scars

Surgical Interventions

Surgical treatments are often necessary to address the severe scarring and functional impairments caused by third-degree burns:

Skin Grafting: Transplanting healthy skin from another part of the body to cover the burn wound. Grafts can be split-thickness (involving the epidermis and part of the dermis) or full-thickness (involving the entire dermis).

Flap Surgery: Using nearby tissue with an intact blood supply to cover the burn wound. Flap surgery can provide better aesthetic and functional outcomes compared to skin grafts.

Contracture Release: Surgical procedures to release tightened skin and improve mobility, especially over joints.

Z-Plasty: A technique that reorients scar tissue to reduce tension and improve the range of motion.

Non-Surgical Treatments

Non-surgical treatments can also play a significant role in managing third-degree burn scars:

Pressure Therapy: Wearing custom-fitted pressure garments to reduce hypertrophic and keloid scar formation. Pressure therapy is typically used for several months after the burn heals.

Silicone Gel Sheets: Applying silicone gel sheets or ointments to the scar can help soften and flatten hypertrophic scars.

Laser Therapy: Using lasers to reduce scar thickness, improve texture, and alleviate discomfort. Laser therapy can target blood vessels in the scar tissue and stimulate collagen remodeling.

Cryotherapy: Freezing scar tissue to reduce keloid and hypertrophic scars. This treatment is often combined with other therapies for better results.

Rehabilitation and Physical Therapy

Rehabilitation is a critical component of burn care, helping patients regain function and mobility:

Physical Therapy: Customized exercises and stretching routines to improve the range of motion, strength, and flexibility. Physical therapy can also help prevent contractures and improve overall functional outcomes.

Occupational Therapy: Assisting patients in adapting to daily activities and using assistive devices if needed. Occupational therapists can also provide splints to maintain proper joint positioning and prevent contractures.

Psychological Support: Counseling and support groups to address the emotional and psychological impact of burn injuries and scarring. Coping with changes in appearance and function can be challenging, and psychological support is crucial for overall recovery.

Preventing and Minimizing Scarring

Early Intervention

Early intervention and appropriate wound care can significantly reduce the risk of severe scarring:

Prompt Medical Attention: Seeking immediate medical care for burn injuries to ensure proper wound management and minimize complications.

Wound Care: Keeping the wound clean, moist, and covered to promote optimal healing conditions. Following healthcare provider instructions for dressing changes and wound care.

Infection Prevention: Using antibiotics and other measures to prevent infection, which can worsen scarring and delay healing.

Scar Management Strategies

Implementing effective scar management strategies can improve the appearance and function of burn scars:

Moisturizing: Regularly moisturizing the burn area to keep the skin hydrated and prevent dryness, which can exacerbate scarring.

Massage Therapy: Gently massaging the scar tissue to improve blood flow, reduce stiffness, and promote collagen remodeling.

Sun Protection: Protecting the scar from sun exposure to prevent discoloration and further damage. Using sunscreen and covering the scar with clothing or bandages when outdoors.

Regular Follow-Up: Attending regular follow-up appointments with healthcare providers to monitor scar progress and adjust treatment as needed.

Long-Term Care and Support

Living with Burn Scars

Living with third-degree burn scars can present ongoing challenges, both physically and emotionally. Adopting a holistic approach to care and support is essential for long-term well-being:

Acceptance and Coping: Accepting the changes in appearance and function can be difficult. Support from family, friends, and healthcare professionals can help individuals cope and build resilience.

Support Groups: Joining support groups for burn survivors can provide a sense of community and shared experiences. Hearing from others who have faced similar challenges can be encouraging and empowering.

Educational Resources: Accessing educational resources about burn injuries and scar management can help individuals make informed decisions about their care and treatment.

Advances in Burn Care

Ongoing research and advancements in burn care continue to improve outcomes for individuals with third-degree burns:

Regenerative Medicine: Exploring the use of stem cells and tissue engineering to promote skin regeneration and reduce scarring.

Advanced Wound Dressings: Developing new wound dressings that enhance healing, reduce infection risk, and minimize scarring.

Telemedicine: Utilizing telemedicine to provide remote consultations and support for burn patients, improving access to specialized care.
