Neck Burn Contracture Release / Neck Scar Reconstruction | Release and coverage choices

Neck burn scars can tighten and restrict movement. For many contractures, release with a thick split-thickness skin graft is used; smaller tight areas may suit full-thickness grafts. Severe or extensive tightening, especially when the chin and chest are stuck together, may need regional or free flap coverage because local flaps are inadequate. Grafts can work well but may tighten again, so prolonged immobilization and pressure are important. If grafting fails or appearance is unsatisfactory, local flaps may be considered when tissue is available. The choice depends on scar extent, donor tissue, airway safety and prior surgery. Children may need repeated releases as they grow. A surgeon assesses these factors individually.

Full-thickness grafts can help counter contracture and restore flexibility, and one source notes they may give a superior functional and aesthetic result for focal neck contractures. Split-thickness grafts are commonly chosen for larger or diffuse areas because they can be a single-stage procedure, blend with surrounding scarred skin, need less operating time, and have minimal donor-site morbidity. They are also suitable for mild to severe cases. A thick split-thickness graft is often used for neck release, with bolster care and prolonged neck splinting to reduce recurrence. Split-thickness grafts represent like tissue and blend into the area when neck contractures are extensive. Thicker grafts may reduce contracture severity.

Neck burn contracture release can use split-thickness or full-thickness skin grafting, local flaps, tissue expansion or a free flap. Most anterior neck contractures are satisfactorily treated with release and skin grafting. Local flaps may help smaller scar bands, but nearby tissue is often burned and unavailable, and they are not useful for moderate contractures. When grafting is unsuccessful because of recurrent contracture or poor aesthetics, local flap reconstruction can be excellent if tissue is available. Even then, surrounding scar may create tension and vascular compromise. The important trade-off is better cover where tissue is available, with the risk that scar tension can still affect the flap.

Neck burn contractures range from mild bands to severe flexion deformities. Many are released and covered with a thick split-thickness skin graft, sometimes staged first to protect the airway. Once stable, tissue expansion can expand unburned lateral neck or supraclavicular skin to replace the grafted area. Free flaps are advocated for anterior neck contractures but require microsurgical technique and carry complete flap loss risk; they can be bulky and need revisions. The choice depends on scar location, size and traction direction, plus patient factors and available donor skin. A free groin flap may be an alternative when standard flaps are unavailable, and children may need repeated releases as they grow.

Neck burn scar contracture pulls the chin toward the chest and can flatten the cervicomental angle, limiting movement. Release is often planned at the hyoid level to emphasize that angle; the incision follows the cervicomental line to a scar-free plane, including platysma division, then is spread with traction and carefully overcorrected because healing can re-contract. Resurfacing may use a thick split-thickness skin graft, sometimes staged for airway safety, or a flap when the defect is too large; a full-thickness graft stitched along the submental line can create a subtle natural contour, and long-term splinting may help reduce recurrence after grafting, with careful follow-up planning.

Neck burn contractures can pull the chin, cheeks and lower lip downward, and tension in facial scars can worsen hypertrophic scarring. In operative management, the neck is usually released first, followed by the lower lip and lower eyelids, because lower-lip ectropion may improve or resolve after neck release. Extensive contractures usually require split-thickness skin grafting, while focal contractures may suit full-thickness grafting; local flaps may be considered if grafting is unsuccessful or unsatisfactory. Split-thickness grafts represent like tissue and blend into the area, and full-thickness grafts can help restore flexibility. If the lip remains incompetent, more targeted lip reconstruction may be needed. A stable release may later be resurfaced with tissue expansion or flap when unburned skin is available.

Release is usually by incision rather than excision, carried to a scar-free plane; scars may spread from chin to chest or abdomen, but only neck scars may be excised. The goal is a mobile, supple neck, not removing every scar. Depending on severity and extent, techniques include split-thickness or full-thickness skin grafting, local flaps, tissue expansion, or free flap; the majority of neck contractures can be managed with a thick split-thickness skin graft. Resurfacing may use grafts or flaps; durable correction requires tissue that maintains elasticity and resists secondary contraction. Severe contracture can affect airway access, so anesthesia planning matters. In children, releases may need repeating as they grow, and long-term splinting can reduce recurrence.

Neck burn contracture reconstruction can involve skin grafting, dermal substitutes, local flaps, tissue expansion and distant or free tissue transfer. A flap may provide better color match and elasticity than a graft. Once a stable neck release is obtained, the grafted area may sometimes be replaced later by expanding unburned skin from the lateral neck or supraclavicular area. Local flap reconstruction may be considered when split-thickness skin grafting is unsuccessful or does not give a satisfactory aesthetic result. Full-thickness skin grafts can also help counter contracture and restore flexibility. The choice depends on scar extent, donor tissue and functional goals.

Release is carried to a scar-free plane, often including platysma division, then the wound is spread with digital traction or retractors while the neck is extended as much as possible and slow continuous traction is applied. The incision typically runs along the cervicomental angle from mid axis to mid axis or further if needed. Overcorrection matters because secondary contracture occurs with healing. Care is taken to avoid injury to neurovascular structures deep to the platysma. Airway safety is central: anesthesia consultation is critical, fiberoptic intubation may be used, and in severe cases the surgeon should be present for possible emergent release.
