Reconstructive Surgery — How It Works, Benefits & Recovery — Procedure Guide, Recovery & Risks | MyMedicPlus

Reconstructive surgery restores anatomy, function, and appearance following cancer resection, trauma, burns, infection, or congenital anomalies. Unlike cosmetic surgery, which enhances the appearance of a structurally normal body, reconstructive surgery addresses structural defects that impair normal function or are significantly outside the range of normal appearance. Reconstructive surgeons apply the principle of the reconstructive ladder — a hierarchy of increasing complexity — selecting the simplest technique that achieves a reliable outcome: primary closure (direct wound edges together) at the lowest rung, then skin grafts (partial-thickness or split-thickness from a donor site), local flaps (tissue moved from adjacent areas while maintaining blood supply), regional pedicled flaps (tissue moved on a vascular pedicle from a nearby area, such as the latissimus dorsi myocutaneous flap or the pedicled TRAM flap for breast reconstruction), and at the most complex rung, microsurgical free tissue transfer. The choice depends on defect size, location, tissue type required, patient health, and prior radiation therapy. Reconstructive surgery is provided across many surgical subspecialties — plastic surgery, orthopaedic oncology, neurosurgery, ENT, and oral-maxillofacial surgery — often in multidisciplinary teams. Reconstructive surgery restores form and function to body parts damaged or lost through trauma, cancer, burns, infection, or congenital conditions. Unlike cosmetic surgery — which is purely elective — reconstructive surgery addresses functional deficits or deformities that impair quality of life. Major reconstructive domains include breast reconstruction after mastectomy, head and neck reconstruction following cancer ablation, hand and upper extremity reconstruction, lower limb salvage for complex wounds, burns reconstruction including skin grafting and contracture release, and congenital anomaly correction including cleft lip/palate, craniosynostosis, and hypospadias. Reconstructive surgery uses a hierarchical approach — the reconstructive ladder — from simple wound closure through skin grafting, local flaps, regional flaps, to free microvascular tissue transfer. Microsurgery — anastomosing vessels and nerves under magnification — enables transfer of composite tissue (muscle, skin, bone) from distant donor sites to complex defects where no local tissue is available. Modern reconstructive surgery is increasingly augmented by alloplastic implants, tissue expanders, biological scaffolds, and emerging techniques such as vascularised composite allotransplantation (face and hand transplantation) and bioengineered tissue constructs.

The main clinical scenarios requiring reconstructive surgery include breast reconstruction after mastectomy for breast cancer (immediate or delayed), head and neck defect reconstruction after oncological resection (jaw, tongue, palate, scalp, facial skin), limb salvage and coverage after bone or soft tissue sarcoma surgery, burn wound coverage over large surface areas, trauma wound closure (degloving injuries, open fractures, exposed hardware), cleft lip and palate repair in infants, congenital craniofacial anomaly correction (craniosynostosis, hemifacial microsomia), pressure ulcer closure in paraplegic patients, and hand surgery for tendon, nerve, and vascular injuries. Oncological reconstruction is particularly important where adjuvant radiotherapy is planned — reconstructed tissues must provide reliable coverage before radiation begins, as irradiated tissue is poorly vascularised and heals inadequately. Patients undergoing pelvic exenteration for recurrent colorectal or gynaecological cancer require perineal reconstruction using VRAM (vertical rectus abdominis) or gracilis flaps. Patient fitness for prolonged general anaesthesia, nutritional status, and comorbidities (particularly smoking, diabetes, and peripheral vascular disease) significantly affect reconstructive options.

Reconstructive planning begins pre-operatively: defect assessment, recipient vessel identification by Doppler or CT angiography, donor site selection, and template design. For free flap reconstruction — the most technically demanding technique — the patient undergoes general anaesthesia and the procedure proceeds simultaneously at two operative fields: the ablative surgery creating the defect and the flap harvest. Common free flaps include the DIEP (deep inferior epigastric perforator) flap from the abdomen for breast reconstruction, the anterolateral thigh (ALT) flap from the lateral thigh for head and neck or lower limb defects, and the free fibula osteocutaneous flap for mandibular reconstruction. The flap is harvested on its nutrient artery and vein(s). The pedicle vessels are divided and the flap transferred to the defect. Microvascular anastomosis (joining of vessels 1–3 mm in diameter under an operating microscope at 10–20× magnification) connects the flap artery to a recipient artery and flap vein to a recipient vein. Anastomotic patency is confirmed by Doppler, and perfusion assessed visually. The flap is inset into the defect and the donor site closed primarily or with a skin graft. Procedures last 4–8 hours for major free flap cases. For free flap reconstruction — the most advanced reconstructive technique — the surgeon raises composite tissue (e.g., anterolateral thigh flap, fibula free flap, rectus abdominis free TRAM flap, deep inferior epigastric perforator — DIEP flap) by identifying and dividing the pedicle (artery and vein) from the donor site. The flap is transferred to the recipient site where the pedicle vessels are anastomosed to recipient vessels under operating microscope magnification at 10–25x. Patency is verified with Doppler signal. The donor site is closed primarily or grafted. Post-operative flap monitoring — hourly observation of colour, temperature, capillary refill, and Doppler signal — detects vascular compromise early, enabling return to theatre for salvage. Free flap success rates exceed 95% at specialist centres with experienced microsurgeons.

Free flap success rates exceed 95% at experienced specialist centres — meaning the flap survives and achieves its reconstructive goal. Partial flap loss (requiring additional grafting) occurs in 3–8%. The DIEP flap for breast reconstruction achieves natural, lasting results in over 85% of patients with long-term patient satisfaction consistently superior to implant-based reconstruction in prospective studies. Functional head and neck reconstruction with free flaps restores acceptable speech in 80–85% of patients and adequate oral intake in over 85%. Mandibular reconstruction with the free fibula provides sufficient bone stock for dental implants in most patients. Breast reconstruction significantly improves quality of life, body image, and psychological wellbeing after mastectomy — randomised data from the BRAVO trial demonstrate superior BREAST-Q scores for immediate versus delayed reconstruction. Complex lower limb reconstruction avoids amputation in 85–90% of carefully selected limb salvage cases where the alternative is above-knee amputation.

Free flap complications include total flap loss (1–5%) from arterial or venous thrombosis at the anastomosis — requiring emergency return to theatre within 4–6 hours of detection for salvage; partial flap necrosis from zone-of-perfusion ischaemia; wound dehiscence at the inset margins; haematoma formation under the flap; seroma at the donor site; and wound infection. Donor site morbidity is significant for some flap types: DIEP harvest risks abdominal wall weakness or hernia (1–3%); fibula harvest causes temporary ankle weakness and foot numbness; radial forearm flap leaves a visible forearm scar and donor skin graft. Prolonged general anaesthesia in complex cases increases the risk of DVT, pulmonary embolism, respiratory complications, and pressure injuries. In previously irradiated fields, anastomotic and wound healing complications are elevated compared to non-irradiated recipients — radiated recipient vessels are thickened and prone to intimal injury. Re-operation for flap revision, symmetrisation, scar refinement, or donor site revision is commonly performed 6–12 months after the primary reconstruction.

Free flap patients require hourly clinical flap monitoring for the first 48 hours — assessing colour, capillary refill, temperature, and Doppler signal — to detect vascular compromise before irreversible necrosis occurs. Any clinical deterioration triggers immediate return to theatre for anastomosis revision. Hospital stay is 5–7 days for major head and neck or breast free flap cases; simple local flap or skin graft patients are discharged in 2–4 days. Dressings are changed under strict aseptic technique; compression garments are applied for thigh and abdominal donor sites. Physiotherapy for range of motion, swallowing rehabilitation (speech and language therapy for head and neck cases), and occupational therapy begin during the admission. Oral nutritional supplementation supports wound healing. Return to light activities occurs at 4–6 weeks; physical work and exercise at 8–12 weeks. Revision surgery for cosmetic refinement or functional improvement is planned at 6–12 months. Reconstructed patients receiving post-operative radiotherapy are advised to complete all wound healing before starting radiation, typically at 6–8 weeks post-operatively.
