Head and Neck Cancer / Free-Flap Reconstruction | Existing website questions

After cancer removal, the defect may involve skin, mouth lining, muscle, cartilage or bone, and reconstruction must protect swallowing, speech, breathing and appearance. A free flap is tissue with its own blood supply taken from a distant donor site; its artery and vein are joined to suitable vessels in the neck. Because tissue can be made thin and pliable or bulky and padded, surgeons can tailor repair to the defect. Immediate reconstruction is critical to minimize complications and restore function and appearance. Microvascular free tissue transfer is described as the gold standard for reconstruction after ablative head and neck cancer treatment, with high success rates and versatility.

In head and neck cancer surgery, the tumour is removed and the resulting defect is repaired. A free flap is living tissue transferred from another body area, with its blood vessels disconnected and reattached microsurgically in the neck. The fibula flap can be shaped to fit the jaw defect, then fixed with screws and plates; it aims to restore jaw height and function, including chewing, speech and swallowing. Jaw reconstruction also depends on joint movement, dental support and soft-tissue repair, so outcomes vary with the defect and prior treatment. It is one option among several, and suitability depends on your health, defect size and cancer treatment.

The fibula is expendable for weight-bearing, yet harvest can affect ankle stability, mobility, strength and wound healing. Donor-site morbidity is often related to lower-leg anatomy and surgical technique. In one series of 157 patients, 31.2% had perioperative donor-site complications and 17% had long-term problems, including decreased ankle mobility 12%, hallux contracture 9%, leg weakness 8% and ankle instability 4%; 96% returned to preoperative ambulatory activity. Another report found delayed wound healing 17.4% and limited ankle range of motion 11.5%. Peroneal nerve injury can cause foot drop, pain and weakness. Wound dehiscence can expose tendons, and foot edema may occur. Surgical experience and meticulous technique help minimize long-term problems. These figures describe reported groups, not your personal risk.

Tongue reconstruction is planned to protect eating, speaking and swallowing. For larger defects, microvascular free tissue transfer is often preferred because it can be shaped to meet the palate, lips or teeth and support a functional swallow. Speech depends on tissue pliability and mobility, and long-term speech function varies with cancer size and location, reconstruction type, tongue movement, tracheostomy and motivation. With laryngeal preservation, most patients can communicate verbally and 85% have intelligible speech; after simultaneous total laryngectomy, about 50% regain phonation and 30% have intelligible speech. Reconstructive options include fasciocutaneous flaps such as radial forearm or anterolateral thigh flaps, and free tissue transfer has been associated with improved speech outcomes compared with pedicled flaps.

A free flap transfers living tissue with its blood vessels, which are reconnected microsurgically to repair defects after tumour removal. This allows skin, lining, muscle, cartilage or bone to be tailored carefully to the defect. Free tissue transfer is widely considered the gold standard after ablative head and neck cancer treatment because it can match tissue to the defect. Success depends on patient factors such as smoking, weight loss, fluid balance and overall health, and complications such as venous thrombosis usually occur within 48 to 72 hours after surgery, so close postoperative monitoring matters. The main benefit is precise tailoring to your needs, but success is not guaranteed and depends on individual factors.

A free flap moves living tissue with its blood vessels and reconnects them microsurgically to repair defects after tumour removal. Microvascular free tissue transfer can be tailored to the defect, and skin, oral lining, muscle, cartilage and bone may be reconstructed. Radiation can cause fibrosis and microangiopathic changes in recipient vessels, increasing anastomotic failure risk. Some studies report irradiation of the recipient site does not adversely affect successful free flap transfer in salvage surgery, while other evidence notes higher complexity after radiation. In poor-prognosis patients, methods allowing rapid recovery, such as an obturator after partial maxillectomy, may be considered. The choice depends on prognosis, defect and vessel quality.

Upper aerodigestive mucosal tumors often require intraoperative tracheostomy, and even minor resections may leave the endotracheal tube until swelling subsides. With a tracheostomy, the tube is left during early recovery so swelling can settle with a secure airway. The cuffed tube is used early, then exchanged for a fenestrated tube and corked to confirm the patient can manage before decannulation. The original tube should be secured at least three days for tract formation and may be changed after seven days if clinically indicated. Because free-flap pedicle pressure from ties can cause obstruction or thrombosis, ties are avoided and the tube is sutured in place. Airway care must be meticulous, with regular aspiration and a clean site.

Microvascular free tissue transfer is the gold standard after ablative treatment for head and neck cancers. A flap is living tissue moved with its blood supply, and surgeons can match tissue characteristics to the defect. Resection leaves defects that may need skin, oral lining, muscle, cartilage or bone reconstruction; flaps can be tailored thin and pliable or bulky and padded. Large composite defects often require free flaps, while smaller defects may be managed with local flaps or grafts. Success rates for free flaps in the head, neck and upper extremities are high, around 97 to 98 percent. Medical complications, not surgical complications, often cause slow recovery and prolonged hospital stay, so thorough preoperative medical evaluation and optimization are essential.
