Head and Neck cancer reconstruction

Head and neck cancer reconstruction is one of the most complex and rewarding frontiers of reconstructive surgery. When a surgeon removes a tumor from the mouth, jaw, throat, or face, it often leaves a "defect" that affects a person’s ability to breathe, speak, swallow, or simply look like themselves. Reconstruction is the vital second half of the journey, using sophisticated microsurgery to "fill the gap" and restore both form and function.

1. What is it? Common Names for This Procedure

This surgery involves the transfer of tissue from one part of the body to the head or neck to repair the area where a cancer was removed.

• Common Names: Microvascular reconstruction, Free flap surgery, Head and neck restorative surgery.
• Key Techniques:
  • Free Flap Transfer (The Gold Standard): Taking a "block" of tissue (skin, muscle, or bone) along with its artery and vein from a distant site (like the leg or arm) and sewing those vessels into the neck under a microscope to provide a new blood supply.
  • Regional (Pedicled) Flap: Swinging a piece of tissue (like the pectoralis muscle from the chest) up into the neck while it stays attached to its original blood supply.
  • Skin Grafting: Using a thin layer of skin to cover a shallow wound.

2. Common Symptoms for Medical Consultation

Most patients are referred for reconstruction after a biopsy confirms a malignancy. Symptoms that lead to the initial cancer surgery (and subsequent reconstruction) include:

• Non-Healing Ulcers: A sore in the mouth or on the lip that hasn't healed in 3 weeks.
• Persistent Hoarseness: A change in voice that lasts longer than 2–4 weeks.
• Dysphagia: Difficulty swallowing or the sensation of food "getting stuck."
• Odynophagia: Pain upon swallowing.
• Facial or Neck Lumps: A new, firm mass that is often painless.
• Loose Teeth: Teeth that become loose without a clear dental cause.

3. List of Associated Diseases

Reconstruction is the primary solution for defects caused by:

• Squamous Cell Carcinoma (SCC): The most common type of head and neck cancer.
• Osteoradionecrosis (ORN): Bone death caused by previous radiation therapy, often requiring a new bone flap.
• Salivary Gland Tumors: Such as Mucoepidermoid carcinoma or Adenoid cystic carcinoma.
• Sarcomas: Rare cancers of the bone or soft tissue in the face.
• Advanced Skin Cancers: Such as Melanoma or Basal Cell Carcinoma that have invaded deeper structures.

4. List of Screening Tests for This Procedure

Before the "move," the surgical team must map out both the cancer and the "donor" tissue:

• CT or MRI with Contrast: To determine the exact size and depth of the tumor.
• CT Angiogram (CTA): Crucial for "Flap Mapping." This checks the blood vessels in your legs or arms to ensure they are healthy enough to be moved to the neck.
• PET-CT: To ensure the cancer hasn't spread to distant parts of the body before committing to a long reconstruction.
• Panendoscopy: A procedure under anesthesia where the surgeon looks at the throat, esophagus, and lungs to check for "second" tumors.

5. Am I Eligible for This Procedure?

• Cancer Resectability: The tumor must be able to be removed with "clear margins."
• Vascular Health: You must have healthy "donor" vessels. If you have severe peripheral vascular disease in your legs, a fibula flap may not be possible.
• Nutritional Status: Healing from a 10-hour surgery requires protein. Many patients need a temporary feeding tube (PEG) to "bulk up" before surgery.
• Smoking Status: Smoking is the #1 cause of flap failure. Many surgeons require a period of cessation because nicotine constricts the tiny vessels the flap relies on to live.

6. Pre and Post Care for This Procedure

Pre-Care:

• Dental Clearance: Any "bad" teeth in the area of radiation or surgery must be pulled before the procedure to prevent future bone infections.
• Speech and Swallow Baseline: Meeting with a therapist to record how you speak and eat before the changes occur.

Post-Care:

• The "Flap Check": For the first 48–72 hours, nurses will check the flap every hour using a Doppler (ultrasound) to listen for the "whoosh" of blood flow.
• Tracheostomy Care: Many patients have a temporary breathing tube in the neck to protect the airway from swelling. You will learn how to suction and clean this.
• Aspiration Precautions: You will likely be "NPO" (nothing by mouth) for 7–14 days while the internal stitches heal.
• Donor Site Care: Managing the wound on your arm or leg (where the tissue came from), which often involves a skin graft and a splint.

7. Days Required for Hospitalization

Because this involves airway management and intensive monitoring of blood vessels, the stay is significant.

• ICU/Step-down: 2 to 3 days.
• General Ward: 5 to 10 days.
• Total Stay: Typically 7 to 14 days.

Disclaimer: As per doctor’s advise, the number of days for hospitalization may get modified based on how quickly you transition from a breathing tube to natural breathing and your ability to safely swallow liquids.

8. Benefits of This Procedure

• Preservation of Speech: Using a thin, pliable flap to rebuild a tongue allows for much better word clarity than leaving the area to scar down.
• Functional Swallowing: Reconstruction prevents "strictures" (narrowing) that would otherwise make eating solid food impossible.
• Structural Integrity: A bone flap (fibula) prevents the "Andy Gump" deformity (the loss of the chin profile), allowing for dental implants later.
• Wound Coverage: It protects the "Great Vessels" (carotid arteries) in the neck, which could otherwise be exposed to the air or saliva after cancer removal.
• Psychological Restoration: It minimizes the visible "stigma" of cancer surgery, allowing patients to return to social and professional lives with confidence.
