Rebuilding massive facial, neck, and skull base defects following advanced cancer eradication. Dr. Manish Tiwari utilizes the Rectus Abdominus Free Flap to transplant robust, highly vascularized abdominal tissue to safely seal and reconstruct the most complex head and neck voids.
Providing massive muscle bulk to safely seal the brain cavity from the oral and nasal airways after extreme resections.
Covering exposed, vital carotid arteries after massive neck skin loss due to tumor removal.
Transplanting substantial abdominal muscle volume to replace the entire tongue and restore swallow dynamics.
Replacing dead, heavily irradiated neck skin with healthy, robust, living abdominal tissue to prevent fatal infections.
When advanced cancers require the removal of massive sections of the face and neck, creating large "dead spaces," thin flaps will not work. The Rectus Abdominus (abdominal core muscle) provides the vital bulk needed to prevent fluid accumulation and catastrophic vessel blowouts.
The Rectus Abdominus allows Dr. Tiwari to harvest a massive block of muscle, fat, and skin. This is absolutely critical for obliterating large surgical cavities, particularly in the maxilla or deep neck spaces, restoring natural facial contours.
This flap is supplied by the Deep Inferior Epigastric Artery (DIEA). It provides incredibly long, robust blood vessels, allowing Dr. Tiwari to easily reach unaffected blood vessels in the neck—even after extensive radiation.
Because the donor site is on the abdomen, a second surgical team can easily harvest the flap at the exact same time Dr. Tiwari is removing the head and neck tumor. This drastically reduces the total time under anesthesia.
Safely relocating abdominal tissue to the head and neck requires extreme precision and highly coordinated surgical teams.
The primary tumor and affected lymph nodes are radically excised. The surgical team maps the dimensions of the resulting defect to guide the abdominal harvest.
A precisely measured section of the rectus muscle, overlying fat, and skin is lifted from the abdomen, ensuring the deep inferior epigastric blood vessels are preserved.
The bulky abdominal tissue is transferred to the head. Dr. Tiwari uses high-powered microscopes to meticulously sew the abdominal vessels into the neck arteries, restoring blood flow instantly.
Ensuring the abdomen is a safe donor site is the first step.
Recovery requires healing both the complex head/neck defect and the abdominal donor site.
