Abstract:
Reconstruction of a temporal bone defect after tumor ablation should provide watertight filling and adequate resurfacing. A muscle-sparing rectus abdominis musculocutaneous (ms-RAMC) flap with de-epithelized skin paddle has been used and early experience was reported. Case series enrolled 7 patients who underwent free ms-RAMC flap after tumor ablation for external auditory canal cancer. Vertically oriented flap was harvested with central strip of muscle. Distal skin paddle was de-epithelized to fill the bony defect. Immediate facial nerve reconstruction was performed whenever indicated. The average operation time for reconstruction was 280 minutes. No early complication was reported. An ms-RAMC flap with de-epithelized skin paddle can be used for temporal bone defect reconstruction with its anatomic consistency and technical simplicity. It can provide sufficient bulk for water tight packing that lasts after irradiation. The 11th intercostal nerve can be harvested during pedicle dissection. Muscle sparing technique could minimize donor-site morbidity.
