Background:
Microvascular free-tissue transfer is a widely used technique for surgical site reconstruction following head and neck mass resection. While it is commonly used in adults, the rarity of head and neck cancers in children makes free flap reconstruction relatively rare in this population. Free flap reconstruction allows for coverage of large defects which may result from wide resections performed to avoid exposing pediatric patients to primary radiotherapy.
Case Description:
We present two pediatric oncologic cases using free flap reconstruction. The first, a 4-year-old male, presented with a rapidly enlarging tongue lesion that was diagnosed as a biphasic synovial sarcoma. The mass was resected, and a radial forearm free flap was placed. The second, a 9-year-old male, presented with jaw pain and a mandibular mass. Biopsy confirmed a diagnosis of Ewing sarcoma. The patient was treated initially with chemotherapy, followed by surgical resection and placement of an osteocutaneous fibular free flap. Both patients are disease-free 5 years post-operation.
Conclusions:
In each patient, complete resection of the primary tumor was performed eliminating the need for radiotherapy with utilization of free flap reconstruction. As advances in medicine enable better evaluation of clear margins resulting in larger resection defects, free tissue transfer provides a useful reconstructive option in the pediatric population.
