There is minimal information regarding free tissue transfers in very young infants, especially those less than a year old. It is often thought that that age remains a limit to free tissue transfers, with younger patients having smaller vessels, making the operation technically challenging. In this case report, we discuss the youngest and smallest recorded case of a free flap reconstruction. A 3-month-old patient with a malignant parapharyngeal undifferentiated round cell sarcoma underwent a resection and reconstruction with a radial forearm free flap (RFFF). The defect was 35 by 20 by 15 mm, and required a pharyngeal "patch," as opposed to a "tube," reconstruction. The defect was templated, and the RFFF then raised in a standard subfascial fashion, and inset with resorbable sutures. The patient was observed in the ICU postoperatively. The patient was subsequently diagnosed with Stage IV primary undifferentiated sarcoma with regional metastasis and received adjuvant chemotherapy. Fifteen-month follow up revealed no signs of recurrence, full oral intake, a well-reconstructed pharynx on nasoendoscopic examination, and minimal donor site morbidity. This report illustrates several unique adaptations of free flap transfer in infants and adds to the emerging body of evidence that age is not a contraindication for head and neck reconstruction.
