Modified folding radial forearm flap in soft palate and tonsillar fossa reconstruction.

Wide excision of cancer arising from the tonsillar fossa and soft palate has several functional sequelae (e.g., speech, swallowing, chewing, and breathing) that require surgical restoration of the pharyngeo-palatal structure and optimal velopharyngeal function. For this purpose, several kinds of surgical procedures have been introduced. Our method to reconstruct the tonsillar fossa and soft palate entails folding the flaps and reconstructions at the same time as the oral and nasal planes, with some modifications.Patient 1 was a 64-year-old man with left soft palate cancer. After wide excision of the tumor, the defect size of the nasal floor was 3 × 3 cm, and that of soft palate and tonsillar fossa was 8 × 5 cm. Patient 2 was a 49-year-old man with left tonsil cancer. The defect size of the nasal floor was 3 × 3 cm, and that of left lateral wall of the tonsillar fossa was 8 × 3 cm. For reconstruction of oral, nasal, and tonsillar plane, we designed the flap fit to the defect site, especially cutting of the edge of the square plane of the flap to a round shape.Both patients achieved good functional recovery without surgical complications. The average speech intelligibility score in the 2 patients was 10. Swallowing functional score was 4 in both patients. Creative reconstruction with modified radial forearm free flap for tonsillar and soft palate area makes it possible to restore velopharyngeal function to levels close to the preoperative condition.
