Hyperbaric oxygen therapy treatment as an alternative for a chronic sinus tract after chordoma surgery and radiation.

Chordoma is a rare form of cancer that forms from the notochord remnants, and affects the skull and the spine. The standard treatment for a sacrococcygeal chordoma is surgery and radiation. Chordoma has a high rate of recurrence and surgery with radiation treatment can leave patients with surgical site complications, such as wounds, fistulas or sinus tracts.
