Typical protocol

2.4 ATA × 90 min, Daily, 5×/week, 30–60 sessions · Marx protocol / UHMS

The evidence (2)

1. [1] Hyperbaric oxygen treatment of chronic refractory radiation proctitis

   POSITIVE

   Clarke RE, Tenorio LM, Hussey JR, et al. · International Journal of Radiation Oncology Biology Physics · 2008 · n=120 · PMID 18342453

   Double-blind randomized trial showing HBOT significantly improved healing responses in chronic refractory radiation proctitis versus sham.

   Quality: Sham-controlled RCT in radiation tissue injury.

2. [2] A new concept in the treatment of osteoradionecrosis

   POSITIVE

   Marx RE · Journal of Oral and Maxillofacial Surgery · 1985 · n=268 · PMID 6572704

   Established the protocol combining HBOT with surgery for osteoradionecrosis of the jaw, demonstrating markedly improved resolution versus antibiotics alone and defining the modern staged approach.

   Quality: Foundational clinical work; the basis of the "Marx protocol" still used today.
