Osteoradionecrosis of the mandible, a severe complication of head and neck radiation, can be treated with hyperbaric oxygen therapy. This therapy aids healing by improving oxygen delivery to damaged tissues.

Area of Science:

  • Oncology
  • Oral and Maxillofacial Surgery
  • Hyperbaric Medicine

Background:

  • Osteoradionecrosis (ORN) of the mandible is a serious complication following radiation therapy for head and neck cancers.
  • Radiation-induced vascular damage leads to tissue hypoxia, necrosis, and impaired healing.

Purpose of the Study:

  • To review the role of hyperbaric oxygen (HBO) therapy in managing osteoradionecrosis of the mandible.
  • To discuss the historical context, physiological mechanisms, and clinical applications of HBO therapy for ORN.

Main Methods:

  • Literature review of historical and current research on hyperbaric oxygen therapy for osteoradionecrosis.
  • Analysis of physiological mechanisms underlying HBO's efficacy in promoting tissue healing.
  • Examination of clinical data regarding HBO treatment protocols, outcomes, complications, and contraindications.

Main Results:

  • Hyperbaric oxygen therapy is an established treatment modality for ORN, improving tissue oxygenation and promoting angiogenesis.
  • HBO therapy facilitates healing in radiation-damaged mandibular bone by combating hypoxia and stimulating cellular activity.
  • Understanding the mechanisms and appropriate application of HBO is crucial for successful ORN management.

Conclusions:

  • Hyperbaric oxygen therapy is a valuable treatment for mandibular osteoradionecrosis, addressing the underlying hypoxia and promoting tissue repair.
  • The review highlights the importance of HBO in the multidisciplinary management of head and neck cancer survivors experiencing ORN.
  • Further research into optimizing HBO protocols and understanding its long-term effects in ORN is warranted.
