After a Lefort surgery, why is hyperbaric oxygen (HBO) treatment indicated?

• A. To reduce pain during recovery
• B. To hasten delineation and prevent ischemic injury
• C. To improve general healing
• D. To aid in anesthesia

Answer: (B)

The indication for hyperbaric oxygen (HBO) treatment following Lefort surgery primarily relates to its ability to enhance tissue oxygenation, which is crucial in the prevention of ischemic injury. After surgical procedures like Lefort osteotomies, which involve significant manipulation of facial structures, there is a potential risk of compromised blood supply to the affected areas. Ischemic tissue can lead to delayed healing or necrosis due to insufficient oxygen.

HBO therapy provides a high-pressure environment that increases the amount of dissolved oxygen in the plasma. This elevated oxygen saturation facilitates better oxygen delivery to the ischemic tissues, promoting angiogenesis and improving overall vascular function. This is particularly important in complex surgical sites where blood supply may be disrupted. Consequently, the use of HBO is beneficial in these scenarios to accelerate healing and prevent complications associated with ischemia, thereby validating the selection of this option as the correct rationale for its use following Lefort surgery.
