Fostering a faster post-operative wound healing process with hyperbaric oxygen therapy in a rare case of squamous odontogenic tumor

Abstract

INTRODUCTION: The surgical removal of an intraoral tumor and preventing intraoral wound dehiscence are constant challenges faced by surgeons today. Hyperbaric oxygen therapy (HBOT), the inhalation of 100% oxygen at a greater atmospheric pressure, is often used in cases of wounds to induce a faster wound healing process, alongside other treatment modalities. We report a rare case of squamous odontogenic tumor (SOT) treated with HBOT after being surgically removed to foster an accelerated wound recovery. CASE PRESENTATION: A 39-year-old Asian male presented with an intraoral 3 × 4 cm tumor, accompanied by acute pain on the maxillary region. Biopsy results showed a solid, brown parenchyma with islands of mature squamous epithelial cells, confirming the diagnosis of an SOT. An intraoral surgical approach was performed to remove the tumor. The patient was then treated with prophylactic antibiotics and 5 consecutive, daily sessions of HBOT at 2.0 ATA as an adjuvant therapy. No further complaints and no abnormalities were found at the 2-week follow-up evaluation. DISCUSSION: In our case of SOT, HBOT plays a role to inhibiting the bacterial growth which could lead to post-operative wound infections. A number of studies have incorporated HBOT as an adjuvant therapy for post-operative intra oral wounds which has resulted in minimal wound complications. CONCLUSION: The use of HBOT as an adjunctive therapy in managing possible wound complications after the resection of an intraoral tumor enables a faster angiogenesis process, reduces tissue hypoxia and minimizes the risk of post-operative wound infections; hence fostering the wound healing process.
