Management of mandibular AOT: outcomes following combined treatment protocol

This case presents an incidental finding of a rare mandibular adenomatoid odontogenic tumour (AOT) in a patient who reported to the outpatient department seeking orthodontic treatment for misaligned teeth. The patient showed facial asymmetry with a painless, expansile swelling in the anterior mandible. Radiographic examination revealed a well-defined radiolucent lesion containing an impacted canine, consistent with the follicular variant of AOT. Following diagnostic biopsy, the lesion was surgically enucleated and the impacted canine removed. Postoperatively, the patient underwent 10 daily sessions of hyperbaric oxygen therapy (HBOT) at 2.2 ATA (atmospheres absolute) for 90 min each. Follow-up evaluations at 6 months and 1 year demonstrated progressive bone healing and complete resolution of the swelling. The case highlights an atypical presentation of AOT in the mandible and demonstrates the potential benefits of HBOT as an adjunctive treatment to enhance tissue healing following surgical management of benign odontogenic tumours.
