The approach of ameloblastoma of the mandible: a case treated by hyperbaric oxygen therapy and bone graft reconstruction.

BACKGROUND

Reconstruction of mandibular defects after tumor resection is a challenge to the head and neck surgeon because of associated functional and esthetic problems. The intention of mandibular reconstructive surgery is to achieve maximum possible functionality, which means the restoration of masticatory function and speech with a good esthetic result. Hyperbaric oxygen therapy (HBO) is already a well-accepted adjunct in the treatment of extensive bone defects. It has been shown to enhance osteogenesis and improve soft tissue wound healing in a variety of circumstances.

CASE REPORT

The following case report describes a 29-year-old woman who was diagnosed with mandibular ameloblastoma. The treatment of choice is resection with mandibular base maintenance. The patient underwent 10 sessions of hyperbaric oxygen therapy and subsequent nonvascularized iliac crest graft. Six months after, mandibular reconstruction is possible to observe the preservation of mandibular contouring and facial esthetics. A panoramic radiograph revealed good positioning of the bone graft and volume maintenance.

DISCUSSION

The mandibular reconstruction is extremely important for the rehabilitation of the patient who underwent bone resection. The restoration of mandibular function and facial esthetics is essential to maintain the quality of life. The use of HBO in mandibular reconstruction is an important adjunct to successful treatment, however, more studies are needed to establish the best modalities of rehabilitation.
