A 55 year old patient reported to our hospital with a large, bony swelling in the anterior portion of the lower jaw (mandible). He had said that the swelling had gradually increased in size over the past 1 year and there was spontaneous loss of few lower teeth over the last 6 months. He also reported of altered sensation in the lower lip for past 3 weeks which was his main concern.
A 3D CT scan was taken to gauge the extent of the lesion. A biopsy was done which showed the lesion to be a multiple cystic ameloblastoma (tumor) of the lower jaw. Maxillofacial Surgeon Dr. S. M. Balaji removed the entire bony tumor along with the involved bone and reconstructed the defective portion of mandible using the native bone itself without any bone graft by following advanced transport guided distraction osteogenesis technique.
The entire affected portion of the lower jaw was ressected with 1.5 cm marginal clearance followed by reconstruction using titanium plate guided bilateral tripod multi docking complex univector Herford plate guided mandibular transport distractor.
After 5 days of latency period, the distractors were activated at a rate of 0.5mm twice per day (on both sides) until the transport discs had reached the canine region on both sides (amount of distraction on the right side was 46mm and on the left 43.2mm). Following consolidation period of 3 months and radiological evidence of corticalization, the distractors were removed. And complete dental implant rehabilitation done for lower arch in the newly formed healthy bone. Cosmetically well blended fixed ceramic prosthesis given.
