Reconstruction Using Transport Distraction Osteogenesis with Indigenous Distractors: A Case Series

Reconstruction of the maxilla and mandible is a complex task. The age-old options such as free bone grafts, microvascular grafts and alloplasts are associated with multiple limitations. Transport distraction osteogenesis, a relatively new mode of reconstruction, is superior to the traditional methods of reconstruction in multiple ways. It eliminates the need for a second donor site, additional soft tissue grafting, etc. In addition, it provides adequate bone height and width that allows dental rehabilitation of the patient with implants. TDO is an important tool in the armamentarium of the maxillofacial reconstruction surgeon.

We present a series of 21 cases of different types of transport distraction osteogenesis using indigenous transport distractors. Defects caused by congenital abnormalities, benign and malignant pathologies were treated. Indigenous stainless steel transport distraction devices were used to substantially reduce the costs involved in the procedure. Thirteen cases of bifocal TDO, one case of trifocal TDO and seven cases of alveolar distraction osteogenesis were done. 100% success rate was seen in this case series. Bone healing was monitored using ultrasonography to reduce radiation exposure. Bone formation was confirmed with the use of 3D CT scans.

Transport distraction osteogenesis is an effective and reliable option for the reconstruction of maxillary and mandibular defects.
