Comparison of safety outcomes between bi-coronal and direct approaches for device removal in patients treated with distraction osteogenesis for craniosynostosis

Distraction osteogenesis (DO) is a surgical technique used in the treatment of facial deformities and malformations and also in the treatment of alveolar bone deficiencies. The aim of this paper is to show the case of a patient with partial edentulism in the symphysis area with a severe vertical and horizontal bone deficiency caused by mandibular trauma. At the initial analysis, the patient related a recent history of fracture in symphysis and right angle of the mandible. Treatment had not been entirely succesfull, therefore, after studying the options, we opted for a treatment at different stages: Stage 1, surgery for osteo shynthesis removal, soft tissue preparation and replacement of the posterior margin of mandibular symphysis; stage 2, distraction osteogenesis, performed 3 months after the first intervention and stage 3, distractor device removal and dental implant installation, performed 6 months after the second intervention. We discuss some factors involved in the treatment success.

Correct Structure

Purpose Craniofacial anomalies (CFA) often result in growth abnormalities of the facial skeleton adversely affecting function and appearance. The functional problems caused by the structural anomalies include upper airway obstruction, speech abnormalities, feeding difficulty, hearing deficits, dental/occlusal defects, and cognitive and psychosocial impairment. Managing disorders of the craniofacial skeleton has been improved by the technique known as distraction osteogenesis (DO). In DO, new bone growth is stimulated allowing bones to be lengthened without need for bone graft. The purpose of this clinical focus article is to describe the technique and clinical applications and outcomes of DO in CFA. Conclusion Distraction can be applied to various regions of the craniofacial skeleton to correct structure and function. The benefits of this procedure include improved airway, feeding, occlusion, speech, and appearance, resulting in a better quality of life for patients with CFA.
