INTRODUCTION: Distraction osteogenesis is a new and reliable technique for lengthening of hard and soft tissue in cranio-maxillofacial surgery. Since its first applications, X-rays were often the preferred diagnostic method to monitor this treatment. Apart from adding an additional radiation dose, analysis cannot detect and follow the osteogenic process in the distraction gap on the one hand, nor can it evaluate the soft tissue around the distracted area. In this paper, the authors report their experience with B-scan imaging to control mandibular distraction and to overcome the shortcomings of X-rays analysis. METHOD: Comparison of B-scanning with the traditional X-ray methods was performed in 12 patients. RESULTS: B-scan evaluation appeared to be a precise technique in monitoring the different phases of distraction. It is easy to repeat whenever necessary. Early and late complications of soft tissue healing, movements of the bone segment, as well as the osteogenesis were easily detectable. CONCLUSION: In the authors' opinion B-scan evaluation can play an important role in monitoring distraction osteogenesis.

Abstract

INTRODUCTION: Distraction osteogenesis is a new and reliable technique for lengthening of hard and soft tissue in cranio-maxillofacial surgery. Since its first applications, X-rays were often the preferred diagnostic method to monitor this treatment. Apart from adding an additional radiation dose, analysis cannot detect and follow the osteogenic process in the distraction gap on the one hand, nor can it evaluate the soft tissue around the distracted area. In this paper, the authors report their experience with B-scan imaging to control mandibular distraction and to overcome the shortcomings of X-rays analysis. METHOD: Comparison of B-scanning with the traditional X-ray methods was performed in 12 patients. RESULTS: B-scan evaluation appeared to be a precise technique in monitoring the different phases of distraction. It is easy to repeat whenever necessary. Early and late complications of soft tissue healing, movements of the bone segment, as well as the osteogenesis were easily detectable. CONCLUSION: In the authors' opinion B-scan evaluation can play an important role in monitoring distraction osteogenesis.
