Mandibular defects usually involve a combination of osseous and soft tissue deficiency and are among the most challenging problems in maxillofacial surgery, many options are available for mandibular reconstruction. One of the options discussed in literature recently being distraction osteogenesis.
The aims and objectives of the study were to evaluate clinically the technique of distraction osteogenesis to reconstruct mandibular defects, using indigenous transport distractors, and to evaluate the efficacy of Indigenous transport distraction osteogenesis device.
A prospective, experimental study was designed to examine the use of transport distraction osteogenesis in the treatment of defects of the mandible. Four patients with defects of the mandible were subjected to distraction osteogenesis with indigenously manufactured distraction device. The regenerate was assessed clinically and radiographically.
The results showed that the regenerate was clinically as hard as the adjacent unaffected mandible and radiologic evidence of bone regeneration was observed. The major advantage being regeneration of hard tissue and soft tissue components without the morbidity of donor site, so that functional rehabilitation of the patient is possible.
Thus from our study it is shown that transport distraction osteogenesis using indigenous distractors is a reliable yet affordable option for reconstruction of mandibular defects.
下颌骨缺损通常涉及骨组织和软组织的联合缺失,是颌面外科中最具挑战性的问题之一,下颌骨重建有多种选择。文献中最近讨论的选择之一是牵张成骨术。
本研究的目的是临床评估使用国产运输式牵张器进行牵张成骨术重建下颌骨缺损的技术,并评估国产运输式牵张成骨装置的疗效。
设计一项前瞻性实验研究,以检查运输式牵张成骨术在下颌骨缺损治疗中的应用。4名下颌骨缺损患者使用国产牵张装置进行牵张成骨术。对再生骨进行临床和影像学评估。
结果显示,再生骨在临床上与相邻未受影响的下颌骨一样坚硬,并且观察到骨再生的影像学证据。主要优点是硬组织和软组织成分再生,而无供区并发症,从而使患者能够进行功能康复。
因此,我们的研究表明,使用国产牵张器的运输式牵张成骨术是重建下颌骨缺损的一种可靠且经济的选择。
