Optimized design for using of double-barrel vascularized fibular flap in various types of mandibular defects

Background/purpose

The functional and aesthetic reconstruction of the mandible can be achieved by using the double-barrel vascularized free fibula flap. The purpose of this study was to use multiple integrated techniques to more effectively reconstruct the mandible, some contains of our unique ideas.

Materials and methods

21 patients were included in this study. Computed tomography (CT) data of the patient's mandible and fibula were acquired preoperatively. Individualized surgical simulation was performed by using computer-aided surgical simulation (CASS) technology, about 6 kinds of integrated 3D design ideas were simultaneously perfectly transferred to real surgery. The accuracy of reconstruction was evaluated by superimposing the postoperative and preoperative image of mandible, measuring the linear and angular deviation of landmarks between the planned and actual outcomes.

Results

The mandibular reconstruction was effectively performed on all patients, and the result analysis showed that the surgical plan was precisely performed. The facial contours of the postoperative patients were harmonized and the largest mean linear and angular differences were 1.47 ± 0.31 mm and 3.97 ± 0.63°, respectively.

Conclusion

This study system illustrates how to select and position the fibula for reconstruction of various types of segmental mandibular defects by using double-barrel vascularized free fibula flap. It will provide valuable guidance and enhance the accessibility and efficiency of mandibular defects treatment.

期刊介绍： he Journal of Dental Sciences (JDS), published quarterly, is the official and open access publication of the Association for Dental Sciences of the Republic of China (ADS-ROC). The precedent journal of the JDS is the Chinese Dental Journal (CDJ) which had already been covered by MEDLINE in 1988. As the CDJ continued to prove its importance in the region, the ADS-ROC decided to move to the international community by publishing an English journal. Hence, the birth of the JDS in 2006. The JDS is indexed in the SCI Expanded since 2008. It is also indexed in Scopus, and EMCare, ScienceDirect, SIIC Data Bases. The topics covered by the JDS include all fields of basic and clinical dentistry. Some manuscripts focusing on the study of certain endemic diseases such as dental caries and periodontal diseases in particular regions of any country as well as oral pre-cancers, oral cancers, and oral submucous fibrosis related to betel nut chewing habit are also considered for publication. Besides, the JDS also publishes articles about the efficacy of a new treatment modality on oral verrucous hyperplasia or early oral squamous cell carcinoma.
