Fibula Flaps for Mandibular and Maxillary Reconstruction

Check if the same lab product or an alternative is used in the 5 most similar protocols

From March 2015 to December 2021, a total of 118 consecutive patients who undergoing free fibula flaps for mandible or maxillary reconstructions at the Department of Oral and Maxillofacial Surgery, Stomatological Hospital affiliated to Nanjing Medical University was retrospectively reviewed. All cases were clinically examined to confirm the primary lesions. Exclusion criteria were as follows: patients were less than 18 years old; patients with bone metabolic disease, such as hyperparathyroidism and diabetic mellitus. Due to the availability of mandibular data, this study also included 4 cases of fibula-based maxillary reconstruction.
All patients were received preoperative CBCT (NewTom VGi, Verona, Italy) scans for mandibular evaluation and CT-angiographical (CTA) examination of the bilateral lower legs, respectively. The CBCT images were acquired at 80 kV and 10 mA, with scanning layer thickness of 0.25 mm. The CTA acquisition parameters were 120 kV and 150 mA, with a tube rotation speed of 0.3 s, in a 256 slice multi-slice computed tomography (MSCT) by Brilliance iCT (Philips Healthcare, Netherlands) in the Department of Radiology, Chinese Traditional Hospital of Jiangsu Province. The digital imaging and communication in medicine (DICOM) data of CBCT and CTA was imported into a three-dimensional reconstruction software Proplan (Proplan, Materialise, Belgium).

3D-Guided Mandibular Reconstruction with Fibula Flaps

Check if the same lab product or an alternative is used in the 5 most similar protocols

For all patients, CT scans of the craniofacial skeleton and fibula (with concomitant CT angiography) were obtained preoperatively. The scans were imported into a three-dimensional (3D) software program (Proplan, Materialise, Leuven, Belgium). The medical imaging engineer at our institution performed the virtual planning. Upon determination of appropriate margins, a virtual resection was completed, followed by evaluation of fibular segment lengths (SLs) and number of osteotomies. Based on these data, 3-matic software (Materialise, Leuven, Belgium) was used to design a reconstructed mandibular model, fixation tray, and cutting guides for mandibular and fibular osteotomies, which were printed using a Connex 350 3D printer (Stratasys, Eden Prairie, MN, USA) (Fig. 1). For each patient, the reconstruction plate was manually bent based on the 3D-printed reconstructed mandible model, which included the reconstruction with one or more fibular segments. Surgeon preference determined the type of fixation plate used for the reconstruction. We used 2.3 mm (n = 11) and 2.7 mm (n = 15) locking reconstruction plates with monocortical locking screws (KLS Martin Group, Tuttlingen, Germany). A fixation tray was used for guided placement of the reconstruction plate.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
