Plate-related complications after mandibular reconstruction: observational study osteotomy

Abstract

Background: Mandibular reconstruction following bony resection is crucial in cases of oral and mandibular tumors. Complications such as infection, plate exposure, or plate fracture can occur because of some risk factors after these reconstructive surgeries. Objectives: The purpose of this study were to report some of the postoperative complications of reconstruction plates, and to analyze the risk factors associated with those complications. Patients and methods:We analyzed clinical and radiological data of 19 patients who required mandibular reconstructive surgery. The complications related to plates were recorded and used as an objective measure of outcome. Results: Plate-related complications developed in 8/19 patients. The complications involved screw loosening (n=2), plate fracture (n=2), plate exposure (n=3), and heat sensitivity (n=1). No significant differences were found in plate survival rate in relation to age or sex. Moreover, complications associated with plates developed in 73.68% of the patients with defect in the mandibular body crossing the midline of the mandible. Radiotherapy decreased the survival rate of the plates, as 60% of the irradiated patients had a higher risk of plate-related complications. and angle area and 100% of the patients who had defect crossing the midline of the mandible. Radiotherapy decreased the survival rate of the plates, as 60% of the irradiated patients had a higher risk of plate-related complications. Conclusion: The survival rate of mandibular reconstruction plate relies on mechanical and biological risk factors in terms of site of mandibular defects and radiation therapy, respectively.

Intensive Care as an Independent Risk Factor for Infection after Reconstruction and Augmentation with Autologous Bone Grafts in Craniomaxillofacial Surgery: A Retrospective Cohort Study

“…With this study, possible risk factors could be identified showing a significant correlation with the occurrence of complications in general, and especially with infections and infections with problematic germs. The complication rate of 25.8% in the cohort is in the lower to medium range of the 10.3 to 69.2% reported as having a high variability by comparable studies [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Regarding our complication rate, the fact should be considered that we have only recorded complications that required a surgical revision procedure after bone reconstruction and augmentation on the recipient side, and that we did not assess donor site morbidity including wound healing complications such as those observed rather frequently after skin-split grafts at the donor site.…”

“…The choice of graft depends on the anatomical location and size of the defect, with fibula grafts being the most used as the current "gold standard" [1,2]. The complication rate for reconstruction and augmentation procedures using autologous bone grafts in craniofacial surgery is reported with a greatly varying range between 10.3 to 69.2% [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18], a re-operation rate of 10.6 to 58.2% [11,[18][19][20][21] and a graft failure rate of 1.3 to 27% [3,[9][10][11]13,[20][21][22]. The correlation between graft failure and complication rate is controversially discussed with the type of graft used [2,20,23].…”

Treatment of extended comminuted mandibular fractures with infected cutaneous fistule Post-ORIF using a reconstruction plate: A case report

“…The efficacy of mandibular reconstruction has improved greatly in recent years due to the use of titanium reconstruction plates that provide better biocompatibility and locking screws for biomechanical enhancement. These improvements effectively provide rigid fixation needed for proper bone healing [ 14 ]. A 10-year review by Ellis et al found that in cases of comminuted mandibular fractures, ORIF with a bone reconstruction plate had low complication rates [ 6 ].…”

In Silico Investigation of Mandibular Reconstruction: Tissue Differentiation Dynamics with Particulate-Cancellous Bone Marrow Grafts under Varied Bite Forces and Implant Elastic Moduli

“…This bone graft is commonly harvested from the iliac or tibia, processed in a particulate form, and inserted into the body using an implant, typically made from titanium. However, serious problems such as implant fractures during the healing phase are still encountered (Martola et al, 2007;Radwan & Mobarak, 2018;Seol et al, 2014;Yamada et al, 2016). Almansoori et al (2020) reported that implant fractures were observed in 13.84% of mandibular reconstruction cases.…”
