BACKGROUND Mandibular plates may become exposed following radiation therapy, infection, and mucosal necrosis. This may lead to early removal of the mandibular plates with subsequent instability of bone fragments. OBJECTIVE To compare fibrin glue, a bioadhesive, with traditional sutures in closing mucosa over exposed mandibular plates in a cat. DESIGN Prospective matched-pairs analysis. SU...
The reconstruction of large craniofacial defects remains a significant clinical challenge. The complex geometry of facial bone and the lack of suitable donor tissue often hinders successful repair. One strategy to address both of these difficulties is the development of an in vivo bioreactor, where a tissue flap of suitable geometry can be orthotopically grown within the same patient requiring ...
BACKGROUND This study examined the usefulness of the fibula positioning guide for boosting the accuracy of mandible reconstructions. METHODS Thirty mandibular rapid prototype (RP) models were allocated to experimental (N = 15) and control (N = 15) groups. For reference, we prepared a reconstructed mandibular RP model with a three-dimensional printer, based on surgical simulation. In the exper...
OBJECTIVE Massive bone allografts are frequently used in orthopedic reconstructive surgery, but carry a high failure rate of approximately 25%. We tested whether treatment of graft with mesenchymal stem cells (MSCs) can increase the integration of massive allografts (hemi-mandible) in a large animal model. METHODS Thirty beagle dogs received surgical left-sided hemi-mandibular defects, and th...
Markedly elevated111 In labeled leukocyte activity suggestive of acute osteomyelitis was observed in a region of a composite mandibular allograft that was photon deficient on 99mTc MDP bone scintigraphy. This finding was later confirmed by surgical pathology. The patient was treated with intravenous antibiotics and returned two months later with persistent bone infection. The foHow-up thr...
Abstract Mandibular resection is a procedure to treat diseases or disorders of the mandible. Mandibulectomy indicated for involving Plate exposure common postoperative complication mandibular followed by reconstruction with plate fixation. Objective: This study was obtain data regarding number exposed cases after madibular indications ameloblastoma at KSM Oral and Maxillofacial Surgery, RSUP Dr...
PURPOSE Loss of alveolar bone in the anterior maxilla may preclude implant placement or compromise positioning and thus diminish the final esthetic result of the restoration. Bone augmentation can overcome such difficulties but may affect osseointegration. The aim of this study was to report the outcome of buccal onlay bone grafting in the anterior maxilla in routine dental implant practice. ...
The reconstruction of the mandible is a complex procedure because various cosmetic as well as functional challenges must be addressed, including mastication and oral competence. Many surgical techniques have been described to address these challenges, including non-vascularized bone grafts, vascularized bone grafts, and approaches related to tissue engineering. This review summarizes different ...
The need to cover the exposed periostium has meant that a number of materials including mucosal and skin grafts are regarded as suitable for grafting in oral and maxillofacial surgery. To circumvent the disadvantages of other materials such as skin, biological membranes have been suggested as options, including fetal membrane. The objective of the present study was to evaluate the clinical effi...
OBJECTIVE To review complications and outcomes associated with latissimus-serratus-rib free flap oromandibular and midface reconstruction. DESIGN Retrospective medical record review. SETTING Two academic tertiary care medical centers. PATIENTS Twenty-eight patients with segmental resection of the mandible and 1 patient with combined resection of the mandible and maxilla after excision of ...
