Analysis of simulated mandibular reconstruction using a segmental mirroring technique.

J Craniomaxillofac Surg 2019 Mar 30;47(3):468-472. Epub 2018 Dec 30.

Department of Otolaryngology, Head & Neck Surgery/Surgical Oncology, Princess Margaret Cancer Centre and Guided Therapeutics (GTx) Program, University of Toronto, Toronto, Ontario, Canada. Electronic address:

Purpose: When deforming pathology limits intraoperative plating of the mandible, three-dimensional (3D) models can be generated by digitally replacing the deformed segment of bone with an inverted segment from the contralateral unaffected mandible to adapt a reconstruction plate. The purpose of this study was to use 3D conformance analysis to evaluate the degree of accuracy of this "segmental mirroring" technique.

Methods: Using a pre-existing melanoma database (January 1, 2005-September 20, 2015), high-resolution computed tomography (CT) scans of the head and neck were obtained from patients without evidence of bony disease or defects involving the mandible. Read More

Modern concepts in mandibular reconstruction in oral and oropharyngeal cancer.

Curr Opin Otolaryngol Head Neck Surg 2011 Apr;19(2):119-24

Mayo Clinic, Phoenix, Arizona, USA.

Purpose Of Review: This article reviews literature pertaining to advances in oromandibular reconstruction in the context of a 30-year background of microvascular free tissue transfer, which still represents the current standard of care.

Recent Findings: Most literature reiterates established patterns of reconstruction. Notable exceptions address these key areas: the use of computer-assisted modeling to more closely and efficiently design the excision of the mandible, to produce the template and to contour the fibula bone to fit the defect; the evolution of plating techniques to maximize the bony repair; distraction osteogenesis; tissue engineering; and optimal techniques for dealing with osteonecrosis, from both radiation and bisphosphonate use.

Nonunion of mandibular midline osteotomy after tumor surgery and radiation repaired by endosseous implants.

J Oral Maxillofac Surg 2010 Apr 30;68(4):833-6. Epub 2009 Dec 30.

Oral and Maxillofacial Surgery Department, Thomas Jefferson University Hospital, Philadelphia, PA 19107, USA.

Nonunion of the mandible after microvascular flap reconstruction of defects resulting from tumor surgery is a known but rare complication, occurring in 5% of cases. When nonunion results with the use of microvascular flaps, rigid internal fixation, and radiotherapy, other options to treat the nonunion carry a greater risk of osteomyelitis, osteoradionecrosis, and/or persistent nonunion. Although endosseous implants have been reported to cause mandibular fracture in some cases, our case proposes and supports the use of implants for immobilization and/or prevention of nonunion of the mandible in patients who have a high probability of this complication developing, thereby avoiding plating across the nonunion site with the risk of plate exposure and osteoradionecrosis.

Torsional strength of the radius after osteofasciocutaneous free flap harvest with and without primary bone plating.

Otolaryngol Head Neck Surg 2000 Oct;123(4):400-8

Department of Otolaryngology-Head and Neck Surgery, University of Kansas School of Medicine, Kansas City 66160-7380, USA.

The osteocutaneous radial forearm free flap (OCRFFF) has not gained widespread popularity in mandibular reconstruction, primarily because of concerns about pathologic fracture of the weakened radius. This study examines the effectiveness of plate fixation of the radius bone after harvest of the OCRFFF as a mechanism to minimize donor-site morbidity and increase the usefulness of the OCRFFF. Matched pairs of fresh human cadaveric radius bones were used in this study. Read More

[The development of modern osteosynthesis].

Authors:
H G Luhr

Mund Kiefer Gesichtschir 2000 May;4 Suppl 1:S84-90

Kieferchirurgische Abteilung, Universität Göttingen.

Within the last 30 years, rigid fixation has revolutionized a wide range of treatment procedures in cranio-maxillofacial surgery. Rigid fixation allows for a three-dimensional reconstruction of the facial skeleton. In fracture treatment and following osteotomies in orthognathic surgery, any postoperative maxillo-mandibular fixation by dental arch bars can be avoided. Read More

Monitoring of graft perfusion and osteoblast activity in revascularised fibula segments using [18F]-positron emission tomography.

Int J Oral Maxillofac Surg 1999 Oct;28(5):349-55

Department of Oral and Maxillofacial Surgery, University Medical School, Hannover, Germany.

The aim of the present study was to evaluate healing of revascularised fibula grafts used for mandibular reconstruction using [18F]fluoride ion and positron emission tomography (PET). Sixteen PET studies in 11 fibula grafts were analysed to determine both blood flow and fluoride influx as a measure of vascularisation and osteogenic activity. Two graft failures and three non-unions were encountered and were compared to the successfully healed grafts. Read More

Assessment of plate use for mandibular reconstruction: has changing technology made a difference?

Otolaryngol Head Neck Surg 1999 Oct;121(4):388-92

Division of Otolaryngology, Department of Surgery, University of South Florida, Tampa 33606, USA.

Reconstruction of mandibular defects with a variety of alloplastic materials during a 22-year period was reviewed. Outcomes were examined to determine whether specific plating technology affected the incidence of plate-related complications including plate exposure, plate fracture, and plate removal. Repair with the miniplate, reconstruction plate, titanium hollow screw reconstruction plate, and locking reconstruction plate was evaluated. Read More

Comparison of fixation strengths of locking head and conventional screws, in fracture and reconstruction models.

J Oral Maxillofac Surg 1998 Apr;56(4):468-73

Department of Surgery, Louisiana State University Medical Center at Shreveport, 71130, USA.

Purpose: Claimed clinical advantages of the locking-head mandibular reconstruction plating system include the ability to achieve stability with fewer numbers of screws per bony segment as compared with conventional screws. The purpose of this study was to test the hypothesis that increased resistance to displacement will be obtained when using locking-head as compared with the same number of conventional screws per segment in both fracture and reconstruction models.

Materials And Methods: Eight groups were tested based on the screw number (two or four), screw type (locking-head or conventional), and fracture (bony apposition) or reconstruction model (1-cm defect). Read More

Fixation with reconstruction plates under critical conditions: the role of screw characteristics.

Int J Oral Maxillofac Surg 1996 Dec;25(6):469-73

Department of Oral and Maxillofacial Surgery, Helsinki University Central Hospital, Finland.

Mandibular angular ostectomy defects in 12 sheep were bridged with a titanium plate system (THORP), designed according to the screw-plate-locking principle. Two screw designs (hollow and solid) and two rough (plasma-coated, sand-blasted)-surface and one smooth (anodized)-surface structure were tested in a critical two-screw anchorage model. Fixation with two screws only per fragment was successful in only one-third of the cases. Read More

Section of Pediatric Otolaryngology, Albany Medical College, New York, USA.

In today's fast-paced society, many children sustain severe maxillofacial injuries that require surgical reconstruction. The factor that differentiates the treatment of pediatric facial fractures from those of adults is facial growth. Anticipation of mandibular growth facilitates repair because most injuries can be treated with intermaxillary fixation. Read More

Use of reconstruction plates in conjunction with soft-tissue free flaps for oromandibular reconstruction.

Authors:
J B Boyd

Clin Plast Surg 1994 Jan;21(1):69-77

Department of Surgery, University of Toronto, Ontario, Canada.

The plate-flap option has a place in oromandibular reconstruction: It allows an expedient method to obtain an excellent cosmetic and functional result with minimal donor site disability. It is best for lateral and posterior low-volume defects in the debilitated, the elderly, and in those patients with a poor prognosis. This technique may be used as a preliminary to vascularized bone grafts in patients receiving postoperative radiotherapy. Read More

Biomechanics of the facial skeleton.

Clin Plast Surg 1992 Jan;19(1):11-29

Department of Civil Engineering, Case Western Reserve University, Cleveland, Ohio.

Several concepts have been discussed in this article. (1) The geometry and muscle attachments of the mandible are such that it is inconsistent with physics as we know today to have this structural arrangement always in tension at the upper surface and compression always at the lower. (2) The idea behind rigid internal fixation (RIF) is to stabilize the fracture to allow the mandible to work (function) as a nonfractured structure. Read More

Mandible reconstruction with vascularized bone grafts. A histologic evaluation.

Arch Otolaryngol Head Neck Surg 1991 Aug;117(8):917-25

Department of Surgery, University of California, San Diego, Medical Center.

To our knowledge, a histologic evaluation of bone healing after mandible reconstruction with vascularized human bone grafts has not been previously reported. Serial sections through both the decalcified graft and the junction between mandible and graft were evaluated in four patients who required surgical removal of their reconstructed mandibles. A failed scapular bone graft that had been wrapped within a pectoralis major myocutaneous flap for salvage following pedicle thrombosis showed markedly resorbed but viable bone with a fibrous union to the native mandible.
