This protocol describes the use of a newly developed external fixator for distraction osteogenesis in a rat femoral model. Distraction osteogenesis (DO) is a surgical technique leading to bone regeneration after an osteotomy. The osteotomized extremities are moved away from each other by gradual distraction to reach the desired elongation. This procedure is widely used in humans for lower and upper limb lengthening, treatment after a bone nonunion, or the regeneration of a bone defect following surgery for bone tumor excision, as well as in maxillofacial reconstruction...

OBJECTIVE: Postoperative pneumonia (POP) is common and results in prolonged hospital stays, higher costs, increased morbidity and mortality. However, data on the incidence and risk factors of POP after oral and maxillofacial surgery are rare. This study aims to identify perioperative risk factors for POP after major oral cancer (OC) surgery. METHODS: Perioperative data and patient records of 331 consecutive subjects were analyzed in the period of April 2014 to March 2016...

Regular monitoring of free flaps is essential after microvascular free tissue transfer, but the frequency and duration of the observations vary between units and there is no consensus nationally. Best practice can be informed by the feedback of patients, but as we know of no such studies, we did a cross-sectional survey of a consecutive group of patients after free tissue transfer to find out what they thought about monitoring. We designed a study-specific questionnaire after consultation with the patient and carer forum, and sent it to 150 patients who had had free tissue transfer in the maxillofacial department at Aintree University Hospital during 2015 and 2016...

Total mandibular reconstruction is one of the most challenging modalities in maxillofacial surgery. In this article, we try to introduce a method of total mandible reconstruction. We report a 25-year-old male patient with complete involvement of the mandible by Langerhans cell tumor. The patient underwent total mandibulectomy and reconstruction with bone allograft harvested from a donor who had died the day before. The patient has good functional and aesthetic results in a long time. It seems that bone allograft can be a good alternative to other methods in total mandibular reconstruction...

Autogenous bone grafts are the gold standard for reconstruction of atrophic jaws, pseudoarthroses, alveolar clefts, orthognathic surgery, mandibular discontinuity, and augmentation of sinus maxillary. Bone graft can be harvested from iliac bone, calvarium, tibial bone, rib, and intraoral bone. Proximal tibia is a common donor site with few reported problems compared with other sites. The aim of this study was to evaluate the use of proximal tibia as a donor area for maxillofacial reconstructions, focusing on quantifying the volume of cancellous graft harvested by a lateral approach and to assess the complications of this technique...

The zygomatico-orbital artery is the largest artery in the temporal area. With the increasing number of reconstructive and aesthetic surgeries in the area, in-depth understanding of this artery is needed. Thus, the aim of this anatomical study was to determine more information on the zygomatico-orbital artery using contrast-enhanced three-dimensional computer tomography (CT) and color-flow Doppler sonography. On the basis of CT images taken between October 2015 and October 2016 for diagnosing and treating maxillofacial conditions, 50 patients were selected...

PURPOSE: Combined ablative and reconstructive oral maxillofacial surgery involves a multitude of anatomical and functional structures for speech and swallowing. Although there are a few methods to objectively examine swallowing function, this is not true for speech. We describe the development of an objective visualization and measurement tool for magnetic resonance imaging (MRI) to evaluate speech and its first application in a patient. MATERIAL AND METHODS: A total of 20 healthy patients and one patient with squamous cell carcinoma localized in the anterior floor of the mouth were included in the study...

Although a silicone facial prosthesis has many advantages, silicone's limited cementation with resin or metal has caused many maxillofacial reconstructive surgeons and prosthodontists concern regarding the use of silicone-based facial prostheses. This study demonstrates 1 representative silicone facial prosthesis patient with magnet cementation to silicone using plastic clay, which will be applied to various maxillofacial prosthesis strategies in the near future.

Microsurgical free flaps have become the first choice for reconstruction of oral and maxillofacial (OMF) defects after tumor resection. Till recently the pectoralis major myocutaneous flap (PMMC) was considered to be the benchmark for OMF reconstruction. This philosophy is changing fast with rapid advancement in reconstructive microsurgery. Years of innovation in reconstructive microsurgery has given us a reasonably good number of excellent flaps. Tremendous work has been put into producing some exceptionally brilliant research articles, sometimes contradicting each other...

Adam P Fagin, Daniel Petrisor
The effectiveness and reliability of microvascular reconstruction for large defects in the head and neck is no longer disputed. However, many controversies still persist in the ideal perioperative management of patients undergoing free tissue transfer. The optimal method of postoperative monitoring, the use of vasoconstrictors in the perioperative period, and the use of anticoagulants in the postoperative period remain topics of debate. This article offers recommendations on each of these controversies based on a review of the current literature...

Traditional reconstruction of the head and neck and significantly evolved over the last 20 to 30 years with advances in microvascular surgery, biologic materials such as bone morphogenic protein, and dental implant predictability. Earlier and more definitive reconstruction can now be achieved with combining therapies, allowing patients immediate restoration of function and improved cosmetics. Antiresorptive medications, such as Denosumab and bisphosphonates, have complicated bony reconstruction treatments with altered biology and less-predictable results...

INTRODUCTION: The specialty of periodontology has changed dramatically in recent years. With the long-standing goal of retaining teeth in a functional and esthetical state, the periodontology has developed a high level of expertise in the regeneration of bone and connective tissues that support the teeth. However, periodontists have also joined maxillofacial surgeons as the primary providers of implant surgery. METHODS: The tremendous innovations of periodontists induced also by the marketplace resulted in predictable periodontal treatment outcomes for most patients by the implants led to a dramatically different marketplace in which many patients with periodontitis can be treated by the implants rather than the traditional periodontal treatment...

Computer-aided design/computer-aided manufacturing (CAD/CAM) guides are now widely used in maxillofacial reconstruction. However, there are few reports of CAD/CAM guides being used for scapular flaps. The authors performed the secondary maxillary and orbital floor reconstruction using a free latissimus dorsi muscle, cutaneous tissue, and scapular flap designed using CAD/CAM techniques in a 72-year-old man who had undergone partial maxillectomy four years previously. The patient had diplopia, the vertical dystopia of eye position, and a large oral-nasal-cutaneous fistula...
