BACKGROUND: Platelet-derived growth factor alpha (PDGFRA) is a gene encoding tyrosine kinase receptor and both EGFR and PDGFRA activate tyrosine kinase. The implication of PGFRA in many cancers and its prognostic significance irrespective to EGFR status in spinal chordoma, gliomas and uterine cancers has shown a need for its investigation in oral squamous cell carcinoma (OSCC). We investigated the prognostic value of PDGFRA mRNA expression in OSCC. PATIENTS AND METHODS: The study was conducted in the department of oral maxillofacial surgery-head and neck oncology, at a tertiary hospital...

BACKGROUND: The aim of this study was to investigate the somatosensory changes at the forearm donor region after using different types of modified flap surgical techniques. METHODS: Thirty-one patients, who underwent oral and maxillofacial reconstructive surgery involving the use of a traditional radial forearm flap (TRFF) or two modified radial forearm flap techniques (MRFF-I; MRFF-II), participated in the study. Cold detection threshold (CDT), warm detection threshold (WDT), cold pain threshold (CPT), heat pain threshold (HPT), pressure pain threshold (PPT), mechanical detection threshold (MDT), and mechanical pain threshold (MPT) were assessed at four sites of the forearms corresponding to the middle of the vascular pedicle (VP) area, the middle of the forearm flap area, and the corresponding contralateral sites (cVP and cFF) at about 5...

R Ologunde, N M H McLeod
In the UK, about one person/100/year sustains a facial injury, so trauma surgery accounts for a considerable part of the caseload in oral and maxillofacial surgery (OMFS). Patient-reported outcome measures (PROM) allow for patient-centred assessment of postoperative outcomes, but to our knowledge, most research in OMFS trauma does not currently include them. To investigate their use, we searched Medline to find relevant studies that reported outcomes from inception in January 1879 to August 2016. Those not in the English language and those that did not report operations were excluded...

Osseous reconstruction of large bone defects remains a challenge in oral and maxillofacial surgery. In addition to autogenous bone grafts, which despite potential donor-site mobility still represent the gold standard in reconstructive surgery, many studies have investigated less invasive alternatives such as in vitro cultivation techniques. This study compared different types of seeding techniques on pure β-tricalcium phosphate scaffolds in terms of bone formation and ceramic resorption in vivo . Cylindrical scaffolds loaded with autologous cancellous bone, venous blood, bone marrow aspirate concentrate or extracorporeal in vitro cultivated bone marrow stromal cells were cultured in sheep on a perforator vessel of the musculus latissimus dorsi over a 6-month period...

Training in oral and maxillofacial surgery (OMFS) in the UK has undergone considerable changes during the last 10years, and "core" surgical training has replaced "basic" surgical training. In 2014 a pilot "run-through" training programme from specialist training year one (ST1)-ST7 was introduced to facilitate early entry into the speciality. Run-through training guarantees that a trainee, after a single competitive selection process and satisfactory progress, will be given training that covers the entire curriculum of the speciality, whereas uncoupled training requires a second stage of competitive recruitment after the first one (for OMFS only) or two years of "core" training to progress to higher specialty training...

An effective office emergency preparedness plan for the oral and maxillofacial surgery office can be developed through the use of well-designed checklists, cognitive aids, and regularly scheduled in situ simulations with debriefings. In order to achieve this goal, the hierarchal culture of medicine and dentistry must be overcome, and an inclusive team concept embraced by all members of the staff. Technologic advancements in office automation now make it possible to create interactive cognitive aids. These enhance office emergency training and provide a means for more rapid retrieval of essential information and guidance during both simulations and a real crisis...

The model for oral and maxillofacial surgery (OMFS) delivery of office-based, open airway anesthesia has morphed from the operator-anesthetist to the delivery of team anesthesia, supporting a widespread focus on organizational aspects of the delivery of care. The training, continuing education, and coordination of a diverse anesthesia team provides a system to improve the safety and efficacy of anesthesia delivery. The hallmarks of this system include communication, checks and balances, monitoring, team dynamics, protocols, emergency scenario preparation and rehearsal, and crisis resource management during an emergent situation...

Efficient responses to emergencies in the oral and maxillofacial surgery office require preparation, communication, and thorough documentation of the event and response. The concept of team anesthesia is showcased with these efforts. Emergency medical services training and response times vary greatly. The oral and maxillofacial surgery office should be prepared to manage the patient for at least 15 minutes after making the call to 911. Patient outcomes are optimized when providers work together to manage and transport the patient...

The complexity of the craniofacial patient mandates the cooperation of a multidisciplinary team that can systematically evaluate each individual and ensure that a protocol-driven pathway is undertaken for the best patient care. Oral and maxillofacial surgeons contribute to surgical care in this setting with specific knowledge of growth and development of the face. This enables optimum timing for early skeletal correction where appropriate, and definitive surgery following the cessation of growth to maximize function and aesthetics...

Oral and Maxillofacial Surgery developed initially from Dentistry as exodontia. It then expanded into the surgical management of jaw disorders. As the specialty evolved, it came into increasing conflict with related surgical disciplines. In the 1960s and 1970s these external criticisms were well-founded as training in oral surgery was individual, solely University-based and highly variable. In the 1980s the speciality developed a plan which involved hospital-based surgical training, a mandatory high level college surgical examination and detailed workforce and training studies...
