Comparative Study of MSCA-1 and CD146 Isolated Periosteal Cell Subpopulations.

Cell Physiol Biochem 2018 12;51(3):1193-1206. Epub 2018 Dec 12.

Department of Oral and Maxillofacial Surgery of the University Hospital of Tübingen, Tübingen,

Background/aims: Periosteal tissue is a valuable source of multipotent stem cells for bone tissue engineering. To characterize these cells in detail, we generated an immortalized human cranial periosteal cell line and observed an increased MSCA-1 and CD146 expression, as well as an earlier and stronger mineralization compared to the parental cells. Further, we detected a higher osteogenic potential of MSCA-1high compared to MSCA-1low cranial periosteal cell (CPC) fractions. Read More

Re-exposure in cone beam computed tomography of the dentomaxillofacial region: a retrospective study.

Dentomaxillofac Radiol 2018 Dec 12:20180184. Epub 2018 Dec 12.

1 Department of Oral and Maxillofacial Surgery, Plastic Surgery, University Medical Center of the Johannes Gutenberg-University Mainz , Mainz , Germany.

Objective:: CBCT often use a smaller field of view compared to conventional CT scans. This might lead to a wrong field of view with the need for secondary exposure ("retakes"). The purpose of this retrospective study was to assess the frequency of re-exposures in cone beam computed tomography (CBCT) and to identify whether the parameters age, gender and FOV have an influence on the re-exposure of the patient.

An integrated method for understanding the function of macro-lithic tools. Use wear, 3D and spatial analyses of an Early Upper Palaeolithic assemblage from North Eastern Italy.

PLoS One 2018 12;13(12):e0207773. Epub 2018 Dec 12.

Department of Oral and Maxillofacial Sciences, Diet and Ancient Technology Laboratory (DANTE), Sapienza University, Rome, Lazio, Italy.

The article presents an original analysis which combines use-wear, 3D modelling and spatial analyses to experimental archaeology in order to investigate Early Upper Palaeolithic flint-knapping gestures and techniques involving the use of macro-lithic tools. In particular, the methodological framework proposed in this paper was applied to the study of Protoaurignacian and Aurignacian macro-tools from Fumane Cave (Verona, Italy). Combining spatial analysis and use wear investigation, both at low and high magnifications, permitted the identification and detailed description of the use-related traces affecting both the hammerstones and retouchers which, at Fumane Cave, were used at different stages during flint tool production.

Mandibular reconstruction with a ready-made type and a custom-made type titanium mesh after mandibular resection in patients with oral cancer.

Maxillofac Plast Reconstr Surg 2018 Dec 25;40(1):35. Epub 2018 Nov 25.

Department of Oral and Maxillofacial Surgery, School of Dentistry, Pusan National University, 20, Geumo-ro, Mulgeum-eup, Yangsan, Gyeongsangnam-do South Korea.

Background: After the resection at the mandibular site involving oral cancer, free vascularized fibular graft, a type of vascularized autograft, is often used for the mandibular reconstruction. Titanium mesh (T-mesh) and particulate cancellous bone and marrow (PCBM), however, a type of non-vascularized autograft, can also be used for the reconstruction. With the T-mesh applied even in the chin and angle areas, an aesthetic contour with adequate strength and stable fixation can be achieved, and the pores of the mesh will allow the rapid revascularization of the bone graft site.

First two cases of craniomaxillofacial fibrous dysplasia from Nepal - case series.

Clin Cosmet Investig Dent 2018 26;10:269-274. Epub 2018 Nov 26.

Department of Oral and Maxillofacial Surgery, Chitwan Medical College and Teaching Hospital, Bharatpur-10, Chitwan, Nepal.

Fibrous dysplasia is a benign fibro-osseous disease of the bone, which is most commonly associated with congenital mutations in cAMP regulating protein Gsα coded by gene. Often it is seen involving the craniofacial skeleton and can range from an asymptomatic monostotic form to polyostotic variant involving almost all the bones of the skull, thereby leading to functional and esthetic problems. This requires a continuous monitoring of the involved region throughout the life of the patient, even after the surgical interventions. Read More

Epithelioid cell granuloma with caseating necrosis possibly caused by periapical periodontitis: a case report.

J Med Case Rep 2018 Dec 11;12(1):365. Epub 2018 Dec 11.

Department of Oral and Maxillofacial Surgery, Graduate School of Medical and Dental Sciences, Tokyo Medical and Dental University, 1-5-45 Yushima, Bunkyo-ku, Tokyo, 113-8549, Japan.

Background: Epithelioid cell granuloma with caseating necrosis is a typical pathological finding in tuberculosis. While specific inflammation, including that related to tuberculosis, can induce caseating granuloma formation, there have been very few reports on the induction of caseating granuloma by non-specific inflammation. Chronic periapical periodontitis is usually related to bacterial biofilm formation as well as fungal or viral infection in the periapical lesion. Read More

Ultrasound-guided trigeminal nerve block and its comparison with conventional analgesics in patients undergoing faciomaxillary surgery: Randomised control trial.

Indian J Anaesth 2018 Nov;62(11):871-875

Department of Dentistry, AIIMS, Patna, Bihar, India.

Background And Aims: Ultrasound (USG)-guided injection in pterygopalatine fossa is an indirect approach to block the trigeminal nerve. Trigeminal nerve block for maxillofacial surgeries may provide preemptive analgesia, reduce opioid consumption and opioid-related adverse effects.

Methods: In this randomised, prospective double-blind study, 60 American Society of Anesthesiologists I/II patients, within the age group of 18-60 years scheduled for faciomaxillary surgery (fracture/pathological lesion of maxilla or mandible and cleft lip), were recruited. Read More

High serum MMP-14 predicts worse survival in gastric cancer.

PLoS One 2018 7;13(12):e0208800. Epub 2018 Dec 7.

Research Programs Unit, Translational Cancer Biology, University of Helsinki, Helsinki, Finland.

Matrix metalloproteinases (MMPs), endopeptidases with diverse biochemical functions, can promote cancer cell invasion and metastasis by degrading the extracellular matrix. A high matrix metalloproteinase-14 (MMP-14) expression in gastric cancer tissue has been associated with metastasis and poor prognosis. To further understand this association, we investigated serum MMP-14 as a biomarker in gastric cancer patients. Read More

Non Surgical Rhinoplasty: Nasal Grid Analysis and Nasal Injecting protocol.

Plast Reconstr Surg 2018 Nov 26. Epub 2018 Nov 26.

Chief of Division of Dental and Maxillofacial Surgery, G.B. Rossi Hospital and Medical University of Verona, Piazzale L.A. Scuro 10, 37134 Verona, Italy.

Objective: Non-surgical rhinoplasty using injectable fillers, in contrast to traditional but more invasive surgery, offers low morbidity, improved skin quality and texture, cost-effectiveness and quick recovery. The aim of this study was to provide a valid and customized protocol for injecting the nose with the aid of a nasal grid to achieve constant attractive results.

Materials And Methods: From January 2015 and October 2018 150 consecutive patients entered the non-surgical rhinoplasty trial. Read More

Application of Three-Dimensional Printing Technology for Improved Orbital-Maxillary-Zygomatic Reconstruction.

J Craniofac Surg 2018 Dec 10. Epub 2018 Dec 10.

Department of Oral and Maxillofacial Surgery, the Second Hospital of Shandong University.

The reconstruction of orbital-maxillary-zygomatic complex (OMZC) on patients suffering from trauma and space-occupying lesions is challenging due to the irregularity of craniomaxillofacial bones. To overcome the challenge in precise OMZC reconstruction, individual three-dimensional (3D) disease models and mirror-imaged 3D reconstruction models were printed on the basis of the computer tomography. Preoperative planning by rehearsing surgical procedures was made on the 3D disease models and the scaffolds including titanium and absorbable meshes or plates were anatomically premolded using the mirror-imaged 3D models as guide.
