Very few surgical teams currently use totally independent and free solutions to perform three-dimensional (3D) surgical modelling for osseous free flaps in reconstructive surgery. This study assessed the precision and technical reproducibility of a 3D surgical modelling protocol using free open-source software in mandibular reconstruction with fibula free flaps and surgical guides. Precision was assessed through comparisons of the 3D surgical guide to the sterilized 3D-printed guide, determining accuracy to the millimetre level...

Myoepithelial cells (MECs) are implicated in the development and progression of human salivary gland tumours. Here, we investigate the potential role for MECs in invasion and metastasis of carcinoma ex pleomorphic adenoma (CXPA). Tumour tissues from 40 CXPA patients diagnosed between 1960 and 2014 were obtained. Patient samples were divided into two groups (non-invasive tumours, n=10; and frankly invasive tumours, n=30). Each group was further divided into two subgroups (metastatic tumours and non-metastatic tumours)...

As there is currently no internationally accepted outcome measurement tool available for complete bilateral cleft lip and palate (CBCLP), the goal of this prospective study was to develop a numerical evaluation scale that allows reliable scoring of this cleft deformity. Our cohort comprised 121 Indian subjects with CBCLP who underwent surgical repair (mean age at time of surgery 6.53 months) using a modified Millard technique. A panel of three professionals evaluated each subject's outcome of bilateral cleft lip repair 6 months postoperatively on two-dimensional (2D) full-face photographs in the frontal view and worm's eye view...

Microvascular free flaps are considered to be the gold standard in reconstructive head and neck surgery. However, reduced postoperative transplant perfusion is one of the serious postoperative complications and calls for close and reliable monitoring. Procalcitonin, C-reactive protein, and leukocytes are closely associated with local and systemic inflammatory reactions and might have prognostic capacity concerning tissue necrosis. This study aimed to evaluate perioperative serum levels of these three biomarkers to assess their potential in postoperative flap monitoring...

While the oral health-related quality of life (OHRQoL) is known to be reduced in patients with cleft lip and palate (CLP), its inter-dependency with the soft tissue characteristics of the CLP area remains unclear. This study aimed to evaluate the soft tissue characteristics in the treated cleft area in order to investigate whether gingival esthetics correlate with OHRQoL. Thirty-six patients with unilateral or bilateral CLP (46 cleft areas) were investigated after secondary/tertiary alveolar bone grafting and orthodontic/prosthetic implant treatment using an adapted score to rate gingival esthetics (clinical esthetic score, CES)...

Craniosynostosis is a congenital defect which can result in abnormal cranial morphology. Three dimensional (3D) stereophotogrammetry is potentially an ideal technique for the evaluation of cranial morphology and diagnosis of craniosynostosis because it is fast and harmless. This study presents a new method for objective characterization of the morphological abnormalities of scaphocephaly and trigonocephaly patients using 3D photographs of patients and healthy controls. Sixty 3D photographs of healthy controls in the age range of 3-6 months were superimposed and scaled...

Le Fort I osteotomy is the technique most applied worldwide in the treatment of dentoskeletal deformity involving the maxilla. Even though it is considered a very safe technique with good intra- and postoperative results, many complications have been described. This paper presents a case of carotid jugular fistula developed in a 22-year-old white male submitted to Le Fort I osteotomy for the treatment of anteroposterior maxillary deficiency, and discusses the possible aetiology and management of this serious complication...

Despite complete resection of the early stage of oral tongue cancer by partial glossectomy, late cervical lymph node metastasis is frequently observed. Gene amplification of ACTN4 (protein name: actinin-4) is closely associated with the metastatic potential of various cancers. This retrospective study was performed to demonstrate the potential usefulness of ACTN4 gene amplification as a prognostic biomarker in patients with stage I/II oral tongue cancer. Fifty-four patients with stage I/II oral tongue cancer were enrolled retrospectively, in accordance with the reporting recommendations for tumour marker prognostic studies (REMARK) guidelines...

H-L Kim, J-S Kwon, Y-J Choi, U-L Lee
During a reduction malarplasty, precise sectioning of the zygomatic arch according to the plan formulated in the diagnostic stage is very important, because differences in the locations of the osteotomies in the left and right zygomatic arch will result in facial asymmetry, and arch osteotomies that are placed at locations other than those specified during planning elicit unwanted results. A method for the precise planning and sectioning of the zygomatic arch involving the use of computed tomography (CT) and a viewer program is presented herein...
