Craniofacial microsomia (CFM) is most often described as a unilateral malformation of derivatives of the first and second branchial arches. The mandible has been classified using several classification systems. However, all are based on two-dimensional imaging. The aim of this study was to mathematically describe the deformed mandible based on principal component analysis (PCA) in a three-dimensional way. This may aid in defining the flaws in existing surgical corrections of the mandible through the identification of the differences in shape compared with a normal mandible in a holistic view with the help of videos...

Face-bow transfer is an essential step in articulator-based orthognathic surgery planning. However, it can be a source of inaccuracy. Virtual computer-based planning avoids this error through the use of direct patient-related three-dimensional imaging data. The aim of this prospective observational study was to determine the error of face-bow transfer three-dimensionally and correlate it to the different types of malocclusion. Orthognathic surgery performed on 38 patients (10 male, 28 female; mean (standard deviation) age 24...

The aim of this study was to determine the prevalence, localization, and width of the foramen of Huschke (FH) and the relationship between age and FH. Another aim was to investigate the development of spontaneous temporomandibular joint (TMJ) herniation. This was a retrospective review of high-resolution computed tomography images of the temporal bone of 1025 patients. The prevalence of FH and the axial and sagittal diameters of the foramen were evaluated. Cases were found in which the TMJ had herniated through FH into the EAC...

Pai syndrome was originally described as the association of a midline cleft lip, midline facial polyps, and lipoma of the central nervous system. However, only a few patients present with the full triad, and most exhibit a wide spectrum of phenotypic variability. The aim of this study was to phenotypically delineate Pai syndrome and to propose new criteria to facilitate a clinical diagnosis in the future. The study cohort consisted of seven case patients and an additional 60 cases diagnosed with Pai syndrome identified in a literature review...

The aim of this study was to identify intraoperative factors associated with free flap failure. The outcomes of 216 patients (220 flaps) were analyzed retrospectively. A statistical analysis was performed to determine the association of flap failure with the intraoperative factors of prolonged operation time, flap type, vascular pedicle at the recipient site, and use of vasoactive medication. A review of the recent literature was also conducted to identify other intraoperative risk factors. Univariate regression analysis revealed that a prolonged operative time (P=0...

Seborrhoeic keratosis and actinic keratosis are common skin lesions, and the latter is a precursor for skin malignancy. The treatment regime can be lesion-directed or field-directed. Current lesion-directed treatments include cryotherapy, shave excision, and laser ablation. Field-directed treatment typically encompasses multiple topical agents. This article presents the authors' experience of lesion- and field-directed erbium:YAG laser treatment of 547 patients (Fotona Dualis XS Laser). In this series of patients, those who had resurfacing as field therapy showed no recurrence during the 12-month review period...

The control of local failure (LF) is essential to improve outcomes in patients with squamous cell carcinoma of the oral cavity (OSCC). In this study, LF of OSCC was classified into three clinical types: deep recurrence (type 1R), adjacent superficial recurrence (type 2R), and distant primary tumour (type 3R). LF was analyzed after surgical resection of OSCC to determine the validity and usefulness of this classification system. Of 257 patients with OSCC, 58 experienced LF; 21 had type 1R, 23 had type 2R, and 20 had type 3R...

The objective of this project was to retrospectively evaluate changes in volume of different compartments of the upper airway in response to maxillary, mandibular, and bimaxillary advancement surgeries and to predict the extent of volumetric changes associated with these surgical movements. Pre- and post-surgical cone beam computed tomography scans of 36 patients were evaluated for changes in nasal cavity, nasopharyngeal, oropharyngeal, and hypopharyngeal compartments. The amount of movement for each surgery was measured from skeletal landmarks to reference planes and was correlated with volumetric changes...

Autotransplantation of premolars is a well-established method to rehabilitate aplasia of premolars. Nevertheless, with the introduction of titanium implants, not all surgical units offer this procedure. The aim of this study was to examine the predictability of autotransplantation of premolars on orthodontic indication as suggested by Andreasen et al., when performed by surgeons with or without prior experience of this procedure. A prospective protocol was implemented in 2001. All patients treated with autotransplantation of premolars during the years 2001-2015 were recalled to evaluate the long-term status of the teeth...

Oral lichenoid reaction, an immune-related adverse event of immunotherapy, has been reported in very few patients receiving anti-programmed cell death receptor-1 (anti-PD-1) therapy. Here, we describe a case of severe stomatitis (grade ≥3 by the Common Terminology Criteria for Adverse Events, version 4.0) accompanied by pharyngolaryngitis that was observed in a patient receiving nivolumab therapy. The stomatitis was diagnosed as drug-induced lichenoid reaction. Nivolumab therapy was discontinued, and the patient was administered systemic prednisolone (1mg/kg)...

The objectives of this systematic review were to investigate the efficacy of amoxicillin/amoxicillin-clavulanic acid for reducing the risk of postoperative infection after third molar surgery and to evaluate the adverse outcomes in these patients, as well as in healthy volunteers. A systematic search of four databases was performed on May 26, 2017. Eleven studies qualified for the qualitative analysis and eight were found suitable for meta-analysis. The results suggest that both amoxicillin-clavulanic acid and amoxicillin significantly reduce the risk of infection after third molar extraction (overall relative risk (RR) 0...
