ore affected than males, with a ratio of 12/13 (92%). The most frequent side affected was maxilla 10/13 (77%) and the most type of defect reported was horizontal 10/13 (77%). The means in width (x = 8,2923) and height (x = 6,9615) of the 3D model, were close and clinically acceptable if compared with the means obtained from the measurements in width (x = 7,9230) and height (x = 6,8076) of the patients' bone defects. None of the patients underwent further surgeries or needed intraoperative surgical corrections obtaining reliable results in terms of presurgical planning.It is possible to affirm that the use of 3D printed models can be a crucial complement when planning guided bone regeneration procedures, due to high reliability, and representing a turning point in many aspects of oral surgery.

Distraction osteogenesis (DO) is a highly effective technique for correction of severe maxillary hypoplasia, especially in patients with orofacial clefts and craniofacial syndromes. The purpose of this retrospective, longitudinal study was to assess long-term airway alterations after maxillary advancement using a rigid external distraction system (RED) in non growing cleft patients. Fifteen cleft patients (8 males and 7 females) aged from 14 to 25 years were included in this study. All of them were treated with a rigid external distraction system for maxillary advancement after a high Le Fort I osteotomy. To analyse airway changes lateral cephalograms were obteined before distraction (T0), immediately after distraction (T1) and 1 to 3 years and 3 months after distraction (T2). All the measurements were describled by means of median, minimum and maximum. In order to evaluate differences between each time interval, a Wilcoxon test associated to a Delta Cliff test was used to evaluate the effect size (level ofand increased antero-posterior upper airway dimension was measured immediately after maxillary distraction with rigid external distraction in non growing cleft patients. The findings were stable three years after distraction.

To explore the clinical effect of sellar floor bone flap with a pedicled nasoseptal flap in endoscopic transnasal pituitary adenoma surgery for skull base reconstruction.Method This was a retrospective clinical analysis of 30 patients with pituitary adenoma operated by the same neurosurgical team from June 2015 to June 2018. All patients were diagnosed with pituitary adenoma by pituitary magnetic resonance imaging, and the authors confirmed that the sellar floor bone was intact using sphenoid sinus computed tomography. All patients underwent an endoscopic transnasal approach, and the authors created a pedicled nasoseptal flap and sellar floor bone flap intraoperatively and reconstructed the skull base at the end of the surgery. Postoperative complications constituted cerebrospinal fluid leakage, brain tissue herniation, nasal discomfort, decreased sense of smell, and epistaxis.

Cerebrospinal fluid leakage occurred in 13 patients (43.3%) intraoperatively; small amounts in 6 patients (20.0%), moderate amound brain tissue herniation in endoscopic transnasal pituitary adenoma surgery and did not increase the incidence of postoperative nasal discomfort, decreased sense of smell, or epistaxis.

This is the first report of multiple parosteal lipomas as a late complication of aesthetic procedures. A 70-year-old woman presented with multiple frontal nodules that had grown slowly over 5 years. She underwent forehead-lifting surgery 30 years ago and botulinum toxin injection 3 years ago. selleck kinase inhibitor Computed tomography showed six low-density nodules measuring 10 to 20 mm just above the frontal bone. The tumors were resected via a parietal coronal incision. Histopathological findings revealed parosteal lipoma with foreign bodies. At 1 year postoperatively, there has been no recurrence or complications. The multiple lesions corresponded to the sites of the aesthetic procedures. The mesenchymal cells in the periosteum seemed to be stimulated by cytokines released from a postoperative hematoma or damaged periosteum, resulting in tumorigenesis. When performing aesthetic procedures in the face, care should be taken to avoid unnecessary injury to the periosteum, given the possibility of tumor development.Level of evidencpment.Level of evidence Level V, case report.

Microtia is a severe congenital malformation of the external ear. This study aimed to explore the epidemiologic characteristics and the possible risk factors in patients with severe microtia in China, and integrate significant variables into a predictive nomogram.

A total of 965 patients with microtia were included. This retrospective case study was conducted from July 2014 to July 2019 at Plastic Surgery Hospital in China. The detailed questionnaires concerning potential risk factors were completed and data were gathered. Chi-Square and Fisher tests were used to analyze the variables, and a multivariate logistic regression model was used to select variables related to severe microtia, and then construct a nomogram. The nomogram model was evaluated by the concordance index (C-index), calibration plot, and receiver operating characteristics (ROCs) curve. Bootstraps with 1000 resamples were applied to these analyses.

Of the 965 microtia patients, 629 (65.2%) were male and 867 (89.8%) were sporadic. The caotia patients are male, sporadic, and accompanied by other malformations, which are similar to the phenotypic analysis results of other studies. A nomogram predicting severe microtia was constructed to provide scientific guidance for individualized prevention in clinical practice.

Palatal fistulae are common complications of cleft palate surgery with a frequency of 5% to 29% and are challenging to repair. Optimal timing to repair palatal fistulae, in a staged fashion before alveolar bone grafting, or at the same time, still remains controversial. The primary aim of this study is to compare outcomes of 2 groups with regard to successful alveolar bone grafting in patients with cleft lip and palate and palatal fistulae. We describe a review of 85 consecutive patients identified as undergoing bone grafting from a single institution craniofacial team during 2003 to 2018. Twenty-eight required palatal fistula repair. All patients had a diagnosis of unilateral or bilateral complete cleft lip and palate. Patients with cleft lip and palate repairs were stratified based on preoperative or simultaneous palatal fistula repair. Panoramic radiographs were reviewed by 2 physicians to evaluate success of bone grafting. Comparison between cohorts was made by statistical analysis. Of the 28 that required palatal fistula repair, 15 (53.
