A surgical navigated cutting guide for mandibular osteotomies: accuracy and reproducibility of an image-guided mandibular osteotomy.

Purpose: 3D-printed cutting guides are the current standard to translate the virtual surgery plan to the intraoperative setting. The production of these patient-specific cutting guides is time-consuming and costly, and therefore, alternative approaches are currently subject of research. The aim of this study was to assess the accuracy and reproducibility of using a novel electromagnetic (EM) navigated surgical cutting guide to perform virtually planned osteotomies in mandible models.

Bloom syndrome does not always present with sun-sensitive facial erythema.

Bloom syndrome is an autosomal recessive condition characterized by severe pre- and postnatal growth deficiency, immunodeficiency, an increased risk for malignancies, craniofacial dysmorphisms, and "typical" erythematous sun-sensitive skin lesions of the face. This facial rash has a butterfly-shaped distribution around the nose and is usually observed for the first time during the early years of life. Though reported as being a main feature of Bloom syndrome, there seems to be phenotypic variability regarding this facial skin rash among patients.

Retroauricular endoscopic and robotic versus conventional neck dissection for oral cancer.

There has been a significant increase in concern towards improving aesthetic and functional outcomes without compromising the oncologic effectiveness in head and neck surgery. The aim of the current study is to assess the feasibility and oncological outcome of the retroauricular approach for endoscopic and robot-assisted selective neck dissection (SND) for oral cancer in comparison with the conventional SND. A retrospective single institute cohort study was designed.

Pharmacological and surgical therapy for the central giant cell granuloma: A long-term retrospective cohort study.

Purpose: This is a retrospective cohort study of patients with a central giant cell granuloma (CGCG) treated at a single center to assess and compare the different surgical and non-surgical approaches.

Material And Methods: A cohort with a single histologically proven non-syndrome-related CGCG was selected and reviewed. Patients were allocated to group I (surgery), group II (pharmacotherapy), and group III (pharmacotherapy and surgery).

Multiple giant cell lesions in a patient with Noonan syndrome with multiple lentigines.

A patient with Noonan syndrome with multiple lentigines (NSML) and multiple giant cell lesions (MGCL) in mandibles and maxillae is described. A mutation p.Thr468Met in the PTPN11-gene was found.

Cephalometric analysis of craniofacial morphology and growth in unrepaired isolated cleft palate patients.

Objective: The aim of this study is to analyze the craniofacial morphology in patients with unrepaired isolated cleft palate (UICP) at childhood, adolescence and adulthood, in order to assess the influence of nonsurgical factors on the craniofacial growth in these patients.

Material And Methods: Lateral and posteroanterior cephalograms of 106 non-syndromic UICP patients and 102 normal matched controls were obtained and analyzed. Patients and controls were divided into three subgroups: children (5-7 years), adolescents (12-14 years), and adults (>18 years).
