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.

Refractory Severe Thrombocytopenia during Pregnancy: How to Manage.

Rev Bras Ginecol Obstet 2018 Dec 7;40(12):803-807. Epub 2018 Dec 7.

Department of Anaesthesiology, Centro Hospitalar Lisboa Norte, Lisboa, Portugal.

Thrombocytopenia is the most common hemostatic change in pregnancy, but severe thrombocytopenia is rare. One of the causes, immune thrombocytopenic purpura (ITP), is characterized by increased platelet destruction by immunoglobulin G (IgG) antibodies, presenting a high risk of hemorrhage for the patient, but also for the fetus, since antibodies may cross the placenta. We present the case of a 23-year-old pregnant woman with a history of Langerhans cell histiocytosis of the mandible submitted to surgery and chemotherapy when she was 10 years old, with diagnosis of ITP since then.

Background: Controversy exists regarding the treatment of mandibular hypoplasia in craniofacial microsomia patients, notably the role of mandibular distraction osteogenesis. The authors compared the need for orthognathic surgery in skeletally mature craniofacial microsomia subjects who either did (study group) or did not (control group) undergo early mandibular distraction osteogenesis.

Methods: A retrospective review was conducted of all craniofacial microsomia patients evaluated between January of 1993 and March of 2017. Read More

Linear Predictors of Facial Rotation Pattern in Croatian Subjects with Skeletal Class III Malocclusion.

Acta Stomatol Croat 2018 Sep;52(3):227-237

Department of Orthodontics, School of Medicine, University of Rijeka, Croatia.

Objectives: The objective of this study was to determine whether the linear measures of the maxilla, mandible and cranial base were predictors of facial growth rotation in a Croatian population with Class III malocclusion by cephalometric radiographic methods.

Material And Methods: The examined sample consisted of pretreatment lateral cephalometric records of 201 (111 females and 90 males) untreated Class III patients of Caucasian Croatian ancestry from the Department of Orthodontics at Zagreb University. The measurements were divided into five categories for analysis: cranial base, skeletal maxillary and skeletal mandibular relationships, sagittal intermaxillary and vertical relationships. Read More
