Individual and ethnic aspects of preoperative planning for posttraumatic rhinoplasty
The aim of this study was to compare the aesthetic results of post traumatic rhinoplasty among Europeans with populations of healthy Caucasians described in earlier reports, and to collate correct parameters of nasal shape in healthy representatives of both sexes and various races for improvement in aesthetic results of surgery. 3-D scanning of the face was performed in 54 patients after posttraumatic septorhinoplasty. Analysis of 3D model was based on two indices of the nasal proportions and four angles of the region from 18 anthropological points. Parameters of the nasal shape in addition to gender were compared to average values of healthy Caucasian population, described before. Normal characteristics of the nose among individuals of three races from previous studies were also compared to one another. In females, mean height and width of the nose as well as length of both nostrils was smaller. Neither were there any significant differences in width of the nostrils and length of the nasal pyramid nor nasal prominence. Nasal proportions were similar in both sexes. Some of the nasal angles differed in addition to gender. Posttraumatic rhinoplasty resulted in correct shape of the nose similar to the healthy Caucasian population. The aesthetic nose differ among healthy individuals of the three races analysed. While preoperative planning is important, knowledge of the normal values of parameters characterising shape in both genders is equally important as the individual differences in relation to the whole face

Sonoelastographic Evaluation of the Masseter Muscle before and after Mandibular Setback Surgery
Aims: The purpose of this study is to compare the thickness and elasticity of the masseter muscle before and after orthognathic surgery in patients with class III skeletal deformity and to investigate the relationship between the sonographic changes in the masseter muscle and the amount of mandibular setback. Subjects and Methods: The study group consisted of 14 patients with skeletal class III malocclusions who had orthognathic surgery. The control group consisted of 14 patients who had dental and skeletal class I occlusion. Muscle thickness measurements were performed with B-mode and high-frequency linear scanning probe of the ultrasound device. Elastography feature and muscle hardness ratio were obtained by applying compression and decompression on muscles at rest and during maximum contraction in the transverse plane. Patients were categorized into two groups according to the mandibular setback as <5 mm and ≥5 mm. Results: The masseter muscle thickness after surgery was found statistically increased bilaterally in both at rest and during contraction for the study group (P < 0.05). No difference was found between preoperative orthognathic measurements and postoperative measurements for elasticity index ratio measurements (P > 0.05). Conclusion: We believe that in the present study important findings have been emphasized for further research aiming to investigate the possible relationship between masticatory alterations and surgical outcomes after orthognathic surgery
Investigation of the effectiveness of CBCT and gray scale values in the differential diagnosis of apical cysts and granulomas.
Tetrafid mandibular condyle: a unique case report and review of the literature
Morphological changes such as bifid and trifid mandibular condyle are rare entities. The aim of the present report is to describe a unique morphological variation of the mandibular condyle which has four separate condylar heads (tetrafid mandibular condyle) and to discuss clinical and radiological differential diagnosis of tetrafid mandibular condyle with advanced imaging techniques.

Management of a Disarticulation Hemimadibulectomy Defect with Laser Sintering Custom-Made Prosthesis: a Case Report
An unusual case of multilocular Stafne bone cavity
Stafne bone defects (SBDs) are asymptomatic lingual bone depressions of the lower jaw that are frequently caused by soft-tissue inclusion. The common variant of SBD exists at the third molar region of the mandible below the inferior dental canal is an and ovoid-shaped homogeneous well-defined radiolucency. In this report, an unusual occurrence of SBD with multilocular appearance is presented. Asymptomatic lingual bone defects may represent various radiographic features. Detailed radiographic evaluation with CT scans should be performed to differentiate SBDs from other pathologies. Dentomaxillofacial Radiology (2012) 41, 75-78. doi:10.1259/dmfr/3473196
