A frontotemporal craniotomy is usually performed using a "keyhole," made at the union of the zygomatic arch and frontal bone. Consequently, skull depression may occur postoperatively, leading to temporal area deformities and poor cosmetic results. To prevent these complications, we describe our technique for frontotemporal craniotomy using an osteotome to prevent cosmetic deformities. After the...

The current understanding of the response of the frontal bone to blunt impact is limited. Previous studies have utilized vastly different methods which prevents statistical analyses to determine the tolerance of the frontal bone. The purpose of this study is to determine the tolerance of the frontal bone to blunt impact and to define corridors describing its forcedisplacement response. The resp...

OBJECTIVE To clarify the spatial orientation relevant to the endoscopic sinus surgery (ESS) for the frontal sinus. METHODS Various dimensions of structures around the frontal recess were measured on 256 CT images of 128 Japanese patients using the multiplanar reconstruction technique. Measurements done in this study were: the distance from the nostril to the narrowest point of the frontal rec...

AIM To study a rare clinical case of isolated primary osteoma localized in the frontal bone, provide its detailed clinical and pathomorphological analysis, and evaluate statistical indicators of occurrence frequency and localization of facial skeleton osteomas during 2006-2015. MATERIALS AND METHODS The retrospective case records analysis of patients undergoing treatment in the ma-xillofacial...

Abstract Two widely accepted conceptual models of extratropical cyclone structure and evolution exist: the Norwegian Shapiro–Keyser models. The model was developed around 1920 by Bergen School meteorologists. This has come to feature an acute angle between cold warm fronts, with reduction in area sector during corresponding formation occluded front. 1990 motivated recognition alternative fronta...
