Purpose. There are, in general, few published series on chordoma. It is a rare disease and further data are still needed.Patients/methods. The data of 37 patients with chordoma were retrospectively analyzed. Treatment was surgical excision in 11, radical radiotherapy in 9 and a combination of the two in 16 cases. The male to female ratio was 2.7 : 1. Median age was 59 years (range 1-89 years).R...

OBJECTIVES This study examines the relationship between spheno-occipital synchondrosis (SOS) closure and puberty onset in a modern American population. It also investigates the timing and the rate of SOS closure in males and females. MATERIALS AND METHODS The sample includes cross-sectional and longitudinal 3D Cone Beam Computed Tomography (CBCT) scans of 741 individuals (361 males and 380 fe...

I n our last article 1 we described the external features which characterize the cranial and facial structures of the cranial strains known as hyperflexion and hyperextension. To understand how these strains develop we have to examine the anatomical relations underlying all cranial patterns. Each strain represent a variation on a theme. By studying the features in common, it is possible to acco...

Background: Considering the late ossification potential of spheno-occipital synchondrosis (SOS), it can be used as a tool to estimate age in adolescents. The time SOS fusion is known vary different populations. Objectives: This study aimed assess degree Iranian individuals, using cone-beam computed tomography (CBCT) scan. Patients and Methods: CBCT images 240 patients (126 females 114 males), a...

INTRODUCTION In the opinion of the famous anatomist Testut, the skull base is similar to a ship. This illustrative image obviously takes into consideration the existence of a bow designed to balance the undulatory movements caused by the C1 – C2 occipital articulations. It’s about the exoskull, which allows through its apophyses the insertion of various muscle groups which ensure the equilibriu...
