The maxilary nerve can be block in the pterygopalatine fossa, entering from oral cavity via greater palatine canal. The aim of this study was to analyse the volume of the pterygopalatine fossa and its relationship with upper facial height and cephalic indexes. In 71 human adults skulls, without sex distinction, was determined the volume of the pterygopalatine fossa and cephalic and upper facial height indexes. Through a t test (p < 0.05) were compared the average volume between cephalic and facial types. The average volume of the pterygopalatine fossa was 1.2 ml (DS 0.297), were not found differences according to the cephalic or facial type. [ABSTRACT FROM AUTHOR]

The mandibular canal have as longitudinally course, being related in its average segment to the dental pieces molars and premolars. The knowledge of the relation of the mandibular canal with the dental pieces and cortical bone is of great importance for the practice of the implant therapy. In the present study the relations of the average portion of the canal are analyzed to mandible with cortical mandibular bone pertaining to female sex of between 50 and 65 years obtained of different cemeteries, with coincident anthropometric characterization with the registry. Measurements were made in three levels of the average segment (A-B-C). The results show that the mandibular canal presents a ovoid form and that their diameters diminish as it descends until the mentoniano hole. It was observed, in addition an oblique and descendent passage, coming near to the cortical one to vestibular of the jaw. The importance of the knowledge of the biometrics aspects of the mandibular canal is discussed in female of the selected age group, because they are these patients who have greater necessity of implant therapy.

Varied methods exist to realize the medicolegal identification in cadaveric remains or skeletons, one of them is the identification for forensic sculpture. For this certain references are needed in the relation between osseous and soft tissue. The objective of this investigation was to determine face tissue thicknesses by means of ultrasonography and to correlate them with age and sex. There was selected a sample of 48 persons, between 21 and 50 years of age of both sexes, which they consulted to the service of imagenología of Talcas Multimedical Clinic distributed in two groups: A group with 12 men and 12 women between 21 and 35 years of age; B group with 12 men and 12 women between 36 and 50 years of age. For this study an ecographe was used, General Electric®, model voluson 730 expert, to which the tissue thicknesses measured up in 15 medium and paramedium craniofacial points, which were correlated by the parameters of sex and age. The results of the measurement of the tissue thicknesses showed significant differences between age groups and between sexes. Significant differences were not observed, between the persons of the same sex of the same age group. [ABSTRACT FROM AUTHOR]
