Metric analysis of basal sphenoid angle in adult human skulls.

Objective: To analyze the variations in the angle basal sphenoid skulls of adult humans and their relationship to sex, age, ethnicity and cranial index.

Methods: The angles were measured in 160 skulls belonging to the Museum of the Universidade Federal de São Paulo Department of Morphology. We use two flexible rules and a goniometer, having as reference points for the first rule the posterior end of the ethmoidal crest and dorsum of the sella turcica, and for the second rule the anterior margin of the foramen magnum and clivus, measuring the angle at the intersection of two.

Sonographic aspects and anatomy of the aponeurosis of transversus abdominis muscle.

Background: Ultrasound, computed tomography, and magnetic resonance imaging of abdominal wall has increasingly been used for hernia diagnosis when clinical examination is uncertain. Anatomical study of abdominal wall along with the ultrasound of transversus abdominis muscle aponeurosis can help identify a Spigelian hernia in this region, a disease of difficult diagnosis.

Aim: To compare the ultrasound findings of anterolateral wall of the abdomen, focusing on Spigelian aponeurosis, to the anatomy of abdominal wall studied in cadavers.

Application of high frequency bipolar electrocoagulation LigaSure™ in appendix vermiformis of rabbits with or without acute inflammatory process.

Purpose: To evaluate the efficacy of the use of LigaSure™ in appendectomy, with or without acute inflammatory process, and to compare with simple ligature and conventional therapy.

Methods: A total of 30 rabbits (Oryctolagus cuniculus) randomly allocated in two groups, group A and B, of 15 animals each were used. The group A without acute appendicitis and the group B with acute appendicitis were submitted to appendectomy.
