Anatomicosurgical References for Endoscopic Localization of Sphenopalatine Foramen: A Cadaveric Study

[Anatomic variations and references of the sphenopalatine foramen in cadaveric specimens: a Mexican study].

BACKGROUND The sphenopalatine foramen is located on the lateral nasal wall and has multiple variants and anatomic landmarks that are important to know to optimize RESULTS in the surgical management of posterior epistaxis. OBJECTIVE This study describes the endoscopic anatomy of the sphenopalatine foramen, related structures and anatomic variations in a Mexican population. METHODS We perform...

Landmarks for rapid localization of the sphenopalatine foramen: A radiographic morphometric analysis

BACKGROUND Transnasal endoscopic sphenopalatine artery ligation is becoming the procedure of choice for surgical management of intractable posterior epistaxis. Landmarks for localization of the sphenopalatine foramen can assist in rapid surgical exposure of the sphenopalatine artery. OBJECTIVE This study examined distances from easily identified endoscopic surgical landmarks to the sphenopala...

Mapping surgical coordinates of the sphenopalatine foramen: surgical navigation study.

OBJECTIVES To identify measurements that may help intra-operative localisation of the sphenopalatine foramen. DESIGN The study used three-dimensional surgical navigation software to study radiological anatomy, in order to define the distances and angulations between identifiable bony landmarks and the sphenopalatine foramen. RESULTS The distance from the anterior nasal spine to the sphenopa...

a study on thermodynamic models for simulation of 1,3 butadiene purification columns

attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
