Bases anatómicas en la anestesia odontológica demostradas a través de la disección cadavérica

Abstract

The Oral and Maxillofacial Surgeon executes clinical and anesthetic maneuvers that are directly concerned to the orofacial region. For this reason, knowing the distribution territory of anatomical structures, especially the trigeminal nerve dependent, allows the surgeon to have greater security when performing clinical procedures, avoiding potential iatrogenic, while maintaining the integrity of the peripheral nerves. The purpose of this research, is to present through dissections in cadaveric pieces, the peripheral distribution of collateral branches of maxillary nerve (V2) and Mandibular (V3), emphasizing its importance in dental anesthesia. Manual work was done at the dissecting room of the Department of Human Anatomy, Faculty of Dentistry of the Universidad de Los Andes. 8 hemi human heads from adult cadavers were prepared , treated with 10% formaldehyde and preserved in undiluted GerdexR for 6 months priorthe execution of the work, and later, under the current protocols, dissections of the elements under study were performed, which were individualized in order to illustrate their distribution territory. The use of cadaver dissection, as a teaching tool in the teaching-learning process, leads to cognitive challenges allowing visualization of various anatomical territories, identifying the present structures in each of the covered planes by recognizing and linking the anatomical structures within a three dimensional context close to human body reality.
