Anatomic study of the discomalleolus ligament

Topographic descriptive contribution for capturing images

Abstract

Introduction: The obtaining of reliable structures that form the temporomandibular joint (TMJ) images has always been a challenge for professionals who work in the study and treatment of the problems that affect this joint. Objective: Since the discomalleolus ligament can promote a union between a temporomandibular joint and the middle ear, and that auditory disorders are usually related to the temporomandibular disorders, which makes it difficult to diagnose it, this study proposes anatomically an orientation for identification of the ligament for the guidance control to capture images of the discomalleolus ligament in the petrotympanic fissure. Methods: Subsidized by cadaveric dissection a measurement of planes through sections in dry skull through the formation of a three-dimensional prototype was performed. The study had the release from the anatomy department from the Federal Univesity of Pernambuco. Conclusion: The guidelines generated from the topographic-anatomical study are effective in determining the discomalleolus ligament in radiological images.
