Morfologia e variações anatômicas dos ventres frontais do músculo occipitofrontal: estudo anatômico e classificação

Abstract

INTRODUCTION: The development of muscles, myocutaneous, osteomiocutaneous, and the variety of microsurgical flaps, added to the new aesthetic procedures on frontal bellies, became essential the well knowledge of this region. The studied in this paper covered the detailed morphology of the frontal and their anatomical variations, that can serve as useful reference points in reparative and cosmetic surgery. METHODS: We studied 56 non-fixed cadavers, 35 men and 21 women, 37 white and 19 non-white, with age ranging from 19 to 85 years old. In this material, 112 muscles were dissected. RESULTS: Data were available in tables followed by the parameters of sex, age, race, interventricular distances, heights and widths of the frontal bilaterally. The widths, thickness and interventricular distances were measured at 1.5, 3.0 and 4.5 cm from the glabella in both wombs. The frontal were presented in different ways, especially regarding the disposition of the medial and were grouped into four types. CONCLUSION: The extensive anatomical knowledge allows us to a preoperative planning safer
