Description
Summary:Knowledge of the anatomy of musculoskeletal system of the anterior neck region is crucial for the good practice of health personnel. In this area, both muscular and vascular systems are closely related, and the anatomical variations that may occur could alter blood conduction or hinder medical and surgical maneuvers. This study reports a case of unilateral duplicated omohyoid muscle and its merger with an anomalous sternohyoid muscle with an intermediate tendinous formation and discusses its clinical importance. This alteration might have represented a problem at a surgical reconstruction of diverse neck structures, in case of having specified one. Besides, a large-flow collateral vein system has been observed, which could also have played an important role in the consequences of this anatomical muscle variation. Thus, it is considered as of importance to report on the anatomical variations found in human dissections, both for basic science researchers and for professionals dedicated to clinical science.
