Variant Anatomy of the Subhyoid Muscles in the Aspect of Surgical Interventions

Abstract

The aim of the study was to obtain new data on the variant anatomy of subhyoid muscles, which makes it possible to improve the quality of planning and conducting surgical interventions. Materials and methods. The variant anatomy of sterno-hyoidum, sterno-thyroid, scapular-hyoid, thyrohyoid, thyroglandular-hyoid, fascio-thyroglandular and thyro-glandular muscles was studied on 470 non-fixed corpses of 17-85 years old. The variants of their number, shapes, sizes, places of origin and attachment, topography were determined. Identification of muscle tissue was performed with a modified Ziller solution. The results were processed using descriptive statistics. Results. It has been established that the width of the subhyoid muscles of the neck always exceeds their thickness, stipulating their planar structure and shape. Gender peculiarities of the studied anatomical formations have been revealed. The revealed regularities of muscular tissue distribution in subhyoid region in the frontal and sagittal planes can be used in study of embryogenesis. Conclusions. The obtained features of muscles topography will allow to optimize the operative access to the organs of the anterior region of the neck, can help to improve the cosmetic result of the operation.
