The Pars Angularis Fascia Colli; What is it? Proposal For a Correct Anatomic Term

The pars angularis of the superficial layer of the neck fascia is poorly described in anatomical and surgical literature, it is a part of the fascia of the neck not very well known, but constant, whose description and location have been studied by anatomists, and its relevance in neck and maxillofacial surgery is currently recognized. A review of classic anatomy books and articles related to this subject was conducted. The different anatomical characteristics of these fascias were precisely explained, detailing their shapes, boundaries, insertions, and relationships within the suprahyoid region. The different names used and the errors in their interpretation are also being discussed. After analyzing the consulted bibliography and given the results, it was proposed a complete description of the pars angularis fascia colli and a nomenclature based on the principles of Terminologia Anatomica (TA), also suggesting a change of terminology according to the principles of the Federative International Programme for Anatomical Terminology (FIPAT): pars angulus mandibulae-sternocleidomastoideus fasciae cervicalis.
