RT Journal Article T1 Prestyloid compartment of the parapharyngeal space: a histological study using late-stage human fetuses A1 Katori, Yukio A1 Kawase, Tatsuaki A1 Cho, Kwang Ho A1 Abe, Hiroshi A1 Rodríguez Vázquez, José Francisco A1 Murakami, Gen A1 Abe, Shinichi AB PurposeAlthough the prestyloid space is well known, its definition still remains unclear.MethodsUsing semiserial sagittal sections of 15 late-stage human fetal heads, we studied details of the topographical anatomy.ResultsA definite posterior marginal fascia of the space was seen along the anterior aspect of the stylopharyngeus and styloglossus muscles. Inferiorly, the prestyloid space faced the bucallis and medial pterygoid muscles and the submandibular gland. The external carotid artery ran along the posterolateral side of the space. The tensor veli palatini fascia did not contribute to the posterior marginal fascia. A major supplying artery of the space was the ascending palatine artery.ConclusionsThe prestyloid compartment of the parapharyngeal space (hereafter, the prestyloid space) seems to correspond to a border between the first and second pharyngeal arch derivatives. This concept may provide a better understanding of prestyloid space.
