Abstract

Background: the thyroidal pyramidal lobe is considered a congenital malformation on which the accumulated knowledge is scarce and very limited, coming mainly from researches in corpses and image studies. The aim of the current research was determining the morphometric characteristics of the thyroidal pyramidal lobe in surgically treated patients.
Materials and methods: a descriptive, observational, prospective research with historical cohort was carried out in a universe of 116 patients, aged more than 16 years, who were surgically treated due to any no deforming condition of the thyroidal gland in the Teaching Provincial Hospital “Celia Sanchez Manduley”, in Manzanillo, Granma. The used way of surgical access was the Kocher´s horizontal cervicotomy. In the cervicotomy course, the thyroidal pyramidal lobe was observed and the lobe was extracorporeally measured after the reception was practiced.
Outcomes: thyroidal pyramidal lobe was present in 77 patients (66,38 %); its link with the gland was more frequent in the left lobe (49,35 %) being the conical form the most observed one (31,17 %). The average length was 4,01 ± 2,01 cm.
Conclusions: the thyroidal pyramidal lobe is a congenital malformation of the thyroidal medial and lateral outline that is present in more than half of the individuals, frequently having conical form, linked to the thyroidal gland left portion with an average length of 4,01 cm.
