forms the laryngeal prominence aka Adam’s apple,.Part of Larynx: Cartilages, Membranes, Ligaments, Joints, Muscles Location: Bodies of C3 –> C6, leading from pharynx –> tracheaįunction: regulate flow of air to and from lungs for vocalization = voice production, guard air passages, so food and liquids don’t enter it Lymph drainage: deep cervical and paratracheal l.n.

Anatomy of pharynx, larynx and thyroid gland. The anatomy, histology and development of the pharynx, larynx and thyroid gland. Therefore, clinicians should be aware about the triticeous cartilage.7. We also found that the degree of calcification was not related with age and gender.Ĭonclusions: Clinical importance of the triticeous cartilage is that it could be misdiagnosed with atherosclerosis in common carotid artery because the triticeous cartilage is located almost at same level as the bifurcation of the common carotid artery. The prevalence of the triticeous cartilage was higher in men than in women. Results: According to our results, triticeous cartilage presents common in the examined population (68.1%). Shapes, calcification degrees, volumes, lengths and wideness of the triticeous cartilage were evaluated by OsiriX-Lite software. Materials and methods: We examined computed tomographic angiography images of 746 patients (368 women, 378 men) retrospectively. The aim of this study is to describe prevalence and morphological properties of the triticeous cartilage. Computed tomographic angiography is able to evaluate the triticeous cartilage with using three-dimensional images in more detail. Radiological studies indicate clinical and anatomical importance of the triticeous cartilage but these studies have limited information due to inadequate inspection method. This cartilage, located in posterior end of the thyrohyoid ligament, presents in different shapes. Background: Triticeous cartilage is a small cartilaginous component of the laryngeal skeleton.
