La tomografía computarizada es el estudio Gold standard para complementar a la endoscopia en el estudio de patologías laríngeas. Por lo tanto, se debe tener conocimiento de la anatomía normal de la laringe. En el presente trabajo se analizaron 26 tomografías de pacientes que acudieron al Servicio de Imágenes del Hospital de Clínicas sin patología laríngea. Se lograron identificar las características anatómicas radiológicas de la laringe buscadas en cada una de ellas. Siendo las características buscadas: Calcificación cartílagos laríngeos, Altura cartílago tiroideo, Distancia tiro-aritenoidea, Distancia interaritenoidea, Altura y diámetro del espacio preepiglótico.
Introduction: Computed tomography is the Gold standard study to complement endoscopy in the study of laryngeal pathologies. Therefore, knowledge of the normal anatomy of the larynx is required. Methodology: A retrospective cross-sectional descriptive observational study was carried out. Data were collected through tomographic analysis, 26 tomographies of patients who attended the Imaging Service of the Hospital de Clínicas without laryngeal pathology were analyzed. The variables investigated were tomographic characteristics such as: laryngeal cartilage calcification, thyroid cartilage height, thyro-arytenoid distance, interarytenoid distance, height and diameter of the pre-epiglottic space. Results: Each of the radiological anatomical characteristics sought were identified. In addition, the corresponding measurements were taken, detailing the average of each of the measurements and classifying them by sex. The average thyroid cartilage height in men was 28.05±1.2 mm and in women was 27.8±0.92 mm, for the thyro-arytenoid distance in men was 12.3±1.3 and in women 10.97±0.95 mm, for the transverse diameter of the thyroid cartilage in men was 16.63±1.58 mm and in women 17.96±1. 11 mm.Conclusions: The averages of the measurements taken were higher in men except for the transverse diameter of the thyroid cartilage. The prevalence of laryngeal cartilage calcification was 54% of the patients studied
