Anatomical structure of the thyroid gland and larynx
Thyroid gland consists of two lateral lobes connected by the isthmus.
Thyroid cartilage angle is 90 degrees.
Position
Thyroid gland is normally located.
Upper poles mount to the middle of the thyroid cartilage lamina.
Lower poles mount to the 5th tracheal cartilage.
Upper border of the isthmus begins at the level of the cricothyroid ligament.
Shape
Thyroid gland is cone-shaped.
Larynx has male type of structure.
Anterior surface of the thyroid gland is concave, lateral border is S-shaped, posterior surface is straight, medial border repeats the shape of the trachea and esophagus. Right thyrotracheal angle is 75 degrees.
Size
Height of the right lobe - 54 mm, maximum width of the right lobe - 18 mm, maximum depth of the right lobe - 27 mm, depth of the isthmus - 5 mm.
Volume of the thyroid gland (according to the tomographic findings) - 17,4 ñm3.
Echostructure
of the thyroid gland is microgranular, homogenous.
Integrated optical density - 0.3487±0.2759.
