The thyroid gland can be simply visualized for size and palpated for texture to determine the presence of an abnormality. The thyroid gland is divided into the right and left lobes and the isthmus, and is located in front of the cricoid cartilage of the 3rd and 4th trachea. There are three degrees of enlargement of the thyroid gland. In simple terms, degree I means that the thyroid gland does not look enlarged but can be palpated; degree II means that the thyroid gland is visible and palpable but does not exceed the sternocleidomastoid muscle; and degree III means that the thyroid gland is clearly enlarged, visible and palpable, and exceeds the outer edge of the sternocleidomastoid muscle. During palpation, the patient was seated, and the examiner was located in front of the patient; the thumb of one hand applied pressure to the thyroid cartilage on one side and pushed the trachea to the opposite side, while the middle finger of the other hand pushed the lateral lobes of the thyroid forward at the posterior edge of the contralateral clavicular mastoid muscle, and the thumb palpated the anterior edge of the sternocleidomastoid muscle, and with the swallowing motion, the opposite lobes of the thyroid were palpated in the same way. When palpating, pay attention to the size and texture of the thyroid gland, whether there is pressure pain, nodules, tremor, etc., and move gently to avoid pain, cough, breath holding and other discomforts caused by too much force. Thyroid enlargement has many causes, if you find abnormalities in the thyroid gland, it is recommended to combine with thyroid function and ultrasound to further clarify the condition, and make a clear diagnosis and treatment under the guidance of the doctor.
