Swelling of chin and neck

Because the chin and neck are close to each other, and the neck is densely populated with lymph nodes. When the lymph nodes are affected by inflammation, it causes the lymph nodes to swell, which in turn causes the chin to swell. However, there are many reasons that can cause swelling of the chin and neck, such as submandibular gland inflammation, enlarged thyroid gland, etc. Of course there are not only these types, there are others. The editor introduces these types here because they are more common. What are the causes of swelling in the chin and neck?

1. Submandibular gland inflammation

Submandibular gland inflammation refers to retrograde infection of the submandibular gland caused by stenosis or obstruction of the submandibular gland duct. It is mostly chronic but can also be acute. The main clinical manifestations are submandibular gland enlargement, pain, and discharge of purulent secretions. Submandibular gland duct obstruction or stenosis caused by various reasons, such as salivary stones, foreign bodies in the duct, scar contracture after injury, etc., lead to poor saliva excretion and retrograde infection of oral bacteria.

2. Lymphadenitis

Lymphadenitis is a nonspecific inflammation caused by acute or chronic inflammation of the drainage area of ​​the lymph nodes. For example, infection of the upper limbs, breasts, chest wall, back and abdominal wall above the navel causes axillary lymphadenitis; infection of the lower limbs, abdominal wall below the navel, perineum and buttocks can cause inguinal lymphadenitis; infection of the head, face, mouth, neck and shoulders causes submandibular and cervical lymphadenitis. Depending on the onset and duration of the disease, lymphadenitis can be divided into acute and chronic lymphadenitis. The pathogens are often Staphylococcus aureus and hemolytic Streptococci.

3. Enlarged thyroid gland

Simple goiter is a goiter with normal thyroid function. It is a compensatory goiter caused by iodine deficiency, goitrogenic substances or related enzyme defects, and is not accompanied by obvious hyperthyroidism or hypothyroidism. It is caused by iodine deficiency, goitrogenic substances or related enzyme deficiencies.
