The thyroid gland is relatively resistant to infections.
An example of the gland’s resistance to
infection is the rare occurrence of infection following
thyroid surgery [14]. The rarity of thyroid
infection has been attributed to several reasons:
the high concentration of iodine within the gland,
ample supply of blood and lymphatics, and the
anatomical isolation of the gland from other neck
structures. This isolation is due to the thyroid
glands capsule and the lack of direct communication
with neighboring structures. These features
make the gland relatively resistant to infection by
direct extension from contiguous sites [1,2].
