Pyramidal lobe
Conical pyramidal lobe often ascends from the isthmus or the adjacent part of either lobe (more often the left) toward the hyoid bone, to which it may be attached by a fibrous or fibromuscular band.
Levator glandulae thyroideae muscle
The fibrous band is called as – levator glandulae thyroideae muscle
Thyroidectomy
Completeness of thyroidectomy may be compromised by an overlooked pyramidal lobe particularly when it is very thin.
Thyroid cancer
In case of thyroid cancer complete removal of all thyroid tissue is mandatory because leaving cancer cells would have severe consequences
