Morphofunctional peculiarities of the effects of electric coagulator on thyroid tissue

Morphological changes in the thyroid tissue after exposure to coagulators were studied. Application of a monopolar coagulator resulted in the formation of narrow marginal coagulation necrosis on day 3, with a fibrous capsule of different thickness, and marginal sclerosis of the glandular parenchyma; inflammatory changes in the connective tissue in the resection edge persisted for 14 days. Bipolar coagulator produced the most pronounced damaging effect leaving septae up to 10 mm long penetrating into the depth of the gland and causing stubborn persistent deep and marginal sclerosis of the gland. © Springer Science+Business Media, Inc. 2005.
