Enucleation

from Wikipedia, the free encyclopedia

Under enucleation (from latin ex "off" and the nucleus "core", so German "coring, enucleation") is meant in the surgical removal of a defined or bekapselten tissue region. The surrounding tissue is not removed.

examples are

  • Enucleation of the prostate in severely benign prostatic hyperplasia
  • The enucleation of cysts or adenomas from the thyroid gland
  • Enucleation of the eyeball (bulb) in tumors that cannot be treated otherwise (e.g. conjunctival melanoma, choroidal melanoma , retinoblastoma ) to avoid local spread or metastasis. Furthermore, after severe eye injuries with otherwise untreatable pain. Georg Bartisch enucleated a diseased eyeball for the first time in the second half of the 16th century . In contrast to exenteration , with enucleation behind the eyeball (retrobulbar) connective tissue , fatty tissue and the eye muscles remain in the eye socket ( orbit). Enucleation is usually performed under general anesthesia. Here the eyeball is replaced by a seal made of silicone or hydroxyapatite and covered by conjunctival tissue. Four of the six eye muscles are attached to this seal so that the eye prosthesis , which will be adapted later , can move parallel to the remaining eye, albeit limited. For the patient, enucleation is usually a psychological burden that requires appropriate psychological preparation and care.
