Enucleation (surgery)

Under enucleation (from Latin ex, " out " and nucleus " core " German words " enucleation, enucleation " ) is understood in surgery to remove a deferred or bekapselten tissue region. The surrounding tissue is not removed.

Examples are

  • Enucleation of the prostate due to severe benign prostatic hyperplasia
  • The enucleation of cysts or adenomas of the thyroid
  • Enucleation of the eyeball ( eyeball ) in otherwise intractable tumors (such as conjunctival melanoma, choroidal melanoma, retinoblastoma ), in order to avoid local spread or metastasis. Furthermore, after serious eye injuries with otherwise intractable pain. In contrast to exenteration befindliches at enucleation behind the eyeball ( retrobulbar ) connective tissue, fat and eye muscles remain in the eye socket (orbit ). An enucleation is performed usually under general anesthesia. In this case, the eyeball is replaced by a seal consisting of silicone or hydroxyapatite, and is covered by the conjunctiva tissue. At this seal four of the six eye muscles are attached, so that later adapted eye prosthesis, albeit limited, can move parallel to the remaining eye. An enucleation is also a psychological burden, which requires a corresponding psychological preparation and support for the patient in the rule.
