Introduction. The work is actual due to the need to reduce the number of complications after enucleation of the eyeball during the intra- and postoperative period.
The purpose of the study. To develop the eyeball enucleation method using the high-frequency electric welding of biological tissue in order to reduce the risk of complications.
Materials and methods. Investigations were carried out on 20 rabbits, of which eight (study group) had enucleation of the eyeball using electric welding and in 8 control animals enucleation was performed according to standard procedures. Histomorphological study of conjunctiva and optic nerve was conducted after exposure electric welding. 59 patients with uveal melanoma, who were subjected to enucleation with the help of high frequency electric welding, have been investigated. The control group consisted of 20 patients with uveal melanoma, who were subjected to enucleation by the usual methods.
Results. The obtained results have shown that the use of high frequency welding for eye enuсlеation allows avoiding bleeding when muscles and neurovascular fascicle are crossed, to reach the necessary fixation of muscles to tenon capsule and the stable connection of conjunctive margins with each other without the use of any sutural material. The use of the given method reduces not only the time of surgery (in average by 6.6 minutes). Histological studies have shown that when using the electric welding for closing the wound is the result of deposition of fibrin with subsequent epithelization surface fibrotization of subepithelial tissue, which contributes to an earlier onset of the reparative processes in the tissue.
Conclusion. The clinical and histological studies showed benefit enucleation technique using the electric welding compared with the conventional method.
