The purpose of the study is
the development of indications and evaluation of the long-term results
of surgical treatment of benign tumors and dysplastic processes of the
mandible by the method of replantation of resected bone exposed to
extraorganic freezing. Material and methods. A method for the surgical
treatment of benign tumors and dysplastic processes of the mandible has
been developed. It involves resection of an afflicted by pathological
process segment of bone within healthy tissues, its mechanical
processing, freezing in liquid nitrogen followed by slow thawing, and
replantation. The evaluation of the treatment results has been carried
out on the base of clinical, radiation and functional research methods.
Long-term follow-up after surgery has been ranged from one to 25 years.
Results and discussion. Positive results of surgical treatment were
recorded in 72 patients (88,9 %). The indications for the developed
method use have been established. It was found that the reconstruction
of the mandible with a resected bone segment exposed to extraorganic
cryosurgery, eliminates the recurrence of a benign tumor, provides for
the restoration of the anatomical integrity of the jaw, and reduces the
invasiveness of the operation. Conclusion. Long-term clinical experience
has shown that mandible direct reconstruction in the surgical treatment
of benign tumors and dysplastic processes with the method of resection,
external freezing of the afflicted jaw area and its replantation is
available, simple, and highly effective and can be recommended in the
practice of medical institutions.
