| Sumario: | Objective. To assess the effect of neodymium laser radiation on the recurrence rate and continued growth of primary extramedullary tu-
mors on the basis of clinical data obtained in the long-term follow-up period in operated patients with extramedullary tumors.
Material and Methods. The long-term results of surgical treatment of two groups of patients (n = 412) with primary extramedullary tu-
mors operated on from 1998 to 2014 were studied and systematized. Patients of comparison group (n = 277; 67.2 %) underwent removal
of tumors using standard microsurgical techniques, and the neoplasms in patients of the study group (n = 135; 32.8 %) were removed
with additionally used neodymium (Nd:YAG) laser.
Results. The use of the developed laser technologies for the resection of extramedullary intracanal primary tumors made it possible to re-
liably reduce the relative number of recurrence and continued growth from 11.1 % to 1.2% compared with patients treated with standard
surgery methods. The proportion of recurrences was 3.5 %, all of them were detected only in the group with the classical technique of tu-
mor resection (p <0.01).
Conclusion. The use of a neodymium laser as an additional technology to the classical microsurgical resection of extramedullary tumors
is effective for the prevention of their recurrence and continued growth. |
