Comparing Analyses of Parotid Mixed Tumors Surgical Methods Considering the Tumor Size and Localization

Levan Ramishvili, Konsantine Mardaleishvili

According to received results, it could be concluded, bigger is the tumor size, higher is the incidence of recurrence after the enucleation and it ranges in 29,2%-83,3%, averagely - 56,3%. This indicator after the parotid gland subtotal resection with the sparing of facial nerve is - 3,4%-12,5%, averagely - 7,9%. Analogous tendency is in this group too, particularly, bigger is the tumor size, higher is the incidence of recurrence. Considering the tumor localization and type of conducted surgery, the incidence of recurrence after the enucleation ranges in 33.3%-66.7%, averagely - 50%. The highest incidence of recurrence is noted in case of tumor corpus localization (6,7%). The incidence of recurrence after the parotid gland subtotal resection with facial nerve sparing ranges in 4.8%-9.4%, averagely - 7,1% and the highest incidence of recurrence is found in case of tumor lower pole localization (9,4%). In the group of patients with tumor sizes less than 3 cm and lower pole localization, who were done the parotid gland marginal resection, no cases of recurrence was registered. In such cases this volume of surgery could be regarded as the best method.
