Aim To investigate an incidence of recurrence of pleomorphicadenoma of the parotid gland in relation to the choice of surgicalprocedure.Methods All patients with a diagnosis of pleomorphic adenoma ofparotid gland who underwent surgery at the Department of MaxillofacialSurgery (MFS) of the Clinical Center of the Universityof Sarajevo (CCU), Bosnia and Herzegovina, in the period 01January 1992 – 31 December 2010 were included in the study.The incidence of recurrence and complications in relation to thechoice of surgical procedure (enucleation, excision of the tumor,superficial parotidectomy and total parotidectomy) as well as thechoice of diagnostic procedures were compared. For all variablesmeasured the arithmetic mean (x), standard deviation (SD), thecorrelation coefficient (r), and χ 2 test were used.Results A total of 81 operations were performed on 60 patients.The highest recurrence rate was after enucleation (88.9%), thenafter excision (46.9%), and the least after superficial (4%) and totalparotidectomy (0%). The highest number of complications wasnoted after the surgery of recurrence (8.3%), because it was difficultto preserve facial nerve in the previously treated area.Conclusion Both total or superficial parotidectomy were optimalsurgical procedures which, if applied at the first surgery of pleomorphicadenoma, provided almost 100% certainty of healing.All subsequent surgeries carry a higher risk of complications, e.g.severe lesion of facial nerve.
