Abstract
A retrospective analysis was made in 40 patients who underwent the examination and treatment in Dmitry Rogachev National Research Center from January 2014 to July 2017. Median age at the time of surgery was 7 years (range 4 m.–18 years). All patients underwent a comprehensive examination to determine the operation type. Precision neurolysis and facial nerve preservation were carried out in all cases of the absence of macroscopic invasion of the tumor into nerve. Facial nerve monitoring during parotidectomy was used in 45% (n = 18) patients. Follow-up period varied between 3 months and 3.5 years. There was no recurrences. Frequency of immediate postoperative facial nerve paresis was 27.5% (n = 11), from which only 2,5% (n = 1) was permanent paresis. Type of surgery was the only one risk factor of postoperative facial nerve dysfunction. Thus, age, reoperation, closely spaced tumor, operating time and malignant tumors were not risk factors of intraoperative facial nerve injury. Nerve-preserving surgery showed its effectiveness, allowing the functional state of the facial nerve to be preserved without incidental injury to the radical removal of the neoplasm of the parotid chewing area especially important in childhood and adolescence.
