A total of 268 patients were treated for parotid gland lesions at
department of Head and Neck Surgery of Latvian Oncological Center
between 1996 and 2000, and the results were analyzed retro- spectively.
The objective was to analyze the incidence and factors associated with
facial nerve dysfunction after different types of parotidectomies with
facial nerve dissection and to compare the changing attitudes towards
the pathology and surgical treatment in order to better define
prevention and management of pleomorphic adenoma recurrences. Limited
superficial parotidectomy was the commonest operation performed in 143
patients. Other procedures were complete superficial pa- rotidectomy in
11%, total radical surgery in 10 patients and enucleation in 20
patients. Neck node dissection was done in 9 patients. In 4 patients
(6%) paresis was observed after limited superficial parotidectomy, in 10
patients (16%) after complete superficial parotidectomy, in 18 cases
(28%) after near – total (subtotal) parotidectomy and in 32 patients
(50%) after total parotidectomy. Recurences after the surgical treatment
of benign diseases were observed in 12 patients (5.2%). Overall 5-year
survival for all stages and histologic types was 58 %.
