Abstract
Purpose:
The review of indications for surgical treatment of major salivary glands in adults hospitalized in the Department of Otorhinolaryngology, Head and Neck Surgery, Medical University of Warsaw.
Materials and methods:
The retrospective analysis was based on the 1173 postoperative histopathological examinations of the salivary glands collected over a period of 10 years (2010-2020).
Analysis included histopathological diagnosis, localization of lesions, multifocality, complete resection, lymph node involvement, as well as demographical data of sex and age.
Results:
Over half (61.38%) of all indications for surgical treatment of the salivary glands were benign tumors (n = 720) with the most common pleomorphic adenoma, which accounted for 33.5% of all cases (n = 393). The next most frequent group of diagnoses were non-neoplastic diseases of the salivary glands, 24.98% of all cases (n = 293). Malignant neoplasms of the salivary glands accounted for 13.64% of all diagnoses (n = 160). Salivary gland diseases slightly predominated among the female sex, with a particularly pronounced predominance in pleomorphic adenoma. Men, on the other hand, were treated more often for malignant neoplasms. The mean age of the patients was the lowest in the group of non-neoplastic diseases of the salivary glands. The mean age of patients with malignant neoplasms was significantly higher than in other pathologies. The largest tumors size was identified for malignant neoplasms. Diseases of the salivary glands treated surgically were most often located in the parotid gland, with the exception of non-neoplastic diseases, which most often involved the submandibular gland.
Conclusions: Surgical management in pathologies of the salivary glands applies to all types of lesions, both neoplastic and non-neoplastic diseases. Patients with particular diseases are characterized by a different structure of age, sex and location of changes.
