[Parotid tumors: a two-year experience of Otolaryngology Department at MSS Hospital in Warsaw].

THE AIM OF THE STUDY

Tumors of the salivary glands represent about 3% of head and neck neoplasms. Most of theme--up to 80%--originate from the parotid gland. The aim of the study is to present current epidemiological data, most frequent complains, our surgical technique, histopathological diagnosis, complications rate and follow-up.

MATERIAL AND METHODS

Retrospective analysis of 100 patients, operated at our department from 01.2007 to 03.2009, was performed. We analyzed the age, sex, symptoms of the dissease, histopathological findings, complications and follow-up. All of the patients had ultrasound examination prior to operation to estimate the spread and the type of the tumor. In doubtful cases the ultrasound-guided fine-needle aspiration for biopsy and cytology, computer tomography and magnetic resonance were performed.

RESULTS

The frequency of incidence of benign tumours was 90% and the most frequent histopathological diagnosis was pleomorphic adenoma (49%) and adenolymphoma (42%). By 6% of our patients malignant neoplasms were developed and tumours of non-neoplastic origin by 4% of theme. The most frequent complication was sensory deficit about the cheek and ear (35%), temporary facial nerve paresis (5%), hematoma (1%), salivary fistula (1%).

CONCLUSION

Superficial and total parotidectomy are safe procedures of treatment in case of salivary gland tumors. Using the microscope during parotidectomy is extremely useful in order to preserve the continuity of the facial nerve branches.
