Salivary gland tumor: Clinical, paraclinical features and the results of surgery

Abstract

Background: Salivary gland tumors are the most complex and diverse of any organ in the body. Assessing the pathological characteristics of salivary gland tumor, contributing to early diagnosis and effective treatment as well as avoiding tumor-induced complications is the focus of the study. Objective: To study clinical, paraclinical features and to evaluate the results of salivary gland tumor surgery. Materials and Methods: 41 patients with salivary gland tumor who were examined at Hue University of Medicine and Pharmacy from Jun 2019 to Jun 2020 were recorded about clinical, paraclinical and evaluated results 1 week, 1 month and 3 months after surgery. Results: Male cases were in the majority (58.5%), the mean age of patients was 52.4±12.4. Majority of the parotid gland tumor size in CT scanner encountered were between 2 and 4 cm (67.7%). Benign parotid tumors often had isodense 61.3%, clear boundaries and non - invasive surrounding. Pleomorphic adenoma was found the most often among the benign tumors at a ratio of 24.4%, followed by Warthin tumors (34.1%), with other types of benign tumors remaining. After parotid surgery, the most common complication was numbness around the earlope (77.4%), facial paralysis (41.9%), hemorrhage (29.1%), seroma (3.2%) and salivary fistula (3.2%). And after submandibular surgery, the most common complication was numbness around the wound (50%), hemorrhage (10%) and hypoglossal nerve damage was very rarely. Conclusion: FNA - Fine Needle Aspiration, Ultrasound and CT scanner were very valuable for diagnosis. Surgery was the main treatment method for salivary gland tumors.
