Benign tumors account for 80% of parotid salivary gland tumors, early diagnosis and effective treatment will contribute to reducing complications of surgery. Objective: To evalutate surgical results of benign parotid tumors on facial paralysis and other complications. Research Methodology: including 51 patients with benign parotid salivary gland tumors at Hue University of Medicine and Pharmacy Hospital from June 2019 to October 2021 were operated on and monitored for facial paralysis after 1 week, 1 month, 3 months, and 6 months according to the House-Brackmann facial nerve grading system and noted other complications. Results: Pleomorphic adenoma and Warthin tumors are the two most common types of benign tumors. The rate of facial paralysis at the time points after 1 week, 1 month, 3 months, and 6 months gradually decreased by 56.9%, 35.3%, 19.6%, 0%, respectively. Most temporary facial paralysis grade II (mild) and grade III (moderate) (classification of House - Brackmann). The surgical method was significantly related to facial paralysis (p < 0.05). Other complications such as numbness around the ear, hemorrhage, sialocele, salivary fistula, depression of facial contour, bad scars. Nevertheless, no cases of tumor recurrence and Frey’s syndrome were recorded after 6 months. Conclusion: Surgery is an effective and safe treatment for benign parotid salivary gland tumors. Facial paralysis accounts for a high incidence after surgery, but it will fully recover after 6 months. Choosing the appropriate treatment method helps to minimize complications and recurrence after surgery of parotid salivary gland tumors.
