Parotid gland tumors: Surgical experience Hospital Guillermo Grant Benavente

Abstract

Introduction: Parotid gland is the most common site of salivary gland tumors, co- rresponding to 75-85% of these and 3% of all head and neck tumors. 80% of them correspond to benign tumors. Aim: To analyze the surgical experience in parotid tumors operated in the Guillermo Grant Benavente Hospital. Material and Method: Review of all patients with parotid tumors operated in the Otorhinolaryngology and Head and Neck Surgery Unit of Hospital Guillermo Grant Benavente between January 2011 and April 2016. All surgeries were performed by the same surgical team. Demographic, clinical, surgical, histological and postoperative re- sults were recorded. Results: In the period described, a total of 94 patients were operated on. 84.3% co­rresponded to benign tumors and 15.7% to malignant tumors. 62.9% corresponds to female patients and 37.1% male, representing a ratio of 1.69: 1. The incidence of transient facial paralysis was 16.1%, and of these, only one patient maintained permanent paralysis. Conclusions: Malignant tumors represented 15.7% of cases, being less than re- ported in the literature. This article presents a large series of parotid tumors treated surgically in our country, with a low associated complication rate.
