Preoperative diagnosis management of PPS giant tumors should be based on imaging and upon open transoral biopsy if possible. The transparotid-intraoral approach provided adequate visibility to remove large PAs involving the prestyloid PPS.

Oxidative stress was detected in patients with BRONJ, and the GSSG/GSH ratio was the most significant OS variable found; it was a significant factor predicting the development of BRONJ.

BackgroundTo analyze the presence of salivary Epstein-Barr virus (EBV) DNA in oral squamous cell carcinoma and potentially malignant oral disorders.Material and MethodsThree groups were studied: Group 1 (12 oral squamous cell carcinomas (OSCC)), Group 2 (12 potentially malignant oral disorders (PMD)) and Group 3 (47 healthy controls). EBV DNA salivary analysis was performed by PCR.ResultsThe highest percentage of positive salivary EBV DNA corresponded to the OSCC group (58.3%), followed by the PMD group (41.7%) and the controls (40.4%). The differences between groups were not statistically significant, however (p>0.05).ConclusionsSalivary EBV DNA was more prevalent in OSCC than in PMD or the controls. Key words:EBV DNA, saliva, oral squamous cell carcinoma, oral leukoplakia.
