Parotidectomies in benign parotid tumours: “Sant Pau” surgical extension classification

Abstract

Introduction and goalsAt present different options co-exist for treating benign tumours of the parotid gland, which has led to some confusion about the extent of resection performed in each case. In an effort to improve this situation, we created a classification system to define the areas removed. We started using this classification in July 2006, and this article reviews its applicability and usefulness. MethodsWe analysed 44 patients who underwent surgery for clinically benign tumours of the parotid gland in our department between July 2006 and December 2008. Our classification was applied in all resections, dividing the parotid gland into five areas: I (lateral superior), II (lateral inferior), III (deep superior), IV (deep inferior), V (accessory). ResultsThe classification was easily applied and presented no practical problems in the 44 patients operated on. When analysing the areas excised in surgery, the most common surgery was lateral inferior partial parotidectomy (removal of Area II), in 47% of the cases. Lateral parotidectomy (removal of Areas I and II) was the next most frequent, with 14 cases (33%). The remaining 20% was distributed among the other options. ConclusionsOur classification system appears to be a simple, easy way to define the surgery performed in each case, which simplifies the description of the resection performed, even in unusual resections.
