The pathologic basis of partial parotidectomy in parotid pleomorphic adenoma treatment / 华西口腔医学杂志

ABSTRACT

<p><b>OBJECTIVE</b>The purpose of this study was to offer pathological reasons for partial parotidectomy adopted in parotid pleomorphic adenoma treatment.</p><p><b>METHODS</b>Continuous slices from 25 cases of primary parotid pleomorphic adenoma were carefully examined and the extra-envelope infiltration, the budding and the primary multi-center were measured and recorded.</p><p><b>RESULTS</b>The range of extra-envelope infiltration and budding was limited in 0.09-0.285 mm out of tumor capsules, which was far less than the safe boundary(1 cm) of the partial parotidectomy. Two cases with multi-centers were found, but all the centers were aggregated together and encapsulated in a united envelope.</p><p><b>CONCLUSION</b>Partial parotid parotidectomy is a safe method and can remove the tumor completely in parotid plemorphic adenoma treatment.</p>
