Objective:
The purpose of this study was to offer pathological reasons for partial parotidectomy adopted in parotid pleomorphic adenoma treatment.
Methods:
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.
Results:
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.
Conclusion:
Partial parotid parotidectomy is a safe method and can remove the tumor completely in parotid plemorphic adenoma treatment.
