[The clinical assessment of regional resection in the benign tumor of parotid gland].

Regional resection in the parotid gland tumor was less invasive, the incidences in the most complications were in consistent with superficial lobe total resection, and it was helpful in preventing the occurrence of Frey syndrome. Although regional resection conserved more parotid gland tissue so that the more conserved gland function and it also did not increase the incidence of sialosyrinx, the operated region effusion was significantly increased. If the operated region effusion was not discovered and handled, there would be a risk of sialosyrinx.
