1
Tumor site.
Upper Superior: The tumor is superior to the mandibular branch of the facial nerve in the superficial lobe. Inferior: The tumor is inferior to the mandibular branch of the facial nerve in the superficial lobe. Deep: The tumor is in the deep lobe of the parotid gland.
2
Tumors.
One of the 28 patients had bilateral tumors, so the total number of tumors was 29.
3
Sex.
M: male; F: female.
4
Tumor size.
The mean and standard deviation of the maximum tumor diameter on CT imaging were calculated.
