Patient characteristics
The study included 28 surgically resected patients with prestyloid PPS
tumors. Between 2015 and 2017, 14 patients were treated with a lateral
approach. Between 2018 and 2020, 14 were treated with a medial approach.
Thirteen tumors (46.4%) originated in the deep lobe of the parotid
gland. Seventeen (60.7%) were benign. Patient and tumor characteristics
are shown in Table 1.
