Comparison of surgical techniques for benign parotid tumours: a multicentre retrospective study

This study aimed to compare the outcomes of three surgical techniques for the treatment of patients with benign parotid tumours: superficial parotidectomy (SP; group 1), partial superficial parotidectomy (PSP; group 2), and ultrasonic scalpel-assisted minimal extracapsular dissection (US-MECD; group 3). Groups 1 and 2 received the conventional surgical technique, while group 3 underwent surgery with an ultrasonic scalpel. A total of 281 patients treated during 2012–2016 were included: 98 in group 1, 91 in group 2, and 92 in group 3.
