Abstract

Abstract: The authors report their experience regarding parotidectomy performed under a three-dimensional-high-definition (3D-HD) exoscope, with the aim of evaluating its effectiveness in parotid surgery. This is a prospective study on nine patients treated by the same surgeon. All patients underwent parotidectomy for extrafacial primary tumours without preoperative involvement of the skin or of the facial nerve from March 2019 to June 2019 with the use of a 3D-HD exoscope. Magnification was variable from 8x to 30x with direct vision supplied by a 3D monitor. Six men and three women, mean (range) age 47.8 (19-74) years underwent parotidectomy. No patient experienced postoperative complications or definitive facial palsy. The mean (range) time of surgery was 149.4 (115 - 210) minutes. The 3D exoscope represents a valid alternative to the operative microscope or surgical loupe for parotid surgery. It is a light instrument allowing for precise surgical dissection of the parotid region by reducing the risks for iatrogenic lesions of the facial nerve using a real 3D magnification of the anatomical structures in HD. Furthermore, its use does not prolong the operative time and shows high potential for training and educational purposes since the operating room staff can better perceive the procedure and the surgeon's fine gestures. Although the preliminary applications show promising results, there is still a need for wider scientific validation.
