![]() ![]() ![]() The procedure lasted 17 minutes and the patient had no complications. An apocrine metaplasia was diagnosed, with no dysplasia, inflammation, or malignancy. After the robotic alignment, an 18G biopsy needle was coaxially inserted twice through a 17G guiding needle for tissue harvesting. Micromate™ was then gross-positioned near the predefined entry-point and remotely controlled for alignment to the surgical plan under fluoroscopic live imaging. The target point for the insertion of the biopsy needle had been defined at the distal border of the segmented lesion, to ensure tissue harvesting covered the whole lesion. The suspicious lesion was segmented, and the surgical trajectory was planned using the Xper Guide planning software. To allow an unimpeded robotic approach, a strong emphasis was given to patient positioning by using a vacuum cushion to limit potential patient motion during the procedure and ensure the extension of the neck. Interventional ProcedureĪn intra-operative 3D scan of the patient in supine position was performed using a Philips Allura Xper FD20 angiography device and fused with the pre-operative MRI scan. A homogeneous mass, potentially originated from the left parotid gland, has been incidentally found in a deep location with the scan, but was invisible under ultrasound.ġ) Homogenous mass with 27.2mm of diameter found on the MRI scan 2) The lesion was not visible under ultrasound imaging 3) Segmentation of the lesion (in purple), based on the fused intra-operative 3D scan and pre-operative MRI scan 4) Alignment of Micromate™ to the surgical plan under live imaging 5) Insertion of the guidance needle and tissue harvesting 6) Setup picture. The MRI scan showed potential nerve-vessel conflict along the trigeminal nerve. The patient was an 82-year-old female exhibiting facial pain.
