Robotic sialoadenectomy of the submandibular gland via a modified face-lift approach

The purpose of this study was to describe and analyse the advantages and disadvantages of submandibular gland (SMG) resection using a robotic surgical system through a modified face-lift approach. The authors performed robotic sialoadenectomy of the SMG on 5 patients using the da Vinci robot system through a modified face-lift approach. Three robotic arms were inserted through a modified face-lift incision; a face-down 30-degree endoscopic arm and two operative arms. The right arm was equipped with a harmonic scalpel and the left arm with a Maryland forceps. In all patients, robotic sialoadenectomy of the SMG was completed successfully. Diagnoses were sialolithiasis in two patients, pleomophic adenoma in two patients, and ranula in one patient. The mean robotic operative time was 90.2 min (range 62-185 min) and that for setting the robotic system was 8.2 min (range 5-15 min). No significant intra-operative or postoperative complications were observed. All patients were satisfied with the outcome and especially the cosmetic results at their last follow-up visit. In the authors opinion robotic sialoadenectomy of the SMG is technically feasible and secures a better cosmetic outcome than endoscopic submandibular resection.
