Abstract:
Objective:Traditional salivary gland surgery involves incisions in the visible facial and cervical regions, leaving postoperative scars that affect cosmesis. This study aims to investigate the clinical efficacy, safety, and application value of robot-assisted endoscopic resection of benign submandibular and parotid gland lesions via a postauricular approach, while clarifying its advantageous differences compared with endoscopic surgery. Methods:Clinical data of 23 patients who underwent robot-assisted endoscopic surgery via a postauricular approach（11 parotid gland cases and 12 submandibular gland cases） from January 2017 to February 2025 were retrospectively analyzed. Meanwhile, A matched control group of patients who received postauricular endoscopic surgery during the same period was selected as the control group in a 1∶1 ratio（11 parotid gland cases and 12 submandibular gland cases）. Indicators such as operation time, intraoperative blood loss, complications, and postoperative aesthetic satisfaction scores（Numeric Satisfaction Scale, NSS） were collected and compared between the two groups. The inclusion criteria were limited to benign lesions of the parotid superficial lobe（diameter ≤5 cm, without deep lobe involvement） and benign submandibular gland lesions（diameter ≤4 cm, without extension through the mylohyoid muscle）. Results:All robot-assisted surgeries were successfully completed without conversion to open surgery. In the robot group, there were 7 male patients（mean age 39.5 years） and 16 female patients（mean age 35.9 years）. For parotid gland surgeries, the mean operation time was （114.00±38.35） minutes. For submandibular gland surgeries, the mean operation time was（140.00±30.75） minutes.Temporary facial paralysis occurred in 0 of patients after robotic submandibular gland surgery （vs.8% in the endoscopic group） and 18% after robotic parotid gland surgery （vs.27 % in the endoscopic group）,all of which resolved within 1 month, with no occurrence of salivary fistula or infection. Patients had high aesthetic satisfaction（NSS scores: 8.90±1.20 for parotid surgeries and 9.00±0.70 for submandibular surgeries）. No tumor recurrence was observed during the 8-77 month follow-up period. Conclusion:Robot-assisted endoscopic salivary gland surgery via a postauricular approach is safe and feasible. With three-dimensional high-definition visualization and precise mechanical manipulation, it outperforms traditional endoscopic surgery in reducing blood loss, lowering the risk of nerve injury, and achieving long-term cosmetic outcomes. It is particularly suitable for young patients and cases with benign lesions of the parotid superficial lobe or submandibular gland that have high aesthetic demands. However, this surgical approach is not suitable for deep parotid lobe tumors, and its long-term efficacy requires verification through large-sample studies.
