Robotic neck surgery using retroauricular approach - Experience of 60 procedures

Remote access approaches to the neck have gained attention due to cosmetic concerns with conventional cervical incisions. Their safety, reproducibility, and oncologic outcomes remain to be fully validated. We retrospectively analyzed our initial experience with retroauricular robotic neck surgery using the Da Vinci system. Thirty-two patients were included. Data collected comprised demographics, procedure type, surgical features, and oncological follow-up. Thirty-five surgeries were performed: 13 posterolateral neck dissections (levels II-V) with central (VI), 5 modified radical dissections (I-V), 5 posterolateral dissections (II-V), and 1 super-selective neck dissection (I). Twelve neck dissections were combined with thyroidectomy. Additional procedures included 4 partial thyroidectomies, 3 submandibular gland resections, 3 schwannoma resections, and 1 branchial cyst excision, totaling 60 procedures. Twenty patients had malignant disease (62.5%). Median hospital stay was 2 days (range 1 9), similar to conventional approaches. Complications included 5 temporary nerve palsies, 1 lymphatic fistula, 1 transient hypoparathyroidism, and 1 minor flap necrosis, all managed conservatively; 1 hematoma required reoperation. Conversion to a conventional approach occured in 4 cases (6.7%). No additional intraoperative or postoperative complications were observed. The mean lymph node yield was 54 in posterolateral/radical dissections and 13 in central dissections. Median follow-up of malignant cases was 41.3 months (range 18-56), with a 3-year regional control rate of 94.7%. Our experience with 60 retroauricular robotic procedures demonstrates this approach to be safe, feasible, and oncologically effective, with complication rates, hospital stay, and oncological outcomes comparable to conventional surgery.
