Efficacy of Ultrasound-Guided Intermediate Cervical Plexus Block by Anterior Route for Perioperative Analgesia in Robotic Thyroidectomy by Retroauricular Approach: A Case Series.

Retroauricular or facelift approach for robotic thyroidectomy involves a long incision with extensive subcutaneous dissection causing severe pain and discomfort. Multimodal analgesic regimen with inclusion of intermediate cervical plexus block by anterior route provided excellent perioperative analgesia without affecting recurrent laryngeal nerve monitoring in 10 cases. All the patients were monitored with bispectral index (maintained 40-60) and extubated on table. Median numeric pain rating scale score in 24 hours postoperatively was 3. None of the cases had any significant complications on follow-up.
