This study aims to compare two techniques for administering superficial cervical plexus block (SCPB) in maxillofacial surgery: the landmark technique and the modified technique proposed by Hadzic. The research explores whether the modified technique improves precision, accelerates anesthetic onset, and enhances patient outcomes.
A prospective, single-blinded, randomized clinical study was conducted on 35 patients undergoing maxillofacial surgical procedures at the Goa Dental College and Hospital. Patients were divided into two groups: Group A received SCPB using the landmark technique, and Group B received the modified technique. Both groups underwent additional inferior alveolar and buccal nerve blocks. Key variables measured included time to anesthetic onset, pain levels using the visual analogue scale (VAS), patient comfort, and intraoperative anesthetic requirements. Data were analyzed using SPSS version 22, employing the Mann-Whitney U test and Wilcoxon signed-rank test.
The modified technique demonstrated a significantly shorter mean onset time of anesthesia (4.66 ± 1.27 min) compared to the landmark method (11.72 ± 3.78 min; p < 0.001). Postoperative pain scores after 10 min were significantly lower in the modified group (p < 0.001). Both groups reported high patient comfort, with minimal complications observed.
In conclusion, the superficial cervical plexus block is safe and effective for oral and maxillofacial surgeries, providing good anesthesia for the jaw and neck. While generally sufficient, deeper anesthesia may be required for some procedures. Combined with a mandibular nerve block, it offers a reliable alternative to general anesthesia. However, a larger, more diverse sample is needed to evaluate its efficacy across procedures.

本研究旨在比较颌面外科中两种实施颈浅丛阻滞（SCPB）的技术：标志性技术和由哈齐克提出的改良技术。该研究探讨改良技术是否能提高精准度、加快麻醉起效并改善患者预后。
在果阿牙科学院和医院对35例接受颌面外科手术的患者进行了一项前瞻性、单盲、随机临床研究。患者被分为两组：A组采用标志性技术接受SCPB，B组采用改良技术。两组均接受额外的下牙槽神经和颊神经阻滞。测量的关键变量包括麻醉起效时间、使用视觉模拟量表（VAS）的疼痛程度、患者舒适度和术中麻醉需求。使用SPSS 22版软件进行数据分析，采用曼-惠特尼U检验和威尔科克森符号秩检验。
与标志性技术（11.72±3.78分钟）相比，改良技术的平均麻醉起效时间显著缩短（4.66±1.27分钟；p<0.001）。改良组术后10分钟的疼痛评分显著更低（p<0.001）。两组患者的舒适度均较高，观察到的并发症极少。
总之，颈浅丛阻滞在口腔颌面外科手术中安全有效，可为颌面部和颈部提供良好的麻醉效果。虽然通常足够，但某些手术可能需要更深的麻醉。与下颌神经阻滞联合使用时，它为全身麻醉提供了一种可靠的替代方案。然而，需要更大、更多样化的样本才能评估其在各种手术中的疗效。
