A comparative evaluation of landmark versus modified technique of superficial cervical plexus nerve block in the maxillofacial surgical practice.
Trial report in Oral and maxillofacial surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThis 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.
methodsA 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.
resultsThe 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.
conclusionIn 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. CLINICAL TRIAL NUMBER: Not applicable.
