Transverse Cervical Nerve for Landmark-Guided Cervical Cutaneous Analgesia.
Article in Aesthetic plastic surgery, 2026. 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
backgroundNeck injections can be painful despite topical anesthesia. Blocking the transverse cervical nerve (TCN) may improve comfort, but clinicians need practical surface landmarks and attention to the external jugular vein (EJV).
methodsIn an anatomical mapping series (46 heminecks), the TCN emergence point along the posterior border of the sternocleidomastoid muscle (SCM) was recorded as a percentage of the earlobe-to-lateral clavicular SCM insertion distance (0-100%). In a pilot split-neck study (n=9), the left neck received landmark-guided TCN block with lidocaine at the mapped point (~10 mm depth) before bilateral injections; the right neck received lidocaine 5% cream, applied according to the clinic's routine protocol for 30 minutes prior to injection
resultsThe TCN emerged at a mean of 53% along the reference line. Complete cutaneous anesthesia occurred in 9/9 participants (95% CI, 66.4-100%). All participants reported lower VAS pain on the blocked side (sign test, p=0.0039). One bruise occurred (1/9; 11.1%; 95% CI, 0.3-48.2%).
conclusionsA proportional SCM landmark (~53%) provides a simple guide for landmark-based TCN block to reduce discomfort during neck injections. EJV awareness and aspiration are essential for safety.
