The Blending Technique: A New Approach for Tear Trough Correction.
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
introductionThe tear trough is one of the areas that most reflects aging. The anatomy of the preseptal, premaxillary, prezygomatic and deep pyriform spaces are essential for successful planning of filler treatments. MATERIAL AND TECHNIQUE: This work analyzes the anatomic relationship between the origin of the orbital septum and the tear trough/ orbicularis retaining ligaments, and between the anatomical spaces and the cheek fat compartments, to classify patients who undergo a filler treatment for tear trough deformity. Patients are classified in 'innie' or 'outie' and blending technique is described based on this classification.
resultsA total of 38 patients were evaluated, comprising 21 females and 17 males, with a mean age of 53 years (range, 31-72 years). The mean follow-up period was 10.4 months (range, 5-22 months). All patients presented with an innie-type tear trough deformity. Prior to treatment, 76.3% of patients (n = 29) were classified as Hirmand Type II, and 23.7% (n = 9) as Type III. Following treatment, 84.2% (n = 32) of patients were rated as "very much improved" (GAIS score of 1), and 15.8% (n = 6) as "much improved" (GAIS score of 2). The mean volume of hyaluronic acid injected per unilateral tear trough was 0.35 cc (range of 0.2-0.5 cc), and for the unilateral midcheek was 0.65 cc (range of 0.5 to 2 cc). No complications were reported.
conclusionThe blending technique is an effective technique to improve the appearance of the lid-cheek junction, correcting the TT deformity and the palpebromalar groove. Patients are classified as innies or outies based on the position of the AM on the orbital bone. Innie patients are more favorable to the injection of HA in the gap between AM and ORL (preseptal space) to correct the TT groove. Outie patients benefit from the volumization and support of the DMCFP, but not from direct injection into the TT and preseptal space.
