Transauricular facial nerve combing for post-paralytic synkinesis and tightness: a propensity score-matched study.
Article in BMC 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
objectiveRefractory post-paralytic facial synkinesis and tightness pose a therapeutic challenge. This study aimed to assess the effectiveness and safety of transauricular facial nerve combing dissection in reducing synkinesis and tightness due to facial paralysis sequelae through retrospective propensity score-matched(PSM) cohort analysis.
methodsThe clinical data of 30 patients with sequelae of facial paralysis who underwent auricular nerve combing in the Department of Otorhinolaryngology Head and Neck Surgery, Chinese PLA General Hospital from January 2019 to December 2023 were retrospectively analyzed. The main outcome measures were the scores of the combined Movement Assessment questionnaire (SAQ) and the visual analogue scale (VAS) of facial tightness. Secondary assessments included the House-Brackmann facial nerve function grade, Sunnybrook facial nerve score, and the Patient-reported outcome scale (FaCE). The outcome indicators and adverse events were compared between the two groups before treatment and at 6, 12 and 18 months after treatment.
resultsAfter propensity score-matching (PSM), baseline characteristics were balanced (P > 0.05). At 18 months, the study group showed significantly greater improvements than the control group in SAQ score (13.9 ± 3.7 vs. 30.7 ± 5.0, P < 0.001), VAS score (2.0 ± 0.7 vs. 6.1 ± 1.4, P < 0.001), H-B grade, Sunnybrook score, and FaCE score (all P < 0.05). Adverse events in the study group were minor and transient (e.g., retroauricular numbness, swelling). No serious adverse events occurred.
conclusionTransauricular nerve combing provides durable improvements in synkinesis, tightness, facial function, and quality of life for refractory facial paralysis, with a satisfactory safety profile. SIGNIFICANCE & INNOVATION: This retrospective, propensity score-matched cohort study comprehensively assessed transauricular facial nerve combing dissection for facial paralysis sequelae. Results demonstrated significant, sustained benefits in alleviating synkinesis and tightness, restoring neurological function, and enhancing quality of life, providing robust evidence for clinical application.
