Effect of Depressor Septi Transposition on Preventing Tip Droop During Smiling in Tongue-in-Groove Tip Plasty: A Randomized Controlled Trial.
Trial report in Aesthetic plastic 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
BACKGROUND AND
aimsPlunging tips caused by overactivity of the depressor septi nasi (DSN) muscle present common challenges in rhinoplasty. The tongue-in-groove (TIG) surgical technique has proven effective in correcting static tip drooping.
objectiveThis study aims to assess the effect of DSN transposition on preventing tip drooping during smiling in TIG tip plasty.
methodsThis clinical trial was conducted at a tertiary academic hospital from April 2022 to July 2024. Fifty patients with plunging tips who were undergoing septorhinoplasty were randomly assigned to two groups: TIG alone (n = 25) and TIG with DSN transposition (n = 25). The primary outcome measured was the percentage change in the tip angle between relaxed and smiling poses, evaluated through preoperative and one-year postoperative assessments. Secondary outcomes included the position of the tip, the position of the alar, tip projection, rotation, and patient satisfaction measured by the Standardized Cosmesis and Health Nasal Outcomes Survey.
resultsThe reduction in tip angle was significantly greater in both groups (TIG alone: from - 9.38 to - 5.80%, p < 0.001; TIG with DSN transposition: from - 11.57 to - 8.65%, p = 0.001). There were no significant differences between the groups in terms of tip angle (p = 0.518), tip position (p = 0.363), alar position (p = 0.239), or nasolabial angle (p = 0.287). Improvements in patient satisfaction scores were also similar between the groups (TIG alone: 15.62 ± 8.44; TIG with DSN transposition: 18.50 ± 8.64, p = 0.286).
conclusionBoth TIG and TIG combined with DSN transposition effectively reduce dynamic nasal tip drooping during smiling. DSN transposition may not lead to a significant improvement in outcomes compared to TIG alone. LEVEL OF EVIDENCE I: This journal requires that authors assign a level of evidence to each article.
