Comparisons of the Clinical Outcomes of Mandible Contouring Surgery With or Without the Use of Intraoral Drains.
Article 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
backgroundMandible contouring surgery is a common cosmetic procedure aimed at reducing the width of the lower face or correcting chin-related issues by contouring the mandible. Typically, an intraoral drain is placed during procedures involving the reduction of the mandible angle portion to mitigate seroma or hematoma formation. Despite this standard practice, anecdotal evidence suggests that the omission of drains does not significantly impact complication rates or surgical outcomes.
methodsA retrospective study was conducted to compare surgical outcomes and complication rates between patients who received intraoral drains (n = 338) and those who did not (n = 132) during mandible contouring surgery. The primary outcomes measured included the incidence of seroma, hematoma, and infection by counting the number of post-operative interventions required to address these complications. Statistical analysis was performed using chi-square tests for categorical variables. A p-value of < 0.05 was considered statistically significant.
resultsThe incidence of post-operative surgical interventions for bleeding control or hematoma evacuation in the drain group was 0.59% compared to 0% in the no-drain group (p = 0.922). Minimally invasive interventions were required in 2.37% of patients with drains and 3.03% without drains (p = 0.933). Infection rates were 1.18% in the drain group versus 0.76% in the no-drain group (p = 1.0).
conclusionThe study demonstrates no statistically significant difference in complication rates between mandible contouring surgeries performed with or without intraoral drains. These findings suggest that the routine use of drains may be unnecessary, potentially simplifying post-operative care and reducing patient discomfort.
