Effect of mucosal fenestration drainage on postoperative complications following surgical extraction of mandibular third molars: a randomized controlled clinical trial.
Trial report in BMC oral health, 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
BACKGROUND: Surgical extraction of impacted mandibular third molars is frequently associated with postoperative complications. This study aimed to evaluate the efficacy of mucosal fenestration drainage-a novel technique-in improving postoperative outcomes following such extractions. METHODS: Between September 2022 and September 2023, patients requiring extraction of impacted mandibular third molars at our hospital were enrolled. Those with fully impacted teeth were randomly assigned to either a suture group (primary wound closure) or a drainage group (fenestration drainage in the posterior molar region). Patients with partially impacted teeth were included as a natural group. Postoperative reactions and complications were assessed and compared. RESULTS: A total of 120 patients were included (40 per group). Postoperative swelling was significantly reduced in the drainage group compared with the suture group on postoperative day 2. The natural group, which consisted of partially impacted teeth and was included according to impaction status, showed relatively lower swelling scores during the early postoperative period; however, this finding should be interpreted as clinical reference data rather than evidence from a randomized comparator. No statistically significant differences were observed in pain, trismus, infection, lower lip hypoesthesia, or second molar discomfort. CONCLUSION: Mucosal fenestration drainage confers a modest reduction in early postoperative swelling; however, its overall clinical benefit remains limited.
