Amniotic Membrane as a Biologically Active Scaffold in Septal Perforation Repair: An Experimental Rabbit Study.
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
backgroundTo investigate the effect of amniotic membrane (AM), used alone or in combination with fascia lata (FL), on septal perforation healing in a rabbit model and to assess its potential as a biologically active scaffold for septal reconstruction.
methodsEighteen rabbits were randomized into three groups (FL, AM, and AM+FL). A standardized 5-mm full-thickness perforation was created in the anterior cartilaginous septum. Grafts were placed in a submucoperichondrial plane and secured with sutures. Animals were followed for 4 weeks. Primary outcome was complete perforation closure. Secondary outcomes included percentage reduction in perforation size and histopathologic healing parameters. Residual perforation size was quantified using digital image analysis, and histologic assessment was performed by a blinded histologist.
resultsSixteen rabbits completed follow-up. The AM+FL group demonstrated the greatest mean reduction in perforation size, whereas complete closure was observed in two animals in the AM group and one in the AM+FL group. Closure outcomes differed significantly between the FL and AM+FL groups (p=0.028). Histopathologic analysis showed significantly reduced epithelial and cartilage degeneration, acute inflammation, fibrosis, granulation tissue formation, and collagen deposition in AM-treated groups compared with FL alone (p<0.05). Chronic inflammation and regenerative parameters did not differ significantly.
conclusionAmniotic membrane, particularly when used as a biologically active scaffold with fascia lata, was associated with improved histopathologic healing parameters in this experimental model. These findings suggest that amniotic membrane may have potential translational relevance as an adjunct in septal perforation repair, although further experimental and clinical studies are required.
