Outcomes of Inverted Tympanomeatal Flap Elevation for Large Anterior Tympanic Membrane Perforations in Narrow External Auditory Canals.
Article in Laryngoscope investigative otolaryngology, 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 and Objective: Anterior tympanic membrane perforations-particularly in patients with a narrow external auditory canal-remain technically challenging due to limited visualization and inadequate anterior support. The inverted tympanomeatal flap technique has been proposed to address these issues, but evidence is limited. This study aimed to evaluate its anatomical and functional outcomes in large anterior perforations treated with endoscopic transcanal tympanoplasty. Methods: This retrospective single-surgeon study included 70 patients with large anterior perforations and ≥ 20% anterior quadrant non-visualization. All underwent standardized audiometry and at least 6 months of follow-up. Outcomes were graft success, complications, and hearing improvement. Analyses included audiometric comparisons, logistic regression, and ROC curves to identify predictors of graft failure. Results: The graft success rate was 95.7% (67/70). Mean ABG improved from 23.44 ± 10.95 dB preoperatively to 13.52 ± 8.86 dB postoperatively ( Conclusion: In conclusion, inverted tympanomeatal flap elevation showed favorable graft success and hearing improvement in challenging anterior perforations with narrow canals. However, due to the retrospective single-surgeon design and absence of a control group, these results should be interpreted cautiously. Larger prospective studies are needed to validate its effectiveness. Level of Evidence: 4.
