Management of internal nasal valve collapse after nasolabial fold augmentation with hyaluronic acid filler: A case report.
Article in JPRAS open, 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
Hyaluronic acid dermal fillers for nasolabial fold correction are generally safe, but rare complications can occur. We present the first reported case of an internal nasal valve collapse following nasolabial fold augmentation with hyaluronic acid filler in a 50-year-old woman with mild septal deviation. The patient developed unilateral nasal obstruction and noisy breathing 3 days post-injection. Examination confirmed collapse of the left internal nasal valve during deep inspiration, which resolved with lateral cheek support. Conservative management, including warm compresses, firm downward massage, and intranasal corticosteroid spray, resolved symptoms by day 20 post-procedure without the need for hyaluronidase. The aesthetic result remained satisfactory. This case highlights the importance of thorough anatomical assessment before midface filler injections and prompt recognition of unexpected functional complications. Awareness of nasal valve dynamics and careful injection technique near the pyriform aperture can help prevent such events.
