Innovative Classification of M-Shaped Lips for Enhanced Refill Outcomes: A Case Series.
Article in Journal of cosmetic dermatology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundLips are crucial to facial aesthetics, with fuller lips often deemed more attractive. This preference has led to increased demand for non-surgical lip augmentation using dermal fillers. However, there is a gap in the literature regarding the identification and management of a particular anatomical variant colloquially known as "M-shaped lips", characterized by a central "M" configuration of the upper lip. This anatomical variant presents unique complexities. This study presents the first classification system for M-shaped lips to guide safer, more predictable treatments.
aimsTo introduce the first classification system for M-shaped lips, improving diagnostic accuracy, treatment strategies, and minimizing complications in cosmetic lip augmentation.
methodsA case series of nine patients aged 20-45 with M-shaped lips seeking cosmetic augmentation were treated with Aliaxin LV, a hyaluronic acid filler, in multiple sessions. The proposed classification system was based on the angle between the vertical and horizontal midlines of the lips, including three grades: mild (≤ 15°), moderate (16°-25°), and severe (> 25°). Injection techniques and filler volumes were tailored according to patient classification using needles and cannulas for precise placement.
resultsThe classification system facilitated personalized treatments, resulting in satisfactory aesthetic outcomes without significant complications. All the patients showed improved lip symmetry and volume, with no instances of filler migration or vascular complications.
conclusionsThe findings suggest that this classification system can significantly improve cosmetic results and reduce risks in treatment. Larger studies with more diverse populations and extended follow-up are needed to validate these findings.
