Abstract

Background

Lips 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.

Aims

To introduce the first classification system for M-shaped lips, improving diagnostic accuracy, treatment strategies, and minimizing complications in cosmetic lip augmentation.

Methods

A 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.

Results

The 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.

Conclusions

The 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.

创新的m型唇分类提高补唇效果：一个案例系列

嘴唇对面部美学至关重要，丰满的嘴唇通常被认为更有吸引力。这种偏好导致使用真皮填充物的非手术丰唇需求增加。然而，关于识别和管理一种特殊的解剖变异，俗称“M形唇”的文献中存在空白，其特征是上唇的中心“M”形结构。这种解剖变异呈现出独特的复杂性。这项研究提出了第一个m型唇的分类系统，以指导更安全，更可预测的治疗。目的介绍首个m型唇的分类系统，以提高隆唇术的诊断准确性、治疗策略和减少并发症。方法对9例20 ~ 45岁的m型唇整形患者采用透明质酸填充剂Aliaxin LV进行多期治疗。提出的分类系统基于嘴唇垂直和水平中线之间的角度，包括三个等级：轻度（≤15°），中度（16°-25°）和严重（> 25°）。注射技术和填充体积根据患者的分类量身定制，使用针和套管进行精确放置。结果该分类系统便于个性化治疗，美观效果满意，无明显并发症。所有患者的嘴唇对称性和体积均得到改善，无填充物移位或血管并发症。结论该分类系统可显著提高美容效果，降低治疗风险。需要对更多样化的人群进行更大规模的研究和更长期的随访来验证这些发现。
