A Comparison Between Two Methods of Face-Lift Surgery in Nine Cadavers: SMAS (Superficial Musculo-Aponeurotic System) Versus MACS (Minimal Access Cranial Suspension)

[Change of perception of aged male attractiveness by conventional or male facelift: 3D simulation study of a new facelift concept for men]

BACKGROUND

 Facelift is now the fourth most common aesthetic procedure in men. Facial ageing is very different in men and women. Therefore, individual techniques are used since a uniform concept for the surgical facelift in men does not exist. This study aims to evaluate a gender-specific facelift concept especially developed for men.

MATERIAL AND METHODS

 Women and men (n = 10 each) were subjected to a three-dimensional face scan and a subsequent simulation of a V-shaped lift vector (standard lift) and a new facelift concept especially for men in a double T shape (male lift). In an online survey with 262 participants, the simulated as well as the unchanged images were presented and the attributes masculinity, femininity, attractiveness and youthfulness were queried. Statistical models were used to identify attributes of lifting as well as other factors and differences between the simulations.

RESULTS

 Facelift changes are generally associated with a significant improvement in the attributes of youthfulness and attractiveness compared with unchanged control faces. As expected, a male lift leads to masculinisation, while a standard lift leads to feminisation, regardless of the sex of the subjects. The male lift led to higher values for the attribute attractiveness in male subjects, as did the standard lift in female subjects. The standard lift developed for women is indeed more suitable for women and is associated with a significantly higher probability for the attribute youthfulness, whereas this is not the case in the newly introduced male lift concept.

CONCLUSION

 The new facelift concept for male patients is significantly associated with masculinity and attractiveness, while the standard lift suitable for women is associated with significantly higher evaluations of femininity and youthfulness. The results of the SIMALIFT study are the first evidence of the need for a more differentiated, gender-specific approach to facelifting.

Skin Excursion with Cannula Lipodissection and the Anatomical Implications of Superficial Musculoaponeurotic System Movement in the Tumescent Face Lift

BACKGROUND

The tumescent face lift uses the concept of subcutaneous cannula lipodissection of the neck, as opposed to wide skin undermining. Lipodissection mobilizes soft tissue while preserving perforating neurovascular branches. The purpose of this study is two-fold: (1) to compare the skin recruitment with subcutaneous lipodissection of the neck alone versus wide undermining and (2) to examine the effect of superiorly oriented superficial musculoaponeurotic system (SMAS) movement on jowl excursion in the tumescent face lift.

METHODS

A cadaveric study was performed on five fresh tissue cadavers. Postauricular skin excursion was measured following subcutaneous lipodissection and then measured again after traditional, wide undermining of the neck skin. Jowl excursion (in reference to the mandibular border) was measured following superiorly oriented SMAS excursion. An electronic force gauge was used to measure force application during measurements.

RESULTS

Cannula lipodissection resulted in a mean skin excursion of 41.9 mm. There was no significant difference in skin excursion compared to wide undermining (41.9 mm versus 42.1 mm; p = 0.785). Jowl position, in reference to the mandibular border, moved superiorly by a mean distance of 18.3 mm with vertical SMAS excursion.

CONCLUSIONS

Subcutaneous cannula lipodissection results in equivalent skin recruitment in comparison to wide undermining of the neck. A superior vector of pull on the SMAS results in vertical excursion of the jowl in reference to the mandibular border.
