Calf restoration with asymmetric fat injection in polio sequelae

Botulinum Toxin Treatment for Calf Contouring Based on the Study of Combined Injection of Gastrocnemius and Soleus

BACKGROUND

Botulinum toxin is administered to paralyze the gastrocnemius muscle and reduce its size, thereby improving the calf contour and reducing the leg circumference of the calf.

OBJECTIVES

In pursuit of better efficacy, we designed a new injection protocol that targeted both the gastrocnemius and soleus. An algorithm of botulinum toxin injection for calf contouring was proposed based on the results of the study and ultrasonographic data.

METHODS

A prospective, self-controlled, double-blind study was conducted. The gastronemius muscle (GM) group (n = 17) included the patients whose gastrocnemius muscles were treated, and the GM + soleus muscle (SM) group (n = 17) included the patients who had both the gastrocnemius and soleus treated. Parameters including the maximum leg circumference and the subcutaneous fat, gastrocnemius muscle, and soleus muscle thicknesses were collected before and after injection.

RESULTS

Both GM and GM + SM injection helped improve calf contour. Although the thickness of the gastrocnemius muscle was reduced, reducing the leg circumference, the subcutaneous fat and soleus muscle had compensatory thickening after injection, especially over the long term, which may affect the efficacy. Compared with the GM group, the GM + SM group effectively reduced the tendency of the soleus muscle to thicken. Calf muscle thickness could be roughly estimated by constructing a fitting equation and measuring height, weight, and leg circumference.

CONCLUSIONS

Two injection methods achieved the effect of improving calf contour and reducing the leg circumference with equivalent patient satisfaction. The GM + SM injection group did not show any obvious extra clinical benefit when compared with the GM injection group.

Surgical Calf Augmentation Techniques: Personal Experience, Literature Review and Analysis of Complications

BACKGROUND

More attention is paid to calf appearance, both in males and females, and several surgical techniques are available. Different studies have been published over time for calf augmentation, but, to the best of our knowledge, no comprehensive literature review and complications analysis have been published.

OBJECTIVES

The aim of the study is to analyse the overall complication rate of calf augmentation surgical procedures and complication rates associated with the investigated techniques, namely subfascial implant placement, submuscular implant placement and fat grafting or lipofilling. Demographic analysis, including age and gender, is also performed.

MATERIALS AND METHODS

A literature review on the PubMed database was performed for clinical studies regarding calf augmentation surgical procedures. The authors selected and analysed 26 articles among the actual literature on this field and reported personal experience in calf augmentation surgery.

RESULTS

Twenty-six studies, published from 1993 to 2018, were included in the study for a total amount of 1498 patients, with a total of 2629 calves treated. Three different surgical techniques have been reviewed, excluding medical procedures: subfascial implant augmentation (n = 1929), submuscular implant augmentation (n = 435) and fat grafting (n = 265). The overall complication rate was 4.4883%. Calf augmentation with subfascial implants presented a total complication rate of 5.702%. The submuscular implant placement complication rate was 0.92%. Fat grafting presented a global complication rate of 1.509%.

CONCLUSIONS

Calf augmentation, with all reviewed surgical techniques, has a low rate of complications compared to other body contouring procedures, but a high rate of satisfaction among patients. Fat grafting has the lowest rate of complications, but multiple sessions are required. Specific complications of implants, such as capsular contracture, malposition or rupture, are less common compared to the use of implants for other cosmetic purposes. Procedures should always be performed by experienced plastic surgeons.

Modern trends in lipomodeling

Lipomodeling is the process of relocating autologous fat to change the shape, volume, consistency, and profile of tissues, with the aim of reconstructing, rejuvenating, and regenerating body features. There have been several important advancements in lipomodeling procedures during the last thirty years. Four clinical steps are important for the success of engraftment: fat harvesting, fat processing, fat reinjection, and preconditioning of the recipient site. With the discovery of adipose derived stem cells and dedifferentiated cells, fat cells become a major tool of regenerative medicine. This article reviews recent trends in lipomodeling trying to understand most of the issues in this field.
