A number of anesthetic options are available for use in cutaneous fillings.The combination of calcium hydroxyapatite with lidocaine in the same syringe using the female Luer Lok connector has been recently described.An additional connector option to combine these substances, the device itself, and the details of the association are described.

Calcium hydroxylapatite is a biocompatible, non-antigenic, biodegradable, opaque material that is a viable treatment option for rejuvenating the hands by increasing their volume and reducing the visibility of blood vessels and tendons. This article describes 16 cases treated with a half syringe of calcium hydroxylapatite in the back of each hand. The results suggested that the treatment was safe, well tolerated and effective, with a high degree of satisfaction in 75% of cases and clinical improvement for up to 12 months after the injection.

INTRODUCTION: Calcium hydroxyapatite in a carboxymethylcellulose carrier gel presents unequivocal results for facial skin improvement, stimulating the collagen and elastin production. Regulatory agencies recently approved its use after scientific proof of its benefit in greater dilution.
OBJECTIVE: This study aimed to demonstrate a technical standardization to rationalize body application. Methods: This study idealized vectorized figures to apply calcium hydroxyapatite with intermediate dilution (1:4).
RESULTS AND DISCUSSION: The proposed technique makes it possible to accurately calculate the required for each patient, depending on the anatomical unit’s size to be treated and the region’s topographic characteristics. This technique’s rationale also allows homogeneous distribution, minimization of complications due to product accumulation, good tolerability by the patient and optimization of results.
CONCLUSIONS: The vectorized figures’ technical simplicity facilitates calcium hydroxyapatite application, and customizations must be made with the injector’s greatest experience.

The search for aesthetic procedures aimed at the loss of submental definition is increasing. A correct diagnosis is imperative for successful treatment and the reduction of complications. Localized adiposity, skin flaccidity, and loss of bone structure are the main findings. A treatment algorithm was discussed in this review, remembering, of course, the possibility of combined and sequential treatments for better results.
