Introduction:
The aging process occurs in all anatomical layers of the face; therefore, rejuvenation should not be limited to the dermic signs of aging (Aesthet Surg J. 2018;38:73) The treatment with fillers in strategic points can reconstruct young anatomy, providing natural results (Aesthet Surg J. 2018;38:73). There are two instruments used for facial application of hyaluronic acid: cannula and needle. Both of them have advantages and disadvantages.
Objective:
In this study, we aim to compare the limitations of application with cannula by cutaneous ultrasound when compared to the needle by ultrasound, since some injectors suggest that one of the disadvantages would be the inability to reach certain application plans (periosteum).
Materials And Methods:
A 52-year-old female patient was treated with 22 mg/ml hyaluronic acid (Juvéderm® Voluma), guided by high-frequency ultrasound (LogicE device, Logic brand (GE Healthcare), with high-frequency linear probe (L8-L18i-RS). The left hemiface was treated with a 27G needle and the right hemiface with a 5 cm 22G cannula (SoftFil®).
Conclusion:
This study proved that, in the malar/zygomatic and the chin region, it is possible the cannula and needle reached the supraperiosteal region. In the temporal region, the cannula did not reach the supraperiosteal plane.
