Grundlagen der Injektion mittels Soft-Tissue-Filler

ZusammenfassungInjektionen mit Soft-Tissue-Fillern, insbesondere Hyaluronsäure, gehören heute zu den beliebtesten minimal-invasiven Behandlungsmethoden der Gesichtsverjüngung. Mit zunehmendem Verständnis der anatomischen Hautstrukturen und dem Wissen über die Physiologie der Hautalterung haben sich gezielt Behandlungsstrategien und -methoden entwickelt, um Patienten nach ihren Wünschen so optimal wie möglich zu behandeln. Grundlegend können Patienten entsprechend ihrem Behandlungswunsch in die Kategorien Prophylaxe, Optimierung oder Regeneration eingeteilt werden. Der Markt an Füllpräparaten liefert für jedes Behandlungsziel geeignete Präparate. Dieser Beitrag gibt einen grundlegenden Überblick zur Gewebeaugmentation mit Füllpräparaten und gibt Anregungen, um sichere Behandlungen mit optimalem Ergebnis strukturiert zu planen und durchzuführen.

The Layered Anatomy of the Nose: An Ultrasound-Based Investigation

Background An increasing number of soft tissue filler procedures in the nasal region has been reported. Concomitant with demand, the number of complications has risen due to the difficulty in administering filler in a region where soft tissue layering is complex. Objectives To describe the layered soft tissue arrangement of the nose as it relates to the underlying arterial vasculature and to define safer zones for nasal filler enhancement. Methods A total of 60 (28 males and 32 females) study participants were investigated with respect to their layered anatomy in the midline of the nose using ultrasound imaging. The presence and extent of the layered arrangement was examined as well as the depth of the arterial vasculature. Results In the mid-nasal dorsum, a 5-layer arrangement was observed in 100% (n= 60) of all investigated cases, whereas it was found to be absent in the nasal radix and tip. The 5-layer arrangement showed an average extent of 26.7% - 67.5% in relation to nasal length. The nasal arteries coursed superficially in 91.7% of all cases in the nasal radix, in 80% in the mid-nasal dorsum, and in 98.3% in the nasal tip. Conclusions Soft tissue filler administration in the nose carries the highest risk for irreversible vision loss compared to any other facial region. The safety of soft tissue filler rhinoplasty procedures is enhanced by knowledge of the layered anatomy of the nose, the location and depth of the major nasal vasculature, and employment of maneuvers to decrease the risk of blindness.

Soft Tissue Filler Therapy and Informed Consent–A Canadian Review

Soft Tissue Filler (STF) Therapy for cosmetic facial rejuvenation is associated with known complications. The manifestation of these known complications can lead to patients commencing civil litigation actions or making complaints to provincial regulatory authorities and alleging that the practitioner failed to obtain the patient’s informed consent to the therapy. Data provided by the Canadian Medical Protective Association (CMPA) on medical-legal cases arising from the provision of STF therapy between 2005 and 2019 are presented. Select reported case law decisions from Canadian courts and regulatory bodies addressing the concept of informed consent are reviewed. Insights about the risk factors pertaining to the process of obtaining informed consent for STF therapy are presented to increase an understanding of the elements of communication and documentation needed to ensure patients are aware of the consequences of this treatment.
