Basic Injection Techniques

Treatment with injectable fillers is the procedure to put filling materials of different characters into tissue to provide volume, change contours, improve tissue quality, provide tissue strength, and give structural support. Different techniques of filler placement involve the control of injection flow, the control of aliquot size, and the deployment of fillers in a certain depth of tissue and in specific patterns. However, these arrangements of filler distribution perform like the mechanics of architecture and can have an impact on the shape of the final façade, the effect of augmentation, and how the whole moves flexibly and naturally with muscles. Basic techniques are the skills fundamental to all the variant and novel techniques; a practitioner should be thoroughly familiar with them before extrapolating them to other advanced techniques.
Optimizing Aesthetic Combination Treatments with Botulinum Toxin
Published in Yates Yen-Yu Chao, Optimizing Aesthetic Toxin Results, 2022
For filler injections, the toxin could be combined in the same area and administered after the fillers. Toxin should be directed to the muscles and deposited as close as possible to the target fibers. For filling spaces that could be restricted or potentially disturbed by muscle contractions, toxins could be applied one or two weeks before to make room for the coming fillers.

Before proceeding with injections, the planned area for filling is marked out. We use cannulas (usually 27 G) for all periorbital injections to reduce bruising/swelling and minimize complications. A small wheel of local anesthetic at the cannula insertion site is typically all that is necessary. Patients are generally instructed to be off aspirin-containing products for 7 days, and nonsteroidal anti-inflammatory drugs for 2 days, prior to periorbital injection. The vectors of cannula injection technique are shown in Figure 7.8.
The Internalized Stigma and Self-Esteem in Individuals with Alcohol and Risky Substance Use Disorder

The descriptive and correlational study was conducted in the Alcohol and Drug Addiction Research, Treatment and Education Center (AMATEM) of a Training and Research Hospital, between 10th of May – 31st of December 2021. The population of the study consisted of 233 alcohol and substance addicted patients who sought inpatient and outpatient treatment at AMATEM between these dates. All patients who met the research criteria were included in this study. Not wanting to participate in the study was an exclusion criterion. The participation criteria for the study were as follows; being diagnosed with alcohol and substance use disorder according to DSM-V criteria having gone through a withdrawal period, being between the ages of 18 and 65, being literate, and volunteering to participate in the study. The data was collected by the researcher in the interview room using face-to-face interview method. The patients were instructed to complete the Descriptive Information Form, Coopersmith Self-Esteem Inventory (CSEI), and the internalized Stigma of Mental Illness Scale (ISMI). The patients completed the forms by reading and marking the questions on each form, asking the researcher if they had any questions, and then the data collection process was completed. Filling out the forms for one patient took an average of 20 minutes.
Hyaluronic acid injection to restore the lost interproximal papilla: a systematic review

Regarding the injection technique, five studies injected the filler 2–3 mm apical to the PT [23,25–28], two of them at 2–3 mm coronal to the PT [24,30] and three at the base of the deficient papilla [29,31,33]. Two studies [26,32] performed a 3 injection-technique filling. One study [32] described a technique with 3 injections at the papilla forming an equilateral triangle with the adjacent teeth. Another 3 injection-technique was described by Bertl et al. [26]: firstly, creating a reservoir in the mucosa above the mucogingival junction, secondly injecting 2–3 mm apically to the tip of the deficient papilla and finally into the attached gingiva/mucosa just below the base of the deficient papilla. Post-operative instructions varied among 6 studies [24,25,28,31–33], being the most common recommendations no brushing within first 24 h and extreme oral hygiene after the procedure. Five studies did not specify any recommendations [23,26,27,29,30]. Details of the clinical procedures are reported in Table 3.
Injectable and adhesive hydrogels for dealing with wounds

In the field of regenerative medicine, the necessity to recognize and harness the effects of natural biomaterials in conjunction with active compounds plays a crucial role. It is important to standardize the problems posed by the multiple factors influencing tissue recovery and reconstruction and hold the recognized standards to increase the quality of effectiveness in the wound healing process. Advancements in materials science have now rendered researchers multiple methods where hydrogel formation can happen in situ through standard needles upon delivery. This matter offers an effective and convenient way for delivering therapeutics and living cells minimally invasively, filling complex tissue defects, and consequently triggering the regeneration of damaged body parts. Once achieving their missions, they can be engineered to be degradable and eventually removed from the body.
