INJECTION ACCESSORIES |
A first-hand experience using the Silkann range of cannulae
I
run my own aesthetic clinic in Cork, Ireland, and have been offering a number of different treatments and procedures
since the clinic opened. Over this time, the demand for aesthetic fillers has grown significantly among my patients. Until the IMCAS meeting in Paris,
2012, I had pretty much decided that as an injector with 14 years' experience, I had more precision with a needle and that there was no need for cannulae in my practice. Previous experience and training with cannulae had convinced me that they were difficult to use, and the benefits were not clear. However, after attending a
workshop in Dublin in February 2012, given by Dr Kate Goldie, everything changed. During the workshop we decided
that my husband, who had no previous treatment should be the model. Aged 54 years, unconvinced and a somewhat sceptical, he agreed.
Dr Goldie demonstrated how a
cannula can be used effectively with facial fillers and the benefits it offers both the patient and practitioner. Four syringes of Radiesse (Merz
Aesthetics) were administered for a non-surgical facelift, and both my husband and I were converted. Both cannula and needle injections were performed on my husband’s face. The difference in outcome was striking. Where my husband was injected with a cannula there was no bruising, swelling or adverse events. The remaining areas that were injected using a sharp needle exhibited bruising and residual swelling for up to 2 weeks post-procedure. Since February 2012, I have

obviously visible adverse effects immediately post-treatment
■ Better overall outcomes ■ Increased patient satisfaction, resulting in greatly increased recommendations to friends and colleagues.
Since I began using cannulae
routinely in my practice, I have tried a number of products from different manufacturers. Most recently, I have started to use the Silkann range made by Sterimedix Ltd (UK). The range of products is extensive and the company has been manufacturing cannula products for eye surgery for over 20 years. The main benefits that their
products offer are: ■ Optimising the performance of the filler. Particular attention has been paid to port position, port geometry, and the internal diameter of the cannula itself
■ A choice of cannulae to match all fillers currently available. The Silkann range of cannulae covers sizes ranging from 18 G to 30 G, with a choice of cannula length for most gauge sizes
■ Allowing the clinician to be sure, at all times, of the position and orientation of the side port. Two
indicators have been incorporated into the design of the Silkann hub to show the orientation of the side port during injection
■ Reducing the risk of the cannula becoming detached during injection as a result of the high internal pressures exerted. The Silkann hub is designed with two features to reduce the potential for detachment during injection. A screw thread ensures a tight join between the cannula and syringe. Additionally, the hub is manufactured using polycarbonate, a material with a much higher frictional coefficient than standard polypropylene, which will reduce any likelihood of 'unscrewing' of the cannula during injection
■ Presentation of the product in such a way as to ensure that the integrity of the device is maintained in packaging, which will further enhance the overall image of the procedure and practice. I have now settled on the Silkann
cannulae for my practice, and use them exclusively for temple, mid-facial, jaw and lip treatments. My surgical colleagues also find them invaluable for use with fat transfer procedures, using the larger gauge cannulae recently introduced for that specific procedure.
