Safer approach to non-surgical rhinoplasty
Objectives: 1. To compare different kinds of nonsurgical rhinoplasty.
2. To share experiences using different products and methods of injection (needle vs cannula)
3. To recommend a safer approach based on findings and differentiation of techniques.
Introduction: Nonsurgical nasal augmentation is already a popular approach in Asia in which it is marketed as safer and less downtime. It can be done thru either using dermal filler, PDO/PCL threads or combination, with and without neurotoxin. However, there are already studies stating that half of the cases of blindness associated with injecting dermal filler according to location is at the nasal area. The goal of this study is to share experiences using different products and methods of injection (needle versus cannula) for lesser risk nonsurgical augmentation.
Materials / method: A retrospective analysis using patient's records before and after photos in 380 cases from 2019 to 2023. Patients' age were 18 to 50 years old. There were 50 patients used filler alone injected by a sharp needle. Injected with cannula were 100 while
210 combinations of fillers plus PDO/PCL threads. Excluded were patients who had a history of previous rhinoplasty and lost to follow up A routine feedback satisfaction scores were asked through clinical follow up, social media, personal messages after 2- week and 6-month-period.Consent were done for the procedure and photos.
Results: For the total number of patients, there was a 97% interviewed upon follow up with satisfactory results. Only one case was observed to have upward bulge at the angular artery immediately after the injection of filler using a gauge 27 needle but hyaluronidase was immediately used.
Conclusion: Lesser risk in nonsurgical rhinoplasty can be achieved by choosing cannula over sharp needles. By combining with more threads, it can lessen the need of more dermal filler product. Using ice packs before injection can help in narrowing the vessels before injection. Overall, there is a significant patient’s aesthetic satisfaction six months after the procedure.
