title: Evolution in technique: use of hyalurostructure for lips rejuvenation as an alternative to needle injection without troncular anesthesia.
abstract: OBJECTIVE
  To enhance lips ageing rejuvenation with specific microcannula and hyaluronic acid.
  
  
  METHODS
  Clinical review was conducted from December 2010 to December 2011 among 46 patients complaining of predictable changes on lips and perioral region such as deficiency in contour definition, volume and projection. Lips rejuvenation injections were made using the hyalurostructure technique.
  
  
  RESULTS
  Forty-two patients (92%) with a 6-month follow-up were satisfied or very satisfied with the aesthetic results after the hyalurostructure of the lips and the perioral region rejuvenation. The use of the specially designed cannula led to fewer complications. We noticed 40 oedemas (87%) that appeared 24-48 h after the injection and seven patients (15.2%) with haematomas. We noted fewer surface irregularities and a better distribution of the product. Patients' records showed the procedure was painless.
  
  
  CONCLUSIONS
  The hyalurostructure technique reduces the number of punctures compared to that of the conventional method. The microcannula's blunt tip reduces the risks of intravascular injection of the substance and of reach and disruption of the key structures like vessels and nerves. Results revealed that the hyalurostructure used for lips rejuvenation and helps to maintain a natural effect and avoids pain.
