Abstract

Introduction: Different approaches have been described for botulinum toxin (BTX-A) injections for face rejuvenation. Most techniques are based on the experience of the injecting physician and his/her learning curve. We describe a simplified approach to achieve accurate reproducible symmetric results with physicians of variable experience levels. Aims: To study the outcome and complications with the use of botulinum toxin injections for face rejuvenation using a precise measurement technique. Materials and Methods: This is case series includes 320 patients who underwent BTX-A injections for face rejuvenation. Injections sites were predetermined by tape measurements and distances decided upon special needs of the patient e.g. required position of eye brows. Results: No complications occurred apart from elevated lateral eyebrows in 7 (2%) patients. Retouching was needed in 26 patients (8%); 7 (2%) to lower eyebrows and 19 (6%) to deal with remaining lines Discussion: Adverse effects, though rare, are frequently related to the site or asymmetry of BTX-A injection. Even the most experienced eye cannot act as an accurate measurement device that would place injections at exactly symmetrical positions on both sides of the face. We describe a simplified approach to achieve accurate reproducible results with physicians of variable experience levels. Conclusion: Measured BTX-A injection technique is a simplified structured approach that is safe and aims at obtaining safe symmetric results.
