The purpose of this study is to describe a safe and consistent technique for neck rejuvenation using botulinum toxin. This study will also evaluate the efficiency of the intervention and determine the patients that would benefit most.
The abobotulinumtoxinA will be used for the Nefertiti lift The abobotulinumtoxinA will be prepared by adding 2.5 cc of normal saline to a 500-unit Dysport© (Ipsen Ltd, Berks, UK) vial Preinjection frontal, oblique and lateral patient pictures will be taken (at rest and with contraction) Injection points: * A series of 4 injection points 1-2 cm apart on a horizontal line under the mandible posterior to the hypothetical line were the nasolabial fold meets the mandible * If present, injection of each platysmal band every 2 cm with 2 to 4 injection points per band (Injection of platysmal band will be done by holding the band between 2 fingers and injecting intramuscularly) For all injection points 5 units per point of abobotulinumtoxinA will be used A maximum of 125 units of abobotulinumtoxinA will be allowed for the global neck treatment Follow up will be done at 15 days for retouching or for post op pictures if no retouching is needed. if retouching is needed post injection pictures will be taken 10 days post retouching Retouching: each residual platysmal band will be reinjected every 2 cm with 2 to 4 injection points per band (Injection of platysmal band will be done by holding the band between 2 fingers and injecting intramuscularly) (5 units per point of abobotulinumtoxinA will be used) A total of 30 patients will be recruited

Platysmal bands at maximal contraction using a validated scale (4)
The assessment will be done by 2 plastic surgeons and 1 dermatologist. Pre and post injection scores will be calculated by the independent evaluators based on the photographic scale . The 3 evaluators will be blinded to the pre or post injection status of the photos No relevant prominence of platysmal bands Mild prominence of platysmal bands Moderate prominence of platysmal bands Severe prominence of platysmal bands Very severe prominence of platysmal bands

Platysmal bands at rest using a validated scale (5)
The assessment will be done by 2 plastic surgeons and 1 dermatologist. Pre and post injection scores will be calculated by the independent evaluators based on the photographic scale . The 3 evaluators will be blinded to the pre or post injection status of the photos No platsymal bands visible at rest Mild platysmal bands evident at rest. Bands do not appear along the full length of the neck. Mild platysmal bands evident along the full length of the neck at rest, less than 5 mm of elevation from the surrounding tissue. Moderate platsymal bandsvisible at rest along the full length of the neck, elevation at least 5 mm from the surrounding tissue. Severe platsymal bands along the full length of the neck at rest, elevation at least 5 mm from the surrounding tissue, with additional soft tissue ptotic banding present laterally
Time frame: 15-25 days post treatment
Mandibular definition change with maximal contraction will be assessed by a 2-point scale
The assessment of the pre-injection photos will be done by 2 plastic surgeons and 1 dermatologist Mandibular contour does not worsen with platysmal contraction Mandibular contour worsen with platysmal contraction
Time frame: 15-25 days post treatment
Investigators Global Aesthetic Improvement Scale
Improvement in Overall appearance (global neck, jowls, skin laxity, platysmal bands, mandibular contour), as assessed by the investigators using the Global Aesthetic Improvement Scale (GAIS). GAIS will be completed based on photographic assessment comparing post-treatment photos taken at day 15-25 post intervention to baseline photos, to assess overall aesthetic improvement. The GAIS is a 5-point scale (1-5) as follows: 1. Very Much Improved: optimal cosmetic results 2. Much Improved: marked improvement in appearance from initial condition but not completely optimal 3. Improved: obvious improvement in appearance from initial condition but additional treatments are advised 4. No Change: the appearance is the same as the original condition 5. Worse: the appearance is worse from the original condition
Time frame: 15-25 days post treatment
Subject Global Aesthetic Improvement Scale
Improvement in Overall appearance (global neck, jowls, skin laxity, platysmal bands, mandibular contour), as assessed by the subject using the Global Aesthetic Improvement Scale (GAIS). GAIS will be completed based on a live assessment of the subject with a mirror in hand for real time assessment and and a photographic assessment comparing post-treatment photos taken at day 15-25 post intervention to baseline photos, to assess overall aesthetic improvement. The GAIS is a 5-point scale (1-5) as follows: 1. Very Much Improved: optimal cosmetic results 2. Much Improved: marked improvement in appearance from initial condition but not completely optimal 3. Improved: obvious improvement in appearance from initial condition but additional treatments are advised 4. No Change: the appearance is the same as the original condition 5. Worse: the appearance is worse from the original condition
Time frame: 15-25 days post treatment
