Procedure: Nefertiti lift
Registration Number
NCT02864511
Lead Sponsor
St Joseph University, Beirut, Lebanon
Brief Summary

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.

Detailed Description

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

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

Oral commissures at rest using a validated scale from the Summit Scale II (2)15-25 days post treatment

Secondary Outcome Measures
NameTimeMethod
Investigators Global Aesthetic Improvement Scale15-25 days post treatment

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

Patient willingness to recommend the procedure15-25 days post treatment

Patient willingness to recommend the procedure to a friend will be assessed by a simple question with a Yes or No response

Subject Global Aesthetic Improvement Scale15-25 days post treatment

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

Patient satisfaction15-25 days post treatment

Patient satisfaction will be determined by a questionnaire completed at 15-25 days post-treatment. Subjects will indicate how satisfied they are on a 4-point scale (1-4) as follow:

1. Very Satisfied

2. Satisfied

3. Dissatisfied

4. Very Dissatisfied.

Patient willingness to repeat the procedure15-25 days post treatment

Patient willingness to repeat the procedure will be assessed by a simple question with a Yes or No response

Assessment of Pain during treatmentAt the day of the procedure

Subjects' pain during the treatment will be recorded using a validated Numeric Rating Scale (0-10), with 0 representing no pain and 10 representing the worst pain possible
