Brief Summary

The botulinum toxin was first identified in the late 19th century(1). With its 40 different subtype this toxin is produced mainly by the gram positive anaerobic bacteria Clostridium Botulinum(2). This neurotoxin has great affinity to the neuro muscular junction preventing neurotransmitter release in the synaptic space of acetylcholine(3). The first clinical use was reported by Alan Scott in 1980(4). The most commonly used subtype is toxin A commercially found as BOTOX (onabotulinumtoxinA, Allergan, approved by FDA in 1989), Dysport (abobotulinumtoxinA, Medicis, approved by FDA in 2009) and Xeomin (incobotulinumtoxinA, Merz, approved by FDA in 2010). As for other commercial toxins botulinum neurotoxin serotype B product (MYOBLOC™). Neurotoxin Blast generally 12-15 weeks compared to 3-6 month for neurotoxin A. the FDA approved its use for strabismus in 1989(5), blepharospasm and hemifacial spasm in 1990(6,7), cervical dystonia in 2000(8), glabella in 2000, hyperhidrosis in 2004(9), chronic migrane and detrusor overactiviy in 2014. Other off-label uses have emerged like lanyngeal dysponia, chronic pain etc… (10). Multiple studies with a reduced number of patients have aimed to quantify the effect of botulinum toxin on brow higth. Some studies used injections only to the lateral part of the orbicularis,while others added a corrugator injection. We aimed in this study to compare a known techniques in brow lifting and associanting that with 2 frontalis injection techniques. The main objective is to evaluate the shape of the brow and the elevation in multiple brow landmarks before and after the injection and to see if the frontalis botulinum bloc causes brow ptosis

Outcome Measures

Primary Outcomes (1)

  • Objective assessment

    Objective assessment will be done on anteroposterior views of pre-and-post injection photographs. The mid pupillary line will be drawn and the eyebrow vertical height will be measured from this line to the upper border of the brow at seven horizontal points: the most medial aspect of the eyebrow, medial canthus, and medial limbus, mid pupil, lateral limbus, lateral canthus, and most lateral eyebrow.

    2 weeks

Study Arms (3)

v shape

EXPERIMENTAL

Technique 1Lateral orbicularis and corrugator injections: 5 equally spaced injections will be placed intramuscularly into the orbicularis under the lateral eyebrow starting lateral to the level of the lateral limbus and extending to the level of the inferior orbital rim. In addition, 2 injections will be placed 1cm apart into the corrugator starting at the medial brow and extending laterally. Then 5 equally spaced injections, in a V pattern will be placed in the frontalis. The first injection between the medial brows, 2 injection 1cm below the hairline at the level of the lateral canthus and one injection equidistant to medial and lateral injection.

Drug: Abobotulinum toxin A

middle frontalis

EXPERIMENTAL

: Lateral orbicularis and corrugator injections: 5 equally spaced injections will be placed intramuscularly into the orbicularis under the lateral eyebrow starting lateral to the level of the lateral limbus and extending to the level of the inferior orbital rim. In addition, 2 injections will be placed 1cm apart into the corrugator starting at the medial brow and extending laterally. Then 5 equally spaced injections, in a straight pattern will be placed in the frontalis. One injection in the middle of the forehead, one on the same level of the lateral canthus and one between them.

Drug: Abobotulinum toxin A

high frontalis

EXPERIMENTAL

: Lateral orbicularis and corrugator injections: 5 equally spaced injections will be placed intramuscularly into the orbicularis under the lateral eyebrow starting lateral to the level of the lateral limbus and extending to the level of the inferior orbital rim. In addition, 2 injections will be placed 1cm apart into the corrugator starting at the medial brow and extending laterally.Then 5 equally spaced injections, in a straight pattern 1 cm below the hairline will be placed in the frontalis. One injection in the middle of the forehead, one on the same level of the lateral canthus and one between them.

Drug: Abobotulinum toxin A

Interventions

The purpose of this study is to describe two safe and reproducible techniques upper face botulinum toxin injection. It will also describe the effect of both techniques on the eyebrow shape and height using quantitative, objective measurements and subjective scales
