PURPOSE Botulinum toxin A (Botox) is commonly used for strabismus treatment. Although other muscles atrophy after intramuscular injection with Botox, extraocular muscles (EOMs) do not. A continuous process of myonuclear addition in normal uninjured adult myofibers in rabbit EOMs was studied. In this study, the effect of Botox-induced muscle paralysis on myofiber remodeling in adult EOMs was exa...
AIM The aim was to evaluate the effect of botulinum toxin (Botox) injections as a conservative treatment for gummy smile. MATERIALS AND METHODS An experimental in vivo study was conducted at a dermatology clinic in Riyadh in January 2016. The study included 23 female patients who ranged from 20 to 50 years and were treated with Botox injections due to excessive maxillary gingival display. The...
Botulinum toxin (Botox) is an exotoxin produced from Clostridium botulinum. It works by blocking the release of acetylcholine from the cholinergic nerve end plates leading to inactivity of the muscles or glands innervated. Botox is best known for its beneficial role in facial aesthetics but recent literature has highlighted its usage in multiple non-cosmetic medical and surgical conditions. Thi...
OBJECTIVE This study was designed to establish whether a ratio of three units of Dysport is equivalent to one unit of Botox for the treatment of cervical dystonia. METHODS Patients with predominantly rotational cervical dystonia, and a minimum of four previous Botox treatments, were randomised to receive either the clinically indicated dose of Botox or three times that dose in Dysport units. ...
OBJECTIVE To determine whether injection with botulinum toxin type A (Botox; Allergan Inc, Irvine, California) reconstituted with preservative-free saline (0.9% isotonic sodium chloride) after 2-week cold storage in a refrigerator (4 degrees C) or freezer (-20 degrees C) is less efficacious than injection with freshly reconstituted Botox. METHODS We conducted a prospective, double-blind, rand...
UNLABELLED To the authors' knowledge, this is the first report of an allergy to onabotulinumtoxinA. The 43-year-old woman experienced severe itching after injection of Botox and Juvéderm. Results of prick and patch testing confirmed a T-cell-mediated allergy to Botox. This case can aid in the evaluation of suspected allergies to Botox. LEVEL OF EVIDENCE 5.
BACKGROUND AND PURPOSE It is recommended that Botox be used within 5 hours of reconstitution, which results in substantial quantities being discarded. This is not only uneconomic, but also inconvenient for treating patients. The aim of this study was to determine the potencies of Botox used within 2 hours of reconstitution with unpreserved saline, the same Botox refrigerated (at +4℃) 72 hours a...
OBJECTIVES Botulinum toxin type A is a potent neuromuscular paralyzing agent used in various disorders including cervical dystonia. Two preparations of botulinum toxin are now commercially available ( Dysport and Botox), but much controversy remains about their respective potencies. The aim of the study was to compare the efficacy of Botox with two different ratios of Dysport. METHODS A doubl...
OBJECTIVES The tension on a wound is one of the important factors that determine the degree of fibrosis and scar formation. We hypothesized that local botulinum toxin type A (Botox) induced paralysis of the musculature subjacent to a surgical wound with a skin defect would minimize the repetitive tensile forces on the surgical wound's edges, and this will result in a decreased fibroplastic resp...
BACKGROUND We evaluated effects of botulinum toxin A (Botox) and cast immobilization on tendon healing in a rat model. Injection of Botox into rat supraspinatus was hypothesized to reduce muscle active force and improved healing. METHODS Eighty-four supraspinatus tendons were surgically transected and repaired in 42 Sprague-Dawley rats (transosseous technique). After repair, supraspinatus mus...
