Summary
Botulinum toxin injections at the temporal hairline effectively treat forehead wrinkles without causing eyelid ptosis. This method offers a safe alternative for supraciliary wrinkle correction.
Area of Science:
- Cosmetic dermatology
- Neuromodulation treatments
Background:
- Facial injections of botulinum toxin require caution in high-risk ptosis areas like the lateral forehead.
- The lower lateral forehead presents a particular challenge for safe and effective botulinum toxin application.
Purpose of the Study:
- To evaluate the efficacy and safety of botulinum toxin injections at the temporal hairline for supraciliary wrinkles.
- To assess a method that maintains distance from the facial danger zone associated with ptosis.
Main Methods:
- A randomized clinical trial involving 40 women was conducted.
- Two groups received botulinum toxin for frown lines, frontal lines, and lateral canthus lines.
- Group B additionally received injections at the temporal hairline for supraciliary wrinkles.
Main Results:
- A significant reduction in total and mean wrinkle numbers was observed post-injection (P < 0.01).
- No instances of ptosis were reported in either treatment group.
Conclusions:
- Botulinum toxin type A injections administered via the temporal hairline are a safe and effective method for correcting supraciliary wrinkles.
- This technique provides a viable option for cosmetic enhancement while mitigating risks associated with traditional injection sites.

01:26Directly Acting Muscle Relaxants: Dantrolene and Botulinum Toxin
Directly acting muscle relaxants like dantrolene and botulinum toxin (BoNT) have distinct mechanisms and applications. Dantrolene, a hydantoin derivative, acts on the ryanodine receptor (RYR1) in skeletal muscle cells. RYR1 are calcium channels present at the sarcoplasmic reticulum membrane. In response to excitation, they release calcium ions from the sarcoplasmic reticulum to the cytosol. Calcium promotes actin-myosin-mediated contraction of muscles.

01:14Muscles for Facial Expressions
The craniofacial muscles are a collection of approximately 20 thin skeletal muscles situated beneath the skin of the face and scalp. These muscles, primarily responsible for the vast array of human facial expressions, originate from the bones or fibrous structures of the skull and extend outwards to connect with the skin. While most skeletal muscles in the body are enveloped in thick fascia, facial muscles generally have a more delicate fascial covering, with the buccinator muscle being a...
01:31Skeletal Muscle Relaxants: Therapeutic Uses
Skeletal muscle relaxants are used to relax muscle tone and alleviate painful muscle contractions. However, the choice of skeletal muscle relaxants depends on the duration of the surgical procedure in order to minimize potential side effects. Skeletal muscle relaxants like neuromuscular blocking agents [NMBAs] are commonly employed as adjuvants alongside general anesthetics in clinical settings. NMBAs are also used to maintain controlled ventilation during surgery of the larynx or pharynx as...
01:22Botulism
Botulism is a life-threatening neuroparalytic condition caused by botulinum neurotoxin, which is produced by the bacterium Clostridium botulinum, a Gram-positive, spore-forming, obligate anaerobe.In adults, the toxin enters the body in different ways: in foodborne botulism, the preformed toxin is absorbed in the intestine. In wound botulism, spores grow in injured tissue and release the toxin into the blood. Infant botulism differs mechanistically from adult forms. In infants, botulism commonly...
01:20Muscles of the Eye
The muscles of the eye are sophisticated structures that control eye movement and focus, allowing for the precise and rapid adjustments necessary for vision. The human eye is controlled by ten muscles — six extraocular muscles, three intraocular muscles, and one primary eyelid retractor muscle.
Extraocular Muscles
The six extraocular muscles surround the eyeball and control its movements. They are responsible for a wide range of eye motions, including looking up, down, left, right, and rotating...

01:11Direct-Acting Cholinergic Agonists: Therapeutic Uses
Direct-acting cholinergic agonists have many therapeutic uses in various medical fields. Choline esters, including acetylcholine, have limited clinical utility due to their non-selectivity and short duration of action. Still, acetylcholine and carbachol are applied topically during ophthalmologic surgery to induce miosis. Pilocarpine, a muscarinic and ganglionic stimulator, effectively treats open-angle glaucoma and alleviates xerostomia and dry mouth caused by radiotherapy or Sjögren syndrome.
