The facial muscles are controlled by the facial nerve (seventh cranial nerve), which originates at the brainstem and exits the skull below the ear where it separates into five main branches. This disease takes two forms: typical and atypical. In typical form, the twitching usually starts in the lower eyelid in orbicularis oculi muscle.
Myokymia is an involuntary, spontaneous, localized quivering of a few muscles, or bundles within a muscle, but which are insufficient to move a joint. One type is superior oblique myokymia. Myokymia is commonly used to describe an involuntary eyelid muscle contraction, typically involving the lower eyelid or less often the upper eyelid. It ...
The advantages of this flap is that there is no need to skin graft the donor site and scars are placed at the natural skin folds. This flap is used for posterior and moderate-sized anterior cheek defects. Lower eyelid ectropion should be prevented, by minimizing tension and by overcorrection and suspension of the cheek flap to the lateral ...
The palpebral branches ascend deep to the orbicularis oculi and pierce the muscle to supply the skin of the lower eyelid. The nasal branches supply the skin of the side of the nose and the moveable part of the nasal septum. The superior labial branches descend deep to the levator labii superioris to supply the skin of the anterior cheek and ...
Fasciculations arise as a result of spontaneous depolarization of a lower motor neuron leading to the synchronous contraction of all the skeletal muscle fibers within a single motor unit. An example of normal spontaneous depolarization is the constant contractions of cardiac muscle, causing the heart to beat. Usually, intentional movement of ...
Botox paralyzes facial muscles to prevent lines and wrinkles from forming, while Emface uses RF heat to smooth lines and forehead wrinkles. For what it's worth, I've tried all three: Botox, filler ...
A smaller temporalis muscle can actually indicate sarcopenia, which is the age-related loss of muscle mass and strength. “Systemic sarcopenia “is often linked to frailty, reduced mobility, and ...
In certain instances, excessive lower lid laxity creates the Fornix of Reiss – a pocket between the lower eyelid and globe – which is the ideal location to administer topical ophthalmic medications. Eyelid edema is a condition in which the eyelids are swollen and tissues contain excess fluid. It may affect eye function when it increases the ...
