The height of the breasts is affected by the position of the shoulders.  The muscles of the chest known as pectoralis minor and pectoralis major tend to rotate the shoulder inward and downward.  The opposing muscles of the back such as the rhomboids tend to pull the shoulder backward.  The theory is that if the muscles such as the pectoralis minor were weakened, this would result in unopposed movement of the shoulder upward and backward, thus lifting the breasts to a more prominent and esthetically pleasant position. This is the basis for the botax breast uplift procedure.

The fact that this works is proven in tests where the pectoralis minor on each side is given a botox injection dose of about 30units of botax (more commonly known as botox).  Botax weakens the pectoralis minor muscles and the breast uplift occurs as a result.  A somewhat pleasant side effect as yet unexplained is the stimulation of the nipples which remain erect for a month.

Breast Uplift With Botax - Before

Breast Uplift With Botax - After

The botax effect lasts about 3 – 4 months.  It is noted that the breast up lift effect is more obvious in people with slightly smaller breasts, about cup size A or B.  Upon wearing out of the effect in about 4 months, the breasts start to descend, and it is time for a repeat dose of botax. 

These are:

cervical dystonia (spasmodic torticollis) (a neuromuscular disorder involving the head and neck causing painful spasms of muscles of the neck with abnormal positioning of the head).  Botox injections will reduce the spasms of these muscles.
blepharospasm – a situation where there is involuntary spasm of the eyelids or muscles around the eyes. Mild degrees of this affect almost everybody, causing tics or twitching of the muscles near the lower eyelids.  Botox treatments will do pretty well.

hyperhidrosis  An excessive sweating of palms, armpits, and soles of feet. A very embarrassing situation which results in cold wet palms and armpit sweat stains, especially obvious on white shirts.
achalasia of the cardia – a situation where there is failure of the sphincter of the lower esophagus to relax to allow food to pass through to the stomach, causing food to overflow potentially causing flooding of the lungs.
migraine and other headaches, which are thought to be aggravated my spasms or contractions of muscles in the scalp.
 
Other uses of botox commonly seen in other countries but which have not yet been FDA approved are:

pediatric and adult incontinence (possibly due to overactive bladder)
incontinence due to neurogenic bladder (related to spontaneous bladder muscle contractions when the bladder is full)
anal fissure (relaxation of the anal sphincter from the botox injection allows the fissure to heal)
spasms of muscles due to brain problems such as stroke, parkinson’s disease, cerebral palsy and also localised muscle spasms affecting the face, jaw or vocal cords and limbs
Pain of the Temporomandibular joints due to spasm of related muscles
wound healing
excessive production of saliva
diabetic neuropathy.
treatment of chronic headaches and muscle pains
weight loss and recently,

depression  (indirectly, by eliminating frown lines causing the patient to look more cheerful, and thus feel more cheerful)
