Treatment Options
Sweat Glands
The human body has 2-5 million sweat
glands
Two main types:
ECCRINE
Click on the different sweat
gland types to learn more!

Click the “Home” button after viewing both types
APOCRINE
Eccrine Sweat Glands
Approximately 3 million
eccrine sweat glands
Secrete a clear, odorless
fluid
Aid in regulating body
temperature
Areas of concentration:
Facial, plantar, and axillae
Source: www.sweathelp.org
CLICK HERE
Apocrine Sweat Glands
Inactive until puberty
Produce thick fluid
Secretions come in
contact with bacteria on
the skin and produce
characteristic “body
odor”
Found in axillary and
genital areas

Sweating
The hypothalamus serves as the
thermoregulatory center
It controls both blood flow and sweat
output to the skin’s surface
Source: www.sweathelp.org
Sweating
The hypothalamus can be triggered by:
EXERCISE
STRESS
TEMPERATURE CHANGE
HORMONES
Source: www.sweathelp.org
Sweating
Once triggered,
the hypothalamus sends messages down the
spinal cord
via neurotransmitters.
Source: www.sweathelp.org
Sweating
The neurostransmitters travel down the
spine via ganglion or sympathetic nerves
These ganglion travel to nerves, which
reach the skin’s surface

Neurotransmitters
Neurotransmitters act as “vehicles,” transmitting
information from the hypothalamus to the skin’s surface.

The Whiteley Clinic, 2007
Neurotransmitters
The neurotransmitters can “exit” at various
places along the spinal cord.
The “exit” determines the location of skin
innervation.
Spinal Cord Innervations
T2-T4 innervate
the skin of the face
T4-T12 innervate the
skin of the trunk
Source: www.sweathelp.org
T2 – T8 innervate the
skin of the upper limbs
T10-T12 innervate the skin
of the lower limbs
Neurotransmitters
Acetylcholine

Hyperhidrosis
Hyperhidrosis is a state of
excessive sweating of the
axilla, palms, soles, or
face that interferes with
daily activities
Haider & Solish, 2004
Photo used with permission:
University of Miami Cosmetic Center, 2007
Two Types
 Primary
or idiopathic
 Secondary:
Resulting from respiratory/heart failure,
malignancy, drug/alcohol abuse,
hyperthyroidism, infection
Haider & Solish, 2004
Fun Facts
Diagnosed in 2.8% of the U.S. population
70% of those with symptoms do not
consult a physician
Peaks in early adulthood
Haider & Solish, 2004
Diagnostic Criteria:
Primary Hyperhidrosis
MUST HAVE
1. Focal, visible, excessive sweating
2. 6 months duration
3. No apparent cause
TWO
OR MORE:
1. Bilateral and symmetric sweating
2. Impairment of daily activities
3. At least one episode per week
4. Onset of less than 25 years
5. Positive family history
Hornberger, 2004
What is Hyperhidrosis?
Involves the eccrine sweat glands, however:
Sweat glands are NORMAL
No change in size
No change in shape
No change in number
Haider & Solish, 2004
Cause
Exact cause is unknown
Familial or genetic?
Excessive Sympathetic Activity?
Click on the raindrops to learn more about this theory!
Excessive Sympathetic Activity
The eccrine sweat glands
are excessively
stimulated by acetylcholine
Increased SWEAT production
Hornberger, 2004
Excessive Sympathetic Activity
Because the sweat glands are continuously
stimulated, they are stuck in the
position
Hornberger, 2004
QUIZ TIME!
Those diagnosed with hyperhidrosis have
abnormal eccrine sweat glands.
TRUE
FALSE
GOOD JOB!
The sweat glands are normal, with no
variance in size, shape, or number!
Take me to Question 2!
SORRY!
Try again….
Click on the sad face to try again!
Question 2
Hyperhidrosis involves which sweat gland
type?
Apocrine
Eccrine
Oops!
Take me back to the question!
YES!!
Hyperhidrosis involves the eccrine sweat
glands!

Treatment Options
Rules to Follow:
Different treatment for areas affected
Always start with least invasive treatment
option
Topical
Treatment Options
Click on the first treatment
option to begin!
Systemic
Iontophoresis
Botox
Local Excision
Thorascopic Sympathectomy
Topical Treatment
First line treatment
Aluminum Chloride Hexahydrate
antiperspirant of choice
Most beneficial for axillary
hyperhidrosis
Can be used for plantar and palmar
Hornberger, 2004
Photos used with permission:
www.feelbest.com
Topical Treatment:
How Does it Work?
The metal ions in the topical antiperspirant damage
the lining of the sweat gland.
As damage continues, a PLUG is formed over the
sweat gland.
www.sweathelp.org
Topical Treatment
Sweat production never
ceases, the gland is simply
plugged
Sweating will return as the
skin undergoes
regeneration or shedding

Neurosurgical Medical Clinic, Inc
Therefore…topical
treatment is NOT a cure!
Hornberger, 2004
Topical Treatment:
How to Use
Best to apply before bedtime
Allow to remain on skin for 6 – 8 hours
Apply every 24 – 48 hours until sweating
diminishes
Maintenance applications needed every 13 weeks
Hornberger, 2004
Topical Treatment:
Pros and Cons
Hornberger, 2004
Topical Treatment:

Thorascopic Sympathectomy
Endoscopic Thoracic
Sympathectomy (ETS)
Last treatment option
PERMANENT
Surgery performed under general
anesthesia
Haider & Solish, 2004
ETS
Goal of surgery is to excise or ablate the
ganglion that innervate the sweat glands
Performed most frequently for palmar
hyperhidrosis
Performed through
thorascope or video
Minimally invasive
Han, Oren, & Gottfried, 2002
Photo used with permission:
Neurosurgical Medical Clinic, Inc
ETS
Small incision made laterally under each
axilla
Incision made through intercostal space
Surgery can be performed on outpatient
basis
However, some patients remain in hospital
for one night
Han, Oren, & Gottfried, 2002
ETS
Ganglion located along
the sympathetic chain
Ganglion formed below
each rib
Ganglion can be divided
= sympathicotomy
Ganglion can be
removed =
sympathectomy
www.sweathelp.org
Photo used with permission:
Neurosurgical Medical Clinic, Inc
ETS
Ganglion at T2 and T3 = palmar
hyperhidrosis
Ganglion at T3 and T4 = axillary
hyperhidrosis
Ganglion at L2-L4 = plantar hyperhidrosis
www.sweathelp.org
Photos used with permission:
Neurosurgical Medical Clinic, Inc
ETS
Cannot surgically excise or ablate L2-L4
for plantar hyperhidrosis due to sexual
side effects
95% success rate in curing palmar
hyperhidrosis
Success rates slightly lower for axillary
hyperhidrosis
Eisenach, Atkinson, & Fealey, 2005
ETS
Plantar hyperhidrosis resolves in 50% 75% of cases when T2 and T3 are
excised, though L2-L4 ganglion are never
surgically treated
Mechanism is unknown!
Eisenach, Atkinson & Fealey, 2005
ETS: Side Effects
Surgical complications:
Hemo-pneumothorax requiring chest tube
placement – 1%
Atelectasis
Intercostal neuralgia – 1%
Horner’s Syndrome – 1%
Compensatory Sweating – 60%
Eisenach, Atkinson, & Fealey, 2005
Horner’s Syndrome
Stellate ganglion – fusion of C8 and T1
Innervates the face
If Stellate ganglion is damaged, Horner’s
Syndrome will occur
May be mistaken for T2 and T3
May receive electrical current from cautery of
T2 and T3
www.sweathelp.org
Horner’s Syndrome
Signs and Symptoms
Unilateral upper eyelid ptosis
Pupil constriction
Facial anhidrosis
www.sweathelp.org
Compensatory Sweating
Most frequent
complication – 60% of
post-op patients
Severe sweating noted to
abdomen, chest, back,
and thighs
More severe for those
who live in a hot climate
www.sweathelp.org

ETS Discussion Forum and Reversals, 2005
Compensatory Sweating
Mechanism poorly understood
Theory states:
Photo used with permission:
ETS Discussion Forum and Reversals, 200
After excision of T2 and T3, 40% of
body’s sweat function is lost
Body tries to compensate for this loss
Andrews & Rennie, 1997
Compensatory Sweating
Most patients feel compensatory
sweating is a minor draw-back to
surgery
Sweating to abdomen/trunk =
less interference with daily
activities
Able to write/handle objects
Gossot, Galetta, & Pascal, 2003

ETS Discussion Forum and Reversals, 2005
Let’s Review
ETS is performed most often for what type
of hyperhidrosis:
a.
b.

Axillary
Palmar
Plantar
CORRECT!
ETS is performed for palmar hyperhidrosis!
