more complex autonomic dysfunction than generalised sympathetic overactivity

Cardiac autonomic function in patients (n = 63) with primary focal hyperhidrosis and healthy controls (n = 28) was investigated by short-term frequency domain power spectral analysis of heart rate variability. The power of the very-low-frequency band (0.01-0.05 Hz) was significantly lower in patients with axillary hyperhidrosis than in controls. No differences between groups could be observed at investigation of the low-frequency band (0.05-0.15 Hz), which was a surprising finding because this band represents also sympathetic cardiac innervation. At the high-frequency band (0.15-0.5 Hz), which represents parasympathetic cardiac innervation, an interaction of type and position influencing spectral power was detected. Our highly interesting findings indicate that primary focal hyperhidrosis is based on a much more complex autonomic dysfunction than generalised sympathetic overactivity and seems to involve the parasympathetic nervous system as well.

Side Effects

There is the possibility of increased sweating in other areas of the body for example the back of the legs.

Recovery Period

Patients will normally stay one day in hospital. Pain may be present for around a week, patients are normally given medication to control this. Most patients will be able to carry out their daily activities and return to work within a week.

Associated Risks

As with all types of surgery there are certain risks involved, these include infection, bleeding, reaction to anesthesia or nerve damage. The main risk of the surgery as stated before is increased sweating in other areas of the body.

dissociation between conductance and microvascular perfusion

Complete sympathectomy was accompanied by a persistent increase in ear temperature and a dissociation between conductance and microvascular perfusion. Auricular conductance was transiently increased and then decreased to levels below preoperative control values. Microvascular perfusion is decreased immediately following amputation/replantation and thereafter increases.

'Emotional' sweating regulated by neocortex and limbic cortex

Careful observations showed that the forearm sweating responded diversely to various mental stimuli, unlike the palmar sweating whose response was always an increase. Mental arithmetic, mental testing and physical exercise caused an immediate increase in the palmar sweating but often elicited a transient decrease in the forearm sweating, whereas pain, noise, and emotional stimuli consistently provoked an increase of sweating on the forearm as well as on the palm. These observations suggest that the activities of higher centers, presumably involving neocortex and limbic cortex, exert various influences on the central mechanisms of palmar and generalized sweating.

90% may experience Gustatory sweating after surgery for Hyperhidrosis

Some individuals (up to 90%) may experience another type of sweating that is increased while eating or smelling certain foods (gustatory sweating) (Hornberger).
