Hyperhidrosis

Hyperhidrosis or excessive sweating is believed to be secondary to over activity of the sympathetic nerves located in the chest cavity. Surgical treatment of hyperhidrosis involves interrupting the sympathetic nerves.
These nerves have 12 segments in the thoracic cavity from T1 to T12. This procedure is called endoscopic thoracic sympathectomy. In its different variations it is referred to as ETS, ETS-C, or ESB.
Sympathectomy is performed through small keyhole incisions in the underarm area under general anesthesia. The sympathetic nerves are then found in the thoracic cavity and are either cut, clamped or resected.
Sympathectomy can be achieved by various methods:
Sympathectomy by clamping or clipping (ETS-C / ESB)
In this method the sympathetic nerves are interrupted but not physically cut. This is accomplished by applying a titanium clip/clamp to the nerve. The pressure from the clamp interrupts the nerve signals through the sympathetic nerves. The sympathetic ganglia are not destroyed. The advantage of the method is the theoretical possibility of reconstructing the nerves in the future by removing the clamps.
Sympathectomy by cutting
In this method the sympathetic nerves are physically cut with scissors or electrocautery. The disadvantage of this method is that it is extremely difficult to reconstruct the sympathetic nerves in the future.
Sympathectomy by resecting the sympathetic nerves
Some surgeons prefer the removal of a segment of the sympathetic nerves. This method is effective in treating various forms of hyperhidrosis. However again it is extremely to reconstruct the sympathetic chain after this procedure.
The extent of sympathectomy
The extent or level of the endoscopic sympathetic blockade, ESB, varies according to the type of hyperhidrosis or facial blushing:
            Condition                         Level of ESB
            Facial Blushing                      T2
            Facial Sweating                T2 or T3
            Hand Sweating                 T3 or T4
            Underarm Sweating           T4 or T5
       
It is believed that by limiting the level of ESB to a specific segment of the sympathetic chain, compensatory sweating, the most common side effects of surgery, can be reduced.

Cystic Hygroma

A cystic hygroma is a growth that often occurs in the head and neck area. It is a birth defect.
Causes, incidence, and risk factors

A cystic hygroma occurs as the baby grows in the womb. It forms from pieces of material that carry fluid and white blood cells. This material is called embryonic lymphatic tissue.

After birth, a cystic hygroma usually looks like a soft bulge under the skin. The cyst may not be found at birth. It typically grows as the child grows. Sometimes it is not noticed until the child is older.
Symptoms

A common symptom is a neck growth. It may be found at birth, or discovered later in an infant after an upper respiratory tract infection.
Signs and tests

Sometimes, a cystic hygroma is seen when the baby is still in the womb using a pregnancy ultrasound. This can mean that the baby has a chromosomal problem or other birth defects.

The following tests may be done:

Chest x-ray

Ultrasound

CT scan

If the cystic hygroma is detected during a pregnancy ultrasound, other ultrasound tests or amniocentesis may be recommended.
Treatment

Treatment involves removing all of the abnormal tissue. However, cystic hygromas can often spread to other parts of the neck, making it impossible to remove all of the tissue.

Other treatments have been tried with only limited success. These include:

Chemotherapy medications

Injection of sclerosing medications

Radiation therapy

Steroids

Expectations (prognosis)

The outlook is good if surgery can totally remove the abnormal tissue. In cases where complete removal is not possible, the cystic hygroma commonly returns.

The outcome may also depend on what other chromosomal abnormalities or birth defects, if any, are present.
Complications

Complications may include:

Bleeding

Damage to structures in the neck caused by surgery

Infection

Return of the cystic hygroma
