RadioSurgery In Colwall Stone

Moles, warts, skin tags and other so called ‘lumps and bumps’ can be both upsetting to look at and cause social and psychological unease for those whose face is blighted by such growths. With increases in the occurrence of skin cancers we are well advised to seek professional, medical advice about any growths which appear over night or change dramatically in appearance. Thankfully though, most growths are benign and harmless, and removal is often quick and simple with reassuring cosmetic results.
 
The term Radiosurgery is quite confusing in medicine as the term actually refers to two different surgical modalities. It is worth taking the time to look at the differences between the two to make sure there is no confusion.
 
The first radiosurgery (Stereotactic Radiotherapy) is a medical procedure which allows non-invasive treatment of benign and malignant conditions as well as vascular malformations by means of directed beams of ionizing radiation, such as gamma rays. This form of radiosurgery was first developed in Sweden in 1949 to irradiate brain tumour lesions.
 
The second type of radiosurgery (Radiofrequency or Radiowave surgery) is the cutting of tissues using a high frequency alternate current. This surgical modality is very different from traditional electrosurgery and other forms of electrocautery as it can simultaneously cut and coagulate tissues without applying any pressure.
 
Traditional electrosurgery devices cut skin tissue by passing an electric current through the patient and using the electrode tip (a platinum wire) to provide resistance, effectively causing high temperature heating of the electrode tip and excessive lateral (surrounding) tissue damage. There is also potential risk of shock and burn to the patient as well as post operative pain from unsealed nerve endings.
 
The principle of radiofrequency or radiowave surgery is that it uses high frequency radiowaves, at 4.0 MHz, to deliver low temperatures through radiofrequency (RF) micro-fibre electrodes. The waveband utilised is similar to the frequency of marine band radios.
 
The difference between this method and electrosurgery is that the tissue serves as the resistance instead of the electrode. This means there is no heating of the RF micro-fibre electrode by the use of low temperature RF radiowave energy. Instead, the intracellular tissue water provides the resistance and vaporises without the heat and damage seen in electrosurgery. This tissue vaporisation also results in significant haemostasis (stopping of the flow of blood) without actually burning the tissue. In addition, there is no danger of shocking or burning the patient.
 
Most important is the fact that there is controlled and minimal lateral tissue damage with 4.0 MHz high frequency, low temperature radiowave surgery. This effectively means less damage, less post operative pain, faster healing and less blood loss and better healing.

Careful discussions regarding your reasons for wanting treatment are very important before you begin the treatment. You must also make sure that this treatment can deliver what you want and how you would like to look afterwards. Your practitioner should be able to answer all these questions.

A medical history should also be taken to make sure that there are no reasons why you shouldn’t undertake treatment. You may be asked to read detailed information and sign a consent form which means that you have understood the potential benefits and risks associated with the procedure.

Photographs may also be taken by the practitioner for a "before and after" comparison at a later date.

Procedure

Radiofrequency surgery involves the passage of radio waves (frequency of 1.5 to 4.5 MHz) into the skin to perform removal or reshaping of a lesion. The commonest frequency used is 4 MHz.

The radio waves are generated by a radiosurgery unit, which creates a very high-frequency radio wave. The radio-surgical unit consists of an electrode, a ground plate and a transformer.

The ground plate or antenna is plastic coated and is usually placed under the patient. The “patient electrode” looks like a small loop and is held by the operating surgeon during the procedure. Different types of electrodes are used depending on the type of lesion e.g. fine needle electrode, wire loop electrode, scalpel blade electrode etc.

The lesion should be touched with the tip of the electrode. It generates very little heat as compared to conventional electro-cautery. This results in negligible collateral damage, resulting in faster healing and minimal scarring. The radiowaves travel from an electrode tip to the lesion and return to the unit through the ground plate. When radio energy passes between the ground plate and the patient electrode, it is concentrated at the electrode end, resulting in the release of energy, which produces steam within the cells, thus vapourising them and dividing the tissues. This occurs because of heat produced by the tissue resistance to the passage of a high-frequency wave. The heat makes the intracellular water boil and thereby increases the cell inner pressure to the point of breaking it from the inside to the outside. This phenomenon is called a cellular volatilisation.

Unlike with electrocautery, the electrode remains cold and no electrical contact needs to be made between the patient and the ground plate.

Many studies have demonstrated significant advantages to the use of electrosurgical incision, including shorter operating time, reduced postoperative pain, and sealing of lymphatics during excision of malignant tumours.

It is very important that you follow the advice of your practitioner carefully after any radiosurgery treatment to help to ensure the success of the procedure and reduce the risk of complications.
 
Post-treatment recommendations may include:

• keeping the area clean and dry for 2 – 3 days following treatment,
• contacting your practitioner immediately if you notice any signs of infection or if you experience heavy bleeding or a sudden increase in pain.

Generally a suitably trained and experienced doctor, dermatologist or cosmetic surgeon should perform all treatments that involve radiosurgery.

Please also note that all clinics offering minor surgical treatments should be registered with the Care Quality Commission. Clinics need to follow certain standards for the safe operation and maintenance of the machines that they use and the sterility of the environment in which they operate, and receive regular inspections to ensure that national minimum standards are followed.

For more information about practitioner training, qualifications and relevant medical organisations please view the information contained within the Legislation section of the Consulting Room.

Private prices for radiosurgery will depend upon the size and condition being treated, however prices for the removal of small moles, warts or skin tags start from approximately £100.

Results vary enormously depending upon both the patient and the skill of the individual surgeon, so outcomes for cosmetic surgery procedures will always be more variable than those for less invasive non-surgical treatments.

 Radiosurgery is commonly used to remove moles and skin growths.
