Also known as Verrucas are growths on or within the skin due to Human Papillomavirus (HPV). The virus can be spread through scratching and touching other locations on the body. A wart will typically have a hard, surface with black spot/s through it due to blockages in vessels.
Diathermy utilizes an electrical current to cauterize the warts tissue resulting in their destruction subsequent removal. This method is favourable when compared to liquid nitrogen as it is specifically targeted with reduces the likelihood of scarring. 1 – 2 treatments generally suffice to eradicate the wart.
Non ablative lasers such as the Nd:YAG are becoming increasingly popular for treatment of warts due to their ability to specifically target the warts vascular supply and burn the affected tissue within the wart, whilst minimising trauma to surrounding tissue. Laser is often the treatment of choice for warts that have been unresponsive to other treatment options. Treatment number will vary depending on size and location of the wart generally between 2 – 3 treatments.
Either contact cooling, chilled air or topical anaesthetic is used to provide comfort during treatment.
Following diathermy the area is cauterised the area becomes inflamed which induces an immune response causing the wart to dry into a crust which generally falls off within 5 – 14 days after treatment. The area may require a second touch up treatment to remove all traces of the Wart, therefore preventing its reoccurrence. However, the immune reaction following treatment is usually efficient enough to remove the Wart.
The treatment of Warts with laser have a similar effect to diathermy treatment.
