The mechanism of cryosurgery

Cryosurgery is a method of destroying pathologically changed tissues, which is known for a long time. During the procedure, very low temperature is generated which leads to freezing of water within tissues resulting in their death. In the next stage the treated tissues undergo dissociating and new epidermis appears in their place.

Indications:

Viral infections:

  • viral warts
  • flat warts
  • fig warts
  • epithelial molluscum

Cancers and precancerous skin conditions:

  • senile seborrhoea
  • leucoplakia
  • warty horn
  • keratoacanthoma
  • basal cell carcinoma
  • Bowen’s disease
  • erythroplasia of Queyrat

Skin changes:

  • seborrheic keratosis
  • fibroma
  • granuloma faciale
  • angiogranuloma
  • granuloma annulare
  • sebaceous hyperplasia
  • musoust cysts
  • prurigo nodularis
  • corns, tyloma
  • angioma
  • keloids
  • alopecia areata (cryostimulation)

Contraindications:

Depending on indications for undergoing the treatment: a tendency for appearance of keloids.

The process of treatment:

The best result is achieved by using the method of binal cryonics of a change (cryonics, thawing and another cryonics). Thanks to a wide choice of probe’s ends it is possible to perform precise treatment regardless of its size and location. It shall be remembered, though, that a choice of a proper end as well as the time of cryonics depends on a type of a change, its location and the condition of patient’s skin.

Post treatment indications:

  • avoid sun exposure for 4 weeks
  • use sun protection – a cream with +50 sunscreen

 

The frequency of treatments:

Viral wards, seborrheic wards, venereal warts, solar keratosis, surface skin cancers – changes can disappear even after one treatment, though usually there is a need to repeat the treatment after a fortnight.
Keloids, nodular prurigo – usually a few treatments are needed with the breaks of 14-30 days
Alopecia areata – a series of minimum 5-10 treatments is needed

Convalescence time:

  • pain discomforts connected to the treatment usually disappear within a few hours. In case of changes located on feet in sporadic cases the pain may hinder moving
  • skin reddening appears after the treatment and usually disappears within a few days
  • skin swelling appears usually immediately or a few hours following the treatment and remains 1-2 days
  • blisters can appear after cryotherapy treatment of changes located on a scalp and feet. After their appearance, you should pierce them with a sterile needle and cleanse with some antiseptic. They usually heal within 7 days.
  • desquamation is converging inflammatory process resulting from cryotherapy and usually appears 3-6 days following the treatment and lasts for 7-9 days
  • post inflammatory hyperpigmentation appears as a result of converging inflammatory process connected to damage of tissues. They can be visible up to a few months following the treatment
  • scars appear most often in case of cryotherapy of cancerous type changes

The effect of the treatment:

  • removing or flattening skin changes
  • stimulation of hair growth

Time: depending on the amount of changes 10-30 minutes
Anaesthesia: no
Complementary treatments: curettage, fractional laser CO2, pharmacological treatment
