electrodesiccation

 [e-lek″tro-des″ĭ-ka´shun]
a type of electrosurgery that desiccates tissue by dehydration, which employs a spark gap type of generator to produce a highly or moderately damped alternating electrical current. It is usually used to remove small superficial growths on the skin.

e·lec·tro·des·ic·ca·tion

(ē-lek'trō-des'i-kā'shŭn),
Destruction of lesions or sealing off of blood vessels (usually of the skin, but also of available surfaces of mucous membrane) by monopolar high-frequency electric current.
[electro- + L. desicco, to dry up]

electrodesiccation

/elec·tro·des·ic·ca·tion/ (-des″ĭ-ka´shun) destruction of tissue by dehydration, done by means of a high-frequency electric current.

electrodesiccation

[-des′ikā′shən]
Etymology: Gk, elektron + desiccare, to dry up
a technique in electrosurgery in which tissue is destroyed by burning with an electric spark. It is used primarily for eliminating small superficial growths but may be used with curettage to eradicate abnormal tissue deeper in the skin or to stop bleeding. In the latter case, layers of skin may be burned, then successively scraped away. The procedure is performed under local anesthesia.

electrodesiccation

Surgery The drying of tissue by a high-frequency electric current applied with a needle-shaped electrode. See Dissection.

Electrodesiccation

To make dry, dull, or lifeless with the use of electrical current.

electrodesiccation

tissue destruction by controlled application of monopolar high-frequency electric current (Table 1)
Table 1: Forms of electrosurgery
Electrosurgery typeFeatures
ElectrofulgurationUses a high-voltage, dampened waveform to produce a spark that arcs from the probe tip to the skin lesion, causing superficial charring of the lesion surface
ElectrosectionUses an undampened or mildly damped current in conjunction with a very fine emitting electron to produce a cutting effect through soft tissue
ElectrocoagulationUses an intermittent damped current in conjunction with a larger emitting electrode to produce less intense heat over a larger area to induce coagulation and thereby haemostasis
ElectrodesiccationUses an intermittent damped waveform with high voltage and a lower current emitted from a ball electrode to induce cell dehydration and tissue shrinkage

electrodesiccation

a method of electrosurgery that desiccates tissue by dehydration. A highly or moderately damped alternating electrical current is radiated through a monoterminal active electrode that is applied directly to or inserted into the tissue being treated. See also electrosurgery.

8] Topical atropine or scopolamine electrodesiccation carbon dioxide laser and pulse dye laser have been used with good results.
The primary therapies for basal cell carcinoma are surgical excision (including Mohs surgery) and curettage, often combined with electrodesiccation.
8) Chemotherapy and electrodesiccation have been tried, but their role is limited.
The lesions were present against a background of multiple actinic keratoses, and were removed by electrodesiccation and curettage.
Other treatments--such as curettage (scraping away of diseased tissue), electrodesiccation (destroying diseased tissue by electric current), cryosurgery (freezing diseased tissue), radiation therapy, and standard surgical excision--are considered effective for some skin cancers.
Common AK treatments include cryotherapy (freezing), excisional surgery, electrodesiccation (burning) and curettage, lasers, topical chemotherapy and photodynamic therapy.
However, surgical excision or curettage and electrodesiccation may be performed for cosmetic reasons.
