Brief Summary

The aim of this study is to evaluate the effectiveness of cryotherapy as a therapeutic option for oral lesions.

Detailed Description

Low-temperature applications were originally employed by the Egyptians to treat pain, and subsequently during the Franco-Prussian War for severed limbs. Hippocrates advocated the application of cold to lessen bruising, bleeding, and discomfort, while John Hunter wrote in 1777 that "the local tissue response to freezing includes local tissue necrosis, vascular stasis, and excellent healing." Using a solution of salt and ice, James Arnott (1851) was the first to describe and demonstrate this freezing technique for malignant breast tumors.

The term "cryotherapy" was used in 1908 to describe the use of extremely low temperatures to cure skin lesions. Currently, cryotherapy involves cooling the body's surface without destroying tissue, whereas in cryosurgery, sick tissues are frozen to death.

In the technique, several cryogens include: liquid nitroglycerine (-196 °C), Nitrous oxide (0°C), Solid CO2 (-78o C), Chlorodifluoromethane (-41°C), Dimethyl ether (-24 °C) and propane (-42 °C).

The intralesional technique, open method, or closed method can all be used to apply cryogens. The best application approach for big superficial cutaneous lesions is an open spray technique, in which the spray's nozzle is situated 1 cm away from the skin's surface, and the lesion is destroyed using either a paintbrush technique or a spiral technique.

Study Groups

Cryotherapy

Cryotherapy can be done in two ways:

1. Open technique: Using cotton swabs or a cryogun spray, the cryogen is delivered directly to the lesion in this technique.

2. Closed technique: Cryo-probes are used to apply the cryogen to the lesion in this procedure.

Group Type: EXPERIMENTAL

Cryotherapy

Intervention Type: OTHER

Cryotherapy can be done in two ways:

1. Open technique: Using cotton swabs or a cryogun spray, the cryogen is delivered directly to the lesion in this technique.

2. Closed technique: Cryo-probes are used to apply the cryogen to the lesion in this procedure.

The spray's nozzle of the Cryogun spray -50 ◦C was situated 1 cm away from the skin's surface and applied on the oral lesion for 30 seconds. Each freezing cycle lasted 10 to 30 seconds, with the subsequent 60-second thaw interval lasting twice as long as the freezing time. The ice ball that formed during freezing was totally melted before the subsequent freezing process could begin.

The application process should went from the core out to the edges. The management of lesions that are too big to be frozen by a single spray requires many overlapping treatments of liquid nitrogen. Mucoceles and erosive lichen planus took 30 to 50 seconds to freeze, whereas fibromas and leukoplakia took 60 to 70 seconds.
