[Role of cryotherapy in the treatment of small angiomas of the oral cavity].

Operative difficulties when attempting to treat oral cavity angiomas suggested the use, of cryotherapy for limited lesions. The technique is simple in use non-aggressive and has few after effects. The principle of cryotherapy has been known for a long time, but it was only in the 60's that it was applied in ophthalmology, neurology, dermatology, gynecology and the treatment of hemorrhoids, as a result of the availability of new products: Freon, liquid nitrogen. Conclusions as to the value of cryotherapy are drawn from results obtained in buccal mucosa affections treated by this method over the last four years.
