[Cause of failures in the cryodestruction of malignant tumors of the oral mucosa and tongue and the ways to increase the effectiveness of cryogenic action].
On the grounds of clinical observations over the use of cryodestruction on 109 patients with malignant neoplasms of maxillofacial localization it has been found that the recurrence took place mainly in cases when neoplasm was localized close to the large vessels (e.g. the lingual artery). The authors suggest to increase the cryoeffect through the artificial weakening of the speed of the blood flow in the vessels of the regions exposed to freezing. With this object in view, special experiments have been carried out and their results are described in the article.
