Depth dose in cryosurgery.
Depth dose can be estimated by instrumental or clinical methods. The physician learning to treat lesions is advised to use both methods together until confidence in techniques is gained. With experience clinical methods can be used confidently with benign lesions and basal-cell carcinomas in the upper 3 mm of skin. Instrumental supplemental monitoring should be used with malignant lesions capable of metastasis, basal-cell carcinomas deeper than 3 mm, and in treating any lesion in a location where extreme accuracy of depth dose evaluation is advantageous.
