CRYOTHERAPY IN MANAGEMENT OF ORAL LESIONS USING LIQUID NITROGEN –A CASE STUDY

Abstract

Aim of the study to Evaluation of the efcacy of cryotherapy as a treatment modality for Oral lesions Objectives: to evaluate the post- operative clinical outcome of oral lesions after treatment with cryotherapy, with respect to Ÿ Post- operative wound healing. Ÿ Recurrence of the lesion Results: There was no slough formation in 46. 7 %( 7) of the patients on 1 stweek post treatment and 53. 3%(8) of the patients had slough formation. After 2 weeks post treatment 46. 7% ( 7)of the patients had fair amount of granulation tissue formation and 53. 3%(8)of the patients had a good amount of granulation One month after treatment there was fair epithelization in 53.3% (8)of patients and 46 .7%(7) of patients had good epithelization. There was recurrence of the lesion in 13.3%( 2) after 2months and 86.7 %(13 ) of them had no recurrence. , Low complication rate, minimal volume of tissue destruction, Particularly suited to extensive supercial lesions. Conclusion: Cryosurgery is the use liquid nitrogen were extreme cold is produced to destroy abnormal tissue. Cryosurgery is very safe, easy to perform and relatively inexpensive technique for treating various oral lesions in out-patient clinic it is very useful for oral lesion as the oral mucosa. . In this study the open method used to treat lesion with cryogen spray using liquid nitrogen has shown signicantly good results in achieving complete regression of the benign and premalignant lesion of oral cavity .
