Cryotherapy for oral potentially malignant disorders.

Four surgical treatment modalities namely cryosurgery, scalpel and blade surgery, diode LASER surgery and CO2 LASER surgery in the management of oral potentially malignant disorders (OPMDs) in terms of healing outcomes post operatively and recurrence is evaluated. The study included sixty outpatients whose biopsies revealed OPMDs (oral lichen planus, homogeneous leukoplakia, non-homogenous leukoplakia and erythroplakia). There is decrease in post-operative pain and oedema in all four treatment categories at one week follow up and two week follow up. It was observed that pain was low in cryosurgery treatment category at day of surgery as well as at one week of follow up as compared to diode LASER and CO2 LASER. Observations from the study highlights that all four surgical modalities used in this study were effective for treatment of OPMDs, and the overall summation of the results of the study showed that cryotherapy seems to offer better clinically significant results than laser therapy.
