Keratocyst Odontogenic Tumor (KCOT): Treatment Methods at the Second Affiliated Hospital of Jiamusi University
Many studies have been done about the treatment of KCOT, but the recurrence rate still remains high despite the combination of surgical techniques used, associated with or without the use chemical solutions such as Carnoy’s solution or Cryosurgery. Currently, there is no consensus concerning the therapeutic choice for the KCOT. The purpose of this study was to evaluate the different treatment methods used for the management of KCOT in the Second Affiliated Hospital of Jiamusi University and the results obtained from those treatment methods. Settings and Design: Clinical study was done at the Second Affiliated Hospital of Jiamusi University. Materials and Methods: Analytical retrospective review of 63 cases treated surgically from 2009 to 2015 at the Maxillofacial and Oral Surgery Department of the Second Affiliated Hospital of Jiamusi University. All cases diagnosed as KCOT and registered in the archives were used. The level of statistical significance was set at P < 0.05. Results: Of the 63 cases, 55.56% were male and 44.44% female. The sex ratio was 1.25 in favor of male and the average age was 42 years. 81% of the lesions were located in the mandible. Of 40 cases treated by enucleation with peripheral ostectomy, curettage and electric cauterization with application of 2% iodine tincture, no recurrence was found. Of 20 cases treated by the same surgical method but without the application of 2% iodine tincture, recurrence was found in 3 cases (4.76%). 3 cases treated by resection had no recurrence. Significant relation between recurrence and type of treatment was found (P < 0.05). Conclusion: In our series, those cases that were treated by combination of surgical methods used with 2% iodine tincture showed an “improvement” in the reduction of recurrence, suggesting a future question to be examined in experimental study is to test the effectiveness of 2% iodine tincture.
