Prevalence of Plate Exposure After Mandibular Resection in Ameloblastoma Patients

Abstract Mandibular resection is a procedure to treat diseases or disorders of the mandible. Mandibulectomy is indicated for diseases involving the mandible. Plate exposure is a common postoperative complication of mandibular resection followed by reconstruction with plate fixation. Objective: This study was to obtain data regarding the number of plate exposed cases after madibular resection for indications of ameloblastoma at KSM Oral and Maxillofacial Surgery, RSUP Dr. Hasan Sadikin Bandung in the period January 2016 – December 2020. Methods: This study is a descriptive study using medical record data of patients diagnosed as ameloblastoma. The variables studied included age, gender, time of exposure, plate length, number of screws. Results: From the results of data collection for the last 3 years (2019-2021) at the Oral and Maxillofacial Surgery Section of Hasan Sadikin Hospital Bandung, it was found that the number of patients who underwent mandibular resection procedures in ameloblastoma cases was 25 patients. The patients consisted of 10 males and 15 females. AO plates were used as reconstruction material in 25 cases. Of the 25 cases, the exposure plate was found in 6 cases. Plate exposure occurs 4 years after resection in some cases. Of the 6 patients, 6 patients had plate removal. Conclusion: . Complications of plate exposure occur due to several factors such as age, plate length, and lack of adaptation of the plate. We must make a good plan of care during the preoperative period, by optimizing the condition of the patient before surgery to make a plan for proper plate placement, shaping and adjusting the shape of the plate, and estimating the need for graft placement.
