Comparison of Mastication Status in Ameloblastoma Patients Post-Mandibular Segmental Resection Operation with LC Type with Mandibular Reconstruction using Plate And Plate Bone Graft in RSUD Dr. Soetomo

Abstract

Background: Mandibular resection is part of the surgical operation for ameloblastoma cases, followed by mandibular reconstruction. Good masticatory status should be taken into account in determining the success of mandibular reconstruction. To assess mastication, some measuring instruments in the form of a questionnaire were created, one of which is the Tsuga questionnaire. At RSUD Dr. Soetomo Surabaya, the most common resection performed is mandibular segmental resection with an LC type defect, where an assessment of mastication status had not been carried out in this case. Methods: This study is an analytic study to see the mastication status of patients after mandibular resection and reconstruction with a case-control study design. This study used primary data in the form of interviews and secondary data in the form of medical records of ameloblastoma patients who had undergone mandibular resection surgery with an LC type defect and underwent mandibular reconstruction at RSUD Dr. Soetomo Surabaya. Results: The total research subjects were 50 people, consisting of 26 men (52%) and 24 women (48%). From the results of the study, there was no statistically significant relationship between the age group and mastication status after mandibular reconstruction (p-value = 0.765) and also between gender and mastication status after mandibular reconstruction (p-value = 0.725). Meanwhile, between the type of reconstruction and mastication status, there was a statistically significant relationship (p-value = 0.011). It was also found that patients with the type of reconstruction using a plate bone graft had five times better mastication status than those who used the type of reconstruction using a plate. Conclusion: There is a statistically significant relationship between the type of reconstruction and mastication status. Mandibular reconstruction in postoperative ameloblastoma patients with mandibular segmental resection with LC type defects using plate bone graft has a better mastication status than those using plates without bone graft.
