根据世界卫生组织的统计,印度次大陆的个体患口腔面部癌的患病率最高。手术,辐射,化疗,或组合疗法通常是用于治疗口腔癌的施用治疗方式。上颌骨区手术切除后的康复对于颌面修复医生来说通常是一项具有挑战性的任务。缺损的大小和位置通常会影响假肢康复的损伤量和难度。鼻腔和口腔之间的交流导致吞咽和言语困难,并产生不美观的外观。闭孔假体通常被用作修复半乳突切除术病例的有效手段。本文介绍了一例由于成釉细胞瘤而导致的获得性上颌骨缺损,手术切除后立即闭孔,然后是一件式封闭的空心球茎闭孔,通过利用剩余的腭和牙列来最大化支撑,稳定性,和保留,它是口腔和鼻腔之间交流的屏障。
According to WHO statistics, individuals of the Indian subcontinent have the highest prevalence of orofacial cancer. Surgery, radiation, chemotherapy, or combination therapies are commonly administered treatment modalities for the treatment of oral cancer. Rehabilitation after surgical resection of the maxillary area is often a challenging task for maxillofacial prosthodontists. The size and location of the defect usually influence the amount of impairment and difficulty in prosthetic rehabilitation. Communication between nasal and oral cavities causes difficulty in swallowing and speech and gives unesthetic appearance. Obturator prosthesis is commonly used as an effective means for rehabilitating hemimaxillectomy cases. This article presents a case of acquired maxillary defect due to ameloblastoma with unfavorable undercuts, which was successfully treated by an immediate obturator following surgical resection and followed by a one-piece closed hollow bulb obturator, by utilizing the remaining palate and dentition to maximize the support, stability, and retention, which acts as a barrier to the communication between the oral and nasal cavities.
