Large defects of the hard palate can result from a congenital abnormality, trauma, or surgical treatment of oral masses. Closure of these defects can be challenging as dehiscence is common. Large, inoperable hard palate defects may be managed with prosthetic obturators, which recreate the separation between the oral and nasal cavities. This report describes the use of a palatal obturator to manage a large palatal defect that persisted after resection of a palatal fibrosarcoma. Three prior attempts at surgical closure of the defect had failed.
硬腭的大缺损可能由先天性异常、创伤或口腔肿物的外科治疗引起。由于裂开很常见，闭合这些缺损可能具有挑战性。大型、无法手术的硬腭缺损可用修复性阻塞器进行处理，该阻塞器可重建口腔和鼻腔之间的分隔。本报告描述了使用腭部阻塞器处理腭部纤维肉瘤切除术后持续存在的大型腭部缺损的情况。此前曾三次尝试手术闭合该缺损，但均失败。
