This paper reviews the use of an intracavitary mold in the radiotherapeutic management of recurrent sub-orbital carcinoma of the maxillary sinus. An overview of the clinical features of antral carcinomas and the concept of brachytherapy in the management of these lesions is presented. Brachytherapy is usually reserved for relatively accessible lesions. Post-surgical and radiation-induced trismus can be a complicating factor, as in the case presented, where the inter-incisal distance was less than three millimeters. To circumvent the problem, a multi-layer antral plug was utilized as a carrier for the radioactive sources, and its construction is described.
本文回顾了腔内模具在上颌窦复发性眶下癌放射治疗管理中的应用。介绍了鼻窦癌的临床特征概述以及近距离放射治疗在这些病变管理中的概念。近距离放射治疗通常适用于相对易于接近的病变。手术和放疗引起的牙关紧闭可能是一个复杂因素，如本文所述病例，其切牙间距离小于3毫米。为解决该问题，采用了多层鼻窦塞作为放射源载体，并描述了其构造。
