Revised technique for intracavitary radiation of the nasopharynx

If intracavitary implantation is the most desirable treatment modality for nasopharyngeal carcinoma, then the use of the polysulfide rubber as a intracavitary implant is the preferred method. This technique is currently used at various patient treatment centers. Given sufficient time and significant patient numbers, this method of intracavitary implantation will prove to be the most convenient treatment modality.
