Preoperative imaging and surgical margins in maxillectomy patients.

Background: High rates of positive surgical margins are reported after a maxillectomy. A large part of tumors that are preoperatively considered "operable" can thus not be resected with tumor-free margins.

Methods: This was a retrospective study on medical files of 69 patients that underwent maxillectomy as primary treatment for a squamous cell carcinoma.

Cine MRI of swallowing in patients with advanced oral or oropharyngeal carcinoma: a feasibility study.

Treatment of oral and oropharyngeal cancer may cause dysphagia. Purpose is to examine whether cine magnetic resonance imaging (MRI) yields additional information compared to standard examination in the evaluation of posttreatment dysphagia and mobility of oral and oropharyngeal structures. Thirty-four cine MRIs were made in 23 patients with advanced oral and oropharyngeal cancer, consisting of an MR image every 800 ms during swallowing which is compared to videofluoroscopy and quality of life questionnaires.
