Functional resection of the oropharyngeal cancer of lateral wall type

Abstract

The author conducted a review of 19 patients who had undergone resection of lateral wall type oropharyngeal cancer at Okayama University Hospital for between September, 2006 and August, 2014. General diet was eaten in 11 of 12 patients in the T2 cases, but six of seven patients were able to eat only mixer food in the T4a cases. Posterolateral resection was performed in the layer of the internal carotid, all seven cases for eight of 12 T2 cases and all T4 cases. Six of seven T4a cases were able to eat only mixer food, but, as for seven of eight T2 cases, intake of the general diet was possible, and the posterolateral resection along the internal carotid was not a factor for swallowing dysfunction. The resection of the base of tongue was performed in seven T4a all cases. Seven of 11 patients who underwent base of tongue resection were able to eat only mixer food. Resection of the base of tongue seemed to be the factor in for postoperative swallowing dysfunction T4a cases.
