Abstract
We report a retrospective study of 12 patients who underwent vertical partial laryngectomy for laryngeal carcinoma at Kyoundo Hospital, Sasaki Foundation from April 2007 to March 2012. All patients were male with the median age of 68 years (range 61-88). Six patients were treated as the first operation, 5 patients as salvage operation after radiation failure, and 1 patient was residual disease on TAR (RT = 34Gy). One patient had been treated by anterior frontal resection, 10 patients by fronto-lateral resection, and 1 patient by extended fronto-lateral resection. The complications were 2 cases with laryngeal necrosis, 2 cases with hematomas and 1 case with infection. All rT2 cases improved to pT3 because of paraglottic space invasion. One of three rT2 cases was local recurrence. One patient underwent total laryngectomy for aspiration pneumonia after local recurrence treatment. The laryngeal preservation rate was 91.7%. When operating on rT2 cases, it is important to consider the possibility of paraglottic space invasion.
