Useful combination of Gehanno method, polyglycolic acid sheet and fibrin glue for prevention of postoperative dysfunction after soft palate resection with TORS.

Oropharyngeal cancer requiring combined resection of the soft palate is relatively out of indication for transoral robotic surgery (TORS) due to postoperative functional problems. We report the case of a patient with oropharyngeal cancer in which half of the soft palate was resected, and good function was maintained using the Gehanno method, polyglycolic acid (PGA) sheet and fibrin glue. The patient was a woman in her 50 s with oropharyngeal squamous cell carcinoma (p16-positive, T2N1M0 stage I). TORS and right neck dissection were performed the same day. About half of the soft palate was resected cranially. After closing the right nasopharynx with the Gehanno method, the sutured part was reinforced by covering with a PGA sheet of about 10 mm on a side and fibrin glue. Oral feeding was started on postoperative day 4, but no nasal reflux was observed. Three weeks postoperatively, no nasal reflux was evident, normal food intake was possible, and nasal breathing was maintained. This technique may be effective after TORS surgery that requires soft palate resection.
