We report on a case of acquired choanal atresia which arose from palatal deformation caused by syphilis that the patient had had 40 years ago. The 64-year-old male patient had been complaining of a severe nasal obstruction that he had endured for a year. The uvula and bilateral palatine arches had adhered to the posterior pharyngeal wall, and the bilateral nasal choanae were found to be completely closed. The patient then underwent transnasal endoscopic surgery with a navigation system under general anesthesia. He was also treated with a mucosal flap and stented to prevent restenosis. A rolled silicone-plate was placed in the choanae for five days postoperatively. Sufficient patency of the choanae was been achieved and has been maintained. Restenosis has not been seen for 2 years postoperatively. Our findings suggest that the mucosal flap is effective in avoiding restenosis of the neochoanae.
