Unilateral choanal atresia: surgical technique and long-term results.

Abstract
Although transnasal techniques to treat choanal atresia have become the standard, risks remain of restenosis of the opened choana requiring dilatations. In addition, a new technique without stenting and requiring less invasive post-operative care would be an improvement. With this in mind, in a non-randomized trial, a modification of the transnasal surgical repair was used in eight patients with unilateral choanal atresia by which no stents were used. While the standard procedure consists of partial resection of the bony septum and the atretic plate, we additionally removed lower parts of the anterior wall and the floor of the sphenoid sinus, creating a new airway canal from the nasal cavity to the sphenoid into the epipharynx. Post-operative care by the patient and the surgeon was noted. The success of choanal patency was followed by nasal endoscopy and rhinomanometry with a mean post-operative follow-up time of 1.9 years. In all patients, both choanae remained patent confirmed by nasal endoscopy and rhinomanometry showing almost symmetric resistance. Post-operative care comprised antibiotic prophylaxis and nasal douching with saline solution by the patient; no further treatment by the surgeon was necessary. According to these long-term results we would recommend this type of surgery for two reasons: the use of stents no longer necessary and post-operative care by the surgeon can be minimized.
