OBJECTIVE: To demonstrate the utility of Stens in patients with recurrent choanae atresia. CASE REPORT: Patient aged 13, male, with diagnosis of bilateral choanae atresia at birth, asked if emergency surgery via endoscopy to permeabilization of the choanae tissue extraction with posterior septum cartilage and bone portion thereof, from 4 years have bilateral nasal obstruction, rhinorrhea seromucous and mucopurulent where he received treatment with antibiotics with partial improvement of the framework, denies cyanosis. Nasal endoscopy is performed where it notes total obstruction of the choanae bilaterally. Computerized tomography where plaque notes that obliterates both choanae atresia. Takes place opening choanae atresia endoscopicaly and placing more STENS, at 15 days post - operative notes are output STENS accidentally arises again, intervened for the second time, it leaves the STENS for two months. Soon nine months after your surgery turns out hole permeable to level of choanae. CONCLUSION: the main problem they are in, all the techniques in chirurgery choanae atresia is a tendency to reestenosis, which requires performing many interventions in the patient.
