{Abstract}: <B>OBJECTIVE: </B>To evaluate the outcome of a routine postoperative endoscopic micro-debridement of granulation tissue after stentless transnasal endoscopic repair of choanal atresia (CA).<BR><B>METHODS: </B>This prospective case series included congenital CA patients who underwent stentless transnasal endoscopic repair, followed by an endoscopic second look and micro-debridement of granulation tissue at 1-2 weeks post-repair. Patients were followed every three months for assessment of nasal airway symptoms and objective evaluation by flexible nasolaryngoscopy.<BR><B>RESULTS: </B>Sixteen CA patients (8 bilateral and 8 unilateral) underwent surgical repair (12 primary and 4 revisions). The median  age was 13 days (range 1 day-6 months) in bilateral and 3 years  (range 7 months-15 years) in unilateral atresia. The mean follow-up was 1.5 years (range 1 year-3 years). In primary procedures, the obstruction was bony-membranous in 7 cases and bony in 5 cases. The mean interval time between the CA repair and re-examination was 10.75 days (range 6-18 days). Clinically significant neochoanal restenosis was not encountered.<BR><B>CONCLUSIONS: </B>Re-examination under general anesthesia with endoscopic micro-debridement of granulation tissue is a safe, potentially effective adjunct when done during the proliferative phase of neochoanal wound healing. This procedure might help in maintaining neochoanal patency by remodeling tissue healing process. Large-scale, long-term cohort studies are imperative.
