Abstract:
Objective: To describe and evaluate the surgical effect and prognosis of nasal endoscopic modified mucosal flap technique for repair of congenital choanal atresia in newborns and infants. Methods: The clinical data of 38 newborns and infants with congenital choanal atresia who underwent nasal endoscopic surgery in Beijing Children's Hospital between January 2016 and May 2018 were retrospectively analysed, including 13 males and 25 females. The age ranged from 5 days to 3 years old at the time of operation (15 cases were newborns). The clinical data, imaging data, treatment effect and prognosis were collected. According to the different surgical methods, the patients were divided into the conventional operation group and the modified mucosal flap technique group. The designs of the modified mucosal flap technique were designed according to the type of congenital choanal atresia. The cross-over L-shaped flaps were performed in patients with unilateral atresia, and the mirrored L-shaped flaps were performed in patients with bilateral atresia. All the patients were followed up for 2-3 years, and the follow-up parameters included the times of operations, length of hospital stay, restenosis rate and incidence of complications. Study data was analyzed using SAS version 9.4 statistical software. Results: Sixteen cases underwent conventional operation while 22 patients underwent modified mucosal flap technique under nasal endoscope. The lightest weight (2 200 g) and the youngest age (5 days) of the patients came from the modified mucosal flap technique group. Compared with the conventional operation group under nasal endoscope, the modified mucosal flap technique group had fewer times of operations (1.14±0.47 vs 2.69±1.20, t=5.552, P<0.001), shorter hospital stay ((7.70±3.22) d vs (14.37±19.16) d, t=2.960, P=0.005), lower rate of postoperative restenosis (9.1% vs 43.8%, χ²=6.156, P=0.013), and lower rate of the incidence of complications (13.6% vs 43.8%, χ²=5.955, P=0.015), the differences were statistically significant. Conclusion: The nasal endoscopic modified mucosal flap technique is feasible for repairing congenital choanal atresia in newborns and infants, which can significantly reduce the incidence of postoperative restenosis and complications.
