Predictive Factors for Success After Transnasal Endoscopic Treatment of Choanal Atresia

Abstract

Transnasal endoscopic repair of CA is a safe and successful technique. Predictive factors of restenosis are the presence of GERD, age younger than 10 days at the time of surgery, and insufficient postoperative endoscopic revision. However, previous surgery and associated malformations are not predictive of a poor surgical outcome.

Choanal atresia: A review of surgical outcomes in a tertiary medical center

“…In addition, restenosis in the bilateral CA group required more revision surgeries than in the unilateral group. This was in line with findings of other studies 6 , 12 and may be due mostly to the timing of the surgery. Bilateral CA required correction early in life (usually the first few days of life), and therefore associated with the challenge of the narrow nasal cavity of the newborn.…”

“… 16 Considering this in our material, 10 patients (33%) had bony atresia and 20 patients (66%) had mixed atresia. This was comparable with other studies (Gulşen et al: 30% bony and 71% mixed, 17 Brown et al: 29% bony and 71% mixed, 16 Wolf et al: 27% bony and 73% mixed, 18 Tessier et al: 34% bony, 66% mixed 6 ). The difference in the restenosis rate between these two types of atresia in our material was not significant.…”

Congenital Choanal Atresia Repair: An Analysis of Adverse Perioperative Events

“…In Teissier and colleagues’ series of 80 patients with CCA, infants <10 days of age had an increased risk of neochoanal restenosis. 21 This agrees with a related article by Friedman and colleagues where neonates who weighed ≤2.3 kg at the time of surgery had a less favorable outcome and an increased risk of neochoanal restenosis. 26…”

A 13-year experience and predictors for success in transnasal endoscopic repair of congenital choanal obliteration

“…The difference within each group was not statistically significant. In agreement with Friedman et al [34] and Teissier et al [13], it was noticed that older children had higher body weight, adequate blood count, and better general condition than younger patients.…”
