BACKGROUND: This study aimed to examine the plasticity of nerves indirectly by acoustic reflex after surgical repair of unilateral congenital aural atresia.
METHODS: This study is a retrospective study including 80 patients who had undergone surgical repairs of congenital aural atresia before 18 years old and for whom acoustic reflex testing was performed postoperatively. Several variables correlated with acoustic reflex were analyzed to find factors affecting the presence of acoustic reflex.
RESULTS: Among 80 patients, 44 were positive for acoustic reflex. As a result of multivariate analysis, good postoperative hearing (P = .017), younger age at surgery (P = .028), and the longer time interval between surgery and acoustic reflex test (P = .040) were revealed as factors affecting the acoustic reflex.
CONCLUSION: Acoustic reflex was present in 55% of surgically managed patients with congenital aural atresia. The results of this study imply that the reflex arc of acoustic reflex may be restored after proper surgical reconstruction and prolonged use of reconstructed ear in patients with unilateral congenital aural atresia.
