Objectives
Determine the incidence of vocal cord paralysis and dysphagia after aortic arch reconstruction including Norwood procedure.
Setting
Tertiary Children’s Hospital
Study Design
Retrospective cohort.
Methods
Database/chart review of neonates requiring Norwood or arch surgery between January 2005 through December 2012. Demographics, postoperative vocal cord function, dysphagia, need for gastrostomy tube and/or tracheotomy, and long-term follow-up were reviewed.
Results
One hundred fifty-one consecutive subjects(96 Norwood, 55 aortic arch) were reviewed. Median age at repair was 9 days(IQR 7–13) for Norwood, 24 days(IQR 12–49) for arch reconstruction(p<0.001). Documentation of VC motion abnormality was found in 60/104(57.6%) subjects, and unavailable in 47:16 without documentation and 31 who expired prior to extubation. There were no significant differences in proportions of documented VC motion(p=0.337), dysphagia(p=0.987), and VC paralysis(p=0.706) between the arch and Norwood groups. Dysphagia was found in 73.5% of Norwood and 69.2% of arch subjects who had documented VC paralysis. Even without UVCP, dysphagia was present (56% Norwood,61% arch). Overall, 120/151(79.5%) required feeding evaluation and modified feeding regimen. Gastrostomy was required in 31% of Norwood and 23.6% of arch reconstruction overall. To date, mortality in this series is 55/151(36.4%) patients. Of those with VC paralysis, only 23(22%) had any otolaryngology follow-up after discharge from surgery. Over 75% with VC paralysis with follow-up after hospital discharge had persistent VC paralysis 11.5 months after diagnosis.
Conclusion
There is high incidence of UVCP and dysphagia after Norwood and arch reconstruction. Dysphagia was highly prevalent in both groups even without UVCP. Preoperative discussion on vocal cord function and dysphagia should be considered.
