Abstract:
BACKGROUND AND OBJECTIVES: We evaluated the role of temporary injection laryngoplasty in patients with unilateral vocal fold paralysis (UVFP) after cardiothoracic surgeries. SUBJECTS AND METHOD: Taking the introduction of injection laryngoplasty as a milestone, we divided patients into those who underwent cardiothoracic surgery with UVFP during the years 2001-2004, before the introduction of injection laryngoplasty as pre-injection group (n=83) and those who underwent after the introduction during the years 2000-2007 as post-injection group (n=103). Of the post injection group, patients who received injection laryngoplasty postoperatively before being discharged were defined as injection group (n=37). Patients were also divided into non-esophageal surgery group and esophageal surgery group. Clinical outcomes including the length of hospital stay and oral feeding initiation time were compared between the pre-injection group and the injection group within the same operation group. The degrees of aspiration were classified into 4 grades. RESULTS: In the non-esophageal surgery group, the injection group with aspiration grade III had shorter hospital stay and oral feeding initiation time after extubation compared to the pre-injection group with grade III aspiration (p=0.042). However, in the esophageal surgery group, there was no statistical difference between the pre-injection and injection groups. CONCLUSION: Temporary injection laryngoplasty can reduce the hospital stay and enhance oral feeding initiation in patients with aspiration due to UVFP after non-esophageal cardiothoracic surgeries.
