Endoscopic percutaneous suture lateralization with syringe needles for neonatal bilateral vocal cord paralysis

ObjectiveTo explore the novel technique of percutaneous endoscopic suture lateralization for bilateral vocal cord paralysis (BVCP) in neonates from Shenzhen, China, and to evaluate the safety and efficacy of the operation.MethodsIn this retrospective case series, we present four neonates with BVCP diagnosed within 3 days after birth from Shenzhen Children's Hospital. All had stridor, respiratory distress and hypoxemia requiring respiratory support at diagnosis. Endoscopic vocal fold lateralization was performed under general anesthesia using 3.0 mm endotracheal intubation through the improved technique of percutaneous needle-directed placement of a 4–0 Prolene suture, without the use of specialized equipment. A 4–0 Prolene wire was led out through two 10 ml syringe needles, the left vocal cord was fully moved and fixed under the skin with endoscopy monitoring.ResultsOverall, 3/4 of the patients showed clinical improvement in stridor and dyspnea 2–3 weeks after the operation and avoided a tracheostomy, two of them could breathe and feed normally when they were discharged from hospital, and one patient had a weak ability to suck but could breathe normally. The last patient had to undergo a tracheotomy due to the poor improvement in respiratory distress. None of the babies experienced any complications from this surgery, but case four presented with a series of complications and other problems in postoperative care related to the tracheostomy. At the last follow-up (mean 8 months), complete function of the bilateral vocal cords was acquired in case two (6 months) and partial function of the vocal cords was acquired in case one (13 months), with the other cases still experiencing paralysis.ConclusionEndoscopic percutaneous suture lateralization may be a reversible, effective and minimally invasive primary treatment for neonatal BVCP. Most of neonates with BVCP undergoing this procedure avoided a tracheotomy.
