Abstract:
Vocal cord paralysis （ VCP ） refers to the movement disorder of the vocal cord caused by the damage of the motor nerve conduction pathway that dominates the laryngeal muscles, which can be accompanied by sensory nerve disorder of the larynx. Symptoms of bilateral vocal cord paralysis include crying hoarseness, sucking cough, and laryngeal stridor, which can lead to asphyxia in severe cases. Our team recently used CO2 laser to treat such children, but the prognosis varies significantly. Case 1: A 2-year-old male, who had undergone tracheotomy 2 years prior, was diagnosed with "bilateral vocal cord paralysis with grade Ⅱ laryngeal obstruction" after birth. He maintained a tracheostomy until recently. Electronic laryngoscopy showed that the bilateral vocal cords were fixed in the midline, with a glottic fissure of about 1 mm. After surgical treatment, the outcome was good, and there was no recurrence during follow-up. A 1-year-old female, who had undergone tracheotomy over a year ago, was diagnosed with ' ①bilateral vocal cord paralysis; ②laryngomalacia; ③neonatal pneumonia.' She maintained a tracheostomy since then. Electronic laryngoscopy revealed that the bilateral vocal cords were retracted and fixed, with a glottic fissure of about 0.5 mm and limited vocal cord abduction. The postoperative outcome for this child was not good, and the tracheostomy tube was not removed.
