Not All Postoperative Stridor in Infants Is Due to Endotracheal Tube-Induced Subglottic Edema

Abstract

Abstract A 6-month-old infant presented with clinicoradiological features of a shunt dysfunction. Magnetic resonance imaging brain showed multiple leptomeningeal cysts in the posterior fossa, with the largest in the right cerebellopontine (CP) angle cistern causing compression on the brain stem and fourth ventricle. There was gross hydrocephalus with the malpositioned shunt tube. He underwent shunt revision followed by right retromastoid craniectomy and decompression of the right CP angle cyst. Following extubation, he developed stridor that was diagnosed initially as subglottic edema and treated with humidified oxygen, systemic corticosteroids, and nebulized adrenaline. Failure to resolve the symptoms warranted a video laryngoscopy that revealed right vocal cord palsy (VCP), and he was reintubated. He was started on steroids and got extubated on a nasal continuous positive airway pressure and was gradually weaned off. Intraoperative handling of the vagus nerve while decompressing the cyst led to a right VCP, which was communicated later to the anesthesiologist. Neurological cause and association need to be considered as one of the differentials while managing postoperative stridor after posterior fossa surgery in an infant. Timely communication between the surgeon and anesthesiologist is paramount for reducing morbidity.
