Abstract:
Neonates with laryngeal webs pose unique challenges to the anesthesiologist. We present a 2-day-old neonate with aphonia and stridor who underwent microdirect laryngoscopy. Intraoperatively, a Cohen type 4 laryngeal web was diagnosed not immediately amenable to resection. Therefore, the decision was made for endotracheal intubation and subsequent tracheostomy. After endotracheal intubation, there was acute respiratory compromise and oxygen desaturation that improved moderately after urgent tracheostomy. A chest radiograph revealed a large pneumothorax. Our experience suggests that in the presence of high-grade laryngeal webs, the possibility of intraoperative development of pneumothorax should be considered if respiratory difficulties are encountered.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...
