When performing a direct laryngoscopy on a newborn, which additional procedure is commonly performed?

In the context of performing a direct laryngoscopy on a newborn, it is common to also perform a tracheoscopy. This procedure involves visualizing the trachea, allowing the physician to assess potential issues such as airway obstructions, abnormalities, or lesions that may also impact the larynx. The close anatomical relationship between the larynx and the trachea makes it practical and relevant to examine both areas in cases where airway intervention is necessary, especially in infants who may have congenital issues or other respiratory problems.

The other options—angioplasty, bursa drainage, and voiding pressure study—are not typically associated with direct laryngoscopy. Angioplasty is a vascular procedure, bursa drainage pertains to joint issues, and voiding pressure studies are related to urinary function, none of which are relevant to the upper airway examination performed during a laryngoscopy. Therefore, tracheoscopy is the logical complementary procedure that aligns with the goals of evaluating and addressing airway concerns in newborns during a direct laryngoscopy.
