The procedure that involves making an incision into the trachea is known as a tracheostomy. This surgical intervention is performed to create an airway directly from the front of the neck into the trachea. It serves critical purposes, such as providing an alternative breathing pathway when the usual route is obstructed or compromised due to various medical conditions, such as severe asthma, trauma, or other respiratory issues.

In contrast, rhinoplasty is a surgical procedure focused on the nose, particularly for aesthetic or functional enhancements. Laryngoscopy, on the other hand, is a diagnostic procedure that involves examining the voice box (larynx) using a laryngoscope but does not require an incision in the trachea. Myringotomy is a surgical procedure involving the eardrum to facilitate drainage or insert tubes, distinctly unrelated to the trachea or respiratory pathways. Therefore, the only procedure among the options that directly entails an incision into the trachea is a tracheostomy.
