In the following image, identify the correct incision site of tracheostomy?
Appeared in: NORCET 8 Prelims-2025
Explanation
- The standard and safest site for a surgical tracheostomy is between the second and third tracheal rings.
- This location is chosen to avoid the cricoid cartilage superiorly, which prevents the complication of subglottic stenosis (narrowing of the airway).
- It also avoids the great vessels in the lower neck, such as the brachiocephalic artery, reducing the risk of major hemorrhage.
- The image correctly depicts a vertical incision made over this specific interspace, confirming the standard procedure.
- The isthmus of the thyroid gland, which typically overlies the 2nd to 4th rings, is surgically managed to expose this site (SRC_808).
Why Other Options Were Wrong
- Option B: While an incision between the third and fourth tracheal rings is a possible alternative, it is less common and considered a lower approach. This increases the risk of injuring the brachiocephalic artery or the pleura.
- Option C: Incisions are made in the membranous space between the cartilaginous rings, not directly on or through a single ring as the primary description of the site. This facilitates tube insertion and healing.
- Option D: Similar to the third ring, incisions are not described as being 'in' the fourth ring. This location is also considered too low and carries a significant risk of damaging major blood vessels and the lung apex.

Clinical Relevance
- Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Anatomical site for tracheostomy incision as background academic context rather than a clinical decision trigger.
- Nurses play a critical role in post-tracheostomy care, including stoma cleaning, suctioning, and monitoring for complications like bleeding, infection, or tube dislodgement.
- Immediate availability of emergency equipment at the bedside is a crucial patient safety measure. This includes a spare tracheostomy tube of the same size, one size smaller, and an obturator.
- Recognizing signs of respiratory distress in a patient with a tracheostomy (e.g., increased work of breathing, low oxygen saturation, audible secretions) requires prompt nursing assessment and intervention, often suctioning.
How to Approach the Question
- First, carefully examine the image and identify the labeled anatomical structures: Thyroid cartilage, Cricoid cartilage, and Tracheal rings.
- Locate the incision shown in the diagram relative to these landmarks. Note that the incision is below the cricoid cartilage.
- Count the tracheal rings starting from the one just below the cricoid cartilage (this is the first ring). The incision is shown spanning the next two rings (the second and third).
- Correlate this visual information with your knowledge of the standard surgical procedure for tracheostomy.
- Evaluate the given options. The option that describes the location as 'Between the second and third tracheal ring' accurately reflects the standard, safe surgical site shown in the image and described in textbooks.
- Eliminate options that describe incorrect locations (e.g., too high, risking stenosis) or are less precise (e.g., 'in' a ring rather than 'between' rings).
