End tracheostomy is performed in patients undergoing surgery for which of the following conditions?

Question

Accepted Answer

Laryngectomy. **Explanation:**

**1. Why Laryngectomy is Correct:**
An **End Tracheostomy** (also known as a permanent tracheostomy) is performed when the entire larynx is surgically removed (Total Laryngectomy). In this procedure, the distal tracheal stump is brought out to the skin of the neck and sutured to the margins of the skin incision. This creates a permanent stoma where the airway is completely separated from the pharynx and esophagus. Since the larynx (the connection between the upper and lower airway) is gone, the patient breathes exclusively through this stoma for the rest of their life.

**2. Why Other Options are Incorrect:**
*   **Laryngofissure surgery:** This is a thyrotomy where the larynx is opened to access the vocal cords. It usually requires a **temporary/prolonged tracheostomy** to maintain the airway during postoperative edema, but the larynx remains intact.
*   **Oropharyngeal growth:** These patients may require a **temporary tracheostomy** to bypass an upper airway obstruction or for anesthesia access, but the tracheal opening is not permanent.
*   **Obstructive Sleep Apnea (OSA) with stridor:** Tracheostomy is a treatment of last resort for OSA. It is a **temporary/permanent-in-situ** tracheostomy (the larynx is preserved), not an "End" tracheostomy.

**3. Clinical Pearls for NEET-PG:**
*   **End vs. Side Tracheostomy:** In an "End" tracheostomy, the trachea is severed and the end is brought to the skin. In a standard "Side" tracheostomy, an opening is made in the anterior wall of the trachea while the rest of the airway remains in continuity.
*   **Post-Laryngectomy:** Because the airway and food passage are separated, these patients **cannot aspirate** through the stoma, but they also cannot perform a Valsalva maneuver effectively.
*   **High-Yield Fact:** The most common indication for Total Laryngectomy (and thus End Tracheostomy) is advanced (T3/T4) Squamous Cell Carcinoma of the larynx. [Practice more ENT questions on OnCourse]
