Watch the full video lecture on YouTube: https://www.youtube.com/watch?v=JM0Azq72iz0 ## How to Draw and Label an Indirect Laryngoscopy Diagram In this post, you'll learn how to draw an **indirect laryngoscopy** diagram—step by step—and label all the structures that are visible through the mirror. This is a key practical skill for ENT students and residents. > 🎯 **Pro Tip:** The view you draw should reflect what is seen via the **laryngeal mirror**, which is **circular** and shows a **mirror image**—the **patient’s left** appears on your **right**. --- ### Step-by-Step Drawing Instructions ![Indirect Laryngoscopy Diagram](https://media.theentresident.com/post-images/indirect-laryngoscopy-diagram.png) 1. **Start with a Circle** - Since the laryngoscope view is seen via a round mirror, draw a **circular outline** to begin. 2. **Base of the Tongue** - The first structure you’ll see is the **base of the tongue**, located in the upper part of the mirror view. 3. Draw the **epiglottis** next - shape it like an **upper lip** structure. 4. **Glossoepiglottic Folds** - Draw the folds connecting the tongue to the epiglottis: - **Median glossoepiglottic fold** (in the center) - **Lateral glossoepiglottic folds** (on each side) 5. **Valleculae** - The **spaces between the median and lateral glossoepiglottic folds** are the **valleculae** (right and left). 6. Now, draw the **True vocal cords** in the lower central part of the diagram. - **Anterior commissure** is the point where the two cords meet in the front. 7. **Arytenoid Cartilages & Interarytenoid Area** - Posterior to the cords: - Draw two **arytenoid cartilages**. - The space between them is the **interarytenoid region**. 8. **Aryepiglottic Folds (AE Folds)** - Connect the arytenoids to the epiglottis with the **aryepiglottic folds**. 9. **Corniculate and Cuneiform Cartilages** - Located in the posterior part of the **AE folds**: - Draw small nodules for **corniculate** and **cuneiform cartilages**. 10. **Pyriform Fossae** - On each side of the AE folds, draw the **pyriform sinuses** or **pyriform fossae**. 11. **False Vocal Cords** - Just above the true cords, draw the **false vocal cords (vestibular folds)**. 12. **Tracheal Rings** - Below the cords, add the **tracheal rings** as semicircles. 13. **Postcricoid Area & Posterior Pharyngeal Wall** - Draw the **postcricoid region** just behind the trachea. - Behind that lies the **posterior pharyngeal wall**. --- ### Labeling the Diagram When labeling, always remember: > **The patient's left appears on your right side.** > Always draw accordingly. #### Structures to Label: - Base of the tongue - Epiglottis - Median glossoepiglottic fold - Lateral glossoepiglottic folds (right and left) - Valleculae (right and left) - True vocal cords - Anterior commissure - False vocal cords (vestibular folds) - Arytenoid cartilages - Interarytenoid area - Aryepiglottic folds - Corniculate and cuneiform cartilages - Pyriform fossae (right and left) - Tracheal rings - Postcricoid area - Posterior pharyngeal wall --- ### Clinical Tip: Vocal Cord Mobility - **To show normal mobility**, draw **bidirectional arrows** on both cords. - **In vocal cord palsy**, do **not draw arrows**. Instead, show a **cut mark** (slash) across the affected cord. --- ## About This Note This free ENT note on Indirect Laryngoscopy Diagram - How to Draw and Label was written by Dr. Mausumi Das and is paired with a corresponding video lecture.
