1. Indications

The indications for performing contrast laryngography include the following:

• Evaluation of Laryngeal Lesions This procedure is indicated for assessing the presence of laryngeal tumors or benign lesions that may affect the function or appearance of the larynx.
• Investigation of Laryngeal Symptoms It is utilized in patients presenting with unexplained laryngeal symptoms such as hoarseness, difficulty swallowing, or persistent cough, to determine underlying causes.
• Assessment of Laryngeal Anatomy Contrast laryngography is performed to obtain detailed images of the laryngeal anatomy, which can assist in surgical planning or evaluation of structural abnormalities.

2. Procedure

The procedure for contrast laryngography involves several key steps that ensure accurate imaging of the larynx:

• Step 1: Anesthesia Administration The first step involves administering local anesthesia to the larynx to minimize discomfort during the procedure. This is crucial for patient comfort and cooperation.
• Step 2: Catheter Insertion Following anesthesia, a nasal catheter is carefully inserted above the epiglottis. This step is essential for delivering the contrast material directly to the laryngeal area.
• Step 3: Instillation of Contrast Material Once the catheter is in place, propyliodine, a radiopaque contrast agent, is instilled through the catheter. This contrast coats the mucosal surfaces of the larynx, enhancing visibility during imaging.
• Step 4: Radiographic Imaging After the contrast material has been applied, X-ray images are taken using indirect ionizing radiation. This imaging captures the laryngeal structures, allowing for detailed assessment.
• Step 5: Image Review The final step involves the physician reviewing the obtained images for any signs of disease, such as tumors or benign lesions, which may require further evaluation or intervention.

3. Post-Procedure

After the completion of contrast laryngography, patients may be monitored for any immediate adverse reactions to the contrast material or anesthesia. It is important to provide post-procedure care instructions, which may include recommendations for hydration and monitoring for any unusual symptoms. Patients should be informed about the potential for temporary hoarseness or throat discomfort following the procedure, which typically resolves on its own. Follow-up appointments may be scheduled to discuss the results of the imaging and any necessary further evaluations or treatments based on the findings.
