What Are The Uses Of A Laryngoscopy

A laryngoscopy is used for the examination of laryngeal diseases and to assist in laryngeal treatment procedures. During examination, it allows observation of laryngeal structure and assessment of laryngeal function; during treatment, it can remove foreign objects from the laryngeal cavity and perform laryngeal surgery. Different precautions should be taken for different age groups and patients with different conditions during surgery.

 

Examination of laryngeal diseases:

Observation of laryngeal structure: Various parts of the larynx, such as the vocal cords, epiglottis, and pyriform fossa, can be clearly seen, including their shape, color, and movement. Through laryngoscopy, doctors can detect lesions such as congestion, edema, new growths (such as polyps, tumors), ulcers, and foreign bodies in the larynx. For example, in patients with hoarseness, laryngoscopy can help determine whether it is caused by vocal cord polyps, vocal cord nodules, etc., by observing the shape and movement of the vocal cords to clarify the cause. The manifestations of laryngeal diseases may vary in different age groups. Children's larynxes are more delicate, requiring more gentle and careful examination; the laryngeal tissues of the elderly may undergo degenerative changes, also requiring careful observation with a laryngoscopy to observe for any abnormal lesions.

Assessing Laryngeal Function: Laryngoscopy can assess the larynx's ventilation and vocal functions. For example, it can observe whether vocal cord vibration is normal and whether bilateral vocal cord movement is symmetrical, thus determining the functional status of the larynx. For patients with vocal difficulties due to laryngeal lesions, laryngoscopy can provide important information for developing appropriate treatment plans.

 

Assisting with Laryngeal Treatment Procedures:

Removing Foreign Bodies from the Laryngeus: When a patient has a foreign body in their larynx, the location of the foreign body can be directly observed through the laryngoscope. Then, using the operating channel of the laryngoscope, the foreign body can be removed using appropriate instruments. For example, children may sometimes inhale small objects into their larynx; the laryngoscope can accurately locate and remove the foreign body, ensuring the patient's respiratory safety. When removing foreign bodies from a child's larynx, special care must be taken to be taken to be gentle to avoid unnecessary damage to the child's larynx.

Performing Laryngeal Surgeries: In some laryngeal surgeries, the laryngoscope can serve as an important operating tool. For example, in procedures such as laryngeal tumor resection and vocal cord polyp removal under suspension laryngoscopy, the laryngoscope exposes the surgical site, providing a clear field of vision and operating channel for the surgical procedure, ensuring its smooth execution. When patients with different conditions undergo laryngeal surgery, the use of a laryngoscope should be adjusted according to the specific condition and the patient's physical condition to ensure the safety and effectiveness of the surgery.
