What is the diagnosis method for laryngeal cancer

Laryngeal cancer is a type of cancer, so it is inappropriate to conclude that it is laryngeal cancer based on symptoms alone. Therefore, it is very necessary to do some laryngeal cancer examinations. Understanding the examination of laryngeal cancer is very helpful for the patient's correct diagnosis. Let's learn about the diagnosis methods of laryngeal cancer.

Methods of diagnosing laryngeal cancer

1. Neck examination: This is one of the diagnostic methods for laryngeal cancer, including inspection and palpation of the external shape of the larynx and cervical lymph nodes. Palpation of cervical lymph nodes should be performed one by one from the submandibular, subhyoid, cricothyroid membrane, anterior trachea, suprasternal fossa, and the anterior and posterior edges of bilateral sternocleidomastoid muscles to find out the location and size of the enlarged lymph nodes, so as to determine whether there is laryngeal cancer.

2. Laryngoscopy: Indirect laryngoscopy is the most commonly used and simplest examination method. If you are not satisfied with the examination results or it is difficult to obtain pathology, you can use direct laryngoscope and fiber laryngoscope to further understand the invasion of laryngeal cancer tumors into the larynx, and take tissue from suspicious lesions for pathological examination in a timely manner.

3. Imaging examination: This is the most effective diagnostic standard for laryngeal cancer:

(1) X-ray examination: X-ray lateral laryngeal films and anteroposterior laryngeal tomographic films can clarify the general location, size and shape of laryngeal cancer lesions, as well as changes in the cartilaginous trachea or anterior cervical soft tissue. Laryngeal angiography can be performed if necessary.

(2) CT and MRI examinations: CT and MRI examinations can help determine the extent of laryngeal cancer tumor growth in the larynx, the extent of external invasion, and the status of cervical lymph node metastasis. They are especially helpful for patients with advanced laryngeal cancer.

(3) Ultrasonic tomography: A method used to detect enlarged lymph nodes in the neck, determine their location and relationship with surrounding tissues, and conduct follow-up examinations after postoperative radiotherapy. It has the advantages of being non-destructive, convenient, accurate, low-cost, and can be performed repeatedly.
