What are the methods for laryngeal cancer examination?

Laryngeal cancer is not common among all tumors in the body, accounting for about 1%-5% of all tumors in the body, and the incidence rate in women is higher than that in men. Laryngeal cancer is most common in squamous cell carcinoma, with glottic cancer being the most common, followed by supraglottic cancer, and subglottic cancer being rare. The examination method for laryngeal cancer is very important, which helps in the early detection and diagnosis of laryngeal cancer, so that patients with laryngeal cancer can receive timely treatment. The following experts will introduce to you the examination methods for laryngeal cancer.

1. Neck examination:

The main focus is on inspection and palpation of the laryngeal shape and cervical lymph nodes. The cervical lymph nodes should be palpated from top to bottom and from front to back according to the distribution pattern of cervical lymph nodes to gradually check and clarify the location and size of the swollen lymph nodes.

Second, laryngoscopy:

The commonly used method in clinical practice is indirect laryngoscopy. Only when the indirect laryngoscopy examination is unsatisfactory or it is difficult to obtain pathology, direct laryngoscope and fiberoptic light guide can be used to further understand the tumor invasion of the larynx and to take tissue for pathological examination in a timely manner for suspected diseases. In the late stage of laryngeal cancer, the vocal cords are thickened in the early stage, the vocal cords are congested on one side, the surface is rough and uneven, and granular protrusions gradually appear on the surface of the vocal cords, and then become papillary or cauliflower-like tumors. After a while, the movement of the vocal cords is restricted or fixed. In the late stage, it often becomes ulcers and develops to the upper and lower parts of the larynx to invade the adjacent tissues of the larynx, and there is cervical lymph node metastasis.

3. Imaging examination:

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

(2) CTMR examination: It helps to determine the extent of tumor growth in the larynx, the extent of external invasion, and the status of cervical lymph node metastasis, which is especially helpful for patients in the advanced stage.

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

Laryngeal cancer patients need to have a correct examination method, timely and correct understanding of the condition, and active symptomatic treatment to better control the development of the disease.
