guidelines for Laryngeal Cancer-Laryngeal Cancer
Laryngeal cancer treatment compass to laryngeal cancer patients often appear to answer questions, such as: laryngeal cancer hanging what department number? Precautions before laryngeal cancer examination? What do doctors usually ask? What examination should laryngeal cancer do? What do you think of the laryngeal cancer examination results? Wait. The purpose of the laryngeal cancer treatment guide is to facilitate the patients with laryngeal cancer to seek medical treatment and solve the doubts of patients with laryngeal cancer.
Typical symptom
Pharyngeal foreign body sensation, throat blockage sensation, cough
Suggested visiting department
Oncology, Otolaryngology
Best visit time
No special, see a doctor as soon as possible
Duration of visit
Two days are reserved for the first visit and one day is reserved for the second visit
Frequency of follow-up visit/diagnosis and treatment cycle
Outpatient treatment: After the foreign body sensation in pharynx is relieved from weekly follow-up to gradually lengthened follow-up cycle, follow-up is uncomfortable. Severe cases need to be admitted to hospital for treatment, and then transferred to outpatient treatment after the laryngeal blockage is relieved.
Preparation before seeing a doctor
No special requirements, pay attention to rest.
Common consultation contents
1. Describe the reason for seeing a doctor (when did you start and what's wrong?)
2. Is the feeling of discomfort caused by obvious factors?
3. Have accompanying symptoms such as silent hoarseness, dyspnea and cough?
4. Have you been to the hospital, have you done those examinations, and what are the examination results?
5. How is the treatment?
6. Is there any history of drug allergy?
7. Are there laryngeal cancer patients at home?
Key inspection items
1. Neck check-up
Including observation and palpation of laryngeal shape and cervical lymph nodes. To observe whether the laryngeal body is enlarged, palpation of cervical lymph nodes should be carried out according to the distribution law of cervical lymph nodes, from top to bottom, from front to back, and gradually check to find out the location and size of enlarged lymph nodes.
2. Laryngoscopy
(1) Indirect laryngoscope examination is the simplest and easiest way, which can be completed in outpatient department. It is necessary to see all parts of the throat clearly during examination. Because of the patient's cooperation, it is sometimes impossible to check the laryngeal structures clearly, so it is necessary to choose other examinations such as fiberoptic laryngoscope. (2) Direct laryngoscope examination for those who have difficulty in taking biopsy under indirect laryngoscope, this examination method can be adopted, but the patient suffers greatly. (3) Fiberoptic laryngoscope examination Fiberoptic laryngoscope is slender, soft, flexible, bright, has certain magnification function, and has the function of taking biopsy, which is beneficial to see the whole picture of laryngeal cavity and adjacent structures, and to find tumors early and take biopsy. (4) Stroboscopic laryngoscopy can detect tumors early by dynamically observing vocal cord vibration.
3. Imaging examination
Through X-ray, CT and magnetic resonance examination, we can determine the invasion and metastasis of laryngeal carcinoma to surrounding tissues and tubes. Through superficial ultrasound imaging, metastatic lymph nodes and their relationship with surrounding tissues can be observed.
Step 4 Biopsy
Biopathological examination is the main basis for the diagnosis of laryngeal cancer. Sample collection can be done under laryngoscope. Pay attention to the central part of tumor, not on the ulcer surface, because there is necrotic tissue there. Some require repeated biopsies to confirm. Biopsy should not be too large or too deep to avoid bleeding.
Diagnostic criteria
Detailed medical history, physical examination of head and neck, indirect laryngoscope, laryngeal tomography, laryngeal CT and MRI examination can determine the location, size and scope of laryngeal cancer lesions. Pathological biopsy under indirect laryngoscope or fiberoptic laryngoscope is the most important method to determine laryngeal cancer. If necessary, biopsy can be taken under direct laryngoscope. The size and size of pathological specimens are different depending on the site. Laryngeal carcinoma in supraglottic area can be biopsied with larger specimens, while glottic type specimens should not be taken with too large specimens to avoid permanent vocal cord injury
