Three types of causes can cause sonar
"The causes of hoarseness are more complex and can be roughly divided into three categories." Wang Chenghua introduced that the first category is the hoarseness caused by mild inflammation or edema, such as acute, chronic laryngitis and laryngeal edema caused by colds. . "Such sonars can usually be recovered after a period of symptomatic treatment and rest." Such "silence" is often related to occupations, such as teachers, actors, presenters, telephone service personnel, etc. Due to excessive fatigue caused by vocal cords, hoarseness can be effectively restored as long as it is properly rested.
The second type of hoarseness is caused by laryngeal organic diseases, including benign lesions such as vocal cord nodules and vocal cord polyps, precancerous lesions such as laryngeal leukoplakia and laryngeal papilloma, and even malignant tumors of the larynx. "What needs to be emphasized is that the incidence of laryngeal cancer has been younger in recent years. For Cantonese, there has been a lot of promotion of nasopharyngeal cancer, but everyone knows less about laryngeal cancer. In fact, laryngeal cancer is the most common throat at present. Malignant tumors are the second most common cause of cancer of the head and neck with nasopharyngeal and thyroid cancers. The age of onset is 50 to 70 years old. Long-term smokers are susceptible to the disease, said Wang Chenghua.
The third category is vocal cord paralysis caused by deafness, divided into functional and organic two, if the organic vocal cord paralysis may cause a variety of reasons, need to be checked by ENT specialists can be determined.
Laryngoscopy is required for hoarseness for two weeks
"The misdiagnosis rate of laryngeal cancer is very high, often misdiagnosed as vocal cord paralysis, chronic laryngitis, functional aphonia, etc., which is related to people's lack of understanding of sonar." Experts said.
"If it is only general inflammation, it can usually improve or recover within two weeks or so, unless there is a history of chronic laryngitis or pharyngitis and the degree is heavier." Wang Chenghua reminded that if there is unclear hoarseness, after two weeks of After symptomatic treatment, there is still no improvement, and we must pay enough attention to it. We should go to the hospital's otolaryngology clinic to undergo professional examinations such as laryngoscopy.
"If you suspect a malignancy, the doctor will also perform a biopsy and go through a pathological examination to see if there is cancer."
He introduced that clinically found that many patients with throat cancer do not pay attention to early hoarseness, until the emergence of dyspnea and other conditions aggravated before going to the hospital, so many missed the opportunity for early treatment.
"If you can carry out regular treatment in the early stage, not only can you save your life, but also can effectively retain the breathing and swallowing function." Experts said that early radiation therapy and surgical treatment of laryngeal cancer similar efficacy, cure rate of up to 90%; and laryngeal cancer Surgical treatment is mainly used, supplemented by radiation therapy and chemotherapy; advanced laryngeal cancer treatment is difficult and recovery is poor.
Chronic inflammation caused by smoking and drinking can cause laryngeal cancer
Experts said that the following categories are the causes of life that can cause laryngeal cancer:
Smoking: tobacco combustion can produce tobacco tar, which quinone can cause cancer, and tobacco smoke can stop or slow cilia movement, can also cause mucosal edema and hemorrhage, epithelial hyperplasia, thickening, squamous metaplasia, become the basis of cancer ;
Excessive alcohol consumption: long-term stimulation of the mucous membrane can cause it to degenerate and cause cancer;
Chronic inflammation: chronic laryngitis or respiratory tract inflammation may also cause cancer by prolonged repeated stimulation;
Air pollution: long-term inhalation of harmful gases such as sulphur dioxide and productive industrial dust such as chromium and arsenic can cause laryngeal cancer;
Viral infection: Viral infection is closely related to the development of cancer. It is generally believed that the virus can cause abnormal cell division in the nature of the change. The virus can attach to the gene and upload it to the next generation of cells to become cancerous.
Precancerous lesions: Laryngeal keratoses and benign laryngeal tumors, such as recurrent laryngeal papilloma, can develop cancer;
Radiation: Can cause cancer when treating neck mass with radiation;
Sex hormones: The experiments showed that the percentage of estrogen receptor-positive cells in patients with laryngeal cancer was significantly higher.
Prompt treatment of precancerous lesions can prevent cancer
"If patients with so-called precancerous lesions, such as laryngeal leukoplakia, adult laryngeal papilloma and chronic hypertrophic laryngitis, should be treated as soon as possible and reviewed regularly to avoid the development of these precancerous lesions into laryngeal cancer." Remind that for middle-aged and elderly men who have smoking and drinking habits, the promotion of smoking cessation and alcohol restriction not only can prevent laryngeal cancer, but also can avoid the occurrence of many other types of diseases in the body.
"If you use more, you should pay attention to rest. If the otolaryngolaryngologist diagnosed with benign diseases such as chronic laryngitis, laryngeal edema, etc., in addition to taking medication, rest and change voice habits are also very important to eliminate symptoms and prevent disease. If it is a professional factor that needs to be used frequently, it is recommended to eat more pears to treat throat problems.†Wang Chenghua said that pears are crisp and juicy, sweet and refreshing, and eating raw pears can significantly relieve the dry throat of patients with upper respiratory infections. Symptoms such as itching, pain, hoarseness, etc.; eating ripe pears can increase the mouth fluid, prevent dry mouth and dry lips, and protect the throat. "Summer squeezing pears into pear juice, adding fat sea, rock sugar, etc. to drink, has a certain effect on resistance to dry throat and poor pronunciation," said the expert.
