Which area is the most common site for laryngeal cancer?
Laryngeal cancer is a malignant tumor in the larynx, and clinically, it is primarily squamous cell carcinoma. The causes of laryngeal cancer are diverse, with major triggers being the irritation from smoking and alcohol, as well as viral infections. Clinically, laryngeal cancer is categorized into glottic cancer, supraglottic cancer, and subglottic cancer. The most common type is glottic cancer, which occurs on the vocal cords, typically affecting one vocal cord; bilateral occurrence is extremely rare. Glottic cancer, or cancer of the vocal cord area, is often detected early because hoarseness appears as soon as the lesion develops, prompting patients to seek early medical attention. Therefore, when detected early, the treatment outcomes are generally better.
The difference between rhinitis and the common cold.
There are certain differences between rhinitis and the common cold, mainly in the following aspects: Firstly, it is important to know that acute rhinitis refers to the common cold, as written in medical textbooks. However, some types of rhinitis are different, such as chronic rhinitis which is a chronic disease, not an acute illness like the common cold. Allergic rhinitis also includes symptoms such as sneezing, clear nasal discharge, and nasal congestion, very similar to those of a cold, but allergic rhinitis is an allergic disease, not a viral infection like the common cold. There are also other diseases, such as atrophic rhinitis, where the nasal cavity is very wide, whereas in a cold, caused by a viral infection, the nasal passages are very narrow, and these conditions are very different. Therefore, clinically, treatment should be based on different causes, treating colds as colds and rhinitis as rhinitis.
Does adenoid hypertrophy cause dizziness?
The adenoid is a normal tissue located in the nasopharyngeal area of the human body. Enlargement of the adenoid can block the nasopharyngeal passage, leading to various symptoms and causing dizziness. The primary reason is that adenoid enlargement can lead to snoring and mouth breathing, which affects the supply of oxygen, resulting in dizziness. Additionally, adenoid enlargement may lead to secondary sinusitis, which can also cause symptoms of dizziness and even headaches. Therefore, overall, the enlargement of the adenoid or its associated symptoms can lead to dizziness.
Can adenoid hypertrophy heal itself?
The adenoids are normal lymphoepithelial tissue located in our nasopharynx. In young children, especially around the ages of 5-6, the adenoids become enlarged or hyperplastic. This can then easily lead to the obstruction of surrounding structures causing issues such as snoring, sinusitis, and otitis media. Generally, adenoid hypertrophy is self-resolving because, after the age of around ten, the adenoids gradually atrophy. However, there are a minority of patients in whom the adenoids do not atrophy. Although the adenoids of the vast majority of patients will atrophy around the age of ten, it is important to recognize that from hypertrophy to atrophy, there is a long duration during which if deformities or conditions that affect body development occur, they cannot be reversed to normal. Therefore, it is essential to treat and intervene timely in patients with adenoid hypertrophy.
Can vocal cord polyps be treated without surgery?
Vocal cord polyps are benign neoplasms in the throat, primarily presenting clinically as hoarseness. Typically, vocal cord polyps are relatively large when detected, and various treatment methods often do not result in complete disappearance. Therefore, clinical treatment of vocal cord polyps mainly involves surgical removal. Sometimes, if patients are reluctant to undergo surgery, medication can be attempted. However, the likelihood of completely eliminating vocal cord polyps with medication alone is relatively low. If the condition does not improve or the polyps do not shrink or disappear after medicinal treatment, surgery is often necessary.
Will turbinates that have been removed grow back?
Enlarged turbinates primarily refer to the enlargement of the inferior turbinates, and in rare cases, the middle and superior turbinates may also become enlarged. Clinically, the enlargement of the inferior turbinates is mainly caused by various chronic inflammatory stimuli in the nasal area, leading to nasal congestion, impaired secretion of nasal mucus, and even symptoms such as headaches in patients. Clinically, for turbinates, minimally invasive treatment methods are mainly used, such as plasma volume reduction surgery and submucosal partial resection of the inferior turbinates. Generally speaking, once the turbinates are removed, they cannot regrow; only the surface mucosa can regrow, but the turbinate bone cannot regrow. Therefore, after the removal of the turbinates, there is a significant increase in the spaciousness of the nasal cavity, which is beneficial for improving the patient's symptoms of nasal congestion.
Adenoid hypertrophy should be seen by the ENT department.
The glandular body, located in the nasopharyngeal region, is an organ made up of lymphoepithelial tissue. Enlargement of the glandular body leads to an increase in its size, blocking the passage of the nasopharynx. Based on this explanation, it is understandable that glandular hypertrophy should be evaluated by an otolaryngologist. If a more detailed subdivision of specialization is necessary, it can be divided into rhinology, laryngology, and otology, with the main focus being on rhinology or laryngology depending on the specific regulations of different hospitals. In summary, glandular hypertrophy should be assessed by an otolaryngologist. Additionally, it is important to note that glandular hypertrophy can lead to developmental abnormalities, especially in dental development. If these complications occur, consultation with the relevant departments, such as dentistry, may be necessary.
Can people with chronic rhinitis eat eggs?
If chronic rhinitis is simply hypertrophic or atrophic, these types of rhinitis generally allow for the consumption of eggs without much hindrance. However, if the chronic rhinitis is triggered by allergic factors, then if the patient is allergic to eggs, they must not consume eggs. Even if not allergic to eggs, given that eggs are a food containing large molecular proteins which can easily trigger other allergies, their consumption should be limited. In summary, aside from allergic diseases, other types of chronic rhinitis do not restrict the consumption of eggs.
How is advanced malignant throat cancer treated?
Laryngeal cancer is a malignant tumor in the larynx, mainly squamous cell carcinoma. In advanced stages of laryngeal cancer, the main issues are malignant ulcers in the laryngeal area, followed by tumor proliferation, bleeding, and then blockage of the airway by the tumor mass, leading to respiratory difficulties and cachexia throughout the body. Therefore, the primary treatment for advanced malignant tumors is to maintain airway patency, mainly through tracheotomy; secondly, pain management and analgesic treatment are provided to improve the patient’s quality of life; thirdly, nutritional support is provided to the patient, including the insertion of a gastric tube or even parenteral nutrition via intravenous feeding. Overall, the treatment of advanced malignant tumors primarily focuses on improving quality of life and alleviating patient suffering.
Can nasal polyps be operated on in the outpatient clinic?
Nasal polyps are benign neoplasms in the nasal cavity. Pathologically, nasal polyps are benign tumors. Clinically, the primary treatment is the surgical removal of nasal polyps followed by regular outpatient follow-ups to prevent recurrence. Currently, the surgery for nasal polyps is generally performed under general anesthesia, involving the removal of nasal polyps and sinus opening procedures, which are functional surgeries. Such surgeries require hospitalization and are conducted under endoscopy, typically under general anesthesia. Although in some regions, the surgery may be performed under local anesthesia, hospitalization is still required for the procedure, and it is generally not conducted on an outpatient basis.
