Etiology of chronic tonsillitis
Chronic tonsillitis is a chronic inflammatory disease of the tonsils, which can arise from two sources. One is due to the repeated occurrences of acute inflammation of the tonsils, incomplete healing, poor physical constitution of the patient, or strong infectiousness of bacteria, resulting in unresolved, lingering chronic inflammation. In this case, the tonsils undergo recurrent acute flares on the basis of chronic inflammation, leading to the chronicity of the inflammation that cannot be cured. Another possible scenario for the onset of this tonsillitis is that it begins as a chronic inflammation. This is mainly due to a bacterial infection that is either not severe or a chronic latent infection. Therefore, the inflammation of the tonsils does not show obvious acute inflammatory signs but exhibits signs typical of chronic inflammation, primarily due to these two reasons.
Nasal polyps are located where?
Nasal polyps are benign neoplasms in the nasal area, forming a translucent, lychee-like shape with no distribution of nerves or blood vessels. They originate from two sources: one from the nasal cavity and the other from the nasal sinuses. Theoretically, any part of the nasal cavity and sinuses can develop nasal polyps or polyp-like changes. The most common nasal polyps primarily originate from the middle nasal meatus, while those from the sinuses mainly stem from the ethmoid or maxillary sinuses, which are the most common and prone areas. Clinically, the treatment for nasal polyps mainly involves removal via endoscopic surgery and the opening of the sinuses.
Why do vocal cord polyps bleed?
Vocal cord polyps are a cold-natured and space-occupying lesion located on the vocal cords, usually occurring unilaterally. Clinically, they primarily present as hoarseness. Examination can reveal a polyp-like neoplasm protruding from the surface of one vocal cord. There are two reasons for bleeding in vocal cord polyps. One is intense coughing or other mechanical injuries that cause bleeding on the surface of the polyp, due to damage to the vocal cord mucosa, among other factors. The second is that these polyps are hemorrhagic, possessing a rich supply of blood vessels, referred to as hemorrhagic polyps, which are prone to bleeding. Another scenario is post-surgical bleeding due to mucosal damage, friction, or other factors following surgery for vocal cord polyps, primarily involving these three factors.
What medicine is good for enlarged adenoids?
Adenoid hypertrophy is a common and frequently occurring disease in the field of otolaryngology head and neck surgery. Clinically, adenoid hypertrophy is mainly treated through surgical removal, which is typically performed under endoscopic guidance using techniques such as plasma surgery. As for its clinical drug treatment, it should be noted first that there are no drugs specifically targeting adenoid hypertrophy. The drugs currently used, such as mometasone furoate nasal spray and montelukast sodium, are aimed at treating allergic factors related to adenoid hypertrophy. These drugs have some effects, but their efficacy is relatively poor, and only a small portion of patients achieve certain therapeutic effects. Therefore, if adenoid hypertrophy causes secondary diseases such as snoring, otitis media, or sinusitis in patients, it is still necessary to proceed with active surgical treatment. (Specific medications should be used under the guidance of a physician)
Will nasal polyps grow back after being removed?
Nasal polyps are a common and frequently occurring clinical condition, representing benign neoplasms of the nasal cavity. Currently, the primary treatment for nasal polyps is their removal via endoscopic surgery, generally accompanied by surgery to open the sinus cavities. After nasal polyp surgery, there is a certain rate of recurrence, so measures must be taken to reduce this recurrence, such as regular post-operative clinic visits to clean the nasal and sinus cavities. Additionally, aggressive medication treatments are required after surgery, such as the use of budesonide nasal spray, along with other supportive medications. During surgery, it is crucial to remove the roots of the nasal polyps as thoroughly as possible and also to remove the diseased mucosal tissues as much as feasible. (Medication should be used under the guidance of a clinical doctor, based on the specific circumstances.)
Septal deviation resection
Deviated nasal septum is a common and frequently occurring condition in our department of otorhinolaryngology and head and neck surgery. It refers to the cartilage and bone of the nasal septum deviating towards one or both sides of the nasal cavities, leading to clinical symptoms such as nasal congestion, nosebleeds, and headaches. Typically, a CT scan is conducted to determine the extent of the deviation, and then, combined with clinical symptoms, surgery is performed to correct the deviated nasal septum. The surgery mainly involves removing the deviated cartilage and bone, and then repositioning the nasal septum to a central position, thus eliminating the symptoms caused by the deviated nasal septum.
When is a good age to have surgery for adenoid hypertrophy?
The reason adenoid hypertrophy requires surgical treatment is because it blocks the passage of our nasopharynx, leading to nasal congestion and snoring, affecting body and jawbone development, and even causing otitis media which can impair hearing. There is no absolute age requirement for adenoidectomy; surgery is an option if these complications are present. Clinically, we generally consider the size of the adenoid and whether it causes complications, along with the patient's actual age. Typically in our clinical practice, surgery is usually considered after the child is two and a half years old, as long as the symptoms and hypertrophy are present. It is important to understand that adenoid hypertrophy is quite common around the ages of 6 to 7 years, when the enlargement peaks, making adenoidectomy a common procedure for children of this age group.
How is otitis media treated?
Otitis media is a common and frequently occurring disease in the field of otolaryngology head and neck surgery. The treatment of otitis media is divided into acute and chronic. The clinical treatment of acute otitis media mainly involves anti-infection treatment, primarily using antibiotics locally or systemically, such as ofloxacin ear drops, cephalosporin antibiotics, and, if necessary, intravenous anti-infection treatment. Chronic otitis media is mainly treated surgically in clinical settings. The surgical treatment involves repairing structural defects, removing diseased structures, and restoring normal sound transmission structures. (Medications should be used under the guidance of a clinical physician and based on the specific situation.)
What medicine is used for adenoid hypertrophy?
The adenoids are normal anatomical structures located in the nasopharynx. In childhood, the glandular tissue of the adenoids becomes enlarged, blocking the normal passages of the nasopharynx and leading to secondary diseases. Clinically, there are no drugs specifically targeting enlarged adenoids. However, other medications, such as mometasone nasal spray and montelukast sodium, may have some effect on adenoid enlargement and can help a minority of patients avoid surgery. Nonetheless, it is advised not to rely on these drugs as the primary treatment method for enlarged adenoids; the main treatment is surgical.
Can you eat fish with vocal cord nodules?
Patients with vocal cord nodules who do not have an allergic constitution can eat fish. Vocal cord nodules are benign growths on the surface of the vocal cords, typically occurring bilaterally and symmetrically, mainly characterized by hoarseness. Their development is primarily associated with improper voice usage or long-term vocal abuse. For vocal cord nodules, patients are advised to talk less and maintain a light diet. Patients with vocal cord nodules can eat fish, but we must prevent some patients from doing so because some of them have an allergic constitution. Fish is a high-protein food, and consuming it may trigger allergic reactions in these patients. The onset of an allergic reaction can also lead to congestion and swelling of the vocal cord mucosa, further worsening the hoarseness and aggravating the condition of the vocal cord nodules. Therefore, it is best for these patients to avoid eating fish.
