The difference between adenoid hypertrophy and tonsil hypertrophy.
There is a fundamental difference between adenoid hypertrophy and tonsil hypertrophy, yet there are certain connections between them. The adenoids are located in the nasopharynx and are also a lymphoepithelial organ. The nature of adenoid hypertrophy leads to an increase in size, causing obstruction of the posterior nasal apertures and the Eustachian tubes, resulting in symptoms such as snoring and otitis media. Tonsils, on the other hand, are located in the oropharynx and their enlargement can block the oropharynx, leading to rapid breathing and obstructed breathing. It is common for tonsil hypertrophy to occur physiologically in children; clinically, it is often observed that children with tonsil hypertrophy also have adenoid hypertrophy. Both generally occur together because they are part of the internal ring of the pharyngeal lymphatic ring, which establishes a link between them. In summary, while adenoid hypertrophy and tonsil hypertrophy differ fundamentally in location and the manner of pathological changes, they are connected in certain ways.
What are the symptoms of late-stage nasopharyngeal carcinoma?
Nasopharyngeal cancer is a common malignancy in otolaryngology, primarily located in the nasopharyngeal area. In advanced stages, nasopharyngeal cancer manifests symptoms in two main aspects. One involves symptoms directly caused by the cancer or its metastasis, typically presenting as increased nasal masses, enlarged cervical lymph nodes, severe headaches, decreased hearing, and bleeding in the nasal area due to tumor cells or tissue eroding the internal carotid artery. Additionally, there is a foul smell from the nasopharyngeal area. The second aspect relates to systemic symptoms due to the growth of nasopharyngeal cancer, leading to poor overall nutritional status and cachexia, characterized by extreme emaciation. There is also the potential for distant metastasis of the tumor cells, presenting symptoms in the corresponding areas.
How to Diagnose Allergic Rhinitis
Allergic rhinitis is a common and frequently occurring disease clinically. The definite diagnosis of allergic rhinitis primarily relies on the following points: First, the medical history, such as a history of living in an allergenic environment or a family history, along with a past history of the condition. Second, the clinical manifestations of allergic rhinitis, such as rhinitis, paroxysmal sneezing, a large amount of clear watery nasal discharge, and upon nasal examination, the nasal mucosa appears pale and swollen with clear watery discharge present in the nasal cavity. Additionally, supportive examinations can reveal an increase in eosinophils or lymphocytes in the complete blood count, or the detection of allergens, and specific IgE tests, etc. With these medical histories, clinical symptom manifestations, and supportive examinations, allergic rhinitis can be definitively diagnosed.
Is acute tonsillitis contagious?
Acute tonsillitis is an acute infectious inflammation of the tonsils, primarily caused by bacterial infection, though it often also involves viral infection. Acute tonsillitis is mildly contagious; the contagion is not severe or serious, and general isolation is not necessary. It is sufficient to take some precautions in daily life, such as avoiding kissing and the mouth-to-mouth transfer of food. Generally speaking, the contagiousness of acute tonsillitis is relatively weak. Appropriate use of a mask for local isolation, such as wearing a mask to prevent transmission, is sufficient without the need for other special treatments.
How to drain fluid from otitis media
Otitis media with effusion refers to the fluid in the tympanic cavity of secretory otitis media. Clinically, the methods for draining or reducing the effusion mainly include the following: First is pharmacological treatment, which primarily involves antibiotics, steroids, and medications that promote the secretion of fluids. This is the pharmaceutical approach to treatment. There is also invasive treatment, which includes procedures such as tympanocentesis, tympanostomy tube placement, and eustachian tube balloon dilation, with the aim of draining or extracting these fluids. Clinically, treatment generally begins with pharmacological approaches, followed by invasive procedures.
What should be avoided in the diet for acute tonsillitis?
Acute tonsillitis is primarily caused by an acute infectious inflammation of the tonsils due to bacterial infection, which may also initially involve viral infections. The main bacteria involved are Staphylococcus aureus and hemolytic streptococcus. The dietary restrictions for acute tonsillitis mainly include the following: Firstly, in terms of diet, it is important to eat light, nutritious, and easily digestible foods. Spicy and stimulating foods such as tobacco and chili peppers should be avoided, as these irritants can cause further congestion and swelling of the mucous membranes, exacerbating the condition during the acute phase. Secondly, attention should be given to substances such as mangoes and seafood, which can cause allergies. If a patient is allergic to these substances, consuming them can trigger allergic symptoms, aggravating the clinical symptoms of acute tonsillitis and worsening the condition. Thirdly, it is important to ensure that the food consumed is neither too hot nor too cold, as extreme temperatures can affect the recovery from the illness.
How is acute otitis media treated?
Acute otitis media is caused by bacterial infection. It is an infectious inflammation of the middle ear chamber, eardrum, or mastoid cavity. Since it is a bacterial infection, the primary treatment choice is anti-infection therapy, specifically the use of antibiotics. Currently, in clinical practice under the guidance of a doctor, cephalosporin antibiotics are mainly used. At the same time, certain antibiotic ear drops should not be used, such as ofloxacin ear drops and lomefloxacin ear drops, especially in cases of acute otitis media with severe symptoms like fever and headache. Based on the condition, we also consider anti-infection treatment through infusion. Infusion refers to the intravenous use of cephalosporin antibiotics, among others. Additionally, some corticosteroids can be used to enhance the anti-infection effects.
How to treat a deviated nasal septum?
Deviated nasal septum refers to the deviation of nasal septum cartilage and bone tissues towards one or both nasal cavities, causing symptoms such as nasal congestion, nosebleeds, and even headaches. Generally speaking, when these symptoms of nasal septum deviation occur, surgical treatment is typically adopted. This involves correcting and removing the deviated cartilage and bone tissues under endoscopic guidance to restore normal airflow in the nasal passages. If a patient only has structural or radiographic evidence of a deviated nasal septum but lacks clinical symptoms, surgery may not be necessary. Alternatively, temporary observation and medical management to control inflammation of the nasal mucosa can be considered.
Can nasal polyps be felt by touch?
Nasal polyps are benign neoplasms that occur in our nasal cavity. Clinically, nasal polyps in their early stages are primarily located in the middle nasal passage. As the nasal polyps enlarge, they can also be found in the middle nasal passage, and severe ones might even protrude from our anterior nostrils onto our face. Thus, for larger nasal polyps, we can physically feel them; they feel very soft and not very elastic. However, they are somewhat resilient and can move significantly because most nasal polyps are pedunculated within our nasal cavity. Additionally, there is often a lot of nasal mucus.
How is nasal polyps treated?
Nasal polyps are a common clinical condition, prevalent in the nasal and sinus cavities as benign space-occupying lesions. Clinically, these polyps appear as translucent, lychee-like neoplasms. The primary clinical treatment for nasal polyps is surgical, typically performed with an endoscope to remove the polyps, mainly using a powered system. After nasal polyp surgery, the treatment is not completely finished; regular outpatient follow-ups are necessary to infiltrate the nasal and sinus cavities and remove some of the swollen mucosal tissue, thus preventing the recurrence of nasal polyps.
