Difference between Allergic Rhinitis and Rhinitis
Allergic rhinitis and rhinitis are issues of a specific concept versus a broader concept. Allergic rhinitis is a type of rhinitis caused by a hypersensitivity reaction, which is an allergic response of the body leading to inflammation of the nasal passages. Rhinitis, however, includes allergic rhinitis as well as chronic rhinitis, hypertrophic rhinitis, vasomotor rhinitis, atrophic rhinitis, etc. Thus, it's a matter of differentiating between a more specific and a general concept. Clinically, it is particularly important to differentiate their diagnosis and treatment. For example, the primary treatment for allergic rhinitis is anti-allergy medication, whereas treatments for conditions like chronic and atrophic rhinitis are completely different. Therefore, it is crucial to differentiate these accurately in clinical practice to ensure the correct medication is used.
Can nasal polyps be eliminated?
Nasal polyps are benign neoplasms in the nasal cavity. They are translucent, lychee-shaped neoplasms without nervous or vascular innervation. Nasal polyps can be completely removed, primarily through two methods. One method is the chemical removal with medications, mainly using corticosteroids, which is suitable for early-stage nasal polyps. Another method is via functional endoscopic sinus surgery, which involves the removal of nasal polyps. The surgery is performed under endoscopic guidance, using forceps or a snare device to excise the nasal polyps. This surgery is conducted under general anesthesia, and nasal polyps can be removed.
Can nasal polyps be treated with laser?
Nasal polyps are benign neoplasms of the nasal cavity or sinus cavity. The current treatments for nasal polyps include medication and endoscopic surgical removal. Clinically, lasers like the CO2 laser are primarily suited for precise operations. Nasal polyps are generally quite large, so lasers are typically not used for their treatment. Clinically, a suction cutter is mainly used to remove nasal polyps. Previously, when less advanced and without suction cutters, lasers might have been attempted, but now lasers are basically no longer used for treatment because their indications do not align with those for nasal polyps.
Difference between the symptoms of laryngitis and throat cancer
There is a fundamental difference between laryngitis and laryngeal cancer. Laryngitis is an inflammatory infectious disease, mainly caused by bacterial infection or chronic inflammatory conditions, clinically characterized primarily by hoarseness. Treatment is mainly through medication, such as oral medications or nebulized inhalation therapy. Laryngeal cancer is a malignant tumorous disease, primarily squamous cell carcinoma. Clinically, in addition to hoarseness, we can also observe tumorous lumps and swelling of the cervical lymph nodes, which are manifestations of malignant tumors. The treatment of laryngeal cancer primarily involves comprehensive treatment led by surgery, including surgery, radiotherapy, chemotherapy, and some biological treatments, etc. Therefore, there is a fundamental difference between the two.
Does otitis media require hospitalization?
Otitis media refers to the acute or chronic inflammatory disease of our middle ear, mainly caused by bacterial infection. For otitis media, whether it is acute or chronic, hospitalization is rarely considered. The vast majority of treatments do not require hospitalization; treatment typically involves outpatient anti-infection therapy. However, if complications arise in otitis media, such as tympanic membrane perforation, disruption of the ossicular chain in the middle ear, granulation in the mastoid cavity, or cholesteatoma, then hospitalization and surgical treatment are considered. The purpose of surgery is mainly to repair structures and clear pathological tissues. In summary, for otitis media, hospitalization for surgical treatment is considered only when necessary; otherwise, inpatient treatment is not required for medical treatment.
What are the symptoms of nasopharyngeal carcinoma?
Nasopharyngeal carcinoma is a malignant, space-occupying lesion in our nasopharynx. Clinically, the initial symptoms are those of the nasopharynx, manifesting as discomfort in the nasopharyngeal area, or blood in nasal discharge when sniffling. As the nasopharyngeal carcinoma tissue enlarges, it can block the posterior nasal apertures, leading to nasal congestion, rapid breathing, and difficulty in breathing. The tumor tissue pressing on our Eustachian tube can cause secretory middle ear infections. The metastasis of nasopharyngeal carcinoma cells to our cervical lymph nodes causes swelling of these lymph nodes. Destruction of the cranial structure by nasopharyngeal carcinoma tissues presents symptoms such as headaches. There are also other symptoms, mainly due to the spread of nasopharyngeal carcinoma throughout the body or its metastasis to other parts causing corresponding symptoms.
The difference between sinusitis and rhinitis
Rhinitis and sinusitis are common inflammations in our nasal area, frequently occurring and widely prevalent. Rhinitis primarily involves inflammation of the nasal mucosa, while sinusitis specifically refers to inflammation in the sinus cavities and their mucous membranes. These two have different locations of onset. Furthermore, rhinitis is more commonly seen clinically compared to sinusitis, which is less common relative to rhinitis. Moreover, rhinitis is generally treated with medication and seldom requires surgical intervention. In contrast, sinusitis may also require surgical treatment besides medication. Thus, the main differences between them primarily include these aspects. Overall, the fundamental difference between rhinitis and sinusitis lies in their different locations of onset.
Does sinusitis require surgery?
Sinusitis refers to inflammation of the sinus, clinically mainly bacterial inflammation, as well as fungal inflammation. Whether sinusitis requires surgery depends on the specific condition of the patient. Endoscopic examination of the nose and sinus CT scans can be carried out to assess the condition of the sinus lesions. If there is a lot of sinus secretion and the sinus cavity is congested, and there is polypoid changes in the overall nasal passage, surgical treatment may be considered. For the vast majority of sinusitis patients, the current viewpoint is that treatment is mainly through medication, and only a small part needs surgical treatment after assessment. Therefore, sinusitis does not necessarily require surgery. Start with medication treatment; if the effect is not good, or there are other concurrent issues, consider surgical treatment after assessment.
How is adenoid hypertrophy surgery performed?
The adenoid is a lymphoepithelial tissue located in the nasopharyngeal region. Enlargement of the adenoid can block the nasal passages, leading to snoring and sleep apnea, often requiring surgical removal of the adenoid. The surgery is performed under general anesthesia. Firstly, we use a catheter to suspend the soft palate to expose the adenoid tissue. Then, using a nasal endoscope, with the right hand holding a plasma knife, the enlarged adenoid is ablated. The surgery involves inserting the nasal endoscope and adenoid knife through the mouth. The procedure is relatively short, lasting about five to ten minutes. There is very little bleeding after the surgery, making it truly a minimally invasive procedure.
How is nasopharyngeal carcinoma diagnosed?
Nasopharyngeal carcinoma is a malignant, occupying lesion that occurs in the nasopharyngeal area, and clinically it is mainly squamous cell carcinoma. Relatively speaking, although this tumor is malignant, its degree of malignancy is relatively low, especially when compared to liver cancer, lung cancer, and other malignant tumors. The definitive diagnosis of any tumor primarily relies on histopathological diagnosis, which means that pathological examination is the gold standard. In the case of nasopharyngeal carcinoma, we can make a pathological examination by using nasopharyngeal biopsy tissue with forceps under nasendoscopy. If cancer cells are found, then it is essentially confirmed. Of course, other examination methods, such as CT and MRI, are also helpful in diagnosing nasopharyngeal carcinoma and determining whether there are any metastases.
