Nasal polyps CT manifestations
Nasal polyps are benign neoplasms of the nasal area. On a CT scan, they primarily appear as increased density shadows in the nasal cavity and sinus cavity. These shadows have a definite shape, which is why we see nasal polyps as oval-shaped. Secondly, the density of the nasal polyps can be distinctively differentiated from the surrounding densities; the density of the surrounding bone is very high, while the density of the nasal polyps is relatively direct, appearing as a gray density shadow. Thirdly, we observe accompanying inflammatory changes in the nasal cavity and sinus cavity on the nasal polyps, such as thickened sinus cavity mucosa and, in some cases, the presence of purulent secretions due to inflammatory infections, as seen on the CT scan.
How many days before you can speak with vocal cord polyps?
Vocal cord polyps are benign neoplasms located on the vocal cords, primarily presenting clinically as hoarseness. The formation of vocal cord polyps involves various factors, among which the most significant is the misuse of the voice. Clinically, the main treatment for vocal cord polyps is surgical removal. After the surgery for vocal cord polyps, it is important to speak less and speak normally. In fact, after the surgery for vocal cord polyps, one can speak upon waking up, but should not misuse the voice. It is crucial to speak less and avoid using a falsetto voice, as speaking in falsetto can further damage the vocal cords. Therefore, the rule to follow is to speak normally and speak less.
Can people with adenoid hypertrophy eat mangoes?
The adenoids are lymphoepithelial tissue located in the nasopharyngeal area, with adenoid hypertrophy mainly occurring in children, though it occasionally occurs in adults at a lower incidence rate. Clinically, adenoid hypertrophy is primarily caused by adverse stimulations such as allergic factors and repeated bacterial infections, with symptoms commonly including nasal congestion, snoring during sleep, and mouth breathing. For children, surgical removal is often necessary, currently performed mainly through plasma ablation. Generally, patients with adenoid hypertrophy can consume mangoes, as there are no absolute contraindications. However, if the patient also has a mango allergy, then they must avoid eating mangoes. Therefore, it is necessary to analyze each patient's specific situation.
chance of vocal cord polyps turning cancerous
Vocal cord polyps are benign neoplasms located on the vocal cords, typically presenting clinically with symptoms of a hoarse voice. Examination via electronic laryngoscopy reveals protruding polyp-like neoplasms on the free edge of the vocal cords. Clinically, malignant transformation of vocal cord polyps is rare and almost unseen. This rarity is attributed to the early presentation of hoarseness prompting patients to seek medical attention promptly, leading to early and active treatment. Therefore, clinical instances of vocal cord polyps developing into cancer are virtually nonexistent, even though theoretically possible; statistically, this likelihood is difficult to measure. In summary, it is crucial to actively address and treat vocal cord polyps upon diagnosis.
Postoperative precautions for nasal polyps
Nasal polyps are a common disease in otolaryngology, head, and neck surgery. The primary treatment for nasal polyps is functional endoscopic surgery to remove them. After the surgery, it is important to keep the following in mind: First, it is important to keep the nasal cavity clean. Clean the nasal cavity daily with saline solution and use some medications for treatment. Second, regularly visit the hospital to have the nasal cavity cleaned by the surgeon who performed the operation. Typically, the surgeon will instruct when to return for a follow-up visit, or schedule an appointment. Third, for nasal polyps, surgery is not the end of the treatment. It is generally necessary to continue daily medicinal treatment of the nasal cavity. Immediately after the surgery, it may also be necessary to take anti-inflammatory medications, such as roxithromycin or clarithromycin, for treatment. In summary, treatment and nasal cavity cleaning must continue even after surgery for nasal polyps. (Note: Please use medications under the guidance of a clinical doctor.)
Is the deviated nasal septum bone removed directly?
A deviated nasal septum refers to the cartilage or bone of the nasal septum being skewed towards one or both sides of the nasal cavities, leading to a series of symptoms such as nasal congestion, nosebleeds, and headaches. Surgical correction of a deviated nasal septum is usually carried out under nasal endoscopy. The surgery involves the removal of the deviated cartilage and bone tissue while preserving the mucosa. Since the mucosa is straight, this corrects the deviated nasal septum, thereby clearing the nasal passages. Symptoms such as nasal congestion, nosebleeds, and headaches can be effectively alleviated through surgery, so for severe cases of deviated nasal septum, surgical removal is often adopted.
What IV fluids are used for sinusitis?
Sinusitis, which we now clinically refer to as sinusitis. When sinusitis acutely flares up, our main treatment is to administer anti-infection medications and corticosteroid drugs. This includes oral medication treatment or intravenous infusion therapy. Clinically, our main approach is the aforementioned medication treatment, and we also conduct CT scans and surgical treatments based on the patient's condition, of course, assessing symptoms before proceeding. Before surgery, preoperative medication preparation is also needed, which involves some infusion therapy, using these medications, including cephalosporin antibiotics and corticosteroid drugs. (The use of medications should be carried out under the guidance of a professional doctor.)
Does throat cancer require the removal of the throat?
Laryngeal cancer is a malignant tumor in the larynx, clinically mainly squamous cell carcinoma. The treatment of laryngeal cancer primarily involves comprehensive treatment centered around surgery, which is adapted according to the type of laryngeal cancer the patient has and the extent of the lesion. For some early-stage tumors, such as carcinoma in situ or T1 stage tumors, treatment often involves local removal with a laser or radiation therapy, after which a cure is achieved without the need for partial or total laryngectomy. This approach preserves the function of the larynx, especially the function of phonation. In summary, the treatment of laryngeal cancer should be based on its specific circumstances and does not necessarily involve the removal or excision of the larynx.
Which nasal polyp spray is effective?
Nasal polyps are benign neoplasms in the nasal area, clinically manifesting as semi-opaque, lychee-shaped neoplasms. The main clinical treatment for nasal polyps includes comprehensive treatment primarily focused on surgery. In the early stages of nasal polyps, nasal sprays can be administered for treatment, primarily involving corticosteroid nasal hormones such as mometasone furoate nasal spray and fluticasone propionate nasal spray, among other nasal medications. These medications are all nasal corticosteroid hormones, and their effects are more or less the same. Clinically, no one medication is particularly more effective than another, so any of these treatments can be chosen. (Please use medications under the guidance of a doctor.)
Can you eat strawberries with suppurative tonsillitis?
Suppurative tonsillitis is a severe, acute inflammatory infection of the tonsils. Clinically, the symptoms are quite severe, with patients experiencing intense throat pain, chills, fever, etc. The clinical treatment mainly involves the use of antibiotics. The diet for suppurative tonsillitis should be nutritious, light, and easy to digest. Strawberries are a very good and tasty fruit, and generally, they can be eaten, but not in excess. This is because suppurative tonsillitis requires us to maintain a balance of cold and warm temperatures, avoiding food that is too cold or too hot. Strawberries can be consumed in moderation, not excessively. In summary, patients with suppurative tonsillitis can eat strawberries, but not too much, as strawberries are essentially a cold food.
