Do vocal cord polyps require a biopsy?
Vocal cord polyps are benign neoplasms located on the vocal cords, typically protruding from the surface or the free edge of the vocal cords. Therefore, the removal surgery for vocal cord polyps is generally performed under laryngoscopic and microscopic visualization. The procedure usually involves direct excision followed by pathological examination, and a biopsy is generally not conducted before the surgery. Thus, vocal cord polyps are typically treated through direct surgical removal without a pre-surgery biopsy. It is also important to avoid excessive misuse of the voice after the surgery to prevent recurrence of the vocal cord polyps.
What does it mean when nasal polyps bleed?
Nasal polyp bleeding mainly has three causes. One reason is that the nasal polyp damages the structure of the nose. Since nasal polyps are a space-occupying lesion, they gradually enlarge, compress the nasal structures, and damage the mucosa and blood vessels of the nose, which can lead to nasal bleeding. The second reason is that the nasal polyp itself may be a bleeding necrotic nasal polyp. This type of bleeding necrotic nasal polyp is very prone to bleeding, and even minor injuries or damage can lead to bleeding. The third reason is that bleeding necrotic nasal polyps might be a manifestation of the disease. As the nasal polyp enlarges, if such an enlarged polyp becomes lodged in a sinus opening or in the nasal cavity, it can lead to ischemic necrosis, which after occurring, can cause bleeding. In summary, these are the three main cases.
Does adenoid hypertrophy cause yellow nasal discharge?
The glands located in our nasopharyngeal area are immune tissues. Enlargement of these glands can lead to an increase in their size, which may block our posterior nasal apertures. Consequently, the secretions in our nasal cavity cannot be properly discharged. This may eventually lead to spontaneous infections causing sinusitis, characterized by the discharge of yellow nasal mucus. Thus, there is a direct relationship between the occurrence of sinusitis in children and the enlargement of these glands. Clinically, it can be observed that after surgery for gland enlargement, the symptoms of sinusitis and the discharge of yellow nasal mucus are significantly reduced or even completely cured. Therefore, it can be said that there is a direct relationship between gland enlargement and conditions such as rhinitis, sinusitis, and the discharge of yellow nasal mucus.
Can I eat biscuits with acute pharyngitis?
Acute pharyngitis is an acute inflammatory disease of the pharynx, clinically characterized by soreness in the throat and sometimes symptoms such as chills and fever. Examination can reveal acute congestion of the pharyngeal mucosa, and the mucosa may also be edematous. Theoretically, it is permissible to eat biscuits during acute pharyngitis, as there are no specific contraindications. However, biscuits are generally dry and can be difficult to swallow because of the soreness in the throat during acute pharyngitis. If one must eat biscuits, they can be chewed thoroughly or dipped in water, and there are no absolute contraindications. It is important for patients with acute pharyngitis to maintain a light diet and drink plenty of water, but eating biscuits is allowable.
Is correction of nasal turbinate hypertrophy a surgical procedure?
Enlarged turbinates are a common clinical sign, primarily caused by chronic inflammation in the nose and deviations in the nasal septum. Clinically, surgeries targeted at correcting enlarged turbinates are primarily conducted. Main approaches include: One method is the fracturing and outward movement of the turbinate bone; another is the excision of the submucosal part of the enlarged turbinate. Other treatments, such as plasma ablation therapy for the turbinates, are also viable. The specific treatment method should be chosen based on a facial examination, observations of the specific condition of the enlarged turbinates, as well as assessments from sinus CT scans and conditions of the turbinate bones.
Can people with chronic rhinitis and chronic pharyngitis eat chicken?
Chronic rhinitis and chronic pharyngitis are chronic inflammatory diseases of the upper respiratory tract, which can be caused by either prolonged acute inflammation that has not healed or by various inappropriate chronic stimulations. Generally, patients with chronic rhinitis and chronic pharyngitis can eat chicken, which is clear. However, if the patient has allergic factors, such as an allergic constitution specifically allergic to chicken, then chicken should not be eaten. Regarding the consumption of chicken in the context of these chronic inflammations, it is important to consider appropriate cooking methods; it should be light. Spicy and stimulating cooking methods are not suitable for patients with chronic rhinitis and chronic pharyngitis. All in all, under normal circumstances, patients with chronic rhinitis and chronic pharyngitis can consume chicken, but in special cases, caution is necessary.
How long does it take to wake up from general anesthesia for vocal cord polyps?
Vocal cord polyps are common and frequently occurring clinical benign tumors located on the vocal cords. Clinically, the main treatment is the removal of the vocal cord polyps under a microscope-assisted laryngoscope, performed under general anesthesia. Currently, our control technique for general anesthesia is very refined, and the surgery for vocal cord polyps generally takes about 15 minutes. After these 15 minutes, our patients gradually regain consciousness. Therefore, patients undergoing general anesthesia for vocal cord polyp surgery can progressively wake up after the surgery is complete. This is achievable due to our current precise control techniques in anesthesia and medication management, allowing patients to awaken promptly after the surgery.
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.
