Voices
What does it feel like to have vocal cord polyps?
Vocal cord polyps generally do not cause any special sensations by themselves, but some patients may experience pain, stiffness, and fatigue. The main symptom is a hoarse voice, meaning the voice becomes raspier than before, making it difficult to articulate, especially when trying to sing or speak in high tones. In addition to hoarseness, other symptoms can include a feeling of vocal fatigue, throat pain, and an irritating cough. However, these symptoms can vary from person to person, with hoarseness being the primary manifestation.
The best treatment method for vocal cord nodules
Vocal cord nodules are often caused by excessive talking, loud speaking, or overuse of the voice. They are commonly found in individuals who frequently use their voices in their professions, such as salespeople, teachers, and singers. The best treatment approach is to address the root cause, which involves speaking less and using proper vocal techniques. This is the optimal treatment plan. However, this method may not always be effective, as some people, due to their occupational needs, cannot fully achieve vocal rest. If vocal rest does not effectively treat the condition, surgical intervention may then be necessary. During the treatment period, after diagnosing vocal cord nodules, vocal rest is the preferred approach. If vocal rest is ineffective or does not fully resolve the nodules, surgery may be required as a follow-up treatment.
How to completely cure chronic tonsillitis?
The definitive treatment for chronic tonsillitis mainly involves surgical removal. Before undertaking the surgery, doctors will conduct a strict assessment to see if there are indications for surgery. Common indications include repeated episodes of chronic tonsillitis, acute outbreaks, or the formation of a peritonsillar abscess, under which circumstances surgery is strongly recommended. Repeated episodes are defined as more than four occurrences per year, at which point surgery should be considered. Furthermore, if the tonsils are so large that they interfere with swallowing, speech, or breathing, such as causing snoring or unclear speech, surgery should also be considered. Moreover, chronic tonsillitis can lead to other diseases since the tonsils are an immune organ, and prolonged chronic inflammation might trigger certain immune-related diseases, such as chronic nephritis, skin diseases, and psoriasis. In such cases, the relevant departments will advise patients to first visit an otolaryngology (ENT) department to have the tonsils removed, which is beneficial for further treatment of the related diseases. Additionally, if the tonsils exhibit signs of benign growths with chronic inflammation leading to lymphatic tissue hyperplasia and cyst formation, surgical removal is recommended to achieve a definitive cure.
Vocal cord nodules are caused by what?
Vocal cord nodules are mainly caused by improper speaking, excessive speaking, emotional excitement, and shouting. The most common symptom of vocal cord nodules is a hoarse voice. This condition is often seen in people who speak a lot, such as teachers, salespeople, and singers. These include individuals who tend to shout, are impatient, and speak improperly. Such cases are commonly seen in clinics, especially among children. For example, children who shout and speak carelessly at school during the semester may develop vocal cord nodules with hoarseness as a symptom. Additionally, emotionally excitable and impatient people can develop nodules. Some grandparents, who often yell at their children at home, also tend to develop vocal cord nodules. In summary, those who speak too much, shout, mispronounce sounds, or are emotionally excitable are at risk of developing vocal cord nodules.
Does a deviated nasal septum need to be treated?
Deviated nasal septum is a common clinical occurrence in otolaryngology, and many people are told they have a deviated septum during a physical examination, or they feel uncomfortable with their nose and then find out they have a deviated septum when checking. Whether to treat these conditions depends on the specific circumstances. If there is no discomfort in the nose, breathing is normal, the sense of smell is unaffected, and there are no other clinical symptoms, surgery is unnecessary for a deviated septum discovered during a physical examination. However, if there are uncomfortable symptoms caused by the nasal cavity or deviated septum, and after examination, the doctor confirms that these are due to the deviated septum, then active surgical treatment is necessary. Only by correcting the deviated part can a satisfactory treatment outcome be achieved.
Can a deviated nasal septum be left untreated without surgery?
Whether or not surgery is needed for a deviated nasal septum ultimately depends on the individual's specific symptoms and the extent of the deviation. This condition, which is a very common congenital developmental abnormality, can also be caused by postnatal trauma. Deviations are very common in the human body, but not everyone requires surgery. The diagnosis of a deviated nasal septum mainly considers whether the extent of the deviation affects function or appearance, that is, whether it causes pathological changes. If the nasal septum deviation does not cause functional changes or affect appearance, then surgery is not necessary. If it causes nasal congestion or leads to complications such as rhinitis or sinusitis, or affects appearance, then surgical treatment should be considered. Therefore, whether surgery is needed for a deviated nasal septum should be based on the severity and the presence of related clinical symptoms.
Symptoms of acute pharyngitis
The symptoms of acute pharyngitis are multifaceted. Initially, the onset of the disease is quite sudden. The main symptoms start with dryness, heat, and liver pain, which is the most common description by patients. Furthermore, there is a sensation of a foreign object in the throat, leading to exacerbated pain when coughing. This pain is particularly noticeable during swallowing, making it difficult to even eat or swallow saliva. Additionally, this pain can radiate to the sides, commonly causing ear pain when chewing or eating, resulting in both throat and ear pain. Systemic symptoms can resemble those of a cold, such as mild fever, high body temperature, headache, loss of appetite, and general weakness.
Symptoms of chronic pharyngitis flare-ups
The symptoms of chronic pharyngitis mainly include the following points. The first is a foreign body sensation in the throat. This sensation in the throat is a subjective feeling of the patient, often most noticeable when swallowing saliva, that is, when the throat is otherwise empty. However, there is no significant obstruction when eating or drinking, which is a typical clinical feature and characteristic of chronic pharyngitis caused by a foreign body sensation in the throat. The second symptom is pain in the throat. When chronic pharyngitis is triggered by certain adverse stimuli, there can be a sensation of pain in the throat, as well as nausea. Many people with chronic pharyngitis experience nausea and vomiting, especially in the morning when brushing their teeth or upon waking, which stimulates movement in the throat.
How is chronic tonsillitis treated?
The treatment of chronic tonsillitis mainly involves two aspects. The first is conservative treatment, which means paying attention to regular physical exercise to enhance the body's resistance, avoiding environments with smoke and alcohol, and avoiding spicy and irritating food. The purpose of this approach is to prevent acute attacks of chronic tonsillitis. The other method is surgical treatment. Surgical treatment requires adherence to certain criteria for chronic tonsillitis surgery, commonly including repeated occurrences of more than four times a year, the formation of peritonsillar abscesses, and cases affecting breathing, phonation, or swallowing functions. Additionally, surgery is needed when chronic inflammation of the tonsils leads to conditions such as inflammatory granulomas or hyperplasia.
Deviated nasal septum has symptoms such as:
Symptoms caused by a deviated nasal septum vary widely, with some people experiencing predominantly one symptom, while others may have several symptoms simultaneously. The most common symptom is nasal congestion, which can be unilateral or bilateral, depending on the type and degree of the septal deviation. If the deviation affects both sides of the nasal cavity, bilateral congestion occurs; if it affects only one side, unilateral congestion occurs. Another symptom is recurrent nosebleeds, which may be related to a protrusion formed by the deviation, causing the mucous membrane at that location to be thin and prone to erosion and bleeding. Additionally, headaches can occur due to the nasal septum deviation irritating the nasal nerve. Other symptoms include those of secondary conditions such as a runny nose and mouth breathing.
