How long does it take to recover normally after vocal cord polyp surgery?
Vocal cord polyp surgery usually involves the use of general anesthesia and a supported laryngoscope for the removal of the polyps. This type of surgery is relatively minimally invasive, so the general recovery time for vocal cord polyp surgery is about two to four weeks. During this two to four week period, it is crucial to rest, which means vocal rest and speaking as little as possible to aid the healing of the mucous membrane after the polyp removal and to prevent mucosal edema due to excessive phonation, which is detrimental to recovery. Post-surgery phonation is a very important factor in determining the pace of recovery. If phonation is inaccurate post-surgery, or if there is excessive talking, the recovery time may be extended. If proper vocal rest is maintained and phonation is correct and careful, recovery can be quicker. Therefore, some people may recover in two weeks, while others may take more than four weeks or even longer. In addition to vocal rest post-surgery, it is essential to ensure accurate phonation. It is crucial not to speak in a subdued voice; speak normally when necessary, or do not speak at all.
Is it necessary to have surgery for vocal cord polyps?
After diagnosing vocal cord polyps, it is necessary to decide whether surgery is needed based on the size of the polyps and the effectiveness of conservative treatment. If the polyps appear large under laryngoscopy and have a broad base, and conservative treatment is judged to be ineffective, it is recommended to opt for surgical treatment as soon as possible. If the polyps are small, and the doctor assesses that there is a possibility of recovery through conservative treatment and voice rest, then conservative treatment can be initially adopted for a period of time. If after conservative treatment the vocal cord polyps have not completely disappeared, or even worsened, it is also advisable to pursue aggressive surgical treatment. Therefore, whether surgery is necessary for vocal cord polyps needs to be determined by the doctor based on the results of laryngoscopy and conservative treatment.
Symptoms of Chronic Pharyngitis
Chronic pharyngitis is a very common disease in otolaryngology, and the symptoms described by patients at the time of consultation are also diverse. The most common symptoms include dry throat, sore throat, and a foreign body sensation in the throat. Many people describe that they can neither cough it out nor swallow it down. Others say there is a feeling of obstruction when swallowing. This sensation of obstruction when swallowing refers to the feeling of blockage when simply swallowing saliva, but there is no problem with eating or drinking water, which is also called a feeling of obstruction during dry swallowing. Some people also experience notable pain, especially during acute episodes of chronic pharyngitis. Additionally, some experience nausea or retching while brushing their teeth in the morning, among other symptoms. Furthermore, pharyngitis often accompanies other primary diseases or symptoms, such as post-nasal drip, vomiting white sticky phlegm, and some people experiencing snoring during sleep, all of which are direct or indirect symptoms of pharyngitis.
How should sinusitis be treated?
The treatment of sinusitis should be based on the specific conditions of each patient, and different treatment plans can generally be divided into two categories. The first is conservative treatment. Conservative treatment mainly includes medication and some local nasal irrigation or puncture methods. This type of conservative treatment generally has good effects, and can relieve the pain and alleviate the symptoms of most patients with sinusitis. Apart from conservative treatment, The second method is surgical treatment. Surgical treatment now involves the reconstruction of nasal and sinus function under endoscopy. This type of surgical treatment can also be considered a minimally invasive and precise treatment plan. However, despite being minimally invasive and precise, it is still a surgery and does involve some trauma. Therefore, surgical treatment is only considered when conservative treatment is ineffective. Surgical treatment is just the beginning of a systematic approach to treating sinusitis. It can be understood this way: after the surgery, the follow-up medication treatment, which is a set of conservative treatment plans, and regular check-ups need to be promptly followed up. Reliance solely on surgical treatment may not achieve particularly ideal long-term effects.
What should be noted for vocal cord nodules?
Vocal cord nodules primarily require attention to speaking less and proper pronunciation as these measures address the causes of vocal cord nodules, which are due to excessive speaking and improper voicing. Therefore, these two factors need to be carefully considered. Additionally, in daily life, it's important to avoid environments with smoke and alcohol; do not smoke or inhale secondhand smoke. In terms of diet, consume light meals and avoid spicy and irritating foods. Emotionally, do not be hasty and especially avoid yelling, as there is a significant relationship between vocal cord nodules and emotional agitation or impatience.
Is adenoid hypertrophy related to rhinitis?
The adenoids are located at the rear end of the nasal cavity, specifically in the nasopharynx. When the adenoids become enlarged, they can affect the ventilation and drainage functions of the nasal cavity. Therefore, enlarged adenoids can cause rhinitis, leading to symptoms such as nasal congestion, runny nose, reduced sense of smell, and snoring during sleep; these impact the nasal ventilation, which are the most common symptoms. The rationale is that when the adenoids are enlarged, the nasal mucus cannot be normally drained through the nasal cavity's drainage function. As a result, children may exhibit symptoms of excessive nasal discharge and nasal congestion, and difficulty breathing through the nose. Additionally, the rhinitis caused by the enlarged adenoids leads to nasal congestion, which then manifests as the child snoring and breathing through the mouth during sleep. Over time, this can lead to a condition known as "adenoid facies."
Will a deviated septum get worse over time?
A deviated nasal septum generally does not worsen over time, as it is often a congenital condition. From birth, the septum develops in a skewed manner, hence the likelihood of it becoming increasingly deviated is not very high, unless significant trauma occurs during growth or later in life, which could exacerbate the deviation. In the case of normal development, the deviation does not worsen. Moreover, with the physiological development of bodily functions, the nasal septum's deviation might actually improve. However, during this period, conditions such as septal effusion and spurs could potentially lead to more severe deviations.
Is a hoarse voice an indication of throat cancer?
Hoarseness does not necessarily indicate laryngeal cancer because there are many diseases that can cause hoarseness. Common ones include vocal cord nodules, vocal cord polyps, acute laryngitis, chronic laryngitis, vocal cord grooves, and laryngeal cancer. The primary approach should be to visit an ENT (Ear, Nose, and Throat) department in a hospital, undergo an electronic fibrolaryngoscopy, and then determine the specific lesion based on the examination results. It is incorrect to diagnose laryngeal cancer based solely on hoarseness. For instance, some types of laryngeal cancer, such as supraglottic or subglottic, may cause hoarseness symptoms to appear late or even not at all. Therefore, while hoarseness does not necessarily mean laryngeal cancer, laryngeal cancer can potentially cause hoarseness. It is crucial to seek timely medical attention and undergo electronic fibrolaryngoscopy for a basic definitive diagnosis when hoarseness occurs. Apart from diseases of the throat, conditions affecting the thyroid, mediastinum, and esophagus can also cause hoarseness when they progress to a certain stage. Thus, hoarseness is a symptom that can be caused by many diseases, but it is not necessarily indicative of laryngeal cancer. Supraglottic laryngeal cancer, however, can manifest hoarseness as an early symptom. Therefore, it is critical to seek medical attention promptly once this symptom occurs.
Will there be a change in voice after vocal cord nodule surgery?
Vocal cord nodules commonly develop symmetrically at the anterior-middle third of both vocal cords. After the surgery for this condition, the hoarseness in the voice might initially worsen compared to before the surgery, particularly during the recovery period. After the surgery, it's crucial to rest the voice, meaning speaking less. Voice rest also includes proper phonation, which entails speaking correctly or not at all. It is advised to limit speaking to no more than five sentences per day. Moreover, during recovery, the voice may initially sound more hoarse than before the surgery but it should return to a state similar to that before the surgery once fully recovered. If after the surgery and subsequent recovery, the voice does not vary significantly from its pre-surgery state, this is generally the expected outcome. However, it isn't guaranteed 100%, as variations can occur depending on whether adequate voice rest was taken and whether proper phonation techniques were employed post-surgery.
Chronic Tonsillitis Dietary Precautions
In terms of diet, there are several points to note for chronic tonsillitis: First, it is very important to drink plenty of water, which is vital for the maintenance of chronic tonsillitis. As for food, it is necessary to avoid spicy and stimulating foods and primarily adopt a light diet, eating plenty of fresh vegetables and fruits to supplement vitamins in the body, which is also very important for the prevention and care of chronic tonsillitis. Additionally, try to avoid environments with smoking and alcohol; specifically, do not smoke or drink alcohol, and avoid inhaling second-hand smoke. Pay attention to oral hygiene and rinse your mouth promptly after eating.
