Can adenoid hypertrophy be seen with the naked eye?
Adenoid hypertrophy is not visible to the naked eye because the adenoids are located on the posterior wall of the nasopharynx. It can only be detected through an electronic nasopharyngoscope or a CT scan of the nasopharynx to determine if there is adenoid hypertrophy. Adenoid hypertrophy is most likely to occur during childhood, typically due to long-term inflammatory infections. It often follows acute rhinitis or acute sinusitis. After adenoid hypertrophy, it can lead to bilateral nasal congestion that progressively worsens, along with snoring during sleep, tinnitus, a feeling of ear congestion, and a decrease in hearing. In severe cases, it can lead to a characteristic facial appearance known as "adenoid facies." It is necessary to have a detailed examination at a hospital for adenoid hypertrophy. An electronic nasopharyngoscope and adenoid CT can confirm the diagnosis. For treatment, during the acute phase of adenoid hypertrophy, symptomatic anti-inflammatory treatment is necessary, along with the use of nebulized inhalation to reduce congestion and swelling of the adenoids. If conservative treatment is ineffective and the adenoid hypertrophy continues to worsen, adenoidectomy may be required to completely cure the condition.
Can a deviated nasal septum undergo rhinoplasty?
A deviated nasal septum is a contraindication for rhinoplasty, as undergoing the procedure can lead to a skewed nasal bridge. Deviated nasal septum is a common and frequently occurring condition in otolaryngology, generally related to abnormalities in the development of the nasal septum during embryonic stages or to acquired trauma to the nasal septum. A deviated nasal septum can lead to symptoms such as a crooked nasal bridge, persistent nasal congestion on both sides, facial swelling, pain, and headaches. It is necessary to visit a hospital for a thorough examination using an endoscope and sinus CT scan to confirm the diagnosis. During the examination, the nasal septum may be found to be deviated to one or both sides in an S-shaped or C-shaped curve. In terms of treatment, a mild deviated nasal septum may not require any intervention. However, if the patient experiences nasal congestion, headaches, and other related symptoms, local surgical treatment is necessary. Only after the nasal septum is centrally aligned through surgery, can rhinoplasty be considered.
How long after septoplasty under general anesthesia can one get out of bed?
After general anesthesia surgery for a deviated nasal septum, patients can freely move in bed after 6 hours, but should wait at least 24 hours before getting out of bed and moving around to avoid the effects of the anesthesia. A deviated nasal septum is a common and frequently occurring condition in otolaryngology, typically caused by congenital abnormalities in the development of the nasal septum. This condition may lead to persistent, progressive nasal congestion on both sides, along with pain in the facial area, headaches, and a deviated nasal septum. It can also trigger nasal sinusitis and nasal polyps in patients. A detailed examination at the hospital with an electronic nasal endoscope and sinus CT scan can provide a diagnosis. In terms of treatment, if a mild nasal septum deviation presents no clinical symptoms, no treatment is necessary. However, if the patient suffers from nasal congestion, headaches, or other related symptoms, local surgical correction may be required. Patients typically recover and are discharged about a week after the surgery.
Can vocal cord polyps disappear on their own?
Vocal cord polyps cannot disappear on their own because they are a benign tumor. Without local surgical treatment, vocal cord polyps will continue to grow, causing the patient's hoarseness to worsen further. In severe cases, it can cause the patient to have breathing difficulties, leading to choking and even death. Vocal cord polyps are caused by improper use of the voice over a long period, such as yelling loudly or excessive tiredness, leading to pathological changes in the vocal cord mucosa. They can cause persistent hoarseness in patients. During an examination with an electronic laryngoscope, a smooth, light red or pale white abnormal neoplasm can be found on the anterior-middle third of one vocal cord. The vocal cord moves well, but does not close completely. In terms of treatment, patients need to undergo local surgical excision to heal. After surgery, it is important to protect the vocal cords by avoiding yelling loudly or speaking entirely, and complete recovery can generally be achieved within about a week.
Is nasal discharge a sign of improvement in adenoid hypertrophy?
Enlargement of the adenoids accompanied by a runny nose is not a sign of improvement but a symptom of worsening. Enlargement of the adenoids is primarily due to symptoms caused by acute viral or bacterial infections following a decrease in the body’s immunity and resistance. This can lead to diffuse congestion and edema of the glands, causing the patient to experience persistent nasal congestion and discharge of yellow nasal mucus. In severe cases, it can cause nocturnal suffocation. Initially, a detailed examination at the hospital is necessary. Diagnosis can be confirmed with an electronic nasopharyngoscope and a nasopharyngeal CT. During the examination, granular masses can be found on the posterior wall of the nasopharynx; these are soft in texture and not painful. In terms of treatment, during the acute phase of adenoid hypertrophy, symptomatic anti-inflammatory treatment is required, including the use of antibiotics and concurrent nebulizer inhalation to reduce congestion and edema of the adenoids. If the enlargement persists and conservative treatment is ineffective, adenoidectomy may be necessary to achieve a complete cure.
Is a deviated septum related to wearing glasses?
Deviated nasal septum has no relation to wearing glasses. Deviated nasal septum is a common and frequently occurring condition in the field of otolaryngology. It is directly related to developmental abnormalities of the nasal septum during the embryonic stage, or due to trauma to the nasal septum and pressure from nasal tumors. A deviated nasal septum can lead to persistent nasal congestion and headaches. Additionally, it may also trigger sinusitis and nasal polyps in patients. Minor deviations in the nasal septum do not require any clinical treatment. However, if a patient experiences severe nasal congestion, headaches, and other related symptoms, it is necessary to visit a hospital for corrective surgery for the deviated nasal septum. A prior examination using an endoscope and sinus CT scan is needed to assess the extent of the deviation. After the surgery, it is important to keep the nasal cavity dry, avoid catching colds, and exercise regularly.
Do vocal cord polyps have to be surgically removed?
Vocal cord polyps must be treated surgically. Vocal cord polyps are caused by improper vocal use for an extended period, overexertion, and yelling, leading to vocal cord lesions. Typically, the disease affects only one vocal cord, causing the patient's voice to be hoarse, with symptoms worsening continuously. During an examination with an electronic laryngoscope, a pale white or pale red smooth granule can be observed on the anterior middle third of the unilateral vocal cord, resulting in incomplete closure of the glottis and consequently a hoarse voice. In terms of treatment, conservative management for vocal cord polyps is ineffective. Patients must undergo a vocal cord polyp removal surgery under suspension laryngoscopy. The surgery requires hospitalization and general anesthesia, followed by the use of antibiotics postoperatively to avoid local infection. Recovery usually allows discharge from the hospital after about a week. However, after recovery, patients still need to speak softly and sparingly, avoid catching colds, and prevent recurrence. (The use of medications should be conducted under the guidance of a doctor.)
Can a deviated septum be seen from the outside?
A deviated nasal septum is not apparent externally; it requires a hospital examination including a nasal endoscopy and a sinus CT scan for a definitive diagnosis. A deviated nasal septum is a common and frequently occurring condition in otolaryngology, with about 90% of people having some degree of deviation. This condition is mainly due to abnormal nasal septum development during the embryonic stage or due to trauma to the nasal septum or compression from nasal tumors occurring later. When the nasal septum deviates to one or both sides, it primarily causes persistent, progressive nasal obstruction on both sides. It also accompanies symptoms like mucous nasal discharge, a sense of swelling or a foreign body in the nasal cavity, facial pain, and headaches. A deviated nasal septum can also lead to complications such as sinusitis and nasal polyps. Diagnosis can be confirmed at a hospital with a nasal endoscopy and sinus CT scan. Treatment involves surgical correction of the deviated nasal septum, which can cure the condition.
What to drink for pharyngitis
Pharyngitis can usually be prevented and treated with honeysuckle tea or monk fruit tea, with good results. Generally, pharyngitis is caused by repeated acute inflammation, long-term intake of spicy foods, gastrointestinal dysfunction, and acidic irritation leading to congestion, edema, and lymph follicle proliferation in the pharyngeal mucosa and submucosal tissues. Symptoms include dry throat, sore throat, itchy throat, foreign body sensation in the throat, obstruction sensation, burning sensation, irritative cough, hoarseness, and difficulty swallowing. Severe cases may also lead to blood in the sputum. Upon examination, noticeable congestion and edema of the pharyngeal mucosa can be found, particularly in the uvula and soft palate. Lymph follicle proliferation can be seen on the posterior pharyngeal wall and pharyngeal recesses, with significant congestion in both vocal cords, though they may not close completely. For treatment, patients should first undergo symptomatic anti-inflammatory treatment. Oral administration of cephalosporin antibiotics has been found to be effective, and it should be combined with nebulized inhalation. Improvement is generally seen within about a week. (The use of medication should be conducted under the guidance of a professional doctor.)
Do the early symptoms of laryngeal cancer include coughing?
Throat cancer refers to malignant tumors that occur in the pharyngeal region. Clinically, it commonly manifests as vocal cord cancer, pyriform sinus cancer, and hypopharyngeal cancer. The causes are linked to long-term smoking, alcohol consumption, gastrointestinal dysfunction, acid reflux, irritations, and improper or excessive use of the voice leading to cellular mutations. In its early stages, patients generally experience persistent worsening hoarseness. Sometimes, patients may also suffer from irritative coughing, a foreign body sensation in the throat, obstruction feeling, and breathing difficulties. Patients need to undergo a detailed examination with an electronic laryngoscope at a hospital, which can reveal cauliflower-like neoplasms in any part of the pharynx. At this point, a local biopsy is necessary. If the biopsy confirms a malignant tumor in the pharyngeal region, local surgical removal is required, followed by relevant radiotherapy or chemotherapy.
