Otolaryngology
About me
With over 10 years of experience in clinical otolaryngology, I have accumulated a certain amount of expertise in diagnosing and treating diseases in this specialty. I have a professional perspective on understanding health issues, believing that prevention is better than cure. Therefore, on online platforms, while addressing the concerns of those seeking advice, I am more willing to provide some popular science knowledge on disease prevention. Those in need are welcome to consult.
Proficient in diseases
Allergic rhinitis, pharyngitis, chronic pharyngitis, sinusitis, nasal polyps, nasopharyngeal carcinoma, laryngeal carcinoma, vocal cord polyps, adenoid hypertrophy, chronic tonsillitis, snoring, tinnitus, thyroid nodules, otitis media, etc.

Early symptoms of throat cancer
The early symptoms of laryngeal cancer vary depending on the type, as laryngeal cancer is categorized into three types. The most common type, accounting for over 80%, is glottic cancer. The early symptom for this type is primarily hoarseness, making it the type of laryngeal cancer where symptoms appear earliest. The other two types are supraglottic and subglottic cancer. These types are less likely to show early symptoms, or the symptoms may not be typical and easily noticeable or taken seriously. The main symptom is a foreign body sensation in the throat, which is often mistaken for pharyngitis or laryngitis and not given due attention. Therefore, when experiencing persistent hoarseness or a noticeable foreign body sensation in the throat, and if throat discomfort persists, it is advised to visit the Ear, Nose, and Throat (ENT) department of a hospital promptly for an examination with an electronic laryngoscope. This can help in the early detection, exclusion, and diagnosis of the condition.
Can you eat after a total laryngectomy for throat cancer?
After the total laryngectomy for throat cancer, a period of recovery is necessary, during which time liquid food is administered via a nasogastric tube. Once recovery is complete, it is possible to eat orally. Because the entire larynx is removed during a total laryngectomy, the functions of voice and breathing are lost, and breathing is instead facilitated through a tracheostomy in the neck. Eating is completely unaffected. After recovery from the total laryngectomy, food is ingested orally, passes through the pharynx, and goes directly into the esophagus. Thus, it is possible to eat orally after a total laryngectomy for throat cancer.
Vocal cord polyp general anesthesia surgery process
Vocal cord polyp surgery under general anesthesia currently involves the use of a combined inhalation and general anesthesia approach, employing a supporting laryngoscope for the excision of the vocal cord polyp. Before the surgery begins, general anesthesia is administered. After the patient is under general anesthesia, the doctor uses a supporting laryngoscope to fully expose the vocal cord polyp. Next, through a fibroscope, in conjunction with fiberoptic instruments or a carbon dioxide laser, the vocal cord polyp is completely excised. The source of the vocal cord injury is repaired to make the vocal cord surface smooth, and then the surgery is concluded. After the surgery, the anesthetist waits for the patient to wake up from the general anesthesia before they can be taken back to their room. The overall duration of the procedure, from anesthesia to surgery to awakening, is typically about an hour or so. Of course, treatment needs to be tailored to the specific patient. In some patients, the vocal cord polyps may not be easily exposed under the supporting laryngoscope, which might extend the duration slightly, whereas in others, where the exposure is straightforward, the procedure may be relatively shorter.
Do you need to be hospitalized for nasal polyp surgery?
The current nasal polyp surgery requires a general anesthesia and endoscopic nasal polypectomy. Since the surgery is performed under general anesthesia, more thorough preparations are made for hospitalized patients. The surgery demands high standards, thus preoperative blood tests and related cardiopulmonary function tests are necessary, requiring hospitalization. Additionally, after the surgery, nasal packing is needed to monitor the patient's recovery and to clean the nasal cavities and sinuses. Therefore, hospitalization is needed for this type of treatment, which generally lasts from 5 to 7 days from admission to discharge.
How is a deviated nasal septum caused?
In this situation, we need to consider various factors. The most common primary cause is a congenital uneven development of the nasal septum, which leads to what we call congenital deviation of the nasal septum. Another cause is abnormal development or injury acquired later in life. For example, one common issue is children who snore loudly for extended periods during sleep and breathe through their mouths; they can develop enlarged adenoids, which might cause the upper jaw to protrude. This, in turn, can lead to abnormal development and deviation of the nasal septum. Additionally, injuries often occur when children are playing or accidentally during physical activities, leading to a direct impact on the nasal septum. Without immediate and proper attention, this can cause a deviation in the septum as development continues.
Can you swim with otitis media?
Patients with otitis media should not swim, whether it is acute or chronic otitis media. This is because water can enter the ear during swimming. Once dirty water enters the ear, especially in cases of chronic otitis media, it can lead to an acute episode of chronic otitis media. Many patients with chronic otitis media have a perforated eardrum. Without the protection of the eardrum, dirty water can directly enter the middle ear, causing an acute episode of otitis media. This can result in suppuration, ear discharge, and further deep infections, such as infections reaching the deep bone tissue of the mastoid, which requires a long time to treat and might even necessitate surgical intervention. If it is the acute phase of otitis media, the entry of water can irritate the eardrum or cause the pus in the middle ear to worsen, further hindering recovery and exacerbating the condition.
