Throat cyst?


Hello, Director Zheng! Previously, I discovered swelling in my neck lymph nodes, so I have been continuously monitored at a major hospital in central Taiwan.
I underwent nasal endoscopy, head and neck ultrasound, and fine needle aspiration, and the doctors indicated that no significant issues were found.
They recommended follow-up every 3 to 6 months.
It has been a year and a half, and the lymph node has remained unchanged in size.
Recently, I have been feeling a persistent sensation of something stuck in my throat and frequent coughing, so two different doctors arranged for nasal endoscopy examinations.
The first doctor noted signs of vocal cord atrophy and incomplete closure.
Last week, during a follow-up with another doctor, I was informed that there is a cyst in my throat.
The doctor mentioned that it appears small and smooth, which is not indicative of malignancy, so they suggested monitoring it and returning for a follow-up in three months.
I would like to ask Director Zheng: (1) Is a cyst the same as a fluid-filled sac? (2) Can nasal endoscopy distinguish between benign and malignant cysts? (3) Is surgery always necessary for a cyst? (4) What recommendations do you have regarding the cyst in my throat? Thank you!

Dr. Zheng Jueyi reply Otolaryngology


Hello, (1) A cyst may be a fluid-filled sac; it is recommended to confirm this with a clinical physician.
(2) Nasal endoscopy can help assess whether a condition is benign or malignant based on clinical presentation.
If there are concerns, a biopsy is generally recommended.
(3) Currently, it is advised to follow the clinical physician's recommendation for regular outpatient follow-ups, and any issues can be discussed further with the clinical physician.
Wishing you safety and health.
Sincerely, Dr.
Jue-Yi Cheng, Director of the Department of Otolaryngology, Taoyuan General Hospital, Ministry of Health and Welfare.

Hello! Thank you for your inquiry regarding throat cysts, specifically the water cyst you mentioned. Let’s address your questions one by one and provide some additional context about throat cysts, their causes, diagnosis, and treatment options.

1. Is a water cyst the same as a cyst?
Yes, a water cyst can be considered a type of cyst. Cysts are sac-like structures that can be filled with fluid, air, or other substances. In the throat, these cysts can form in various locations, including the vocal cords, and may be referred to as mucous retention cysts or other specific types depending on their characteristics. The term "water cyst" typically indicates that the cyst is filled with a clear fluid, which is often a benign finding.

2. Can a nasal endoscopy differentiate between benign and malignant cysts?
Nasal endoscopy is a valuable diagnostic tool that allows physicians to visualize the structures within the nasal passages and throat. While it can provide significant information about the appearance and location of a cyst, it may not definitively determine whether a cyst is benign or malignant. Additional diagnostic methods, such as imaging studies (like ultrasound or CT scans) and possibly a biopsy, may be necessary to make a conclusive diagnosis. The characteristics of the cyst, such as its size, shape, and growth pattern, can provide clues, but a definitive diagnosis often requires further investigation.

3. Is surgery always necessary for a water cyst?
Not necessarily. The decision to surgically remove a cyst depends on several factors, including its size, location, symptoms, and whether it is causing any functional issues (such as difficulty swallowing or breathing). If the cyst is small, asymptomatic, and appears benign, as your doctor suggested, a watchful waiting approach may be appropriate. Regular follow-ups can help monitor any changes in the cyst's size or characteristics. However, if the cyst grows or begins to cause symptoms, surgical intervention may be considered.

4. What recommendations do you have for a throat water cyst?
Given that your cyst is currently small and appears benign, it is reasonable to follow your doctor's advice for monitoring. Here are some general recommendations:
- Regular Follow-ups: Continue with the scheduled follow-ups to monitor the cyst. If you notice any changes in symptoms, such as increased discomfort, difficulty swallowing, or changes in your voice, inform your healthcare provider promptly.

- Voice Care: If you experience voice changes or hoarseness, consider voice therapy or working with a speech-language pathologist to ensure you are using your voice correctly and to prevent strain.

- Healthy Lifestyle: Maintain a healthy lifestyle, including staying hydrated, avoiding irritants (like smoking or excessive alcohol), and managing allergies, which can help reduce throat irritation.

- Seek a Second Opinion: If you have concerns about the diagnosis or treatment plan, don’t hesitate to seek a second opinion from another ENT specialist.

In conclusion, while the presence of a water cyst in the throat can be concerning, many such cysts are benign and do not require immediate intervention. Regular monitoring and communication with your healthcare provider are key to managing your condition effectively. If you have any further questions or concerns, please feel free to reach out. Thank you!
