Our Summary

This research study discusses a new way to identify problems with vocal cords. At the moment, the most common way to do this is through a procedure called laryngoscopy, which involves a doctor visually checking the vocal cords for any abnormalities. However, this method can be subjective and depends on the doctor’s expertise.

To make this process more accurate and objective, the researchers developed a computer-based system that uses a type of artificial intelligence called deep convolutional neural network (DCNN) and a technique known as transfer learning. This system was specifically trained using a large number of laryngoscopy images. The researchers then compared the performance of this new system with other similar models.

The results showed that the new system was able to accurately identify different types of vocal cord issues, including normal conditions, polyps, keratinization (hardening of tissues), and carcinoma (cancer). The system was particularly good at distinguishing between urgent and non-urgent conditions. It performed better than doctors in identifying normal, polyp, and carcinoma conditions and did so in a much shorter amount of time.

In conclusion, the new vocal cord diagnosis system, which uses artificial intelligence, was successful in accurately identifying common vocal cord problems. It could potentially improve the overall effectiveness of vocal cord examinations and could be used alongside traditional methods to provide a more accurate diagnosis.

Doctor’s Tip

A doctor might tell a patient undergoing vocal cord surgery to follow post-operative care instructions closely, such as avoiding speaking or whispering for a certain period of time to allow the vocal cords to heal properly. They may also recommend voice therapy to help strengthen the vocal cords and improve voice quality after surgery. It is important to attend all follow-up appointments to monitor progress and address any concerns. Additionally, maintaining good vocal hygiene, such as staying hydrated and avoiding irritants like smoking, can help promote healing and prevent future vocal cord issues.

Suitable For

Patients who are typically recommended for vocal cord surgery include those with:

  1. Vocal cord nodules or polyps: These are noncancerous growths on the vocal cords that can affect voice quality and cause vocal fatigue.

  2. Vocal cord paralysis: This condition occurs when one or both vocal cords cannot move properly, leading to hoarseness, difficulty speaking, and swallowing issues.

  3. Vocal cord cysts: Fluid-filled sacs that can form on the vocal cords and cause voice changes and discomfort.

  4. Vocal cord hemorrhage: This is a medical emergency that occurs when blood vessels in the vocal cords rupture, leading to sudden hoarseness and difficulty speaking.

  5. Vocal cord cancer: Malignant tumors that can develop on the vocal cords and require surgical intervention for treatment.

  6. Vocal cord scarring: Scar tissue on the vocal cords can impact voice quality and may require surgery to improve vocal function.

Overall, vocal cord surgery may be recommended for patients who have persistent voice problems that do not improve with conservative treatments such as voice therapy or medication. It is important for patients to consult with a laryngologist or ENT specialist to determine if vocal cord surgery is the best course of action for their specific condition.

Timeline

Before vocal cord surgery, a patient may experience symptoms such as hoarseness, voice fatigue, difficulty breathing or swallowing, or a sensation of a lump in the throat. They may undergo a laryngoscopy to visually inspect the vocal cords and diagnose any abnormalities. After a diagnosis is made, the patient may be recommended for vocal cord surgery to treat conditions such as vocal cord polyps, nodules, cysts, or cancer.

After vocal cord surgery, the patient will typically experience some discomfort and hoarseness as the vocal cords heal. They may need to rest their voice and follow specific post-operative care instructions to aid in the recovery process. Speech therapy may also be recommended to help improve voice quality and prevent future vocal cord issues. Over time, the patient should experience improvement in their voice quality and overall vocal function. Regular follow-up appointments with a healthcare provider will be necessary to monitor the healing process and ensure optimal outcomes.

What to Ask Your Doctor

Some questions a patient should ask their doctor about vocal cord surgery include:

  1. What specific vocal cord issue do I have that requires surgery?
  2. What are the potential risks and complications associated with vocal cord surgery?
  3. What is the success rate of this type of surgery for my condition?
  4. What is the recovery process like after vocal cord surgery?
  5. Will I need speech therapy or other forms of rehabilitation after the surgery?
  6. How long will it take for me to regain my voice and vocal function after the surgery?
  7. Are there any alternative treatments or procedures available for my vocal cord issue?
  8. How many times has the surgeon performed this type of surgery, and what is their success rate?
  9. What type of anesthesia will be used during the surgery?
  10. How long will the surgery take, and will I need to stay in the hospital overnight?
