Our Summary

This research investigates whether using ultrasound to guide a specific type of anesthesia, known as a cervical plexus block (CPB), could improve the effectiveness of certain throat surgeries, specifically type I thyroid cartilage laryngoplasty (TCL) and vocal cord medialization (VCM).

Patients undergoing these throat surgeries were given this anesthesia, with the aid of an ultrasound to guide it. A medication called dexmedetomidine was also given intravenously (through the vein) to help with painless sedation, while also keeping the patient awake enough to use their voice during surgery.

Health parameters like blood pressure, heart rate, and oxygen levels were monitored, as well as any potential complications from the anesthesia. The researchers found that all patients underwent the procedure safely without the need for additional anesthesia or complications. Only 2 of 15 patients required additional pain medication.

The heart rate and blood pressure remained stable during surgery, except for a decrease in systolic blood pressure (the pressure in your blood vessels when your heart beats).

In summary, the use of ultrasound-guided CPB with dexmedetomidine is a safe method of anesthesia for patients undergoing these specific types of throat surgeries.

Doctor’s Tip

One helpful tip a doctor might give a patient about vocal cord surgery is to follow all pre-operative instructions provided by your healthcare team. This may include fasting before surgery, avoiding certain medications, and staying hydrated. By following these instructions, you can help ensure a smooth and successful surgery outcome.

Suitable For

Patients who are typically recommended vocal cord surgery include those with vocal cord paralysis, vocal cord nodules or polyps, vocal cord cysts, laryngeal cancer, or other conditions that affect the function of the vocal cords. These surgeries are usually recommended when conservative treatments such as voice therapy or medication have not been effective in improving voice quality or function.

It is important for patients to undergo a thorough evaluation by an otolaryngologist (ENT doctor) to determine if vocal cord surgery is the appropriate treatment option for their condition. The decision to undergo surgery should be made in collaboration with the medical team, taking into consideration the potential risks and benefits of the procedure.

Overall, vocal cord surgery can be a beneficial treatment option for patients with certain voice disorders or conditions affecting the vocal cords, helping to improve voice quality, function, and overall quality of life.

Timeline

Before vocal cord surgery:

  1. Patient consults with an otolaryngologist (ENT) to discuss symptoms and determine if surgery is necessary.
  2. Patient undergoes a thorough evaluation, including a physical exam and possibly imaging tests such as a laryngoscopy.
  3. Surgery is scheduled and patient receives instructions on preoperative preparations, such as fasting before surgery.

During vocal cord surgery:

  1. Patient is given anesthesia, which may include a cervical plexus block (CPB) guided by ultrasound.
  2. Dexmedetomidine is administered intravenously to provide painless sedation while allowing the patient to remain awake and use their voice during surgery.
  3. Surgery is performed to address issues such as vocal cord paralysis or other vocal cord disorders.

After vocal cord surgery:

  1. Patient is monitored for any complications from the anesthesia and surgery, such as changes in blood pressure or heart rate.
  2. Pain medication may be provided as needed for postoperative pain.
  3. Patient receives instructions for postoperative care, including voice rest and follow-up appointments with the otolaryngologist.

Overall, the use of ultrasound-guided CPB with dexmedetomidine has been shown to be a safe and effective method of anesthesia for patients undergoing vocal cord surgery.

What to Ask Your Doctor

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

  1. What specific type of vocal cord surgery will I be undergoing?
  2. What are the potential risks and complications associated with this surgery?
  3. How will the anesthesia be administered during the surgery?
  4. Will I be awake during the surgery, and will I be able to use my voice?
  5. What monitoring will be in place to ensure my safety during the procedure?
  6. How long is the recovery period expected to be, and what can I expect in terms of pain management?
  7. Are there any specific post-operative instructions or restrictions I should follow?
  8. What is the success rate of this type of surgery, and what are the potential outcomes?
  9. How experienced are you in performing this type of surgery?
  10. Are there any alternative treatment options available for my condition?
