What is vocal cord surgery?

Vocal cord surgery is a precise medical procedure, often performed using a laryngoscope (endoscope), aimed at treating voice disorders caused by problems in the vocal cords. These conditions may include chronic hoarseness, removal of polyps or cysts, treatment of tumors, or management of vocal cord paralysis through injections or appropriate surgical intervention.

The procedure is usually performed under general anesthesia and takes about one hour. It is considered a highly successful treatment, with success rates ranging from 80% to 95% in improving voice quality or restoring normal vocal function.

---

Is vocal cord surgery painful?

The procedure is performed under anesthesia, either general or local depending on the patient’s condition, so there is no pain during the surgery.

After the operation, the patient may experience mild to moderate throat discomfort, which is usually well controlled with pain medications prescribed by the doctor.

---

Does the voice return to normal after surgery?

In many cases, patients notice a significant improvement in voice quality after surgery.

However, a 100% return to normal voice is not always guaranteed, as it depends on:

• The underlying cause of the condition
• The extent of damage to the vocal cords
• The duration of the problem before treatment

---

How long does vocal cord surgery take?

The procedure usually takes between 20 minutes and one hour, depending on the type of intervention, such as endoscopic surgery, laser treatment, or therapeutic injection.

---

Can the patient speak immediately after surgery?

In most cases, patients are advised to:

• Completely avoid speaking for the first few days after surgery
• Even avoid whispering in some cases

Speech is gradually resumed according to the doctor’s instructions to ensure proper healing of the vocal cords.

---

How long is the recovery period?

Recovery happens in stages:

• Initial improvement: within a few days to two weeks
• Full recovery: may take 3 weeks to several months, depending on the case and type of surgery

---

Are there risks to the voice after surgery?

Some temporary effects may occur, such as:

• Temporary hoarseness
• Mild changes in voice tone

These effects usually improve gradually during the healing period.

---

Can vocal cord surgery fail?

Failure is rare, but in some cases the expected improvement may not be fully achieved. This may include:

• Recurrence of polyps or lesions
• Incomplete improvement of the voice

This is often linked to ongoing causes such as smoking or continued voice strain.

---

Does smoking affect the success of the surgery?

Yes, smoking has a significant negative impact on surgical outcomes. It:

• Reduces the success rate
• Slows down healing of the vocal cords
• Increases the risk of recurrence

Patients are strongly advised to stop smoking before and after surgery.

---

Are speech therapy sessions necessary after surgery?

In most cases, yes. Speech therapy is important because it:

• Helps retrain proper voice use
• Reduces strain on the vocal cords
• Prevents vocal overuse and injury

---

Is vocal cord surgery performed using an endoscope?

Yes, in most cases the procedure is performed using an endoscope through the mouth without the need for open surgery.

In rare cases, an external surgical approach may be required depending on the condition.

---

Can the patient eat normally after surgery?

Initially, patients are advised to:

• Eat soft foods and warm liquids
• Gradually return to a normal diet based on the doctor’s instructions and healing progress 

13. Can the problem return after vocal cord surgery?
Yes, in some cases the problem may return, especially if the underlying cause is not treated. Common factors include:

• Smoking
• Excessive voice use or shouting
• Gastroesophageal reflux (acid reflux)

---

14. When should you see a doctor immediately after vocal cord surgery?
You should seek urgent medical attention if any of the following symptoms appear:

• Difficulty breathing or a feeling of choking
• Bleeding from the mouth or throat
• Severe pain that does not improve with painkillers
• Sudden worsening of the voice instead of improvement

---

Indications and Reasons for Vocal Cord Surgery

Vocal cord surgery is performed in specific cases when medication or speech therapy is not effective, or when the condition significantly affects voice or breathing.

---

First: Indications for surgery

Doctors may recommend surgery in the following cases:

1. Chronic hoarseness

When voice changes or hoarseness persist for weeks or months due to:

• Vocal polyps
• Vocal cord nodules
• Vocal cysts

2. Benign or malignant tumors

• Benign lesions affecting vocal cord movement
• Suspected or confirmed malignant tumors in the larynx

3. Vocal cord paralysis

When one or both vocal cords stop moving normally, leading to:

• Weak voice
• Difficulty breathing or swallowing

4. Breathing difficulties

In severe cases such as:

• Narrowing of the airway due to swollen vocal cords
• Partial obstruction of the larynx

5. Failure of conservative treatment

When non-surgical treatments fail, such as:

• No improvement with medications
• Failure of speech therapy sessions

6. Injury or scarring of the larynx

Due to:

• Accidents or trauma
• Previous surgeries
• Chronic inflammation leading to tissue fibrosis

---

Second: Causes of vocal cord problems

Before reaching surgery, several common factors may lead to vocal cord disorders, including:

• Improper or excessive voice use (shouting, prolonged speaking—common in teachers and singers)
• Smoking
• Acid reflux (GERD)
• Recurrent laryngeal infections
• Chronic allergies

---

Preoperative Preparation for Vocal Cord Surgery

Before vocal cord surgery, patients go through an important preparation phase to ensure safety, improve success rates, and reduce complications.

---

First: Pre-surgery tests and examinations

1. General laboratory tests

• Complete blood count (CBC)
• Blood clotting tests
• Liver and kidney function tests
• Blood sugar level

2. Laryngeal evaluation

• Direct or flexible laryngoscopy
• Precise identification of the vocal cord problem
• Assessment of lesion extent

3. Imaging tests (if needed)

• CT scan of the neck or chest
• MRI in suspected tumor cases

---

Second: Medical evaluation

• Consultation with an ENT specialist
• Pre-anesthesia assessment
• Ensuring the patient can safely tolerate anesthesia
• Checking for heart or lung diseases

---

Third: Important preoperative instructions

Smoking cessation

Patients must stop smoking before surgery because it:

• Delays healing
• Increases inflammation
• Reduces surgical success

Medications

Patients must inform the doctor about all medications, especially:

• Blood thinners (e.g., aspirin may be temporarily stopped)
• Blood pressure and diabetes medications (adjusted if needed)

Fasting before surgery

• No food or drink for 6–8 hours before surgery
• To avoid anesthesia-related complications

---

Fourth: Voice and general preparation

Doctors may recommend:

• Reducing voice use as much as possible
• Treating any active throat infections
• Managing acid reflux if present

---

Fifth: Explaining the procedure and consent

The doctor will:

• Explain the reason for surgery in detail
• Clarify the expected surgical approach
• Discuss possible effects on the voice

Then the patient signs an informed consent form after understanding all details.

---

Sixth: Psychological preparation

Vocal cord surgery can be sensitive, especially in cases involving tumors or severe vocal loss. Patients should be aware that:

• The voice may change significantly or be temporarily lost
• Alternative communication methods may be needed
• Voice rehabilitation may be required after surgery

Methods of Performing All Types of Vocal Cord Surgery

Vocal cord surgery is not a single fixed procedure. Instead, it includes several precise surgical techniques that vary depending on the underlying problem, such as polyps, vocal cord paralysis, chronic hoarseness, or tumors. Below is a simplified explanation of the main procedures and how each one is performed:

---

First: Removal of Polyps, Nodules, and Cysts

Surgical method:

• The procedure is performed under general anesthesia
• A microscopic laryngoscope is inserted through the mouth
• The vocal cords are magnified for precise visualization
• Abnormal tissues such as:
  • Polyps
  • Nodules
  • Cysts
    are carefully removed

Tools used:

• Very fine surgical instruments
• Laser in some cases

Duration:

• Approximately 20 to 60 minutes

---

Second: Laser Surgery

Surgical method:

• A laryngoscope is inserted through the mouth
• A precise laser beam targets the affected tissue
• Abnormal tissues are removed or vaporized

Uses:

• Small tumors
• Vocal cord polyps
• Superficial scar tissue

Advantages:

• Less bleeding
• Higher precision in preserving healthy tissue

---

Third: Vocal Cord Injection (Injection Laryngoplasty)

Surgical method:

• Performed under local or general anesthesia
• A very fine needle is inserted into the vocal cord
• Materials such as collagen or fillers are injected

Purpose:

• Improve vocal cord closure
• Treat hoarseness or weak voice
• Manage partial vocal cord paralysis

Duration:

• 10 to 30 minutes

---

Fourth: Medialization Thyroplasty

Surgical method:

• A small incision is made in the neck
• A small implant is inserted into the laryngeal cartilage
• The vocal cord is pushed toward the midline

Uses:

• Permanent vocal cord paralysis

Note:

• In some cases, the patient may speak during surgery to adjust voice quality

---

Fifth: Vocal Cord Reinnervation

Surgical method:

• Healthy nerves are reconnected to laryngeal muscles
• Or a nerve is transplanted from another part of the body

Purpose:

• Restore natural vocal cord movement

Results:

• Gradual improvement over several months

---

Sixth: Airway Widening Procedures

Surgical method:

• Removal of tissue causing airway narrowing
• Or widening of the laryngeal opening
• Laser or fine surgical tools may be used

Uses:

• Severe breathing difficulties
• Partial airway obstruction

---

Diet After Vocal Cord Surgery

After vocal cord surgery, diet plays a key role in recovery, as it helps the tissues heal properly and reduces irritation to the larynx.

---

First: Diet in the early recovery phase

1. Soft and easy-to-swallow foods (most important stage)

For the first 3 to 7 days (depending on the doctor’s advice), food should be:

• Very soft
• Easy to swallow
• Does not require heavy chewing

Examples:

• Warm soup (not too hot)
• Yogurt
• Mashed potatoes
• Soft rice
• Soft-boiled eggs
• Jelly or pudding

---

2. Fluids (essential for recovery)

It is important to drink plenty of fluids such as:

• Water
• Non-acidic natural juices (apple, pear)
• Warm soothing drinks

Important notes:

• Avoid carbonated drinks
• Avoid acidic juices like orange or lemon in the early stage

---

Second: Foods to avoid

❌ Hard foods:

• Tough meats
• Nuts
• Dry or toasted bread

❌ Irritating foods:

• Spicy foods (hot peppers, strong spices)
• Acidic foods (tomatoes, citrus fruits)
• Crunchy or sharp foods

❌ Drinks to avoid:

• Excess caffeine (coffee, tea)
• Alcohol
• Carbonated beverages

---

Third: Proper eating habits

• Eat slowly
• Chew food well when returning to normal diet
• Drink water during meals
• Eat small frequent meals instead of large portions

---

Fourth: After the first week

• Gradual return to normal diet
• Continue avoiding:
  • Very spicy foods
  • Heavy fried foods
  • Foods that trigger acid reflux

---

Fifth: If acid reflux is present

Patients with GERD should follow a special diet:

• Eat small frequent meals
• Avoid eating before bedtime
• Reduce fatty and spicy foods

Because acid reflux can delay healing and affect surgical outcomes.
