Name of the Procedure:

Laryngoscopy, direct, operative, with biopsy; with operating microscope or telescope

Summary

A laryngoscopy is a medical procedure where a doctor examines the back of your throat, larynx (voice box), and vocal cords using a special instrument. This form of laryngoscopy involves direct visualization with the assistance of an operating microscope or telescope and may include taking a tissue sample (biopsy).

Purpose

This procedure helps diagnose and treat issues in the throat, larynx, and vocal cords. It is often performed to determine the cause of voice problems, throat pain, or other abnormalities. The goals are to identify abnormalities such as tumors, infections, or structural issues, and to provide samples for biopsy to aid in diagnosis.

Indications

• Chronic hoarseness or voice changes
• Throat pain without an obvious cause
• Difficulty swallowing
• Suspicion of tumors or growths in the throat or vocal cords
• Persistent cough or throat clearing

Preparation

• Patients may need to fast for several hours before the procedure.
• Medication adjustments may be required; consult your doctor.
• Pre-procedure diagnostic tests may include imaging studies or blood tests.
• Discussion of medical history and any allergies with the healthcare provider.

Procedure Description

1. The patient is usually given local or general anesthesia to minimize discomfort.
2. A laryngoscope, which is a thin, tube-like instrument, is inserted through the mouth or nose to reach the throat.
3. An operating microscope or telescope is used to provide a detailed view.
4. If any suspicious areas are identified, a biopsy tool is used to take a tissue sample.
5. The laryngoscope is carefully removed once the examination and biopsy are completed.

Duration

The procedure typically takes 30 to 60 minutes, depending on its complexity.

Setting

Laryngoscopy is usually performed in a hospital's operating room, outpatient clinic, or surgical center.

Personnel

• Otorhinolaryngologist (ENT specialist)
• Nurses
• Anesthesiologist or nurse anesthetist

Risks and Complications

• Sore throat or minor bleeding
• Hoarseness or voice changes
• Infection
• Rare risks include damage to the vocal cords or respiratory issues
• Sedation-related risks, such as allergic reactions or respiratory problems

Benefits

• Accurate diagnosis of throat and vocal cord issues
• Early detection of conditions, such as cancer
• Ability to obtain tissue samples for further analysis

Recovery

• Patients may feel throat soreness or hoarseness after the procedure.
• Resting the voice and following any dietary restrictions are typically recommended.
• Full recovery can take several days to a week.
• Follow-up appointments are necessary to discuss biopsy results and next steps.

Alternatives

• Indirect laryngoscopy: Uses a mirror to view the throat; less invasive but less detailed.
• Imaging studies: Such as CT scans or MRI, which are noninvasive but might not provide a definitive diagnosis.
• Watchful waiting: Monitoring symptoms over time, suitable for less severe cases.

Patient Experience

• Patients might feel some discomfort from the scope.
• Local or general anesthesia helps minimize pain.
• Post-procedure, a sore throat or minor discomfort is common but manageable with pain relief measures.
• Most patients can resume normal activities within a few days, following medical advice on voice rest and other care instructions.
