Laryngeal and voice surgery is a delicate procedure that needs delicacy, precision, and accurate instruments to provide effective results. Delicacy in the vocal cords and tissues surrounding the vocal cords means that the surgical instruments must provide fine control, low trauma, and high-quality visualization. Surgeons use a variety of instruments that are used to diagnose and treat conditions like vocal cord polyps, nodules, tumors, and paralysis.

We will describe the simplest voice surgery instruments and laryngeal surgery instruments utilized in this article, and they are the laryngoscopes, vocal cord micro-scissors, and biopsy forceps. They are all invaluable tools for the exact and efficient diagnosis and treatment of voice disorders.

1. Laryngoscopes: Lighting up the Vocal Cords

The Use of Laryngoscopes in Voice Surgery

Laryngoscopes are vital in visualizing the larynx and vocal cords. They give access to the airway, enabling otolaryngologists and surgeons to conduct diagnostic and therapeutic procedures. There are a number of different types of laryngoscopes, each appropriate to different uses in laryngeal surgery.

Types of Laryngoscopes

a) Direct Laryngoscopes

Direct laryngoscopes enable the surgeon to see the larynx by directly viewing through the instrument or through a camera. They are employed in surgeries such as microlaryngeal surgery and excision of vocal cord lesions.

• Advantages: Offers a clear, magnified image of the vocal cords.
• Common Uses: Removal of polyps, laser surgery, and injections into the vocal cords.

b) Indirect Laryngoscopes

Indirect laryngoscopy employs mirrors or fiber-optic devices to view the larynx without a direct line of vision. These are typically applied to initial diagnoses in outpatient facilities.

• Advantages: Less intrusively inserted than direct laryngoscopy.
• Applications: Diagnostic tests and non-surgical voice evaluation.

c) Rigid vs. Flexible Laryngoscopes

• Rigid Laryngoscopes: Applied to precise surgical procedures where stability and a broad field of vision are necessary.
• Flexible Laryngoscopes: Passed through the nasal passage and are most suitable for in-office procedures and minimally invasive surgery.

Choosing the right laryngoscope

Flexible and rigid laryngoscopy are chosen depending on the operation. More control is gained with a rigid laryngoscope while doing microsurgery, while flexible laryngoscopes are employed for diagnostics as well as minimally invasive surgery.

2. Vocal Cord Micro-Scissors: Precision in Laryngeal Surgery

Significance of Micro-Scissors

Micro-scissors are employed to make precise cuts in delicate laryngeal tissues. They are a critical instrument in microsurgical lesion, nodule, and polyp excisions without sacrificing the functions of intact vocal cords.

High-Quality Micro-Scissor Characteristics

• Sharp, Thin Blades: Provide clean and precise cuts.
• Curved or Straight Blades: Provide versatility in diverse surgical methods.
• Ergonomic Grips: Reduce hand fatigue with long procedures.
• Titanium or Stainless Steel Frame: Offers strength and resistance to corrosion.

Vocal Cord Micro-Scissors Types

a) Straight Micro-Scissors

They are best utilized in creating incisions that are linear and sharp within the vocal cords. They are used for delicate procedures where there is a requirement of creating less tissue damage.

b) Curved Micro-Scissors

Curved micro-scissors allow surgeons to navigate about the contour of the vocal cords. They are particularly used in removing lesions that are difficult to remove using straight scissors.

Applications of Laryngeal Surgery

• Polyp Removal: Removing benign tumors on the quality of the voice.
• Vocal Cord Stripping: Eliminating vocal fold thickening.
• Microflap Surgery: Avoiding destruction of mucosal tissue when eliminating lesions.

Why Micro-Scissors are Critical

The delicacy of laryngeal surgery requires the micro-scissors to deliver maximal control with minimum trauma. Such devices aid in sustaining the use of the voice, a necessary element for professionals dependent upon voice utilization.

3. Biopsy Forceps: Sampling Tissue to Make an Accurate Diagnosis

The Function of Biopsy Forceps in Voice Surgery

Biopsy forceps are employed to collect tissue specimens from the larynx and vocal cords for histopathological examination. A biopsy aids in diagnosing conditions like laryngeal cancer, leukoplakia of the vocal cord, and chronic inflammation.

Types of Biopsy Forceps

a) Cup Biopsy Forceps

Cup biopsy forceps consist of small, rounded jaws, which allow a clean sample of tissue with minimal trauma. They are routinely used in getting biopsies from lesions on the vocal cord.

• Benefits: Offers an exact and controlled tissue removal.
• Usual Applications: Vocal cord tumor, leukoplakia, and chronic inflammation.

b) Alligator Biopsy Forceps

These are provided with serrated jaws to provide enhanced grip and cutting effect. These can be useful when removing somewhat more resistant samples of tissue.

• Advantages: Firm grasp of tissue for a more consistent sample.
• Common Uses: Malignancy diagnosis and chronic laryngeal disease.

c) Flexible Biopsy Forceps

These are meant to be used with flexible laryngoscopes and may be passed through the working channel of the scope for tissue sampling in an office environment.

• Advantages: Least invasive and may be performed without general anesthesia.
• Common Uses: Office biopsies and follow-up tests.

Why Good Quality Biopsy Forceps are Important

• Sharp Blade Tip: Provide a clean tissue sample with less damage.
• Smooth Function: Minimizes trauma to surface tissues.
• Good Design: Made of durable quality stainless steel.

When to Use Biopsy Forceps?

• Suspicious Vocal Cord Tumors: To check whether a tumor is malignant or not.
• Persistent Hoarseness: To investigate chronic laryngitis or inflammation.
• Pre-Treatment Diagnosis: For proper diagnosis prior to therapy.

Conclusion: Selecting the Optimal Laryngeal Surgery and Voice Surgery Instruments

Laryngeal and voice surgery demands specific instruments that ensure precision, control, and minimal tissue damage. Laryngoscopes provide critical visualization, micro-scissors guarantee fine dissection, and biopsy forceps enable precise diagnosis.
