Metzenbaum Scissors: Uses, Features, and Complete Guide

You are in the middle of a surgery. The tissue is delicate. Your standard scissors are too bulky. You need something finer.

That is when you reach for Metzenbaum scissors.

These scissors have a specific job. They cut delicate tissue. They do blunt dissection. They reach into tight spaces where other scissors cannot go.

I have gathered information from medical device registries, veterinary schools, and surgical supply catalogs. Here is everything you need to know about Metzenbaum scissors.

What Are Metzenbaum Scissors?

Metzenbaum scissors are surgical scissors designed for cutting delicate tissue and performing blunt dissection. They have thin, long blades that are typically curved. The blade tips are usually blunt, not sharp.

These scissors are named after Dr. Myron Metzenbaum, an American surgeon who developed them in the 1930s .

The key difference between Metzenbaum scissors and regular scissors is the blade-to-handle ratio. Metzenbaum scissors have long blades relative to their handle length. This design allows for precise cutting in deep or narrow spaces .

Key Features and Design

Let me break down what makes these scissors special.

Blade shape: The blades are thin and delicate. Most Metzenbaum scissors have curved blades, but straight versions also exist .

Blade tips: The tips are typically blunt. This is intentional. Blunt tips allow you to dissect tissue without accidentally cutting something you do not want to cut .

Length range: Metzenbaum scissors come in many sizes. Common lengths include 14 cm, 18 cm, 20 cm, 23 cm, and 26 cm . In inches, you will find 7-inch, 8-inch, and 9-inch models .

Material: Most are made from stainless steel. High-quality versions use martensitic steel, which holds an edge well . Some have tungsten carbide inserts on the cutting edges for longer life .

Baby Metzenbaum: There is a smaller version called Baby Metzenbaum scissors. These are about 145 mm (roughly 5.7 inches) long with a cutting edge of about 32 mm .

What Are Metzenbaum Scissors Used For?

Metzenbaum scissors have two main jobs: cutting tissue and blunt dissection .

Cutting delicate tissue: These scissors cut fine tissue without causing excessive damage. The thin blades make clean cuts through skin, muscle, and fascia .

Blunt dissection: Here is the technique. You place the closed scissors into the tissue. Then you open the blades. The tips spread the tissue apart, separating layers without cutting them . This is useful for exposing structures underneath.

Tight spaces: The long, thin design lets you reach into deep or narrow surgical sites. Other scissors cannot fit where Metzenbaum scissors can go.

Surgical Specialties That Use Metzenbaum Scissors

These scissors appear in multiple surgical fields.

General surgery: For dissecting fascia and cutting soft tissue.

Plastic surgery: For precise cuts on skin and delicate tissue .

Ophthalmology: For fine work around the eye .

Neurosurgery: For cutting and dissecting around the brain and spine .

Dentistry and oral surgery: For periodontal surgery and soft tissue removal around the tooth roots .

Gynecology: For cutting tissue during gynecological procedures .

Veterinary surgery: For fine tissue work in animals. Veterinary students learn Metzenbaum scissors as a standard instrument .

Metzenbaum vs Mayo Scissors: The Difference

This is a common question. Here is the simple answer.

Memory tip from veterinary school: "Long name means long handle" . Metzenbaum has a longer name and longer handles compared to its blade. Mayo has a shorter name and shorter handles.

Proper Use Technique

Using Metzenbaum scissors correctly matters.

For blunt dissection: Close the blades. Insert the tips into the tissue you want to separate. Open the scissors. The tips spread the tissue. Repeat as needed .

For cutting: Place the tissue between the blades. Close smoothly. Do not jerk or force the cut.

What not to cut: Never use Metzenbaum scissors for cutting sutures, drains, gauze, or heavy tissue . That will damage the blades. The thin edges are not made for those materials. Use suture scissors or Mayo scissors for those jobs.

Available Variations

Metzenbaum scissors come in several configurations.

Blade curve: Curved or straight. Curved is more common for reaching around structures. Straight is better for linear cuts.

Tip type: Blunt or sharp. Blunt is standard for dissection.

Serration: Some models have serrated blades. The serrations grip tissue better to prevent slipping .

Finish: Standard stainless steel or black-coated. The black coating reduces glare from surgical lights .

Handle design: Standard finger rings or ergonomic designs. Some have gold screw joints for smoother action .

Laparoscopic version: Monopolar Metzenbaum scissors exist for minimally invasive surgery. These have long shafts (33 cm or 45 cm) with small jaws (12 mm or 18 mm) at the end .

Sizes and Dimensions

Here are the common sizes you will find.

Lengths in metric:

·         14 cm (about 5.5 inches)

·         18 cm (about 7 inches)

·         20 cm (about 8 inches)

·         23 cm (about 9 inches)

·         26 cm (about 10 inches) 

Lengths in imperial:

·         7 inches

·         8 inches

·         9 inches 

Baby Metzenbaum:

·         145 mm total length (about 5.7 inches)

·         32 mm cutting edge (about 1.25 inches) 

Choose the size based on your surgical site. Deeper sites need longer scissors.

GMDN Classification and Regulatory Information

For procurement and regulatory purposes, Metzenbaum scissors fall under specific codes.

GMDN Term Code: 38727
GMDN Term Name: General-purpose surgical scissors, reusable 

Definition: A hand-held manual surgical instrument designed to cut/dissect a variety of tissues during open surgery... comprised of two pivoted shearing blades with handles... typically made of metal... reusable device .

FDA Product Code: LRW (Scissors, General, Surgical) 

EMDN Code: L010403 (Surgical dissection scissors, reusable) 

HS Code for international trade: 901890 

Maintenance and Sterilization

Metzenbaum scissors are reusable instruments. They need proper care.

Cleaning: Clean immediately after use. Remove all blood and tissue from the hinge area. Ultrasonic cleaning works best.

Inspection: Check the blades for nicks, gaps, or misalignment. Check the screw joint for smooth movement. Test the cutting action on a piece of test material (not your finger).

Sterilization: These scissors are autoclavable. Moist heat or steam sterilization is the standard method . Most stainless steel Metzenbaum scissors tolerate repeated autoclave cycles.

When to replace: Replace if the blades have nicks, if the hinge is loose, or if the scissors no longer cut cleanly along the entire blade length.

Common Mistakes to Avoid

I have seen these errors in operating rooms.

Mistake 1: Using Metzenbaum scissors to cut suture.
Fix: Use suture scissors. Metzenbaum blades are too thin and will dull quickly.

Mistake 2: Forcing the scissors through thick tissue.
Fix: If the tissue resists, use a heavier scissor like Mayo scissors. Forcing will bend the thin Metzenbaum blades.

Mistake 3: Using sharp-tipped Metzenbaum for blunt dissection.
Fix: Sharp tips can puncture structures you want to preserve. Use blunt-tip Metzenbaum for dissection.

Mistake 4: Storing them closed.
Fix: Store scissors open. Closed storage keeps the blades pressed together and can damage the cutting edge.

Frequently Asked Questions

Q: Can I use Metzenbaum scissors for cutting gauze or dressings?

A: No. Never use surgical scissors for cutting suture threads, gauze, or dressings . These materials dull the thin blades quickly. Use bandage scissors for dressings and suture scissors for sutures.

Q: What is the difference between Metzenbaum and Lahey scissors?

A: Metzenbaum-Lahey scissors tend to be shorter than standard Metzenbaum scissors . The design is otherwise similar.

Q: Are Metzenbaum scissors disposable or reusable?

A: Most are reusable. They are designed to be cleaned, sterilized, and used again . Single-use disposable versions exist but are less common. The laparoscopic monopolar version mentioned earlier comes in single-use sterile packaging .

Q: What does "tungsten carbide inserts" mean?

A: Some high-quality Metzenbaum scissors have tungsten carbide along the cutting edges . Tungsten carbide is harder than stainless steel. It stays sharp longer. Look for gold-colored handles or screws, which often indicate carbide inserts.

Q: How do I know what size Metzenbaum scissors to buy?

A: Match the size to your surgical site. For surface procedures, 14-18 cm works. For deeper cavities like the abdomen, 20-23 cm is better. For very deep or narrow sites, consider curved blades to see around structures.

Q: Are straight or curved Metzenbaum scissors better?

A: Curved is more common. The curve lets you cut around structures while seeing your tip. Straight is better for linear cuts on flat surfaces. Many surgeons keep both.

Quick Reference Summary

Final Take

Metzenbaum scissors are not for every job. They have one specialty: delicate tissue and blunt dissection.

Use them for that job. They will serve you well.

Use them for cutting suture or gauze. You will ruin the blades.

Buy the right size for your surgical site. Curved is more versatile than straight. Keep them clean. Sterilize them properly. Replace them when the blades get damaged.

Know your instrument. Know its limits. Use it correctly.
