2. HERNIA
• A hernia occurs when an organ or internal
tissue breaks through a hole in the muscles.
Hernia repair surgery or herniorrhaphy
involves returning the displaced tissues to
their proper position. It is one of the most
common surgeries performed in US and
around the globe.
Hernioplasty (mesh repair)
Herniorrhaphy (tissue repair)

4. TYPES OF HERNIAL MESH
• Patches
• Plugs
• Sheets
• Absorbable hernial mesh
• Non absorbable hernial mesh
• Synthetic hernial mesh
• Coated or composite hernial mesh
• Animal derived hernial mesh

5. PATCHES
• Designed to go over or
under the weakened or
damaged tissue

6. PLUGS
• Fit inside the hole in the
tissue

7. SHEETS
• Can be custom cut and
fitted for the patient’s
specific hernia

8. ABSORBABLE HERNIAL MESH
Absorbable mesh degrades and loses strength
over time. It is not used to provide long-term
reinforcement to the repaired hernia. “As the
material degrades, new tissue growth is
intended to provide strength to the repair,”

9. NON ABSORBABLE HERNIAL MESH
• Non-absorbable mesh is a permanent implant.
It remains in the body indefinitely. Non-
absorbable mesh is supposed to provide
lasting reinforcement to the repair site.

10. SYNTHETIC HERNIAL MESH
• Hernia mesh made of synthetic materials
come in woven or non-woven sheets. The
synthetic materials can be absorbable, non-
absorbable or a combination of both. The
most popular types of surgical mesh are made
from polypropylene – a synthetic plastic

11. ANIMAL DERIVED HERNIAL MESH
• Some manufacturers make hernia mesh from
animal tissue. They may use the intestine or
skin of animals. It usually comes from a pig or
cow. Manufacturers process and disinfect it.
This type of mesh is also absorbable.

12. COATED OR COMPOSITE HERNIAL
MESH
• At least one hernia repair technique can leave
mesh in contact with the intestines. This can
cause the intestines to adhere to the mesh,
which can result in severe complications.
Some polypropylene meshes may come
coated with absorbable fatty acids, cellulose
or collagen. Manufacturers claim these
coatings prevent adhesions.
