Subfascial dissection is a medical term used to describe a surgical or anatomical procedure in which dissection or separation occurs beneath a fascial layer. Fascia is a connective tissue that surrounds muscles, nerves, blood vessels, and various other structures in the body. Subfascial dissection typically involves carefully separating tissues or structures while staying beneath the fascial layer to access the area of interest.

This approach is commonly used in various surgical procedures and medical interventions, including:

Plastic and Reconstructive Surgery: Subfascial dissection may be used to access and modify muscle and tissue structures beneath the fascial layer to achieve specific cosmetic or reconstructive goals.

Endoscopic Surgery: In minimally invasive endoscopic procedures, surgeons often perform subfascial dissection to access and work on structures within the body without making large incisions.

Nerve and Vascular Surgery: When dealing with nerves and blood vessels, such as during vascular surgeries, subfascial dissection may be performed to access and repair or modify these structures.

Orthopedic Surgery: In some orthopedic procedures, surgeons may use subfascial dissection to access and repair damaged muscles, tendons, or other tissues.

Breast Surgery: Subfascial dissection may be employed in breast surgeries, such as breast augmentation, to create a pocket beneath the pectoral fascia for the placement of implants.

The term “subfascial” simply indicates that the dissection is occurring beneath the fascial layer. The fascial layer serves as a protective barrier for underlying structures and is carefully preserved during this type of dissection to minimize damage and ensure the success of the surgical procedure. The specific techniques and approaches used in subfascial dissection will vary depending on the medical procedure and the area of the body being addressed.
