Summary
Forehead flap thickness decreases during tissue expansion, with the most rapid thinning in the first two months. Subcutaneous tissue shows a greater reduction than dermal tissue over the expansion period.
Area of Science:
- Plastic Surgery
- Regenerative Medicine
- Biomedical Engineering
Background:
- Tissue expansion is crucial for reconstructive surgery, providing increased flap size.
- Changes in flap thickness during tissue expansion are not fully understood.
- Forehead flaps are commonly used in reconstructive procedures.
Purpose of the Study:
- To quantify dynamic changes in forehead flap thickness during tissue expansion.
- To assess variations in skin and subcutaneous tissue thickness.
- To determine the rate of thickness change over a 4-month period.
Main Methods:
- Ultrasound measurements of forehead flap thickness (skin and subcutaneous tissue).
- Data collected before and at 1, 2, 3, and 4 months post-expansion.
- Study included 12 patients undergoing forehead expander embedment.
Main Results:
- Forehead flap thickness significantly decreased during expansion.
- The most rapid decrease occurred within the first 2 months.
- Subcutaneous tissue thickness reduced more than dermal tissue thickness.
Conclusions:
- Tissue expansion leads to a notable reduction in forehead flap thickness.
- The rate of thickness reduction slows after the initial 2 months.
- Understanding these dynamic changes is vital for optimizing reconstructive surgery outcomes.

01:02Hypodermis
4.8K
The hypodermis (the subcutaneous layer or superficial fascia) is present directly below the dermis. It connects the skin to the underlying fascia (fibrous tissue) of the bones and muscles. It is not strictly a part of the skin, although the border between the hypodermis and dermis can be difficult to distinguish. The hypodermis consists of well-vascularized, loose, areolar connective tissue and adipose tissue, which functions as a mode of fat storage and provides insulation and cushioning for...

Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.

01:14Muscles for Facial Expressions
2.3K
The craniofacial muscles are a collection of approximately 20 thin skeletal muscles situated beneath the skin of the face and scalp. These muscles, primarily responsible for the vast array of human facial expressions, originate from the bones or fibrous structures of the skull and extend outwards to connect with the skin. While most skeletal muscles in the body are enveloped in thick fascia, facial muscles generally have a more delicate fascial covering, with the buccinator muscle being a...

01:15Reticular Dermis
2.7K
The papillary and reticular dermis are the two layers of the dermis. They are made of connective tissue with fibers of collagen extending from one to the other, making the border between the two somewhat indistinct. The dermal papillae extending into the epidermis belong to the papillary layer, whereas the dense collagen fiber bundles below belong to the reticular layer.
Reticular Layer
Underlying the papillary layer is the much thicker reticular layer, composed of dense, irregular connective...

01:16Accessory Structures of the Skin: Hair and Hair Follicles
2.4K
Hair and hair follicles are integral components of the integumentary system. Hair is a filamentous structure composed mainly of a protein called keratin. It is found on the surface of the skin throughout the body, except for areas such as the palms of the hands and soles of the feet.
Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells. Hair strands originate at the epidermal penetration called the hair follicle. The hair shaft is the part...

01:22Sutures of the Skull
7.1K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
