Jan 30, 2024 · The superficial musculoaponeurotic system, or SMAS, is often described as an organized fibrous network composed of the platysma muscle, parotid fascia, and fibromuscular layer covering the cheek. This system divides the face's deep and superficial adipose tissue and has region-specific morphology.

Superficial muscular aponeurotic system (or superficial musculoaponeurotic system [1]) (SMAS) is a thin yet tough [2]: 438 unitary tissue plane of the face [3] formed by facial fasciae, subcutis connective tissue, and facial muscles.

In 1976, a superficial musculoaponeurotic system (SMAS) was described in the parotid and cheek regions of the face, dividing superficial and deep adipose tissue [1]. Since then, the definitions and descriptions of the SMAS have been the subject of much debate in the literature.

Jan 30, 2024 · The superficial musculoaponeurotic system, or SMAS, is often described as an organized fibrous network composed of the platysma muscle, parotid fascia, and fibromuscular layer covering the cheek. This system divides the face's deep and superficial adipose tissue and has region-specific morphology.

The Superficial Muscular Aponeurotic System (SMAS) is a key layer of facial muscles that play a critical role in facelift and neck lift procedures. This layer extends from the platysma muscle in the neck and chin area to the galea aponeurotica, which covers the upper part of the scalp.

The superficial musculo-aponeurotic system (SMAS) is the collective name for the superficial fascial structures of the face into which the muscles of facial expression insert. Histologically, this fascia is composed of fibroelastic tissue with the elastic content decreasing with age, leading to sagging of the facial skin over time.

Aug 28, 2023 · The extended SMAS technique is beneficial for patients who require midface rejuvenation along with the lower face and neck. The firm texture of the SMAS allows for less recurrence, less skin tension, and more stability of the facelift.

There are two types of SMAS: Type I, which occurs in the forehead, parotid, zygomatic, and infraorbital areas and consists of fibrous septae, and Type II, which is a dense mesh of collagen, elastin, and muscle fibers found in the lip area. The thickness of …

Feb 1, 2012 · The SMAS is a well-defined portion of the superficial facial fascia that divides the deep and superficial adipose tissue of the face and forms a continuous sheath through the face and neck, and its thickness varies by patient and region of the face.

Oct 29, 2024 · The Superficial Musculoaponeurotic System (SMAS) is a layer of tissue that sits beneath the skin but above the deeper facial muscles. It is a fibrous network that connects the muscles of facial expression to the skin, giving structure and support to the face.
