“…During aesthetics procedures, i.e., facelift, the superficial musculoaponeurotic system (SMAS) layer is surgically dissected, and the facial muscles are manipulated through various flap dissections and surgical approaches. Special attention is required when performing dissections at the level of the parotid-masseteric region to avoid injuring the branches of the facial nerve, masseteric ligament, and muscle fibers of the risorius [10][11].…”

The risorius is a very thin muscle and is one of the superficial muscles of facial expression, which is reported as being inconstant, as it is absent in most people, and is a unique muscle; once it has no bony origin. The study aimed to report a different pattern of arrangement of the risorius muscle fibers. During a routine Anatomy class, a different pattern of arrangement of the risorius muscles fibers was found from the observation of an adult (around 40 years old) male cadaver hemiface (right side). After dissections, it was possible to note that the arrangement of the risorius muscle fibers on the surface of the masseteric fascia was formed in different arrangements formed in two bands. In conclusion, the risorius muscle fibers are not always easily distinguishable, and detailed knowledge of their different morphological arrangement is essential when planning and performing facial procedures.

“…The presented sensory impairment can most probably be related to the loss of function of neural cells within the trigeminal ganglion which transmit the sensory information from the ipsi‐lateral skin surface received from the supraorbital, supratrochlear, infraorbital, zygomatico‐facial, buccal, auriculotemporal, and mental nerves. The supraorbital, supratrochlear, and auriculotemporal nerves provide also sensation to the scalp and the upper aspect of the auricle 9 …”

“…The supraorbital, supratrochlear, and auriculotemporal nerves provide also sensation to the scalp and the upper aspect of the auricle. 9 The loss of sensation from the nasal and oral mucosa can most probably be related to the inability of information transmission obtained from the nasopalatine, greater and lesser palatine, and lingual nerves. The latter nerves are also responsible for the impaired perception of a food bolus located inside in the left-sided oral cavity and lateral aspect of the tongue.…”

“…The marginal mandibular, buccal and zygomatic branches of the facial nerve travel within fi brous connective tissue sheets that connect the PM fascia to the SMAS, which encloses surgical access spaces that are used in face-lifting procedures. These spaces are the lower, middle and upper premasseter spaces (Table 2 ) [ 7,27,56,57 ] . The transverse facial artery runs in the superior premasseter space and gives off a branch that runs within the zygomatic ligament (McGregor's patch) to provide axial blood supply to the overlying SMAS.…”

Summary Objective There has been a significant shift in the understanding of facial anatomy during the last decade. Newer minimally invasive therapeutic options for facial rejuvenation procedures are increasing the need for a better knowledge of anatomy. Material and Methods The current literature is summarized, analyzed and presented along with the experience of the author for this narrative review, which summarizes the current understanding of the superficial and deep facial fat compartments and their relevance for minimally invasive facial procedures. A schematic facial model was created in order to facilitate a better understanding of the complexity of facial anatomy. Results The face is arranged in five layers as follows: layer 1: skin; layer 2: subcutaneous fat including the retinacula cutis (composed of fibrous connective tissue); layer 3: superficial musculo‐aponeurotic system (SMAS); layer 4: deep fat; and layer 5: periosteum or deep fascia. This arrangement varies between facial regions, especially when the line of ligaments is incorporated into the model. The facial fat compartments are located in layers 2 and 4; each layer has unique characteristics and spatial relationships with the surrounding tissues. Conclusions The concept of the layered arrangement is a new way to understand the spatial relationship and functional interplay of the soft tissues of the face. Understanding the layers, the precise location of the superficial and deep facial fat compartments and their boundaries is crucial for the conduct of safe and effective minimally invasive facial procedures.
