Anatomical terminology |
The nasolabial folds, commonly known as "smile lines" [1] or "laugh lines", [2] [ self-published source ] are facial features. They are the two skin folds that run from each side of the nose to the corners of the mouth. They are defined by facial structures that support the buccal fat pad. [3] They separate the cheeks from the upper lip. The term derives from Latin nasus for "nose" and labium for "lip". Other people suggest the term melolabial fold,[ clarification needed ] [4] or even the lip-cheek fold or groove. [5] It is also known as the nasolabial sulcus.
With ageing the fold may grow in length and depth. [6] Dermal fillings may be used to replace lost fats and collagen in this facial area. [7] Facial exercises give effective results in erasing the appearance of nasolabial folds. [8]
Plastic surgery is a surgical specialty involving the restoration, reconstruction, or alteration of the human body. It can be divided into two main categories: reconstructive surgery and cosmetic surgery. Reconstructive surgery includes craniofacial surgery, hand surgery, microsurgery, and the treatment of burns. While reconstructive surgery aims to reconstruct a part of the body or improve its functioning, cosmetic surgery aims to improve the appearance of it. A comprehensive definition of plastic surgery has never been established, because it has no distinct anatomical object and thus overlaps with practically all other surgical specialties. An essential feature of plastic surgery is that it involves the treatment of conditions that require or may require tissue relocation skills.
The face is the front of an animal's head that features the eyes, nose and mouth, and through which animals express many of their emotions. The face is crucial for human identity, and damage such as scarring or developmental deformities may affect the psyche adversely.
Rhinoplasty, commonly called nose job, medically called nasal reconstruction, is a plastic surgery procedure for altering and reconstructing the nose. There are two types of plastic surgery used – reconstructive surgery that restores the form and functions of the nose and cosmetic surgery that changes the appearance of the nose. Reconstructive surgery seeks to resolve nasal injuries caused by various traumas including blunt, and penetrating trauma and trauma caused by blast injury. Reconstructive surgery can also treat birth defects, breathing problems, and failed primary rhinoplasties. Rhinoplasty may remove a bump, narrow nostril width, change the angle between the nose and the mouth, or address injuries, birth defects, or other problems that affect breathing, such as a deviated nasal septum or a sinus condition. Surgery only on the septum is called a septoplasty.
Facial feminization surgery (FFS) is a set of reconstructive surgical procedures that alter typically male facial features to bring them closer in shape and size to typical female facial features. FFS can include various bony and soft tissue procedures such as brow lift, rhinoplasty, cheek implantation, and lip augmentation.
Oral and maxillofacial surgery is a surgical specialty focusing on reconstructive surgery of the face, facial trauma surgery, the oral cavity (mouth), head and neck, and jaws, as well as facial cosmetic surgery/facial plastic surgery including cleft lip and cleft palate surgery.
A facelift, technically known as a rhytidectomy, is a type of cosmetic surgery procedure intended to give a more youthful facial appearance. There are multiple surgical techniques and exercise routines. Surgery usually involves the removal of excess facial skin, with or without the tightening of underlying tissues, and the redraping of the skin on the patient's face and neck. Exercise routines tone underlying facial muscles without surgery. Surgical facelifts are effectively combined with eyelid surgery (blepharoplasty) and other facial procedures and are typically performed under general anesthesia or deep twilight sleep.
Blepharoplasty is the plastic surgery operation for correcting defects, deformities, and disfigurations of the eyelids; and for aesthetically modifying the eye region of the face. With the excision and the removal, or the repositioning of excess tissues, such as skin and adipocyte fat, and the reinforcement of the corresponding muscle and tendon tissues, the blepharoplasty procedure resolves functional and cosmetic problems of the periorbita, which is the area from the eyebrow to the upper portion of the cheek. The procedure is more common among women, who accounted for approximately 85% of blepharoplasty procedures in 2014 in the US and 88% of such procedures in the UK.
The zygomaticus major muscle is a muscle of the face. It arises from either zygomatic arch (cheekbone); it inserts at the corner of the mouth. It is innervated by branches of the facial nerve.
Facial rejuvenation is a cosmetic treatment, which aims to restore a youthful appearance to the human face. Facial rejuvenation can be achieved through either surgical and/or non-surgical options. Procedures can vary in invasiveness and depth of treatment. Surgical procedures can restore facial symmetry through targeted procedures and facial restructuring and skin alterations. Non-surgical procedures can target specific depths of facial structures and treat localized facial concerns such as wrinkles, skin laxity, hyperpigmentation and scars.
Restylane is the trade name for a range of injectable fillers with a specific formulation of non-animal sourced hyaluronic acid (HA).
Aquamid is a non-absorbable soft volume filler for aesthetic and reconstructive purposes. Aquamid is the trade name for a specific formulation of 97.5% water for injection and 2.5% cross-linked polyacrylamide. It is injected subcutaneously to correct wrinkles and folds or to add volume. Common aesthetic indications are nasolabial folds, lip augmentation, cheek contouring, nose enhancement. Aquamid is also used to correct signs of facial lipoatrophy or fat wasting in HIV+ patients.
Lip reconstruction may be required after trauma or surgical excision. The lips are considered the beginning of the oral cavity and are the most common site of oral cancer. Any reconstruction of the lips must include both functional and cosmetic considerations. The lips are necessary for speech, facial expression, and eating. Because of their prominent location on the face, even small abnormalities can be apparent.
The buccal fat pad is one of several encapsulated fat masses in the cheek. It is a deep fat pad located on either side of the face between the buccinator muscle and several more superficial muscles. The inferior portion of the buccal fat pad is contained within the buccal space. It should not be confused with the malar fat pad, which is directly below the skin of the cheek. It should also not be confused with jowl fat pads. It is implicated in the formation of hollow cheeks and the nasolabial fold, but not in the formation of jowls.
Adenoma sebaceum, also known as facial angiofibroma is a misnamed cutaneous disorder consisting of angiofibromas that begin in childhood and appear clinically as red papules on the face especially on the nasolabial folds, cheek and chin, often misidentified as acne not responding to treatment. Adenoma sebaceum may at times be associated with tuberous sclerosis. Gradually the papules become more prominent with time and persist throughout life. Cosmetic removal by argon or pulse dye laser or scalpel is indicated.
Buccal fat pad extraction or buccal fat removal is a plastic surgery procedure that removes a piece of buccal fat-pad tissue from each side of the face. This reduces the appearance of cheek puffiness, creating a sharper jawline. The amount of fat removed varies based on the desired facial shape. It is a strictly cosmetic surgery.
A lip lift is the most common plastic surgery procedure that modifies the cosmetic appearance of the lips, by reshaping them to increase the prominence of the vermilion border and to enhance the facial area above the lips into a more aesthetically pleasing shape. In corrective praxis, a lip lift procedure is distinguished from lip enhancement, the augmentation of the lips, which can be affected with a non-surgical procedure.
The cheek constitutes the facial periphery and plays a key role in the maintenance of oral competence and mastication. It is also involved in the facial manifestation of human emotion and supports neighboring primary structures.
In human anatomy, the mouth is the first portion of the alimentary canal that receives food and produces saliva. The oral mucosa is the mucous membrane epithelium lining the inside of the mouth.
Injectable filler is a soft tissue filler made of polysaccharides injected into the skin at different depths.
Facial Autologous Muscular Injection is also known as Fat Autograft Muscular Injection, as Autologous Fat Injection, as Micro-lipoinjection, as Fat Transfer and as Facial Autologous Mesenchymal Integration, abbreviated as FAMI. The technique is a non-incisional pan-facial rejuvenation procedure using the patient's own stem cells from fat deposits. FAMI is an Adult stem cell procedure used to address the loss of volume in the face due to aging or surgery repair in restoring facial muscles, bone surfaces and very deep fat pads. The procedure involves removing adult stem cells of fatty tissue from lower body, and refining it to be able to re-inject living adipose stem cells into specific areas of the face without incision. FAMI is an outpatient procedure and an alternative to artificial fillers, blepharoplasty or various face lifts. The procedure does not require general anesthesia and risks of an allergic reaction are minimal due to the use of the patient's own tissue used as the facial injection.
