Facial feminization surgery (FFS) describes a set of procedures designed to alter the facial features of individuals who wish to appear more feminine. The goal of FFS is to create a more harmonious and balanced appearance, helping individuals to feel more comfortable and confident in their own skin. One of the most commonly performed procedures in FFS is jaw angle resection.
Jaw angle resection is a procedure that involves removing a portion of the mandible bone at the back of the jaw. This procedure is performed to reduce the width of the lower face and to create a more delicate and feminine jawline. Many transgender women and gender non-conforming individuals seek this procedure as part of their transition to align their facial features with their gender identity.
The width of the jaw angle is determined by the position of the masseter muscle, which is responsible for chewing. In individuals who have a more prominent jaw angle, the masseter muscle may be larger, resulting in a wider lower face. Jaw angle resection involves removing a small portion of the mandible bone, which reduces the size of the masseter muscle and creates a more feminine jawline.
The procedure is typically performed under general anesthesia and involves making small incisions inside the mouth. The surgeon then uses specialized surgical instruments to remove the desired amount of bone from the jaw angle. The incisions are then closed with dissolvable stitches, and the patient is typically able to return home the same day. If multiple procedures are performed, patients may be asked to stay in the hospital or in a care facility for one night.
Jaw angle resection is considered a safe and effective procedure, with a high rate of patient satisfaction when it is performed by a qualified surgeon. However, as with any surgical procedure, there are risks and potential complications, including infection, bleeding, and nerve damage. The risk of complications can be minimized by choosing a surgeon with the appropriate training and by following all post-operative instructions carefully. Surgeons with craniofacial surgery fellowship training or gender-affirming surgical training are often best equipped to perform this procedure.
While jaw angle resection is a relatively well-known procedure, it is important to note that it is not a one-size-fits-all solution. Each individual’s face is unique, and the amount of bone that needs to be removed may vary depending on their specific anatomy and desired outcome. It is important to work with a surgeon who has experience in FFS and who can help to create a customized treatment plan that is tailored to the patient’s individual needs.
In addition to jaw angle resection, there are a variety of other procedures that may be performed as part of FFS, including rhinoplasty, brow lift, and facial liposuction. These procedures are designed to help create a more feminine appearance by altering the shape and structure of the face.
It is important for individuals considering FFS to thoroughly research their options and choose a qualified and experienced surgeon. Many FFS surgeons offer virtual consultations, which can be a helpful way to get a better understanding of what the procedure involves and whether it is the right choice for you.
In conclusion, jaw angle resection is a commonly performed procedure in facial feminization surgery, with the goal of creating a more feminine and delicate jawline. While there are risks and potential complications associated with the procedure, it is generally considered safe and effective when performed by a qualified and experienced surgeon. Patients should work closely with their surgeon to create a customized treatment plan that is tailored to their individual needs and goals.
