Square jaw surgery, also known as mandibular angle reduction or jawline contouring, is a specialized cosmetic surgical procedure designed to alter the shape of an overly prominent or square jawline, creating a more oval or streamlined facial appearance. The procedure typically begins with the administration of general anesthesia to ensure the patient remains completely comfortable and pain-free throughout the operation. The surgeon then makes precise intraoral incisions to expose the mandible (jawbone), which helps in avoiding external scarring. Using specialized surgical instruments, the surgeon carefully reduces the size and shape of the mandibular angle by shaving or trimming excess bone and reshaping the jawline. Sometimes, the procedure may also involve the reduction of the masseter muscle, which is responsible for chewing and can contribute to a bulky jaw appearance.

Post-surgery, meticulous suturing of the incisions is performed to facilitate healing and minimize the chances of infection. The patient is then taken to a recovery area where vital signs are monitored as the anesthesia wears off. Recovery from square jaw surgery involves initial swelling, bruising, and discomfort, which can be managed with prescribed medications and cold compresses. Patients are generally advised to adhere to a soft or liquid diet initially to avoid putting strain on the newly shaped jaw and to adhere to meticulous oral hygiene practices to prevent infection. Follow-up appointments are necessary to monitor the healing process and to ensure the desired outcomes are achieved. Over time, as swelling subsides and tissues heal, patients can expect a more balanced and aesthetically pleasing jawline.
