Delayed Mandibular Hematoma Following Selective Androgen Receptor Modulator (SARM) Usage.

Selective androgen receptor modulators (SARMs) have been used for various conditions since the late 1990s. Functioning similarly to testosterone, they are used to improve sexual function, skeletal muscle mass, and bone mass, and exhibit other favorable physiological effects. While SARMs are associated with side effects varying from edema to polycythemia, the biggest concern is their lack of regulation, as they are not FDA approved. Recent findings suggest the use of SARMs for reducing breast cancer tumor growth and is being explored for its effects in AR+/HER2-/ER+ advanced breast cancer development. Given the potential for SARMs in breast cancer treatment, plastic surgeons must begin to consider navigating the use of SARMs in practice and preoperative consultations regarding SARM usage. In addition, SARMs' anticoagulative properties must be further examined. This case presents a delayed hematoma following treatment for maxillary hypoplasia. Our findings indicate that the patients' usage of SARMs is responsible for the postoperative complications.
