The bony protrusion you're noticing on the sides of your face could be related to the zygomatic bone (cheekbone), or possibly the temporal bone. It may be more noticeable at certain times due to changes in posture, swelling, or even muscle tension, which can cause temporary shifts in how the bone appears. If it is something structural, it might be due to natural bone development, genetics, or a condition like facial asymmetry. The fact that it sometimes looks normal suggests that it could be related to temporary factors, such as fluid retention or muscle dynamics. To address this, a thorough examination is needed. Depending on the cause, treatments may range from dermal fillers to enhance contour or procedures aimed at reshaping the bone, if it's structural. In some cases, seeing an oral or maxillofacial surgeon may also be recommended. A full evaluation will help identify the cause and guide us in determining the best approach for your specific situation.
