While I appreciate your desire to combine cosmetic and reconstructive, it's also important not to compromise your safety. Multiple procedures are frequently performed, although all PS carefully screen their patient's medical history, beforehand to select the most appropriate candidates. Remember abdominoplasty, breast revisions can be performed in tandem, assuming the patient is evaluated to be fit. In our practice we screen patients with pre-op labs, EKG, CXR and occasionally refer them back to their personal physicians for clearance.
When you introduce another factor, another physician and another plane of dissection, you up the ante substantially. Your surgical results wil depend on the conduct of the myomectomy (removal of the fibroid). Assuming that the Gynecologic portion and the PS procedures can be done within 6 hours, your risk from hypothermia, blood loss, infection should be acceptable. good luck.
