Thank you for your question.The simple answer is "yes, it can be safe".However, the components of what you desire vary. If you have a straightforward abdominoplasty, straightforward breast augmentation, and a nose that does not need much refinement, then these procedures may be done at once. If you have a complex abdomen, and a complex breast procedure, combined with a complex nose procedure, it may be best to separate the procedures, as the time under anesthesia may get lengthy at that point.I recommend visiting with a plastic surgeon for an evaluation. Based on your overall health and complexity of the procedures needed, he or she will be able to recommend a single surgery or multiple surgeries to get you the results you ultimately desire.
