Patients may seek aesthetic surgery for many reasons. They may present with expectations for both the surgical outcome and the impact that their changed appearance will have on their lives. The desire for an aesthetic procedure is usually driven by increased levels of self-consciousness. The surgeon must be able to identify those patients where the psychological outcome of aesthetic surgery is likely to be poor, and where the self-consciousness of the patient is abnormal. A mnemonic (DESIRABLE OP) is presented with the aim of providing surgeons with a screening tool that can lead them through the psychological assessment of any patient seeking an aesthetic procedure and enable them to determine whether its undertaking constitutes a desirable operation?
