Hammond 51 Operative Technique Generally speaking, most cases of breast reduction in my practice are still performed under general anes- thesia and include an overnight stay in the hospital. However, cases of mastopexy and smaller reductions of 500 g or less are often performed in an outpatient setting. In preparing for the SPAIR procedure, several details are best managed ahead of time. Inherent in the SPAIR procedure is assessment of the shape of the breast during the procedure, as one of the operative goals is to create an aesthetically appealing breast im- mediately. This must be done with the patient upright Fig. 6.5. The final marking pattern with the skin to be resected at least 80°.
