title: Keyhole pattern for preoperative marking for reduction mammaplasty.
abstract: BACKGROUND
  There are many techniques used for reduction mammaplasty; however, the most frequently performed procedures result in an inverted T scar. Preoperative marking is an important step for the success of the procedure, especially for surgeons at the initial learning stage. However, there is no consensus regarding the best method. In 1981, Strömbeck designed a pattern for preoperative marking for reduction mammaplasty. This pattern provides stable parameters that promotes an acceptable symmetry marking.
  
  
  OBJECTIVE
  To evaluate the use of the Strömbeck pattern for preoperative marking for reduction mammaplasty.
  
  
  METHODS
  Fifty-seven patients who underwent reduction mammaplasty between April 2006 and April 2007 were prospectively evaluated. Patient ages ranged from 17 to 61 years; the mean body mass index was 22.2 kg/m(2). After defining the standard landmarks of the breast, preoperative markings were made using the Strömbeck pattern. Breast reduction surgery was performed under local anesthesia with sedation. Postoperative results were evaluated according to a numerical visual analogue scale, at the seven-, 15- and 30-day follow-up periods. The Student's t test and the Kruskal-Wallis test were used for statistical analysis (P<0.05).
  
  
  RESULTS
  The mean weight of resected breast tissue was 317.5 g for the right breast and 305.8 g for the left breast (P=0.17). Scores obtained using a visual analogue scale showed a progressive increase in the scores during the postoperative follow-up period (P<0.0001).
  
  
  CONCLUSIONS
  The use of the Strömbeck pattern enabled surgeons to perform reduction mammaplasty with good postoperative results as seen in the follow-up periods.
