title: Comparative study of continuous lateral osteotomy and microperforating osteotomy in patients undergoing primary rhinoplasty.
abstract: BACKGROUND
  Lateral osteotomies play an important role in rhinoplasty and can be performed with different techniques.
  
  
  OBJECTIVE
  To compare the results of narrowing of the nasal dorsum and base through 2 types of lateral osteotomy: continuous and microperforating.
  
  
  METHODS
  We selected 74 patients undergoing rhinoplasty: 37 patients underwent lateral continuous osteotomy and the other 37 underwent microperforating osteotomy, all performed by the same surgeon. We analyzed frontal photography from the pre- and post-operative (6 months) periods, evaluating the width of the nasal dorsum and base. This was a retrospective study.
  
  
  CONCLUSIONS
  Using Student's t-test, statistical analysis concluded that there was a statistically significant difference in the post-operative narrowing of the nasal dorsum and base following both osteotomy techniques, and there was no statistically significant difference between the 2 techniques.
