title: Impact of vertical dome division on nasal airflow.
abstract: OBJECTIVE
  Vertical dome division is an effective maneuver in nasal tip surgery. Its applications include reduction of the tip projection, increasing tip rotation, narrowing of the domal arch, and correction of lobule asymmetry. Nevertheless, some surgeons avoid this technique, fearing tip deformity and possibly impaired nasal airflow.
  
  
  RESULTS
  In this study, nasal airflow measurements were made before and after septorhinoplasty with vertical dome division. There was no significant change in the airflow before and after septorhinoplasty with vertical dome division. The airflow was negatively affected in 37.5% and improved postoperatively in 25% of patients.
  
  
  CONCLUSIONS
  Despite objective findings of diminished nasal airflow in some patients following vertical dome division, no subjective correlation was identified. Furthermore, during the postoperative testing, alar retraction on all of these patients failed to normalize airflow results, indicating that alar collapse was not contributing to the airflow impairment in those cases. All of the patients were found clinically asymptomatic after surgery.
