title: Intraoperative suction-assisted evaluation of the nasal valve in rhinoplasty.
abstract: OBJECTIVE
  To introduce and analyze suction-assisted analysis of nasal valve strength in functional septorhinoplasty. This is a novel method for helping the surgeon analyze the integrity of a patient's airway during surgery.
  
  
  METHODS
  In this prospective study, 20 patients who underwent functional septorhinoplasty were analyzed. Negative pressure using suction tubing was placed at the nasal sill, and measurements of the amount of maximal depression of the nasal valve were performed in the operating room immediately before incision and immediately after closure of the incisions.
  
  
  RESULTS
  All 20 patients had an immediate decrease in the deviation of the weakest point of the valve, with a mean change of 2.14 mm. The change on both sides was statistically significant (paired t test, P < .001). This novel method helped the surgeons decide which grafts provided the most immediate structural benefit.
  
  
  CONCLUSIONS
  Structure-based septorhinoplasty can immediately improve the strength of the nasal valve. Suction-assisted analysis of the nasal valve can be a useful "real-time" tool for determining which maneuvers improve the strength of the nasal valve.
