title: Preparation of nasoseptal flap in trans-sphenoidal surgery using 2-μ thulium laser: technical note.
abstract: OBJECTIVE
  The purpose of this study was to assess the feasibility of the use of the 2μ-thulium laser in harvesting nasal septal flaps.
  
  
  BACKGROUND
  Nasal septal flaps are routinely performed in almost every trans-sphenoidal surgery. The preservation of the arterial vasculature is a mainstay of the procedure. However, the margins of the flap should be sufficiently healthy to regenerate faster, reducing the risk of possible complications.
  
  
  METHODS
  Eight patients underwent trans-sphenoidal surgery and removal of pituitary adenomas. Reparation of the defect was performed with the positioning of a rotational vascularized nasal-septal flap. The flaps were harvested with the aid of the 2μ-thulium laser. Every patient was then monitored for 6 months through seriated endoscopic endonasal controls.
  
  
  RESULTS
  There were no complications related to the use of the laser, either intraoperatively, or postoperatively. The operative timing did not significantly differ from that of traditional techniques.
  
  
  CONCLUSIONS
  The use of the 2μ-thulium laser for the harvesting of nasal septal vascularized flaps can be considered safe and feasible. The limited number of treated patients could be considered as the only restriction to the study. A larger study might have uncovered possible instrumentation-related complications, which were not observed in the present study.
