Technical Advantages

Technical Advantages

The Department of Otolaryngology-Head and Neck Surgery specializes in [endoscopic-assisted minimally invasive surgery] for the treatment of nasal septal deviation. The advantages of this procedure are as follows

  • c1_icon_22.svg
    Minimally Invasive Approach
    Correction is performed through a unilateral nasal incision, reducing mucosal injury by 30%-50% compared to traditional techniques and lowering the risk of postoperative nasal adhesion.
  • c1_icon_22.svg
    Precision Correction Technique
    Achieves precise correction of the cartilaginous-bony junction.
  • c1_icon_22.svg
    Mucosal Preservation Strategy
    Utilizes the "submucosal tunnel" technique to preserve mucosal integrity while completing bony structural remodeling, with a postoperative perforation rate of <1%.
  • c1_icon_22.svg
    Biomechanical Reconstruction
    Personalized support structure design based on the deviation type (C-shaped/S-shaped/spur type), achieving a long-term correction success rate exceeding 95%.

Equipment Advantages

Equipment Advantages

  • 1
    4K Nasal Endoscopy System: Equipped with 0° and 30° wide-angle lenses, 20000-pixel resolution clearly visualizes fine structures such as the perpendicular plate of the ethmoid bone.
  • 2
    Low-Temperature Plasma System: Controlled coagulation at 40-70°C, reducing thermal damage by 60% compared to traditional electrocautery, particularly suitable for cases with angiomatous hyperplasia.
  • 3
    Absorbable Materials: Replaces traditional non-absorbable suture fixation methods.
