Figure-of-Eight Vertical Mattress Suture Technique for Anterior Flap Suspension to Overlying Tissues in External Dacryocystorhinostomy

Such a modified suture technique reveals a rapid and simultaneous one-step closure of two different layers that speeds up surgical procedure; simplifies closure process as the knots are tied completely outside the wound, avoiding the disadvantages of suture tying in a small and deep area; eliminates the dead space between anterior flaps and overlying wound tissues; keeps anterior mucosal flap complex away from posterior flaps that prevents collapse back onto the anastomosis and decreases the possibility of mucosal adhesions and, therefore, fibrotic band formation with underlying tissues that may also be useful in cases with small sacs or osseous openings and in revision cases where scarring is a large concern.
