Finally the AITF is based anteriorly and vascularized by the AEA and branches of the anterolateral nasal artery (ALNA) ( ▶ Fig. 11.4).

After harvesting the flap, margins of the perforation are easily elevated and/or rimmed with a 12-blade or a phaco blade. The two mucosal layers surrounding the perforation edges are separated from each other at least 3 to 4 mm in width circumferentially.

Finally the edges are sutured with absorbable suture (i.e., 2–0 Vicryl). Usually anterior, middle, and posterior sutures are placed to achieve complete closure. Sometimes the posterior sutures are difficult to place and they are reserve for the second surgery when the pedicle is detached from the lateral wall.
