MODIFIED TRIANGLE FLAP
There are many flap designs recommended for the removal of impacted third molars. Western Surgical and Sedation’s STOW will discuss four different flap designs: envelope, triangle, modified triangle, and “S” flap. The most commonly recommended flaps are the envelope and triangle. No flap is perfect for all situations.
The modified triangle flap can be used when maximum access is needed. It can be used in the maxilla or mandible. This flap usually requires two 4.0 sutures to close the releasing incisions and flap (see arrows). The incision distal to the second molar and suture is left open to drain and heals by secondary intention.
