Best answer is e.
Basically the indication for surgical flaps is inability to remove the structure or tissue without traumatizing the surrounding tissues. If a closed procedure fails , adequate visualization and access are obtained by means of an open procedure. Operations requiring a surgical flap are called open procedures. The operative site should be adequately exposed.
Principles. Healing should take place without complication if basic surgical principles are followed. The incision should be designed so that blood supply of the flap is adequate. If the free end of the flap is wide and the base containing the blood supply is narrow, nutrition to the flap may be inadequate. The flap should contain all the structures overlying bone, including mucosa, submucosa, and periosteum, with special care given to include the periosteum in the flap. The flap should be sufficiently large that adequate vision and space for removal of bone are present without damaging the soft tissues edges. The incision should always be made over bone that will not be removed, so that the sutured incisions are supported by bone. Incision made in tissues that harbor uncontrolled infection may cause rapid spread of infection.
