Use of Particulate Cortico- Cancellous Anterior Iliac Graft with Periosteum Membrane in Unilateral Alveolar Cleft Grafting Versus Particulate Cortico-cancellous Anterior Iliac Grafting Alone.

skin incision was marked 2-4 cm from the crest to anterior iliac spine height. This is done to avoid pain at the beltline if the incision is made directly over the anterior ilium. As well as avoid injury to the lateral femoral cutaneous nerve. After the anatomical marking are drawn using betadine solution, the site is injected with local anesthesia at the subcutaneous level. The skin incision line is made parallel to the iliac crest and posterior to the anterior iliac spine. Scalpel blade number 10 is used. The incision of the skin and subcutaneous fat was performed. Blunt dissection is carried out at the level of subcutaneous tissues to separate the fascia from fat. Cautery is used to control any hemorrhage. Using a number 15 blade, fascia was incised which covers the iliac spine. A hypo vascular plane was identified. It is located over the anterior iliac spine, as well as between the insertions of tensor fascia laterally and the external and the transverse abdominal muscles medially
