Sagittal split of harvested coronoid process: a technique to augment harvested bone

Use of the coronoid process as a donor site for bone grafting was first described by Youmans and Russell1 to treat non-union of a fractured mandible. Since then, the coronoid process with or without the ramus has been used in the following ways: after the release of ankylosis of the temporomandibular joint;2 for grafting of the maxilla, orbital floor, and nose; and augmentation of the sinus3 and alveolar ridge.4 The advantages of using this intraoral donor site are the absence of an extraoral scar and availability of donor bone bilaterally, with potentially minimal complications.
