The coronoid process for paranasal augmentation in the correction of midfacial concavity
1Department of Oral and Maxillofacial Surgery, and Brain Korea 21 Human Life Sciences, College of Dentistry, Seoul, Korea.
Objective:
The coronoid process can be easily harvested as a donor bone by an intraoral approach during orthognathic surgery, especially during mandibular ramus surgery. This study was performed to provide an objective assessment of the coronoid process as a candidate material for paranasal augmentation.
Study Design:
The dimensions of the coronoid process and the paranasal area were directly measured in 15 dry skulls. Based on these data, the coronoid process was used for a paranasal augmentation in 54 patients.
Results:
The size and shape of the coronoid process was found suitable for paranasal augmentation; its thickness was 5.4 +/- 0.8 mm on the right and 5.8 +/- 1.2 mm on the left. All patients showed improved facial esthetics without complications when followed up for more than 12 months.
Conclusion:
The coronoid process seems to be suitable for paranasal augmentation in the dry skull study. Its clinical application is also favorable because its size and morphology fits into the paranasal region, with the additional advantages of biocompatibility, availability, and reduced operation time for harvesting.

01:14Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
01:27Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
