Do We Need Three-Dimensional Computed Tomography in Maxillofacial Surgery?

In a retrospective clinical study (2000-2003), 121 patients' radiographs and computed tomography scans were reviewed to establish the clinical value of three-dimensional computed tomography. Eighty patients had computed tomography scans; 48 had three-dimensional computed tomography scans for diagnosing facial fractures, 3 for diagnosing temporomandibular joint ankylosis, 1 for tumor with bone destruction, and 1 for a mandibular cyst. It is concluded that axial, coronal, and three-dimensional computed tomography is of crucial importance and should be mandatory for all suspected comminuted and displaced midface fractures instead of plain radiographs. Three-dimensional computed tomography is also recommended for comminuted mandibular fractures and temporomandibular joint ankylosis. Three-dimensional computed tomography is not recommended for the diagnosis of minimally displaced fractures.
