Introduction: Surgical endodontic procedures require precise knowledge of anatomic structures that might be traumatized. The aim of this study was to evaluate whether differences in patient gender or age are predictive of differences in the relative location of the inferior alveolar nerve (IAN) compared with the roots of the mandibular first molar.
Methods: We searched a database of 23,000 small-volume cone beam computed tomography scans and evaluated the first 200 patients that met the following inclusion criteria: (1) age between 30-69 years; (2) known gender (n = 25 males and 25 females for each 10-year age bin); and (3) scans containing the mandibular first molar and IAN.
Although penetrating orbital wounds are an uncommon entity they are often associated with vision and life-threatening complications. By careful attention to the history and physical signs of the injured patient and the use of modern computed tomography (CT) scan imaging, the physician will be better able to make an accurate analysis and prognosis of the problem at hand as well as a well-planned therapeutic approach.

In the past decade there has been considerable controversy over the surgical indications for treatment of blowout fractures of the orbit. It has been well recognized that some fracture patients develop an ischemic contracture of the inferior rectus muscle. We have found that a Volkmann's type of contracture of the inferior rectus muscle does exist and is similar to that found in the distal extremities.
