Measuring orbital Volume Using Open Source Software and its Application in Orbitozygomatic Fractures.

Study Design: Technical note. Objective: Changes in orbital volume can lead to esthetic and functional complications of the orbit. In this article, the procedure to calculate the orbital volume using the open source software Aliza 3D DICOM is described. Methods: This article describes the steps to use this novel software. To validate the software, the normal orbital volume was calculated bilaterally on CT scans with normal orbital anatomy. The volumes of unilateral orbitozygomatic fracture cases were compared. Results: This open source software has easy access. The normal orbital volume calculated using this software was 24.4 cc ± 0.72. In the unilateral orbitozygomatic fracture cases, an increased orbital volume was calculated. Conclusions: This easy access, inexpensive, and convenient computer aided software can be used to calculate orbital volume facilitating treatment plan for correction of the orbit volume.

Surgical management of garre's osteomyelitis in an 8-year-old child.

Chronic non-suppurative osteomyelitis, also known as Garre's osteomyelitis is a well-described pathologic entity in dental literature. We present here a case report of a unilateral hard bony swelling of the lower jaw associated with infection. Radiograph revealed the pathognomic feature of 'onion skin' appearance. Surgical recontouring of the lower jaw was performed since there was no evidence of bone remodelling after removal of the infected tooth.
