This x ray shows the classic transition zone.
Ct scan orbital floor mesh.
This confirms that there is no need for further corrections in this case.
In intervention group n 5 the ct scan slices were used for generating 3d reconstruction of both affected and unaffected orbits.
For most orbital fractures the imaging study of choice is ct scan.
Postoperative ct scan analysis shows that all treatments restored orbital volume and.
Psi placement over failed pre bend mesh.
A ct scan with axial and coronal views is optimal.
The overlying colored line in the medial wall and orbital floor area indicate the preoperative virtual planning that is superimposed on the mesh reconstructed area.
Before the advent of high resolution ct several articles were published in the radiology literature debating the need for direct sagittal views which required cumbersome patient positioning.
These plates consist of implants that closely approximate the topographical anatomy of the human orbital floor and medial wall and are intended for use in a selective craniomaxillofacial trauma.
Orbital fractures pose specific challenge in its surgical management.
The correct anatomic shape of the titanium mesh used for orbital floor reconstruction can be verified in the intraoperative ct scan.
The sagittal plane computed tomographic ct scan has been proposed as the most important radiologic view in the diagnosis of orbital floor fractures.
This study was prospectively conducted on 10 patients with unilateral orbital floor fractures caused by accident or falls.
The matrixmidface preformed orbital plates are designed from ct scan data.
Coronal slice of a postoperative ct scan taken after transconjunctival repair of the complete left medial orbital wall and orbital floor.
The aim of this study was to describe t.
Surgical treatment was performed using subciliary inferior palpebral approach to explore the orbital floor and placement of the titanium mesh and an intraoral antrostomy for endoscopy to magnification of the surgical field and adaptation of the mesh.
6 7 see the image below.
One of the greatest challenges is to obtain satisfactory reconstruction by correct positioning of orbital implant.
Ask for thin cuts 2 3 mm with specific attention to the orbital floor and optic canal.
To design implants for orbital reconstruction rapid prototype models can be derived from digital imaging and communications in medicine dicom data obtained from the patient s computed tomography ct scan.
Intraoperative computed tomography ct scan may facilitate this procedure.
