About this study
Official title: Comparison of Two Different Modalities for Orbital Reconstruction Based on CAD-CAM Technology: A Clinical Randomized Trial
Reconstruction of orbital defects resulting after trauma; tumor resection; maxillary cyst; craniofacial anomalies and sequestrated bone…. etc., has been a challenging issue over the years and this owing to the complicated anatomy of orbit. Inaccurate orbital reconstruction may lead to devastating cosmetic and functional complications. Titanium mesh for orbital reconstruction has now become "probably" the most popular material for orbital wall reconstruction worldwide. Innovation of CAD-CAM technology and its application in maxillofacial surgery will markedly improve the surgical outcome. This study will assess the accuracy of orbital reconstruction using CAD-CAM technology and to compare two different modalities for orbital reconstruction based on this technology.
Read the detailed description
This study will be a prospective cohort study. It will include patients treated with the custom-made implants for orbital blow out fractures, ZMC fractures or tumors. The sample will consist of 34 patients who will need orbital reconstruction and will be operated in Maxillofacial, Head and Neck Unit, General Surgery Department, Faculty Of Medicine, Sohag University, Egypt. The patients will be randomly divided into two groups, group (A) reconstructed with patient specific implant and group (B) reconstructed with preformed plate preoperatively bended on stereolithographic model. The reconstructive outcomes are assessed by clinical and ophthalmological examinations and accuracy analysis by comparing the preoperative and postoperative multi slice computed tomography data. All patients will be assessed clinically, ophthalmologically, and radiographically using computed tomography (CT) then virtual surgical planning and custom-made patient implant will be manufactured. Post-operative clinical evaluation will be done, and radiographic evaluation of all patients will be done by CT scan within one week and 6 months after the procedure. comparing data of the two groups will be done using appropriate methods.

Questions about this trial
What is this clinical trial studying?
A study testing orbital bone reconstruction with patient specific titanium implant and orbital bone reconstruction with preformed titanium plate preoperatively bended on stereolithographic model in people with Orbital Bone Fracture and Maxillary Cyst, run by Hatem Adel Aboelhassan at 1 site in Egypt.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 30 Jun 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Hatem A Abo El Hassan El Shazly, MMed (+201002760859 ext. +201114455343, hatem_adel_post@med.sohag.edu.eg), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
measurement of Changes in orbital bony volume (time frame: preoperative and one week and 6 months post-operative). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05438784, which also lists 9 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Jun 2022.
