Reconstructing the jawbone using a new vascular technique

Mandibular Reconstruction Using Tissue Regeneration With Axially Vascularised Bone Substitutes

Not applicable Interventional University of Alexandria · NCT04001842

This study is testing a new way to rebuild the jawbone for patients with serious injuries or conditions to see if it helps the bone heal better and faster.

What this trial studies

This study focuses on reconstructing the mandible in patients with significant defects due to trauma, tumors, or infections. It employs a novel approach using axially vascularized bone substitutes, which aims to enhance blood supply to the reconstructed tissue through a microvascular arteriovenous loop. The study seeks to evaluate the effectiveness of this technique in promoting successful healing and integration of the bone substitute in the craniofacial region. By addressing the challenges of vascularization in large defects, this approach could potentially reduce complications associated with traditional reconstruction methods.

Who should consider this trial

Good fit: Ideal candidates are middle-aged adults (18-65 years) with mandibular defects of 6 cm or more that are tumor-free.

Not a fit: Patients under 18 or over 65 years old, or those with uncontrolled chronic illnesses, may not benefit from this study.

Why it matters

Potential benefit: If successful, this technique could lead to improved healing and functional outcomes for patients requiring jaw reconstruction.

How similar studies have performed: While similar techniques have shown promise in case reports, this specific application in the craniofacial region is novel and has not been extensively tested.
