What this trial studies

This clinical trial aims to evaluate the effectiveness and stability of different surgical techniques for transverse maxillary expansion in patients with maxillary hypoplasia. It compares segmental Le Fort I osteotomy (SLFIO) with various fixation methods, including bone block grafts and biodegradable plates, as well as surgically assisted rapid maxillary expansion (SARME) using different distraction appliances. The study will involve 90 patients who will be randomly assigned to different treatment groups, and outcomes will be assessed through clinical and radiographic measurements.

Who should consider this trial

Good fit: Ideal candidates for this study are mature, non-syndromic patients scheduled for transverse expansion of the maxilla.

Not a fit: Patients who have previously undergone orthognathic surgery involving the maxilla or have congenital maxillofacial deformities may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved surgical techniques for maxillary expansion, resulting in better long-term stability and outcomes for patients.

How similar studies have performed: While various surgical techniques for maxillary expansion have been explored, this study systematically compares different fixation methods and distraction appliances, making it a novel approach.
