Area of Science:

Oral and Maxillofacial Surgery
Reconstructive Surgery
Bone Grafting Techniques

Background:

Maxillofacial deformities require advanced reconstructive solutions.
Autogenous bone grafts are crucial for successful reconstruction.
The mandibular ramus and coronoid process offer a viable donor site.

Purpose of the Study:

To assess the effectiveness of autogenous extended mandibular ramus and coronoid process bone grafts.
To evaluate their utility in various maxillofacial reconstructive surgeries.

Main Methods:

A retrospective study of 12 patients (aged 23-76) undergoing extended ramus/coronoid process grafts.
Reconstruction of maxillofacial deformities including nasal, mandibular, and maxillary defects.
Combined unilateral or bilateral coronoid process-mandibular ramus bone grafts were utilized.

Main Results:

Successful reconstruction of all patient deformities ('ad integrum').
High success rate for endosteal implant placement in augmented areas.
One donor site infection resolved with conservative management; nasal reconstruction restored function and symmetry.

Conclusions:

Autogenous bone grafts from the coronoid process and mandibular ramus are suitable for maxillofacial reconstruction.
This technique provides adequate bone quantity and quality for selected cases.
The procedure demonstrates high success rates and functional restoration.
