Maxillary Tumors Clinical Trial
Official title:
Aesthetic Reconstruction of Onco-surgical Maxillary Defects Using Free Scapular Flap With and Without CAD/CAM Customized Osteotomy Guide (A Randomized Controlled Clinical Trial)
The aim of the study is to compare aesthetic results and operation time of Free Scapular flap with and without CAD/CAM customized osteotomy guide for reconstruction of maxillary Defects.
Maxillofacial defects create unique challenges for the reconstructive surgeon, often
involving bony and soft tissue components of the midface. Surgical reconstruction following
maxillectomy is currently a topic of interest for reconstructive head and neck surgeons.
maxillary defects were reconstructed with maxillofacial prosthetics including obturation.
While the latter is an effective reconstruction. Over the past two decades, there has been
increasing interest in the use of free tissue transfers of bone to reconstruct the maxilla.
Scapular flap It is an excellent candidate for maxillectomy defects because of its unique
feature, which is characterized by additional skin paddles or muscles. and can be harvested
along with a part of the scapular bone for bony reconstruction
Traditional reconstructive techniques often lead to suboptimal reconstructions due to inexact
planning, poor communication between the resective and reconstructive teams or surgical
difficulties in adjusting a free flap and osteosynthesis plates into a three-dimensional (3D)
defect without the help of any templates or surgical guides The advent of 3D modeling in head
and neck reconstruction has allowed surgeons to improve upon functional and aesthetic
outcomes, which are crucial to patient satisfaction and can be difficult to achieve in
maxillectomy defects The cutting guides used or not used, however debate still present for
its benefits and worth for patient and surgeon. current study to evaluate how such virtual
planning with using of customized cutting guide is effective and worth for patient aesthetic
and operation time.
our priori-hypothesis is that utilization CAD/CAM assisted with customized osteotomy guide is
not related to an altered result regarding aesthetic outcome and operation time in patient
undergoing maxillary reconstruction using free scapular flap.
In order to test this hypothesis, we will compare aesthetic outcome and operation time in
group of patients receive FSF by CAD/CAM-assisted with customized osteotomy guide to results
of another group of patients receive FSF but without customized osteotomy guide. only model
will be performed as conventional method aiding in reshaping of reconstruction plate which is
another well-established concept of management of maxillary defect.
