About this study

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.

Read the detailed description

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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • FSF with CAD\CAM customized cutting guideProcedure or surgery

    This began with the acquisition of a high-resolution CT scan of the patient's maxilla and scapula. The CT scan will be sent to the modeling company that produce 3D autoclavable models and cutting guides to be used during resection and scapular harvesting as well as a model of the final reconstructed maxilla.

    surgery will performed by two surgical teams one for tumor resection and the other harvesting the flap.

    access to the maxilla was obtained and the cutting guides were secured in the planned position; the cuts were completed. The scapular guides were secured to the harvested scapula to replicate the cuts that were planned previously.

    The scapula and plate will be fixed and pedicle anastomosis is performed. the operation then completed with soft tissue reconstruction.

  • FSF without customized cutting guideProcedure or surgery

    This began with the acquisition of a high-resolution CT scan of the patient's maxilla .

    The C.T scan will be sent to the modeling company for planning three-dimensional model of the maxilla. autoclavable model will be prepared to be used during the workflow for plate reshaping to conforme the prices position of the maxilla.

    surgery will performed in a single step by two surgical teams, one for cervicofacial resection and the other for harvesting the flap.

    Resection-reconstruction then performed in aconventional surgical manner with microvascular anastomosis. finally the operation will be completed with soft tissue reconstruction as needed.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Aesthetic

    aesthetic outcome will be measured objectively by computerized digital analysis as differential angle and differential area of reconstructed to other side of maxilla.subjectively will be evaluated using VAS.

    Measured: at least three months postoperative

Secondary outcomes (1)
  1. operation time

    operation time will be recorded intraoperatively in the surgery day as total operation time and ischemic time.

    Measured: intraoperative

Questions about this trial

What is this clinical trial studying?

A study testing FSF with CAD\CAM customized cutting guide and FSF without customized cutting guide in people with Maxillary Tumors, run by Cairo University 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 1 inclusion and 2 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?
