Development of Oro-Facial Structures and Its Clinical Correlations

Overview

The justification for knowledge in this area is because facial anomalies are frequent conditions in children in every part of the world. If these anomalies are not treated appropriately and adequately, there will be imposition of severe psychosocial problems on the parents of such children. And, the appropriateness and adequacy of the definitive treatment, which is often surgery, lie in the proper understanding of the anatomic and embryologic bases of these anomalies. You will therefore agree with me that this lecture is very important to the practice of oral and maxillofacial surgery.

Introduction

 

This module includes video presentation on the development of oro-facial structures and it's clinical correlations. Each animated outline in the slides to be projected for the lecture has been made into video lessons and the outlines will be made to be as representative as possible of what are in their respective video.

 

After going through the video lessons, there will be a link after the under this menu, that will direct you to an assignment page.

 

The clinical aspects will be taught at 500 and 600 Levels, while at the same time integrating it with the basic aspects i.e. the embryology will be revisited. The teaching process will be by audio enhanced lectures, tutorials, video clips on clinical demonstrations as well as video clips on surgeries of various types of facial clefts.

 

All the teaching materials may be downloaded onto CDs or flash drives for students to access them frequently.

 

Objectives

 

At the end of this lesson, students should be able to:

 

Describe and illustrate the pre-embryonic period of human development, which are at weeks 1-3.

Describe and illustrate the development of brachial arches, the face and palate.

Enumerate various types of facial clefts with illustrations.

Describe and illustrate the development of the tongue.

Describe and illustrate the development of the mandible and the fate of Meckel’s cartilage.

Describe the growth of the mandible.

Describe and illustrate the development of maxilla.

Tabulate the derivates of branchial arches.

Diagnose various types of facial clefts images.
