[The value of studying the cervical spine in craniofacial asymmetries].

Introduction: The relationship between facial asymmetry and cervical anomaly is rarely mentioned in the diagnosis of dento-maxillo-facial orthopaedics. It is regrettable that the study of the cervical spine is often ignored in the etio-pathogenesis of these dysmorphoses, particularly in cases of facial asymmetry.

Objective: The aim is twofold: to encourage orthodontists and maxillofacial surgeons to make a systematic study of the cervical spine in craniofacial dysmorphoses and in particular craniofacial asymmetries, without claiming that they are becoming specialists in cervical spine pathology, and to introduce the necessary training in malformations of this anatomical region as part of the orthodontist specialisation curriculum.
