Abstract Introduction The popularity and interest evoked by orthognathic surgery and distraction osteogenesis are undisputed in the field of oral and maxillofacial surgery. However, questions regarding the individual identities of either of them with clarity in their concepts, techniques and outcomes have remained unanswered. The aim of this review is to shed light on these questions. Methods This review is structured as a narrative review of thirty years of literature available in the specialities of orthognathic surgery and distraction osteogenesis. Conclusion The authors present a review of existing literature combined with contrasting experience gained over the years in providing an overview of the merits and demerits of the two surgical techniques which will aid the clinician in justifying the use of one technique over the other. & Manikandhan Ramanathan [email protected] Godwin Alex Kiruba [email protected] Amelia Christabel [email protected] Anantanarayanan Parameswaran [email protected] Sanjanaa Kapoor [email protected] Hermann F.

Background for This Review In the United States of America, there were about a hundred thousand patients operated for orthognathic surgery within a timespan of 9 years [1]. Since the first published case of Orthognathic surgery in 1849 [2] and the first report of Distraction osteogenesis in humans in 1992 [3], these surgical techniques have evolved significantly in many ways. Precious et al. [4] remarks that, ‘‘Orthognathic surgery consists of a constellation of procedures that permit differential alteration and repositioning of bone, cartilage, muscle, teeth, gingiva, mucosa, and skin’’, while distraction osteogenesis is described as a biologic process of new bone formation between the surfaces of bone segments that are gradually separated by incremental traction [5]. About 18 years ago, the first publication on the longterm results of distraction osteogenesis was published by McCarthy et al. [6], in which he elucidated his 11-year experience with mandibular distraction osteogenesis and summarized that it produced clinically favourable results. Later, Shaw et al. [7] did a critical appraisal of 88 studies on distraction osteogenesis and found that almost al
