Abstract

The purpose of this work is to describe the technique of double-stage genioplasty and to bring out its interest in the important retromicrogenia l and its feasibility in the context. The study provides a descriptive and cross sectional study with prospective data collection, conducted in the department of Maxillofacial and Aesthetic Surgery of the Mohammed 6 Teaching Hospital of Marrakech, on two patients who have benefited a double-stage genioplasty. These are two clinical cases of retromicrogenia. The first (patient1) is subject to temporo-mandibular ankylosis, and the second (patient2) is subject to congenital with growth disorders of the dental arch, a tendency to class-II skeletal patterns, pro-alveoli, swallowing problems, and occurrence of recurrent mouth infections due to poor oral hygiene. They were treated, respectively, with double-stage genioplasty only and a combined procedure of double-stage genioplasty associated with Wassmund osteotomy at the same time. The patients were female, young on average 24 years of age. The average duration of the intervention was 1h10 minutes; the mandibular advances were on average 8mm per fragment. The dental articulation and the projection of the chin were satisfactory. Retromicrogenia is a rare pathology, the source of functional and morphologic complications. “Double-stage” advancement genioplasty is the treatment of choice. It allows a necessary advancement for a good reflection of the chin, and remains a simple technique, minimal, and ensuring good aesthetic and functional results over the long term.
