Chin wing: Technical note

Edité par CCSD ; Elsevier Masson -
International audience. The chin may be concerned by morphological abnormalities in its various dimensions. Classical genioplasty techniques can be used to correct these but have some disadvantages. The "chin wing", described by Triaca, is a technique of genioplasty extended to the mandibular angles, considering the mandibular basilar border as an anatomical unit, thus achieving a better harmonious functional and aesthetic result. The preoperative assessment included a mandibular Cone Beam to evaluate the position of the inferior alveolar nerve. The procedure was performed under general anesthesia. The periosteal dissection was limited to the osteotomy area and mental nerves were protected. The osteotomy observed a modification of its orientation in front of the mental foramen to become parallel to the basilar border, which was interrupted at the level of the mandibular angle. The spaces created were filled with bone grafts and maintained by a symphysary plate. Chin wing genioplasty both improves the function and aesthetic of the face because it considers the mandibular basilar border as an entire anatomical unit. It can be performed independently of any procedure to modify the bone bases. Nowadays, chin wing remains a challenging technique hardly performed.Copyright © 2017 Elsevier Masson SAS.
