Application of computer-assisted surgery techniques in the management of zygomatic complex fractures / 中华创伤杂志(英文版)

Patients suffering from zygomatic complex fractures always present facial deformity and dysfunctions, and thereafter develop psychological and physiological problems. It is really hard to get an ideal prognosis for the zygomatic complex fractures because of the complicated anatomical structures. Computer-assisted surgery techniques, as the new emerging auxiliary methods, can optimize the surgical protocol, predict operation outcomes, and improve the accuracy and quality of the operation. Meanwhile the postoperative complications can be reduced effectively. This review aims to provide a comprehensive overview of the application of computer-assisted surgery techniques in the management of zygomatic complex fractures.

Reduction and Fixation of Zygomatic Complex Fractures with Miniplates at the Fronto-zygomatic Suture and Zygomatic Buttress Area-A Clinical Study

Background Zygomatico-maxillary complex fractures are one of the most frequently occurring injuries of the facial skeleton due to its position and also the facial contour. The principal aetiologic factors that may result in zygomatic bone fracture include assaults, road traffic accidents and also falls. There are many methods of fixation that have been applied for treatment of zygomatic arch fractures. Aim To reduce and fix the zygomatic complex fracture using miniplates at the fronto-zygomatic suture and zygomatic buttress area. Material and method The present study includes five cases of zygomatic complex fractures who visited the Department of Oral and Maxillofacial Surgery in Government Dental College and Hospital, Hyderabad. The operative procedure adopted was the lateral bow incision for exposure of fronto-zygomatic suture, the Gillie temporal approach for reducing the zygoma and intra-oral incision for exposure of zygomatic buttress fracture. Fixation was done with miniplates at the fronto-zygomatic suture and the zygomatic maxillary buttress suture. Result All the cases were successfully treated without any post-operative complications and with uneventful restoration of aesthetics and function.

Isolated bilateral zygomatic complex and zygomatic arch fractures with oral submucous fibrosis: An unusual and rare case report.

Zygomatic bone forms major buttress of the facial skeleton and plays an important role in facial contour. Fractures of zygomatic complex are second most common only next to nasal bone fractures. Motor vehicle accidents and interpersonal violence are common causes. Bilateral fractures of zygomatic complex and zygomatic arch are very rare. We present a case report of isolated fractures involving bilateral zygomatic complex and zygomatic arch with oral submucous fibrosis, which is unique and first of its kind to be reported.

Atypical Typical Avulsion Zygomatic Bone Fracture / Fratura avulsiva atípica de zigona

Avulsion injuries of facial bones are rare, as well as accounts regarding the management of these lesions. This study describes a facial trauma that resulted from a bull gore, which caused the avulsion of the zygomatic bone, which was left hanging by only a small pedicle. The case study involved a 36 year old male leukoderma patient who sought the Maxillo-Facial Surgery and Trauma Department at the Emergency Unit in Pelotas-RS (Brazil). Clinical examination showed extensive laceration of the face in the middle third area on the left side, with the avulsion of the zygomatic body, causing the displacement of the eyeball towards the maxillary sinus. Treatment included bone and eyeball repositioning, zygoma fixation and suture, yielding good aesthetic and functional results. The peculiarity of the etiology and the particular features of the trauma are highlighted... (AU)

Lesões avulsivas dos ossos faciais são raras, assim como descrições quanto ao manejo dessas injúrias. Este estudo descreve um traumatismo facial decorrente de uma chifrada de um boi, que ocasionou a avulsão do osso zigomático, restando preso apenas por um pequeno pedículo. Trata-se de um paciente gênero masculino, 36 anos, leucoderma, que procurou o serviço de Cirurgia e Traumatologia Buco-Maxilo-Facial do Hospital de Pronto-Socorro da cidade de Pelotas-RS (Brasil). Ao exame clínico observava-se extensa laceração na face, em área de terço médio, lado esquerdo, com avulsão do corpo do zigoma, determinando o deslocamento do globo ocular em direção ao seio maxilar. O tratamento constou de reposicionamento ósseo e do globo ocular, fixação do zigoma e sutura, obtendo-se um bom resultado estético e funcional. Destaca-se a peculiaridade da etiologia e características únicas deste trauma... (AU)
