Abstract:
砄bjective: To study the cause,clinical characteristics and treatment of zygomatic complex fractres(ZCF). Methods: Medical records of 79 cases with ZCF and followed up for 3 months to 2 years were reviwed and analysed. Reduction and cosmatic outcome were assessed by clinical evaluation and postoperative images. Results: Of the 79 patients, 87.3% were male, with the peak incidence in the age group from 20 to 40 years old(73.5%). 58.2% were due to traffic accidents, 15.2% to assalts. Incidence of malar asymmetry, enophthalmos, diplopia,limited mandiblar movement and malocclusion were 83.5%,24.1%,19.0%, 60.8% and 35.4% respectively. Of the nerve disturbances, 41.8% of the infraorbital and 13.9% of the facial nerve were involved. For the treatment the most freqently used approach was the coronal incision in combination with the maxillary vestibular incision(30.4%), followed by coronal incision alone(22.8%). 40.5% of the patients were treated by rigid internal fixation with titanium miniplates alone or combined with wire fixition(20.3%). All patients but five regained satisfactary facial appearance. Three patients still showed slightly post surgical enophthalmos and diplopia at a 6 month follow up. All of the patients with malocclusion regained their functional occlusion after treatment. Conclsions:A variety of techniques can be used in the treatment of ZCF. Among them the coronal incision in combination with other incisions or alone and rigid internal fixation can produce a satisfactary outcome.
