Surgical Results of Zygomatico-Orbital Complex Fractures according to the 3-dimensional Classification

ABSTRACT

PURPOSE: To classify zygomatico-orbital fractures based on Zingg's classification and to evaluate the results of treatment. METHODS: Thirty patients who were diagnosed with zygomatico-orbital fracture between 2000 and 2004 were classified based on Zingg's classification, were treated and followed up for more than 3 months. Of the 30 patients, 28 received surgical treatment, including Gillies reduction or open reduction and rigid fixation with a microplate. RESULTS: The mean follow-up period was 6 months. Most of the patients were satisified with the results of surgery. There were no secondary operations due to facial asymmetry, secondary wound infection, microplate exposure or paresthesia. However, there were 3 re-operations for diplopia, enophthalmos, and lower eyelid retraction, respectively; the conditions had persisted until postoperative 2 weeks. CONCLUSIONS: The use of 3-dimensional Zingg's classification for zygomatico-orbital fractures appeared to be beneficial in making more accurate diagnoses and in determining surgical treatment. Oculoplastic approaches, including subciliary or transconjunctival incision, Gillies reduction and rigid fixation with a microplate, are considered to be good methods for the treatment of zygomatico-orbital fractures, as they are associated with exact anatomical and functional restoration and few complications.
