The aim of this study to assesment the effect of using titanium mesh to repair isolated monolateral blow- out orbital fractures. The research sample comprised 15cases reported to the Department of ophthalmology and department of oral and maxillofacial surgery at Alassad University Hospital Latakia-Syria , the time between trauma and procedure of surgery was taken into account. The clinical observation contained studying of eye movement , vertical localization of eyeball, diplopia through15 day, month, and 3month after the surgery . The enophthalmos was monitored also through: 3 months ans 6 months after the surgery Results showed that there is statistical difference before and after the surgery operation. Eye movement returned completely normal after 3 months, the localization of injured side of eyeball returned natural when compared to the localization of intact side, and diplopia was corrected through the catamnesis Using Titanium mesh in repairing blow- out fractures led to improve the functional side of eyeball, so this important part of face was returned functionally and esthetically.
