The Clinical Aspects of Blow-Out Fracture and Lyodura as an Orbital Floor Implants

ABSTRACT

From April 1989 to April 1993, 85 patients with orbital fractures were analysed. Among them, 10 patients were repaired surgically. Orbital fractures occured most frequently between the aga of 11 and 40 years. The main causes of injury were violence(41%), traffic accident (27%) and falldown injury (19%). Medial wall fractures were most common, followed by fractures of inferior wall, superior wall in order. In combined wall fracture, medial and inferior wall fracture was most frequent. The associated symptoms and signs of orbital fracture were lid laceration (32%), diplopia (29%). orbital edema(27%). traumatic iridocyclitis(22%). The subciliary approach was used for repair of the fracture. Early surgical intervention was done within 10 days in all cases. The insertion of Lyodura was performed in 9 patients. and calvarian bone graft was fashioned and placed over the defect in 1 patient. Insufficient correction of enophthalmos in 1 patient, lower eye lid retraction in 1 patient, residual diplopia in far upgaze in 2 patients were encountered as postoperative complications.
