Correction of Severe Post-traumatic Enophthalmos through Transconjunctival Approach

ABSTRACT

Surgical treatment of post-traumatic enophthalmos is one of the most challenging procedures following facial injury. The purpose of this study is to evaluate the advantage of transconjunctival approach and/or medial and lateral extension in reconstruction of orbit in patient with severe post-traumatic enophthalmos. This study includes 7 patients. All operative procedures were performed through preseptal transconjunctival approach and/or medial and lateral extension. After release of scar tissues around orbital contents, reconstruction of orbit was performed using titanium dynamic mesh and silastic sheet. In 5 patients, repositioning of the malunited zygoma was done as concomitant surgery. The aesthetic and functional results were satisfactory. The results were good in 5 patients(72%) and fair in 2 patients(28%). Postoperative improvement of enophthalmos and ocular dystopia were statistically significant by paired t-test(p-value<0.05). No patients complained of postoperative lower lid ectropion. Finally, this approach is much advantageous in patient with severe post-traumatic enophthalmos as wide exposure of lesion and no visible scar on lower lid.
