Subcaruncular Approach for the Reconstruction of Blowout Fractures of Medial Orbital Walls

초록

To obtain a wide and clean operative field for anatomic reconstruction of medial orbital blowout fractures, an alternative method called the subcaruncular approach has been performed. Between March 2008 and June 2010, this method was applied to the orbits of 41 patients with isolated pure medial orbital blowout fractures. A medial half conjunctival incision was made and extended meticulously to the subcaruncular area through preseptal plane under direct vision. Pre- and postoperative computed tomographic scans and ophthalmic examinations were performed, and clinical results were assessed. Postoperatively, computed tomographic scans revealed anatomic reduction of orbital soft tissues and the reconstructed medial orbital wall to be in proper position in all cases, and diplopia and eyeball motility limitation were resolved in most patients. There were no complications except severe chemosis in one case. We believe that this method can be a useful alternative option for the anatomic reconstruction of medial orbital blowout fractures.
