[Correction of enophthalmos deformity caused by orbital blow-out fractures using medpor implantation].

Abstract

OBJECTIVE:

To study the surgical reconstruction for correction of enophthalmos deformity caused by orbital blow-out fractures.

METHODS:

From December 1996 to March 2004, 56 cases of enophthalmos deformity caused by orbital blow-out fracture were repaired. There were 37 cases diplopia, 35 cases with worsened visual acuity than pre-trauma. Typical sub-ciliary incision was employed to expose the fractured area. The dissection was done beneath the medial and inferior orbital periosteum. The fracture areas were exposed and the tissues protrusion to maxillary sinus were released through the space between fractured bones. After the medial and inferior orbital walls and orbital floors were exposed,the herniated orbital contents were released and reduced to the orbital cavity. The fractured orbital walls were repaired precisely with Medpor which were fixed to the area beneath the periosteum with 2 plates at least.

RESULTS:

All 56 cases of enophthalmos deformity caused by orbital blow-out fracture repaired with this technique recovered well and their facial appearance improved greatly. With a follow-up ranged from 2 months to 5 years, the degree of enophthalmos stabilized at within 2 mm, no relapse and other complications occurred. Of 34 patients with diplopia, 27 were improved. Of the 35 cases with worsened visual acuity, 9 were improved with different degree. No diplopia or visual acuity worsening occurred.

CONCLUSION:

It is safe and effective to correct the orbital blow-out fractures. The earlier it is repaired, the better the effect will be. Medpor with its advantages like better histocompatibility, easier sculpturing, moderate hardness, lower absorptivity, fewer complications and permanence effect is the preferable implantation material for correcting enophthalmos deformity.
