Surgical treatment of proptosis bulbi by three-wall orbital decompression.

PURPOSE: Three-wall orbital decompression was tested using a coronal approach as a technique.

PATIENTS AND

METHODS

Three-wall orbital decompression by a coronal approach was performed in three patients with proptosis due to Grave's ophthalmopathy, in six patients with Grave's ophthalmopathy because their vision was threatened due to optic nerve compression, and in one patient with exorbitism due to Crouzon's syndrome for cosmetic rehabilitation.

RESULTS

Proptosis reduction averaged 4.7 mm. The technique provides good access to the orbital walls, facilitating adequate proptosis reduction, and leaves no visible scar. Diplopia, present preoperatively in four patients, was improved in three patients and unchanged in one. There was no loss of visual acuity.
