Neurosurgical involvement in XXXX of the orbit.

The neurosurgeon has a great deal to offer in the therapy of @entity5 . Dr. Dandy's supposition that all @entity5 could be approached by the intracranial route is certainly correct, but technical advances have made the medial and lateral approaches to the orbit more useful for most @entity5 which are confined to the orbit (22, 25). For those which involve the posterior orbit and canal and have intracranial extensions, the intracranial approach is excellent. Since Dandy's first description of the procedure in 1922, there have been 29 @entity1 reports concerning the results of transcranial canalicular decompression for non-traumatic causes. The most common diagnosis was @entity1653 (15), and other @entity5 diagnoses were @entity82 (7) and @entity2695 (2). One-third of the @entity1 were improved; one-third had vision stabilized; and one-third were made worse by surgery. Modern techniques with the @entity3178 and high speed drill have greatly improved these results. Our own experience in the decompression of 15 canals in 11 @entity1 is as follows. There were six @entity1 with @entity1653 , and two were bilateral. Three @entity1 were found to have a vascular dolichoectasis and one @entity1 had an @entity2695 , and in two @entity1 no compression was identified. Immediately postoperatively, two-thirds of the @entity1 were improved, and only one eye (representing 6.7% of the nerves decompressed) was worsened. This resulted from an attempt to totally remove an adherent @entity1653 . Long-term follow-up median 34 months has demonstrated maintenance of these gains. Eighty percent of the @entity1 have improved or remained stable. These data indicate that the procedure described can be done safely without major risk of @entity227 . The neurosurgeon should play an increasingly important role in the evaluation and therapy of posteriorly placed @entity5 and unexplained @entity1781 .
