Comparative Study
Inclusion of asymptomatic degenerative discs in a two-level anterior cervical discectomy and fusion: a decision analysis.
To perform a decision analysis model to compare single-level fusion versus two-level fusion in patients with an asymptomatic disc adjacent to a symptomatic disc. ⋯ Observation was the preferred strategy for management of asymptomatic adjacent degenerative discs (AADDs) given the probabilities and utilities used in the decision analysis model. The study was limited by unavailability of precise estimates of the probability of development of ASD and the probability of surgery after diagnosis of ASD, the most critical factors influencing the decision. However, the conclusions were robust given wide ranges used for these parameters in the sensitivity analysis.

Schwannomas of the abducens nerve are extremely rare tumors. The tumor may be located within the cavernous sinus or more often at the prepontine region. However, literature research has identified only one case of isolated schwannoma of the orbit, arising from the terminal branches of the abducens nerve to the lateral rectus muscle. This is only the second report of an abducens nerve schwannoma located entirely intraconal. ⋯ Being a benign lesion, one of the goals has always been total removal. The knowledge of the correct anatomic features made us believe that the VI nerve function could be preserved. Our case is the first example of a total removal with eye abduction preserved. Because of that, we believe that it is reasonable to aim for these goals in future cases.
