To the Editor: We thank Meola and Chang for their thoughtful and well- informed review of our manuscript “Navigation-Linked Heads- Justin R. Mascitelli, MD Up Display in Intracranial Surgery: Early Experience.” We Joshua B. Bederson, MD are in agreement that our study plus others in the literature Department of Neurosurgery demonstrate feasibility of use but not necessarily effectiveness Barrow Neurological Institute as judged by operative room efficiency and patient outcomes. Phoenix, Arizona In our experience, the major limitations are (1) a cumbersome Department of Neurosurgery setup for typically nonmicroscopic portions of the procedure (skin Mount Sinai Health System incision, soft tissue dissection, craniotomy, and dural opening); New York, New York (2) the distractibility of objects injected into the microscope and associated learning curve; and (3) loss of accuracy for REFERENCES deep lesions. Despite these limitations, the heads-up display, or 1. Meola A, Chang SD.
