Sino-orbital mucormycosis, especially with intracranial involvement, is a devastating infection affecting mostly immunocompromised patients. When combined with systemic therapy and surgical débridement, intraorbital amphotericin B infusion can be an important adjunctive therapy for orbital mucormycosis.1 Correct placement of the intraorbital catheter can be critical to proper drug delivery. We describe a technique using a barium-embedded neurosurgical catheter for intraorbital drug delivery. Intraoperative fluoroscopy can also be used to assess and adjust catheter tip placement to achieve optimal results.

Surgical technique and results. A, Radiopaque catheter was used to facilitate visualization. Ten-millimeter marks on the catheter can be used to aid in localization. The Innervision Ventricular Catheter (Medtronic, Inc, Minneapolis, Minnesota) is 15 cm long and made of translucent silicone elastomer containing a barium-impregnated stripe. B, Placement of the intraorbital catheter and externalization through a lateral stab incision. C, Catheter placement after closure. Sagittal (D) and coronal (E) computed tomographic scans of patient 1 revealing excellent position of the radiopaque catheter tip. Sagittal (F) and coronal (G) computed tomographic scans of patient 2 showing the catheter (asterisk) curving inside the orbit and pointing away from the orbital apex. H and I, Intraoperative fluoroscopy allows for localization of the catheter tip. H, Sagittal view before the infusion of iohexol. I, Immediately after iohexol infusion. The infusate (arrow) can reveal the direction of fluid spread.
