“…Whether dissection and anastomosis are performed with loupe or operative microscope, appropriate focus depth, fi eld size, and lighting are indicated. Microscopic magnifi cation that is placed on the surgeon's head (Varioscope) has recently developed [ 15 ]. When compared to the operating microscope, loupes are cost effective, portable and easier to use.…”

“…The device enhances the freedom of movement in microsurgery, and its use in free tissue transfers has been reported. 4 The combination of its magnification and strong illumination promises a better visualization of skin alterations. The goal in BCC resection, especially in the face, is complete tumor eradication with minimal sacrifice of healthy tissue.…”

Complete resection with minimal sacrifice of healthy skin is the goal in treatment of basal cell carcinoma (BCC) of the face. In a randomized trial, preoperative assessment of tumor extension with the Varioscope, a combination of microscope and loupe glasses with strong illumination and a maximal magnification of 7X, was compared with tumor assessment without. Forty consecutive, primary BCC of the solid subtype of the face were randomly assigned to the study groups. Preoperative tumor marking was done by a surgeon not involved in tumor resection, reconstruction, and patient follow-up. All BCC marked with the high magnification were completely excised in the first resection. In the control group, frozen section was used in 12 tumors and permanent section in the remaining 8. The first resection did not yield tumor-free margins as assessed in the frozen section analysis in 3 tumors. In 2 of 8 tumors not supported by frozen section analysis, incomplete excision was detected, and 1 case of false-negative frozen section analysis occurred. In conclusion, the use of high magnification resulted in a trend towards reduction of positive tumor margins in the subgroups that were performed under either intraoperative frozen section or permanent, fixed section histology control, and a significant reduction in tumor-positive margins of all first resections. This was attributed to enhanced preoperative tumor visualization by high (7X) loupe magnification and additional lighting.

A new type of magnification system in free microvascular tissue transfer: Varioscope M5

Free microvascular tissue transfers have become today a key instrument for the surgical treatment of wide loss of tissue. These procedures can provide definitive treatment in a single operation but they are expensive and require specialized practitioners. The operating microscope traditionally has provided this requirement; our study is focusing on the prospect of using a new visual system-Varioscope M5-in the reconstructive microsurgery field. Varioscope M5 (Life Optics, Vienna, Austria) has been employed in 21 microvascular anastomoses, where different free flaps were used in head and neck reconstruction. The necessity to operate in a different department, not provided with an operating microscope, brought along the idea of exploring an alternative procedure to classical visualization systems. Specific advantages such as reduced cost, freedom of movement, autofocus, minimal upkeep, a variable range of magnification from 2x to 9x are some of the reasons that convinced the authors to use this new type of magnification system. Increasing interest in microsurgery magnification highlights the need for further technical development in that field. We consider Varioscope M5 a future mean of anastomotic magnification in most free-tissue transfers with specific characteristics that combine the microscope and loupe philosophies.
