Intraoperative magnification: Who uses it?

Abstract

Surgeons over recent decades have made increasing use of intraoperative magnification to enhance the outcome of surgical procedures, yet no published information exists regarding the extent of magnification use within surgical specialties. A sample of surgeons consisting of 148 specialists and senior surgical trainees in the west of Scotland was surveyed by postal questionnaire regarding their frequency and types of magnification use. Patterns of use were similar within each specialty, but varied markedly between specialties. Otolaryngologists and plastic, maxillofacial, and ophthalmic surgeons use both loupes and microscopes frequently. Cardiothoracic and pediatric surgeons tend only to utilize loupes, whereas neurosurgeons tend only to use microscopes. General surgeons, urologists, orthopedic surgeons, and gynecologists are infrequent users or nonusers of magnification, and when required will utilize loupes rather than microscopes. As a clear pattern of magnification use exists, it should be possible to anticipate the equipment needs of surgeons when providing theater services.
