Glomus tympanicum (GT) is a benign primary tumor of the middle ear. The evolution of endoscopic ear surgery has allowed for an alternative approach to managing this vascular tumor. The purpose of this study was to evaluate an endoscopic approach in GT surgery, and also to investigate its applicability and feasibility.

Materials and Methods:
Prospectively, 3 class Ipatients, according to the Glasscock-Jackson glomus classification, were candidates for management via a transcanal endoscopic approach. Under specially designed flap elevation and hemostasis, the tumors were completely removed using an endoscopic technique.

No change was detected in bone conduction after surgery, but air conduction was improved in all cases. No major complication or recurrence was observed over 24 months of follow up.

Improved exposure and access in the endoscopic transcanal approach to GT leads to safe, rapid, and reliable tumor removal, as well as allowing comfortable surgery for both the surgeon and most patients.
