Ultrasonically-guided biopsy in orbital tumors

Summary

In general ultrasonically-guided biopsy can be done more safely and accurately than that by the blind method. In ophthalmology ultrasonically-guided biopsy has not been common, due to orbital specific structure and limited manipulation of the B-mode probe.

A specific phantom was made, which consisted of a human skull specimen, commercial plain rubber balloons filled with gelatin gel, largely meshed sponge and spherical gelatin gel. The ultrasonic equipment we used was Ophthascan S.

Using the phantoms, the technique of ultrasonically-guided orbital biopsy was studied and its safety and accuracy were proved.
