Abstract

PURPOSE
To evaluate the extent of lesion by using ultrasound biomicroscopy in eyelid tumor. METHODS: We retrospectively analyzed 17 patients with eyelid tumor, who had undergone preoperative ultrasound biomicroscopy to access the extent of the lesion and the depth of involvement, excision and biopsy. These data were compared to the histopathologic findings. RESULTS: On ultrasound biomicroscopic examination, the eyelid tumor showed greater homogeneous hypoechoic density or heterogenous echo density than that of the surrounding tissue, leading to identifying the lateral margin of the lesion and depth of involvement. The mean maximum thickness of the lesion measured by ultrasound biomicroscopy was 2.26 +/- 0.49 mm and that of the histopathologic depth was 2.22 +/- 0.56 mm. Linear regression demonstrated that lesion depth measured by ultrasound biomicroscopy was correlated with histopathologic depth. CONCLUSIONS: In eyelid tumor, ultrasound biomicroscopy is helpful in assessing the extent of the lesion and the depth of involvement preoperatively, and in obtaining good postoperative results.
