A submental artery perforator flap was applied to the defect site after surgical excision of basal cell carcinoma on the right lower face. Three points were beneficial: it was perfect for assuring the safe margin of the mandibular branch of the facial nerve as well as intact platysma muscle, functionally; harvesting the flap was much easier than that of submental artery flap, surgically; and the color and contour were well matched aesthetically.

PURPOSE: The management of frontal sinus fractures and frontal sinus outflow tract (=FSOT) injuries is controversial. Traditional treatments include frontal sinus obliteration with a variety of material grafts, which all employ complicated algorithms for treatment planning. A simplified algorithm aiming for frontal sinus ventilation, however, can be achieved through the advanced technology of image guided endoscopic surgery and instruments. The authors explain this simplified treatment algorithm of frontal sinus fractures. METHODS: The authors reviewed articles on the management of frontal sinus fractures. RESULTS: Complicated treatment planning algorithms of frontal sinus fractures aiming for obliteration were replaced with a simplified algorithm aiming for ventilation of the frontal sinus. CONCLUSION: The authors suggest that a simplified algorithm can replace the complicated algorithms in selective cases.

PURPOSE: Within a clinically acceptable time frame, we obtained the high resolution MR images of the human brain, knee, foot and wrist from 3T whole-body MRI system which was equipped with the world first 3T active shield magnet. MATERIALS AND METHODS: Spin echo (SE) and Fast Spin Echo (FSE) images were obtained from the human brain, knee, foot and wrist of normal subjects using a homemade birdcage and transverse electromagnetic (TEM) resonators operating in quadrature and tuned to 128 MHz. For acquisition of MR images of knee, foot and wrist, we employed a homemade saddle shaped RF coil. Typical common acquisition parameters were as follows: matrix= 512x512, field of view (FOV) = 20 cm, slice thickness = 3 mm, number of excitations (NEX) = 1. For T1-weighted MR images, we used TR= 500 ms, TE = 10 or 17.4 ms. For T2-weighted MR images, we used TR=4000 ms, TE = 108 ms. RESULTS: Signal to noise ratio (SNR) of 3T system was measured 2.7 times greater than that of prevalent 1.5T system. MR images obtained from 3T system revealed numerous small venous structures throughout the image plane and provided reasonable delineation between gray and white matter. CONCLUSION: The present results demonstrate that the MR images from 3T system could provide better diagnostic quality of resolution and sensitivity than those of 1.5T system. The elevated SNR observed in the 3T high field magnetic resonance imaging can be utilized to acquire images with a level of resolution approaching the microscopic structural level under in vivo conditions. These images represent a significant advance in our ability to examine small anatomical features with noninvasive imaging methods.
