A lack of control in the deep margin of shave excision is a drawback of this technique.
To describe a more precise shaving technique by sonography with the use of a fine injector needle as a depth marker.
After having examined the invasion levels of 40 benign skin lesions, a fine injector needle was intentionally threaded into the dermis horizontally just beneath the required shaving plane. Correct placement of the needle was ensured by sonographic examination after possible reinsertion trials. Large lesions needed several needles to be inserted. The tissue above the needles was then shaved off, whereas the deep dermal layer was protected.
Histologic examination revealed that 77% of superficial and intermediate-thickness lesions were removed totally without disturbing the derma-fat junction.
The needle-guided technique was found to be effective in the control of the deep margin of shave excision.
削除术切缘深部缺乏控制是该技术的一个缺点。
描述一种使用细注射针作为深度标记物的超声引导下更精确的削除技术。
在检查40例良性皮肤病变的浸润深度后，将一根细注射针水平穿过真皮，置于所需削除平面下方。在可能的重新插入试验后，通过超声检查确保针的正确放置。大的病变需要插入几根针。然后刮除针上方的组织，同时保护深部真皮层。
组织学检查显示，77%的浅表和中厚层病变被完全切除，且未累及真皮-脂肪交界。
发现针引导技术在控制削除术的深部切缘方面有效。
