OBJECTIVE: To describe a new craniotomic technique that eliminates burr holes and minimizes bone loss along the craniotomic line. PATIENTS AND METHODS: Fifty burr hole free craniotomies were performed in varied locations using an image-guided micro-oscillating saw. Care was taken to avoid cutting the inner cortical layer. Upon completing the micro-oscillating saw cut the inner table could then be gently fractured along the craniotomic line with a thin bladed osteotome. Simple silk sutures were used to resecure the bone flap. RESULTS: The craniotomic time required for this procedure ranged from 7 to 24 minutes (mean: 13 minutes). We observed no dural lacerations or signs of brain damage in any of these procedures. The use of image guidance allows a continuous measure of bone thickness along the craniotomic line. In all of the cases we report the cosmetic result was excellent. CONCLUSION: This alternative technique of craniotomy can be used in selected cases to achieve excellent cosmetic results which avoid the time and cost of complex reconstruction techniques.
