USING CRANIAL SUTURES IN A SINGLE-STEP FRAME-GUIDED RESECTION AND RECONSTRUCTION FOR INTRAOSSEOUS MENINGIOMAS: TECHNICAL NOTE
Introduction, Objectives, Methods, Results, and Conclusion.
INTRODUCTION: Single-stage surgical treatment of cranial intraosseous meningiomas includes complete tumor resection followed by aesthetic reconstruction. Tailored tumor resection with a computer-aided design/computeraided manufacturing custom-made implant for the defect has been advocated in recent years to achieve a satisfactory cosmetic result with reduced operative time and fewer complications. However, several technical nuances related to the area of osseous removal may compromise cranioplasty.
OBJETIVES: Describe a surgical frame template based in cranial sutures for removal and reconstruction of intraosseous tumors in a single stage.
METHODS: We present 2 cases of intraosseous meningiomas(sphenoid wing and retromastoid) to illustrate a step-by-step approach, from preoperative planning to single-step surgery.
RESULTS: For each case, a customized frame template delimiting bone removal was designed using cranial sutures as anatomical landmarks for precise placement of the cranioplasty template over the area of interest.
CONCLUSIONS: Custom templates based in cranial sutures may benefit single-step frame-guided resection and reconstruction of intraosseous tumors with compelling results.
