Endoscopic cranioplasty with calcium phosphate cement for pterional bone defect after frontotemporal craniotomy: Technical note

OBJECTIVE: Postoperative pterional depression is a minor but unpleasant sequela of frontotemporal craniotomy. We developed a simple method for repair of this condition with the use of an endoscope and calcium phosphate cement. METHODS: The cranial defect was approached by means of endoscopic visualization through, a small incision, within the hairline. The defect was repaired with an injectable calcium, phosphate cement. RESULTS: The bone defect was easily accessed and readily repaired in all five patients. No adverse reactions to, the implant were;observed. Satisfactory cosmetic results were obtained in all patients treated with the use of this method. CONCLUSION: This minimally invasive cranioplasty technique proved to be effective for the repair of the postoperative pterional defect.
