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.


CONCLUSIONS
This minimally invasive cranioplasty technique proved to be effective for the repair of the postoperative pterional defect.
