Hydroxyapatite cement cranioplasty in translabyrinthine acoustic neuroma surgery-update.
OBJECTIVE
To update the outcome of hydroxyapatite cement cranioplasty in translabyrinthine acoustic neuroma (TLAN) surgery.


METHODS
One hundred eight previously reported patients undergoing abdominal fat graft reconstruction versus hydroxyapatite cement cranioplasty with additional 4-year follow up. Ninety additional patients undergoing a uniform technique of hydroxyapatite cement cranioplasty after TLAN.


METHODS
After TLAN, strips of abdominal fat are placed through the dural opening and medial to the level of the mastoid antrum, filling the lateral mastoid cavity.


METHODS
Cerebrospinal fluid (CSF) leaks and wound complications.


RESULTS
No additional CSF leaks or wound complications were identified in the patients included in the previous report. In the new series of 90 consecutive patients, there was one CSF leak.


CONCLUSIONS
Hydroxyapatite cranioplasty is a reliable method to avoid CSF leaks after TLAN surgery.
