Objective:
To update the outcome of hydroxyapatite cement cranioplasty in translabyrinthine acoustic neuroma (TLAN) surgery.
Patients:
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.
Intervention(S):
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.
Main Outcome Measure(S):
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.
Conclusion:
Hydroxyapatite cranioplasty is a reliable method to avoid CSF leaks after TLAN surgery.
