    Author: Arriaga MA, Chen DA, Burke EL.
    Journal: Otol Neurotol; 2007 Jun; 28(4):538-40. PubMed ID: 17414174.
    Abstract:
    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.
