Hydrophilic Hydroxyapatite Cement Cranioplasty: Preventing Cerebrospinal Fluid Leaks and Wound Complications in Translabyrinthine Acoustic Neuroma Surgery

Abstract

Objectives:

(1) Examine the efficacy of quick-setting, hydrophilic formulation of hydroxyapatite cement (HAC) used in cranioplasty for the prevention of cerebrospinal fluid (CSF) leaks and long-term wound complications following translabyrinthine acoustic neuroma (TLAN) surgery. (2) Review evolution of HAC cranioplasty.

Methods:

Retrospective case review from 2006 to 2013 in atertiary referral center. Consecutive patients undergoing translabyrinthine approach for acoustic neuroma tumors were operated on by the senior author. Intervention: Therapeutic: Cranioplasty combining a medial abdominal fat graft with hydrophilic hydroxyapatite cement filling the mastoid. Main outcome measures: Incidence of cerebrospinal fluid (CSF) leaks and any wound complications.

Results:

Forty-four patients met inclusion criteria. There were no CSF leaks or other wound complications in this series.

Conclusions:

Hydrophilic HAC appears to be safe and efficacious for cranioplasty following translabyrinthine acoustic neuroma surgery.
