OBJECTIVE: A versatile neurosurgical approach, the retrosigmoid craniectomy (RS) has traditionally been associated with high rates of post-operative cerebrospinal fluid (CSF) leak, headaches, and aesthetic defects. We introduce a simple surgical strategy for bony cranial reconstruction designed to minimize peri-operative complications and improve cosmetic outcomes.
METHODS: In accordance with the Institutional Review Board, the senior author's (G.M.M.) records were queried between 2006 and 2014. We identified 50 consecutive patients who underwent demineralized bone matrix (DBM)-augmented cranioplasty after RS for MVD (DBM group) and 92 consecutive patients in whom standard cranial reconstruction was undertaken using autologous bone chips only after RS for MVD (non-DBM group). Demographic and clinical information regarding the laterality of each operation, intra-dural drilling for petrous hyperostosis, method of dural closure, length of hospitalization, presence of post-operative headaches, and procedure-related complications were collected and analyzed.
RESULTS: The DBM and non-DBM cohorts were well matched for age, laterality of procedure, surgical indications, primary versus revision surgery, intra-dural drilling of petrous hyperostosis, and dural closure techniques. Trigeminal neuralgia was the most common surgical indication (98.6%) in each cohort. Post-operatively, 15% of patients in non-DBM group experienced chronic headaches at the last follow-up compared to only 8% of the patients in the DBM group (p=0.21). The non-DBM patients also suffered more incisional pain in comparison to the DBM patients (7.6% vs. 0%, p=0.045).
CONCLUSION: DBM-augmented reconstruction of posterior fossa defects resulted in low rates of post-operative headaches, better cosmetic outcomes, and represents a simple and effective cranioplasty option for skull base surgeons.
