  • Title: Osteoplastic lateral suboccipital approach for acoustic neuroma surgery.
    Author: Sepehrnia A, Knopp U.
    Journal: Neurosurgery; 2001 Jan; 48(1):229-30; discussion 230-1. PubMed ID: 11152354.
    Abstract:
    OBJECTIVE: Persistent headache remains a significant problem in a small group of patients after acoustic neuroma surgery via the lateral suboccipital approach. We describe a modified technique of osteoplastic lateral suboccipital craniotomy for surgery of the cerebellopontine angle. This simple and elegant technique provides a superior cosmetic result and a significant reduction in patients' symptoms. METHODS: We report on our series of 75 patients who underwent surgery for acoustic neuroma. The maximal follow-up period was 4 years. RESULTS: No patients reported headache postoperatively. Cerebrospinal fluid fistulae were not observed. CONCLUSION: This modified approach minimizes cerebellar retraction, and the neural and vascular structures can be preserved under direct visualization of the tumor. This lateral suboccipital approach is a useful modification of previous approaches in acoustic neuroma surgery. It provides successful tumor resection and excellent functional results.
