Staged posterior fossa decompression and microvascular decompression for trigeminal neuralgia in autosomal dominant osteopetrosis type I: A case report

A staged decompressive approach represents an effective and durable treatment option for TN secondary to osteopetrosis, particularly in cases with markedly compromised posterior fossa anatomy. Initial posterior fossa decompression facilitates a safer and more effective subsequent microvascular decompression by improving the surgical corridor.
