Other Neurovascular Compression Syndromes in the Cerebellopontine Angle
摘要
This chapter reviews other cranial rhizopathy syndromes different from classical trigeminal neuralgia. Hemifacial spasm, glossopharyngeal neuralgia, vestibulocochlear dysfunction, masticatory hemispasm, and neurogenic arterial hypertension are among these syndromes, which are rather uncommon compared with trigeminal neuralgia. The pathophysiology is the same as in trigeminal neuralgia, that is, the microvascular compression of the entry zone of the cranial nerve root at the pontocerebellar angle. The treatment is the same, microvascular decompression. The anatomy of the cranial nerve roots related to the compression, as well as the offending vascular elements, is reviewed in detail. In neurogenic arterial hypertension, it is postulated that microvascular compression occurs in the rostral–ventro–lateral region of the medulla oblongata. The clinical characteristics, microsurgical technique, results, and outcomes of each syndrome are presented.
