Reported are a total of 81 microsurgical operations for cranial nerve
root decompression comprising of 66 trigeminal, 10 facial, one vestibular,
one vagus and three accessory nerve dysfunction syndromes from 1983 to
1990.
Almost all cases of trigeminal neuralgia (TNG) secondary to vascular
(59 cases) and minute mass (10 cases) compression, and those with hemifacial
spasm (HFS) (nine out of 10 cases) recovered with microsurgical
decompression of these nerves. A comparison of results of different
treatment modalities of TNG are discussed. Some recently reported series in
the literature indicate the superiority of microvascular decompression
(MVD) of the 5th nerve for the treatment of TNG. MVD of the 7th nerve has
currently been accepted as a procedure of choice, albeit with reservations, in
managing HFS.
Despite our effective surgical outcome and satisfactory results obtained
by others with MVD of the 8th, 10th and 11th nerves, long-term follow up of
selected cases may further clarify the r9le of MVD on caudal cranial nerves.
