ObjectiveTo investigate the effect of neurolysis on intractable greater occipital nerve neuralgia.MethodsFrom March 1998 to August 2005, twenty-six patients suffering from intractable greater occipital nerve neuralgia were treated. There were 12 males and 14 females with an average age of 52 years (ranged 38-63 years). The disease course was 3-7 years. Sixteen cases had a long duration of work with bowing head, 5 cases symptoms appeared after trauma, and others had no identified causes. The visual analogue scales (VAS) scoring was 6.0 to 9.5, averaged 8. 6. Seven cases were treated by apocope of obliquus capitis inferior under general anaesthesia and 19 cases were treated by neurolysis of greater occipital nerve under local anaesthesia. The compression mass were examined.ResultsSymptoms ameliorated or disappeared in 26 cases immediately after operation. The wounds healed by first intention. The pathological results of the removal mass included lymph node (3 cases), neurilemmoma (2 cases) and scar (5 cases). The VAS scoring of 26 cases was 0 to 5 (average, 2) 3 days after operation. Twenty-three cases were followed up for 1 to 3 years. The VAS scoring of 23 cases was 0 to 4.5 ( average, 1.9) 1 months after operation. Only two cases recurred and the symptoms were ameliorated. Pain aggavated after tiredness and reliveed after oral anti-inflammatory analgesics in 6 cases. No relapse occurred in the others.ConclusionThe complete neurolysis of greater occipital nerve (including apocope of obliquus capitis inferior, release between the cucullaris and semispinalis) which make the greater occipital nerve goes without any compression is the key point to treat intractable greater occipital nerve neuralgia.
