Great Auricular Nerve Injury After Ventriculoperitoneal Shunt Operation-Case report-
|
|
|
|
|
Abstract
|
|
|
The great auricular nerve injuries after the rhytidectomy, parotidectomy, mastolidectomy or in inserting the central venous line were previously reported. But great auricular nerve injury after the ventriculoperitoneal shunt operation was rarely
reported. We reported one case of great auricular nerve injury after the ventriculoperitoneal shunt in traumatic brain injured patient. A 32 year-old man sufferred from pain on right earlobe following a ventriculoperitoneal shunt operation for
obstructive hydrocephalus 4 months before visiting our service. Shock-like paresthesia could be triggered by touching or palpating the distribution of the right great auricular nerve Nerve conduction study using averaging 30 responses revealed
decreasing amplitude (peak to peak) of right great auricular nerve to 12 μV and slowing latency to 2.8 msec compared to 25μV and 2.0 msec relation on the left side. The great auricular nerve injury could be frequently occurred because of its
anatomical pathway of mid-point of sternocleiodomastoid muscle belly superficially crossing the course of ventriculoperitoneal shunt line. The great auricular nerve conduction study was helpful to identify the involvement in this case. Physicians
need
to be aware of the rilr f injury of great auricular nerve after the ventriculoperitoneal shunt operation.
