In
our study, we aimed to investigate spinal accessory nerve (SAN)
functions after neck dissections (ND), the effect of postoperative
radiotherapy (RT) on postoperative SAN dysfunction and the effect of
systemic peripheral neuropathy (SPN) on electromyographic (EMG) findings
of SAN dysfunction. Twenty patients who had undergone ND (35, in total)
in our clinic between December 1993 and September 1998 were studied
retrospectively using postoperative subjective and objective clinical
examination and EMG. All
patients answered a questionnaire regarding postoperative discomfort,
pain, limitation of shoulder movements and loss of daily activities.
Anatomical changes, degree of active abduction of the upper extremity
and muscle power were examined. After routine neurological examination
and routine EMG searching for any SPN, the SAN and the trapezius muscle
were examined with the EMG and results were classified as normal or
slight/intermediate/serious dysfunction. Three
cases with the SAN sacrified showed intermediate or serious dysfunction
in the EMG. Out of 32 cases with the SAN preserved, 22 (70%) showed
normal findings or slight dysfunction in the EMG. In both groups, SAN
dysfunction did not cause significant clinical findings and was not the
primary cause of loss of daily activities. Out
of 10 cases with intermediate-serious dysfunction in EMG, 5 also had
findings of SPN observed during routine EMG examination. In all these
cases, EMG results were not correlated to clinical symptoms and findings.
So one might suggest, that the presence of SPN may cause difficulties in
interpreting the EMG findings of SAN dysfunction, if it is overlooked. |
