  • Purpose: We investigated how nerve mobilization influence ankle plantar flexor muscles of the affected lower extremity on the spasticity in stroke patients. Method: Total 12 patients were recruited, who had spasticity on ankle of the affected lower extremity, and applied nerve mobilization on the sciatic and tibial nerves in supine position. H-reflex was measured using EMG equipment, detected the ratio of maximum H/M and H-reflex latency, and compared the changes before, during, right after, 5 minutes after and 10 minutes after the application of nerve mobilization. The data were analyzed using repeated measure ANOVA to compare the changes in length of time. Results: In comparison with the ratio before nerve mobilization, the ratio of maximum H/M was significantly decreased during nerve mobilization(p<0.05), and it tended toward recovery right after, 5 minutes after and 10 minutes after applying nerve mobilization, there was no statistically significant difference(p>0.05). In comparison with the ratio before nerve mobilization, the ratio of maximum H/M was most significantly decreased during the first 10 seconds after nerve mobilization and it tended toward recovery gradually(p<0.05). In comparison with the H-reflex latency before nerve mobilization, it was significantly increased during nerve mobilization(p<0.05) and it was decreased right after nerve mobilization, After 5 and 10 minutes, it had a tendency toward recovery but it revealed no statistically significant difference (p>0.05). Conclusion: It is considered that nerve mobilization could contribute to initial rehabilitation with stroke patients for relieving spasticity and nerve contracture.

  • Objectives : Peripheral nerve injuries are commonly encountered clinical problems and often result in severe functional deficits. The purpose of this study was to evaluate the effects of Haein-tang(Hairen-tang) extract on functional recovery and pain release in the sciatic nerve after crushed sciatic nerve injury in rats. Methods : 1. Sciatic functional index(SFI) were performed on functional recovery. 2. c-Fos immunohistochemistry were performed on c-Fos expressions in the paraventricular nucleus(PVN) and ventrolateral periaqueductal gray(vIPAG). 3. Neurofilament immunohistochemistry were performed on neurofilament regeneration. 4. Western blot were performed on brain-derived neurotrophic factor(BDNF) and nerve growth factor(NGF) expression. Results : 1. Haein-tang(Hairen-tang) extract significantly enhanced the SFI value in the sciatic nerve injury and 100 mg/kg, 200 mg/kg Haein-tang(Hairen-tang)-treated group. 2. Haein-tang(Hairen-tang) extract significantly suppressed the sciatic nerve injury-induced increment of c-Fos expressions in the PVN and vIPAG in the sciatic nerve injury and 100 mg/kg, 200 mg/kg Haein-tang(Hairen-tang)-treated group. 3. Haein-tang(Hairen-tang) extract significantly increased neurofilament expression in the sciatic nerve injury and 50 mg/kg, 100 mg/kg, 200 mg/kg Haein-tang(Hairen-tang)-treated group. 4. Haein-tang(Hairen-tang) extract significantly controled the sciatic nerve injury-induced increment of BDNF and NGF expressions in the sciatic nerve injury and 100 mg/kg, 200 mg/kg Haein-tang(Hairen-tang)-treated group. Conclusions : These results suggest that Haein-tang(Hairen-tang) treatment after sciatic nerve injury is effective for the functional recovery by enhancing of axonal regeneration and suppressing of pain.

  • Purpose: Schwannoma, a benign peripheral nerve tumor, is slow-growing, encapsulated neoplasm that originates from the Schwann cell of the nerve sheath. Schwannoma most frequently involves the major nerve. Schwannoma occurring in the superficial radial nerve rare. This is a report of our experience with schwannoma arising from the superficial radial nerve with neurologic symptom. Methods: A 55-year-old woman presented with eight-month history of progressive numbness and paresthesia in dorsum of the thumb and index finger. Physical examination revealed a localized mass on the midforearm. Sonographic examination showed an ovoid, heterogenous, hypoechoic lesion, located eccentrically in related to the superficial radial nerve. The lesion was mobile in the transverse but not in the longitudinal axis of the nerve, which was thought to favour schwannoma rather than neurofibroma. At operation, a $20{\times}15mm$ ovoid, yellowish grey mass was seen arising from the superficial radial nerve. The tumor present as eccentric masses over which the nerve fibers are splayed. Using operating microscope, the tumor was removed, preserving the surrounding nerve. Results: Histology confirmed that the mass was a benign schwannoma. There were no postoperative complications. After two months the patient had no clinically demonstrable sensory deficit. Conclusion: An unsusual case of a schwannoma of the superficial radial nerve is presented. In case with neurologic symptom, prompt surgical decompression must be made to prevent further nerve damage and to restore nerve function early.

  • Background: Transferring the hypoglossal nerve to the facial nerve using an end-to-end method is very effective for improving facial motor function. However, this technique may result in hemitongue atrophy. The ansa cervicalis, which arises from the cervical plexus, is also used for facial reanimation. We retrospectively reviewed cases where facial reanimation was performed using the ansa cervicalis to overcome the shortcomings of existing techniques of hypoglossal nerve transfer. Methods: The records of 15 patients who underwent hypoglossal nerve transfer were retrospectively reviewed. Three methods were used: facial reanimation with hypoglossal nerve transfer (group 1), facial nerve reanimation using the ansa cervicalis (group 2), and sural nerve interposition grafting between the hypoglossal nerve and facial nerve (group 3). In group 1, the ansa cervicalis was coapted to neurotize the distal stump of the hypoglossal nerve in a subset of patients. Clinical outcomes were evaluated using the House-Brackmann (H-B) grading system and Emotrics software. Results: All patients in group 1 (n= 4) achieved H-B grade IV facial function and showed improvements in the oral commissure angle at rest (preoperative vs. postoperative difference, 6.48° ± 0.77°) and while smiling (13.88° ± 2.00°). In groups 2 and 3, the oral commissure angle slightly improved at rest (group 2: 0.95° ± 0.53°, group 3: 1.35° ± 1.02°) and while smiling (group 2: 2.06° ± 0.67°, group 3: 1.23° ± 0.56°). In group 1, reduced tongue morbidity was found in patients who underwent ansa cervicalis transfer. Conclusion: Facial reanimation with hypoglossal nerve transfer, in combination with hypoglossal nerve neurotization using the ansa cervicalis for complete facial palsy patients, might enable favorable facial reanimation outcomes and reduce tongue morbidity. Facial reanimation using the ansa cervicalis or sural nerve for incomplete facial palsy patients did not lead to remarkable improvements, but it warrants further investigation.

  • Objectives : In parotidectomy, facial nerve dissection technique had been evolved for its safety. Surgical landmarks are important and good guides to facial nerve detection. Conventional exposure and release of the nerve requires hemostat for elevation of parotid tissue from nerve and #11 blade for cutting the parotid away from the nerve. Material and Methods : The rolling the parotid tissue over the nerve after dissecting with Metzembaum scissors instead of knife, lessen pulling trauma and nerve cutting by knife. Eleven superficial parotidectomies since June 2009 were done with rolling technique and preliminary report is presented. Results : Total 11 parotidectomies were done using proposed technique with tolerable complications(temporary facial dysfunction in 4 cases). Conclusion : Rolling method using metzembaum scissors could be applied to parotid operation.

  • Salivary duct carcinoma is a rare malignant salivary gland tumor that mainly has solid features. When it occurs in the parotid gland, it can invade the facial nerve and cause facial nerve paralysis. However, in our case, the salivary duct carcinoma exhibited cystic features on computed tomographic imaging, and the facial nerve passed through the cyst. Total parotidectomy with level-I to -III dissections was performed and nerve passing through the tumor was sacrificed. The patient received postoperative radiotherapy and was clinically and radiologically followed-up for every 3 months. Recurrence or distant metastasis was not reported. To the best of our knowledge, this is the first case involving a salivary duct carcinoma with cystic features and facial nerve invasion. Here, we report a first case of cystic salivary duct carcinoma of the parotid gland which uncommonly undergo cystic change and penetrated by facial nerve and successfully resected without causing facial nerve injury.

  • Femoral nerve injuries are devastating injuries that lead to paralysis of the quadriceps muscles, weakening knee extension to prohibit ambulation. We report a devastating case of electrical injury-induced femoral neuropathy, where no apparent site of nerve disruption can be identified, thus inhibiting the traditional choices of nerve reconstruction such as nerve repair, grafting, or transfer. Concomitant spinal cord injury resulted in spastic myopathy of the antagonist muscles that further restricted knee extension. Our strategy was to perform (1) supercharge end-to-side technique (SETS) to augment the function of target muscles and (2) fractional tendon lengthening to release the spastic muscles. Dramatic postoperative improvement in passive and active range of motion highlights the effectiveness of this strategy to manage partial femoral nerve injuries.

  • Rotator cuff tear is the most common cause of shoulder pain in middle-age and older people. Arthroscopic rotator cuff repair (ARCR) is the most common treatment method for rotator cuff tear. Early postoperative pain after ARCR is the primary concern for surgeons and patients and can affect postoperative rehabilitation, satisfaction, recovery, and hospital day. There are numerous methods for controlling postoperative pain including patient-controlled analgesia, opioid, interscalene block, and local anesthesia. Regional blocks including interscalene nerve block, suprascapular nerve block, and axillary nerve block have been successfully and commonly used. There is no difference between interscalene brachial plexus block (ISB) and suprascapular nerve block (SSNB) in pain control and opioid consumption. However, SSNB has fewer complications and can be more easily applied than ISB. Combination of axillary nerve block with SSNB has a stronger analgesic effect than SSNB alone. These regional blocks can be helpful for postoperative pain control within 48 hours after ARCR surgery.

  • This study examined the anatomical relationships along with the variability of the facial nerve trunk and its branches with an emphasis on the intraparotid connections between the divisions. And histomorphometric observations of the facial nerve branches and fascicles were performed on 40 Korean half-heads. The facial nerve trunk was bifurcated into two main divisions(35/40, 87.5%) and the other five cases were divided into a trifurcation pattern. According to the origin of the buccal branch, the branching patterns of the facia l nerve were classified into four categories. Communications between the facial and auriculotemporal nerve branches were observed in 37 out of 40 cases(92.5%). In the histological observation, the buccal branch had the greatest number of branches(3.47), however the zygomatic branch had the largest diameters(0.93mm). This detailed description of the facial nerve anatomy wi ll provide useful information for surgical procedures such as a tumor resection. a facial nerve reconstruction, autonerve graft. and facelift.
