Objective: The aim of this study is to evaluate shoulder function and preoperative and postoperative electrophysiological changes related to the spinal accessory nerve with reference to neck dissection technique. Materials and Methods: We evaluated shoulder function by pain, strength and range of motion in a total of 35 neck dissection cases of 29 patients with head and neck cancer or thyroid papillary cancer. Electrophysiologic studies were performed before surgery, after third postoperative weeks and 6 months respectively. The results of each test according to the types of neck dissection were compared. Results: Clinical parameters of shoulder function and electrophysiologic study showed deterioration in early postoperative periods and improvements in late postoperative periods when the spinal accessory nerve was spared and permanent nerve damage was observed in radical neck dissection. There were correlations between the clinical parameters and electrophysiologic studies. Conclusion: The shoulder function after spinal accessory nerve sparing procedure is better than the function after nerve sacrificing procedure.

With the wide range of movement, the movement of neck accompanies the body surface change of neck and shoulders. And neck corresponds to the collar of garment, meaning that the body surface change of this part affects the construction of patterns for collars. So the purpose of this study was to manifest the changes of body surface in the neck and shoulder accompanied with the movement of the neck and to draw up the facts worth consideration when constructing the collar pattern. In this study, the draft of body surface of neck and shoulder was drawn up by gypsum method according to the 5 movements (standing at attention, neck bending - front, back, right, left). The length of body surface was measured and analyzed by ANOVA, post hoc test, correlation and regression analysis using SPSS 10.0 for Windows. The variation of the surface of neck was remarkable in the vertical lines than the horizontal ones. So the height of collar should be established considering the range of movement of the neck. It was the raising amount of c.f(center front) of neck and girth of neckbase (back) that were proved to have significantly varied after movement. With correlation analysis done, in every movement, the raising amount of side and the girth of neckbase had remarkably positive relation. The movement of the neck accompanied the variation of body surface in the shoulder as well. It was the part of scapula and side of neckbase that the variation was notable, suggesting that the surplus is needed in these parts.

Postural instability can increase the likelihood of hazardous slip and fall accidents in workplaces. The present study intended to extend understanding of the effect of abnormal neck posture on postural control during quiet standing. The effect of body fatigue on the postural control was also of primary concern. Twelve healthy undergraduate students volunteered to participate in the experiment. Standing on a force platform with the neck neutral, flexed, extended, or rotated, subjects' center of pressures (COP) were measured under the two levels of body fatigue. For the fatigue condition, Subjects exercised in a treadmill to meet the predetermined level of body fatigue. Analyzing the position coordinates of COPs, the length of postural sway path was assessed in both medio-lateral (ML) axis and anterior-posterior (AP) axis. Results showed that, in AP direction, neck extension or rotation significantly increased the sway length as compared with neck neutral. Neck extension led to greater sway length compared to neck rotation. Neck flexion did not differ from neck neutral. The sway length in the AP direction also became significantly larger as the body fatigue accumulated after treadmill exercise. In ML direction, as compared to neutral posture, the neck extension, flexion, or rotation did not significantly affect the length of postural sway path. However, the sway length seemed to increase marginally with the neck extended during the fatigued condition. This study demonstrates that abnormal neck posture may interfere with postural control during standing. The ability to maintain postural stability decreases significantly with the neck extended or rotated. Body fatigue leads to postural instability further.

Purpose : It is necessary to demonstrate the effect of non-invasive and non-pharmacological interventions such as manual therapy and therapeutic exercise for the management of nonspecific neck pain. In the present study, we aimed to investigate the efficacy of myofascial release therapy plus therapeutic exercise for disability owing to neck pain and quality of life in individuals with nonspecific neck pain. Methods : Eighteen participants with nonspecific neck pain were randomly allocated to intervention (n=9) and control groups (n=9). The intervention group received a myofascial release therapy for 20 min and performed neck stabilization exercises for 30 min twice a week for 4 weeks. The control group performed neck stabilization exercises for 30 min twice a week for 4 weeks at the same time points as the intervention group. Disability owing to neck pain and quality of life were quantified using the neck disability index (NDI) and the Korean version of the World Health Organization Quality of Life Brief Version (WHOQOL-BREF), respectively. NDI and WHOQOL-BREF were assessed before and after intervention. Results : The disability owing to neck pain significantly changed between the groups over time (total score of NDI, p=.049). There were significant time and group interactions in pain (pain intensity of NDI, p=.035) and concentration (concentration of NDI, p=.049). Personal care, lifting, reading, headaches, work, driving, sleeping, and recreation did not show significant improvement between the groups over time. Total score, overall quality of life and general health, physical health domain, psychological domain, social relationships domain, and environmental domain quantified by WHOQOL-BREF did not show significant improvements between the groups over time. Conclusion : These results suggest the clinical use of myofascial release therapy in addition to therapeutic exercise for the management of nonspecific neck pain. Further studies are needed to generalize the findings of this study.

Background: Neck pain is a major health problem in developed countries and has a lifetime prevalence of 50%. Major problems include a reduced cervical range of motion, muscle stiffness, dysfunction, postural changes, and decrease in psychosocial level. Objects: This study aimed to investigate the effects of applying the upper trapezius inhibition dynamic taping to patients with chronic neck pain on their neck pain, functional level, cervical range of motion, psychosocial level, and neck posture. Methods: The study design was a randomized controlled trial. A total of 40 patients with neck pain participated in this study and were randomly assigned to a Dynamic Taping group (n = 20) or Sham Taping group (n = 20). In both groups, basic intervention cervical pain control therapy and shoulder stabilization exercise program were performed. In addition, dynamic taping and sham taping were applied to participants in the Dynamic Taping and Sham Taping groups to inhibit the trapezius muscle, respectively. All interventions were performed three times a week and a total of 12 times for 4 weeks, and the participants' neck pain, functional impairment level, cervical range of motion, psychosocial level, and neck posture were measured and compared before and after the intervention. Results: Both groups showed significant differences in neck pain, functional level, cervical range of motion, psychosocial level, and neck postural before and after the intervention (p < 0.05). Moreover, there were significant differences between the two groups regarding the functional level and neck posture (p < 0.05). Conclusion: Inhibition dynamic taping of the upper trapezius muscle suppression is an effective method with clinical significance in reducing pain in individuals with chronic neck pain and improving the functional level, cervical range of motion, psychosocial level, and neck posture.

Background: The purpose of this study is to investigate the effect of neck and shoulder self-stretching exercise using audiovisual media on neck pain, postural alignment, and joint position error in women with chronic neck pain. Methods: The subjects included 20 women that gave consent to participate in the study voluntarily. They performed the self-stretching exercises using audiovisual media was carried out 20 minutes 5 times a week during 3 weeks. Neck disability index (NDI) and visual analogue scale (VAS) were used to measure the functional disability and pain, A pressure pain threshold was measured using an algometer, and a cervical range of motion (CROM) measurement tool was used to measure the range of motion and error of proprioceptive position sense of the cervical spine. To assess posture alignment, forward head angle (FHA), forward shoulder angle (FSA) were measured using image J software. Results: The neck pain intensity was statistically significantly within group (p<.05). Neck and shoulder functional disability were a statistically significant difference within group (p<.05). Splenius capitis and upper trapezius pressure pain threshold were statistically significant difference in within group (p<.05). The postural alignment was statistically significantly within group (p<.05). The cervical range of motion in neck extension, right and left lateral flexion were statistically significantly within group (p<.05). The joint position error in neck flexion, extension, right and left lateral flexion decreased statistically significantly within group (p<.05). Conclusion: Self-stretching exercise using audiovisual media increased the mobility of the neck, decreased neck pain and joint position error, and improved posture alignment. As a result, there was a positive effect by applying the self-stretching exercise using audiovisual media to people with neck pain. Based on this, it is thought that it can be used as the basis for research related to home training programs for healthy self-management.

저자들은 변형적 경부청소술을 시행받은 두경부암환자 23례를 대상으로 술 후 내경정맥의 유지여부을 후향적으로 연구한 결과 총 34측 경부청소술 중 28측(82.4%)에서 내경정맥이 유지됨을 알 수 있었다. 이는 기존의 연구결과와 비슷한 개존율임을 알 수 있었다. 내경정맥의 폐쇄요인으로 술중 정맥의 손상과 혈류정체, 장기간 수술로 인한 정맥벽의 건조, 수술시 제거되는 근막의 소실이 정맥의 유착과 압박을 초래하는 것으로 알려져 있다. 또한 다양한 치료방법과 술 후 발생하는 여러 요인들에 의해 내경정맥이 영향을 받는데 본 연구에서는 국소재발과 창상합병증등이 주된 영향을 준 것으로 판단된다. 방사선치료는 다른 복합적인 요소가 결부되어 단독적인 영향으로 판단하기엔 충분치 않으며 양측 경부청소술은 내경정맥의 폐색과는 무관한 것으로 생각된다. 본 연구는 증례수가 작고 추적기간이 짧은 한계점이 있으므로 향후 좀 더 많은 증례와 충분한 추적기간을 통한 연구가 필요하리라 판단된다.

Background: Penetrating neck injuries are potentially dangerous and require emergency management because of the presence of vital structures in the neck. The risk of airway, vascular, neurological, and pharyngoesophageal injuries leads to many difficult diagnostic decisions. The purpose of this retrospective study is to evaluate our experience with management of penetrating neck injuries, and to assess treatment outcome. Material and Method: Forty-two consecutive patients were identified (26 patients from Korea university Ansan hospital, 16 patients from Guro hospital) as having penetrating neck injuries from 2003 to 2009. With review of medical records, variables were collected and evaluated including the location of injury, mechanism of injury, number of significant injuries, diagnostic modalities, duration of hospital stay and outcome. Results: The location of injury was zone I (lower neck) in 13 cases (31%), zone II (midportion of the neck) in 22 (52%), and zone III (upper neck) in 7 (17%). Injuries were caused by stab wounds in 23 patients, penetrating foreign bodies in 12. Among 35 patients who had deep injuries that violated the platysma, significant injuries, including major vascular (20), trachea (5) Pharyngoesophageal injuries (5) were identified in 24 patients. The mean hospital stay was 9.5 days. Conclusion: The penetrating trauma in the neck may show various degrees of severity. However, Cervical penetrating injury should not be underestimated in spite of the minimal width of the lesion.

This study aims to suggest the proper neck-width of slim-fit jackets according to numbers of jacket buttons from an one-button jacket to a four button jacket for men in their 30's. The researchers carried out both an appearance evaluation and a movement functionality evaluation. When analyzing the appearance evaluation, there were meaningful differences. The one-button jacket showed a high score on the back-neck width of +2.4cm. The two-button jacket and the three button jacket showed a high score on the back-neck width of +1.4cm. The four-button jacket showed a high score on the back-neck width of +0.4cm. The result of movement functionality evaluation was not related to the appearance evaluation, and showed no meaningful difference. The one-button jacket and two button jacket showed high scores on the back-neck width of +2.4cm. The three button jacket showed a high score on the back-neck width of +1.4cm. The four-button jacket showed a high score on the back-neck width of +0.4cm. In analyzing both results, the study suggests that the proper front neck-width and that of the back-neck width of +2.4cm be for the one-button jacket, the back-neck width of +1.4cm be for the two-button jacket and the three-button jacket, while the back-neck width of +0.4cm be for the four-button jacket.

Background and Objectives: Because of squamous cell carcinoma of the head and neck undergoes a generally poor hospital course, the prognostic significance of the squamous cell carcinomas in head and neck have been evaluated to identify those features associated with aggressive biologic behavior according to the immunologic and histopathologic characteristics. Materials and Method: To assess the significance of EGFR, c-erbB-2, p21 and p53 protein in head and neck tumors and their correlation with prognostic factors, samples from 74 patients with squamous cell carcinomas of larynx, pharynx, and oral cavity were studied immunohistochemically. Results: EGFR, c-erbB-2, p21, and p53 protein were expressed 94.6%, 24.3%, 85.1%, and 55.4% in 74 cases of head and neck squamous cell carcinoma, respectively. The positive expression of EGFR was associated significantly with clinical stage and the negative expressions of p21 was associated significantly with histopathologic differentiation. There were no significant relationships between the reactivity of EGFR, c-erbB-2, p21, and p53 protein. Conclusion: The expression of EGFR, c-erbB-2, p21 and p53 protein could be related to oncogenesis, and the expression of p21 and EGFR protein can be used as a prognosticator in head and neck squamous cell carcinoma under certain limitations, but c-erbB-2 and p53 protein expression alone is not enough for evaluating prognosis of the carcinoma.
