Background: For the elderly, masticatory function is one of the most important oral functions and the masticatory ability is related to the wearing of dentures. Many older people wear dentures for their masticatory function, but a significant number of older people who use dentures have found that they feel uncomfortable when performing their daily activities, such as performing masticating functions or talking. Objects: The purpose of this study is to investigate how the forward head posture (FHP), respiratory function and thickness of masseter (MS), and sternocleidomastoid (SCM) are affected by the presence or absence of dentures in the elderly, and what kind of correlation there is between these variables. Methods: The study was conducted on 11 patients in the normal group and 13 in the denture group. The participant's cognitive ability was evaluated using Mini-Mental State Examination Korean (MMSE-K), and the FHP was evaluated by measuring the craniovertebral angle (CVA). The thickness of the MS and SCM muscles were measured using ultrasound, and respiration was measured with a spirometry. As for the statistical method, the correlation of each variable was investigated using Spearman's correlation coefficient. Results: In the normal group, there was a significant correlation between forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV1) (p < 0.001), and in the denture group, FVC and FEV1 (p < 0.001), maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) (p < 0.001), CVA and Lt. MS (p = 0.012). Conclusion: CVA and Lt. MS of the denture group have a high negative correlation, it is related that the thickness of MS may be thick when the elderly wearing dentures are FHP.

Spinal accessory neuropathy (SAN) is commonly caused by an iatrogenic procedure, and that caused by tumors is very rare. We present a case of a 49-year-old man suffering from weakness in the right trapezius and sternocleidomastoid muscle. An electrophysiology study confirmed proximal SAN. Fluorodeoxyglucose (FDG)-positron emission tomography (PET)/computed tomography (CT) revealed a diffuse large B-cell lymphoma compressing the right spinal accessory nerve. Ultrasonography showed definite atrophy on the trapezius and sternocleidomastoid muscles. In addition, post-chemotherapy FDG-PET/CT showed increased FDG uptake in the right upper trapezius, suggestive of denervation. This is the first report of SAN caused by direct compression by a diffuse large B-cell lymphoma, comprehensively assessed by an electrophysiology study, ultrasonography, and FDG-PET/CT.

Accessory tragus is an uncommon congenital anomaly of the external ear. The tragus derives from the first branchial arch. The accessory tragus can be found along the entire course of embryonic migration. Usually it appears as a small papules arising near the tragus, but rarely, along an imaginary line drawn back from the tragus to the angle of the mouth, or along the anterior edge of the sternocleidomastoid muscle and the sternoclavicular region. We experienced a case of accessory tragi on the suprasternal region in an 9 year-old-boy.

The aim of this study was to investigate the efficacy of treatment with thread-embedding therapy for 24 patients with hemifacial spasm (HFS). The muscle spasm of these patients was treated with thread-embedding therapy. Patients with nuchal pain were treated with tendino-musculature acupuncture in the sternocleidomastoid, splenius, and trapezius muscles. We evaluated the treatment effect using the Scott's scale, where 20, 3, 1, and 0 patients presented Scott's grade 0, grade 1, grade 2, and grade 3, respectively. The grade of the spasm intensity decreased noticeably after treatment. The results revealed that the Scott's grade changed to 0 in 83.3% of HFS patients, and 91.7% patients felt satisfied with thread-embedding therapy. These findings suggested that thread-embedding therapy was effective and can be used widely for HFS.

Electromygram was measured in three different cases; not wearing of a helmet, wearing of a 920g helmet, and wearing of a 1310g helmet, and it was revealed that there was a high level of muscle activities on the opposite side (sternocleidomastoid muscle) while the head and the neck were moving right and left and muscle activities of the curve and of the hyperextension were found to be not significant. Especially, the presence of a helmet seemed to cause a difference in a level of muscle activities on the deltoid and erector spine muscles while lifting or lowering with a weight placed on the deniz backboard. Therefore, it would be possible to assume that this newly developed smart helmet would not affect muscles around the necks of paramedics if they do not move their necks and heads right and left while lowering or lifting a patient using the deniz backboard. In addition, in case of the deltoid and erector spine muscles, it is shown that an increase in the degree of movement could lead to an increase in the level of muscle activities on the muscles controlling of the corresponding action, which are waist and back muscles. Despite it, it would be possible to prevent possible injuries and/or muscular and skeletal diseases around the lumbar by fully complying with a basic rule of straightening of the waist while making a power-lifting motion.

This study was performed to investigate the effects of changes of head posture and cervical spine shape on the mandibular resting or clenching electromyographic(EMG) activity in anterior temporalis(TA), masseter(MM), sternocleidomastoid muscle(SCM) and trapezius insertion(TI). 30 patients with Temporomandibular Disorders(TMDs) participated in this study. EMG activity($\mu$V) at rest and clenching was observed in four head postures, namely natural head posture(NHP), forward head posture(FHP), upward head posture(UHP), and downward head posture(DHP). For taking in upward or downward head posture head was inclined 10$^{\circ}$ upward or downward and CROM$^\textregistered$(cervical-range-of motion, Performance attainment Inc., USA) was used to maintain same posture during the procedure, and BioEMG$^\textregistered$ (Bioelectromyograph, Bioresearch Inc., USA) was used to record EMG activity in the above four muscles at eight locations on both sides. The recorded EMG activity($\mu\textrm{V}$) were compared and analyzed by cervical spine shape such as the head position from plum line, cervical curvature, and cervical inclination. Head position from plum line was measured in vertical plate calibrated with cm scale, comical curvature by radius was measured with adjustable curved ruler, and cervical inclination by cervical vertebrae tangent(CVT)was measured in lateral cephalograph. The results obtained were as follows : 1. Mean value of head position from plum line, cervical curvature, and cervical inclination were 4.8cm, 26.7cm, and 86.6$^{\circ}$, respectively, And There were no correlationship among these items. 2. For resting EMG activity by head posture, the value in anterior temporalis was higher at FHP than at DHP, the value in masseter was higher at FHP than at NHP, and DHP, the value in sternocleidomastoid muscle was higher at UHP than at NHP, and the value in trapezius insertion was higher at FHP and DHP than, NHP and UHP. The clenching EMG activity, however, did not show any difference by head posture. 3. Comparison of resting and clenching EMG activity between higher and lower groups by head position from plum line, cervical curvature, and cervical inclination did not show any significant difference. From this result, the author concluded that the cervical spine shape had not significantly affected to EMG activity in usual patients with TMDs.

The purpose of this study was to investigate the correlation between ultrasonographic findings used to diagnose and assess of torticollis and a overall special assessment of congenital muscular torticollis in infants. Seventy-eight subjects with congenital muscular torticollis participated in this study. All the patients were divided into one of four clinical types according to the sternocleidomastoid muscle fibrosis noted on the ultrasonographic findings, and they were divided into one of three subgroups according to the degree of disability on the overall special assessment score of torticollis. For the ultrasonographic classifications of the 78 patients, 42(53.8%) made up the first type, 21 (26.9%) made up the second type, 7 (9.0%) made up the third type, and 8 (10.3%) made up the fourth type. Multivariate analysis of the results showed that the age at presentation was significantly different according to the ultrasonographic subtypes (p<0.01). There was significant correlation between the ultrasonographic findings and the torticollis overall assessment for patients with congenital muscular torticollis (${\phi}$=0.893, p<0.01). According to the results of this study, the use of the simple and objective torticollis overall assessment will be useful for the evaluation of torticollis in the future.

Background and Objective：A post-operative hypertrophic scar of the anterior neck is the leading complaint of the patients who underwent conventional thyroid surgery. In order to minimize the post-operative scar of the anterior neck, we performed thyroidectomy via axillary approach using operating microscope and a specialized retractor to determine technical feasibility. Patients and Methods：From January 2005 to December 2006, we performed thyroidectomy via axillary approach under operating microscope(f=400mm, ${\times}2.5$；OPMI $pico^{(R)}$；Zeiss, Germany) for benign unilateral nodule in 25 cases(all female, average age 34.5yrs). Under general anesthesia less than 7cm of skin incision was made in the axilla of ipsilateral side. A subcutaneous tunnel went over the pectoralis major muscle and the clavicle, and then through the sternocleidomastoid muscle and sternothyroid muscle was excised. The area around the thyroid was sufficiently dissected, and then a retractor designed for exposure via axillary approach was placed within the tunnel and under operating microscope thyroidectomy was performed. Results：There were 17 cases of thyroid nodulectomy and 8 cases of subtotal lobectomy. The mean average operative time was 102.64minutes. Postoperative complications included one case of postoperative bleeding, one case of temporary vocal cord paralysis, two cases of delayed wound healing, two cases of paresthesia of shoulder and arm, and two cases of hypertrophic scar of the axilla. Postoperative histopathology includes 17 cases of adenomatous hyperplasia, six cases of cyst, and two cases of follicular adenoma. For all cases hospitalization period was two days. Conclusion：Thyroidectomy via axillary approach under operating microscope has a good cosmetic advantage without a post-operative scar of the anterior neck. The procedure is simple due to direct vision using operating microscope, easy to identify important structures by magnifying them, and therefore surgical time can be reduced.
