This study was designed to provide basic data for developing exercise program that helps correcting posture by knowing the effect of strengthening and elongation exercises of upper extremity muscle to forward head posture correction. In this study determined subjects whether they had forward head posture or not. On the basis of the New York state posture rating, if a subject's posture is match up with the normal standard posture, gives 5 points and if the posture is slightly get out of the normal standard posture, gives 3 points and if the posture is apparently get out of the standard, gives 1 points. When determining the forward head posture, if talus, humerus and outer ear center are on the same line, it is determined as normal and if outer ear center is off the line less than 1.0cm, it is a slight deformation and if outer ear center is off the line more than 1.0cm, it is a high deformation. In the study selected people who have more than 1 cm gap between two vertical lines start from outer ear center and acromion separately as subjects. Length between the ideal alignment line measured by using goniometer and temporal region showed statistically significant decrease as $2.36{\pm}1.07cm$ before the intervention and $1.06{\pm}0.88cm$ after the intervention. After 4 weeks of neck and chest extensor muscle exercise, the group who exercised both showed increase in range of neck joint motion and neck flexion of the forward head posture. Meanwhile the group who only exercised neck extensor muscle only and the group who only exercised chest extensor muscle didn't showed statistically significant result. That only the group who exercised both muscles showed significant result is the different with studies before. Because this study didn't target patient who had a lesion, couldn't compare effect of the conservative manner and exercise. However, this study provides the fact that the group who exercised both neck and chest muscle had more effect than the control group.
Purpose: The aim of this study is to suggest an intervention method for clinical use in the future by analyzing the effect of breathing exercise on activity of sternocleidomastoid muscle and scalenus anterior muscle, which are respiratory synergist muscles, and pulmonary functions in patients with forward head posture. Methods: Prior to the experiment, 12 patients (experimental group) performed feedback exhalation exercise along with conventional deep neck exercise, and 11 subjects (control group) performed feedback deep neck exercise along with conventional deep neck exercise. The intervention programs were performed for 40 minutes once a day (three times a week for four weeks). Results: Before intervention, %RMS was measured for surface electromyography (sEMG), and FVC, FEV1, and FEV1/FVC were measured using a spirometer. After four weeks, these items were re-measured under the same condition and analyzed. In within-group comparison of the experimental group, activity of sternocleidomastoid muscle and scalenus anterior muscle showed a significant decrease (p<0.05)(p<0.001), and forced vital capacity (FVC) showed a significant increase (p<0.05). In within-group comparison of the control group, activity of sternocleidomastoid muscle and scalenus anterior muscle showed a significant decrease (p<0.05), and in between-group comparison, there were significant differences in activity of sternocleidomastoid muscle and FVC (p<0.05). Conclusion: Long-term forward head posture restrains exercise performance of the neck and leads to exercise avoidance of the neck during daily activities, thus restraint factors might be created even while breathing. To cut off this link, a constant effort is required and diversified research on the correlation between neck functions and breathing should be conducted.
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.

Supracricoid partial laryngectomy (SCPL) with cricohyoidoepiglottopexy (CHEP) or cricohyoidopexy (CHP) involves the removal of the whole thyroid cartilage, both true and false vocal cords, the ventricles, and the paraglottic spaces, sparing the cricoid cartilage, hyoid bone, and at least one functional and mobile cricoarytenoid unit. Reconstruction is performed by suturing of the cricoid cartilage up tightly to the hyoid bone, so trachea-releasing procedures are needed to prevent leakage at anastomosis site. In case of advanced tranglottic cancer invading tracheal tracheal wall, we need to perform additional circumferentrial circumferential tracheal wall resection. However, when we perform SCPL, circumferential resection of tracheal wall is limited because SCPL procedure itself needs releasing of tracheal length. We report a case of advanced transglottic cancer involving tracheal wall treated with induction chemotherapy and SCPL including tracheal wall resection with reconstruction of tracheal defect by sternocleidomastoid muscle flap covered with skin graft.

Purpose : In this study, we compared the effects of ankle, McKenzie, and cervical stabilization exercises in individuals with a forward head posture. Outcome measures investigated included the neck disability index, craniovertebral angle (CVA), cranial rotation angle (CRA), and thickness of the longus colli muscle (LC) and carotid artery (CA) post-intervention. Methods : The study included 20 individuals with a forward head posture, who were assigned to an experimental group (EG, individuals performed ankle exercises) or control group (CG, individuals performed McKenzie and cervical stabilization exercises). The EG intervention was specifically designed to enhance proprioception in the ankle joint and strengthen the ankle muscles to improve overall stability and function. In contrast, CG interventions aimed to improve neck muscle balance and cervical spine alignment. Paired t-tests were used to analyze intragroup changes and independent t-tests to determine intergroup differences pre-and post-intervention. The significance level for all statistical tests was set at α=.05. Results : We observed significant post-intervention improvements in both groups, specifically, in the CVA, CRA, and LC and CA thickness (p<.05). These results indicate that ankle, McKenzie, and cervical stabilization exercises were useful for neck posture correction, improved muscle balance, and enhanced blood flow to the neck. Conclusion : This study underscores the positive effects of ankle, McKenzie, and cervical stabilization exercises in individuals with a forward head posture. Our study highlights the benefits of these exercises for posture correction and overall neck health and the clinical effectiveness and usefulness of ankle exercises as an important intervention to improve forward head posture.

Purpose : Forward head posture (FHP), characterized by the anterior positioning of the head relative to the spine, is a common postural deviation that can lead to neck pain, reduced mobility, and muscle imbalances. Recently, high-frequency deep heat therapy (HFDT) has been gaining attention for the intervention of FHP. This research aims to investigate the efficacy of HFDT in comparison to instrument assisted soft-tissue mobilization (IASTM) for treating FHP among 30 young adults. Methods : Participants were randomly assigned to either the HFDT or IASTM group. The study focused on examining changes in neck joint mobility, pain thresholds, rounded shoulder distance, lower trapezius muscle strength, and neck dysfunction. Measurements were taken before and after the interventions. Paired t-tests were used for within-group analyses, and independent t-tests were employed for between-group comparisons. The statistical significance level α was set to .05. Results : Statistically significant improvements were observed across all measured parameters in both groups (p<.05). The HFDT group showed significantly greater enhancements in neck joint mobility, pain thresholds, rounded shoulder distance, lower trapezius muscle strength, and neck dysfunction parameters. Specifically, HFDT was more effective than IASTM in improving neck joint mobility, right upper trapezius pain threshold, left rounded shoulder distance, and right lower trapezius strength. The only exceptions were neck flexion range of motion, left upper trapezius pain threshold, right rounded shoulder distance, and left lower trapezius strength, where no significant differences were found between the groups. Conclusion : The findings suggest that HFDT, by combining the benefits of high-frequency therapy and manual therapy, effectively alleviates upper trapezius muscle pain and tension, enhances neck mobility, and strengthens lower trapezius muscles. Thus, HFDT could be considered a valuable intervention for clinicians aiming to address FHP and associated musculoskeletal problems.

PURPOSE: The purpose of this study was to investigate that the differences in sternocleidomastoid muscle activity, neck rotation angle, neck lateral bending angle and neck lateral bending onset time between conditions with and without visual biofeedback during neck rotation. METHODS: Ten male and four female adults with condition of forward head posture were recruited in this study. Subjects conducted to left and right maximal neck rotation under the conditions with and without visual biofeedback. During neck rotation, kinematic data of neck rotation, neck lateral bending movement, and electromyography activities of bilateral sternocleidomastold muscles were collected. Differences in dependent variables between conditions with and without visual biofeedback were analyzed using paired t-test. RESULTS: There were significant decreases in lateral bending angle, while lateral bending movement onset time was delayed significantly when applying visual biofeedback (p<.05). However, there were no significant differences in the activation of left and right sternocleidomastoid muscles and neck rotation angle between conditions with and without visual biofeedback (p>.05). CONCLUSION: These findings suggest that visual biofeedback may be effective for axial rotation of cervical spine during neck rotation in adults with forward head posture.
Objective: The purpose of this study was to investigate the effect of a lower trapezius strengthening exercise program on an unstable support surface on pain, neck dysfunction, psychosocial factors, and postural alignment in neck pain patients with forward head posture. Design: A randomized controlled trial Methods: A total of 36 neck pain patients participated in this study. Screening tests were performed and assigned to experimental group (n=18) and control group (n=18) using randomization program. Both groups performed the lower trapezius strengthening exercise program. In addition, in the experimental group, an exercise program for lower trapezius muscle strengthening was performed on an unstable support surface. All interventions were performed 3 times a week, for a total of 5 weeks. quadruple visual analogue scale (QVAS), neck disability index (NDI), short form (SF)-12, and postural alignment were measured before and after the intervention to compare their effectiveness. Results: Both groups showed significant differences in QVAS, NDI, SF-12, and postural alignment before and after intervention (p<0.05). In addition, the experimental group showed significant differences in NDI and postural alignment compared to the control group (p<0.05). Conclusions: The lower trapezius strengthening exercise program on unstable support surfaces is an effective intervention method with clinical significance in improving neck disability and postural alignment in patients with neck pain with forward head posture.
This study aimed to investigate the association of the muscle activity around the neck of the operator(dental hygienists') according to the change in the patient's neck angle during a direct visual inspection on the maxillary right-side molar palatal surface. The operators were $4^{th}$ year dental hygiene students, who are future dentalhy gienists, having accurate understanding on and awareness of the location of the operation site, hand fixation, and how to use the tools. Data on the change in the muscle activity around the neck were collected by using surface electromyography and neck goniometer. SPSS statistics 20 was used for statistical analyses including Shapiro-wilk test and one-way ANOVA. As a result, the activities of the operator upper trapezius, cervical erector spinae, and levator scapulae muscles significantly decreased when the patient's head was angled compared to when it was not. For the angle of the operator head, the head bend significantly decreased when the patient's head was angled than when it was not. Based on the study results, it is expected that angling the patient's head when treating his or her teeth will decrease the excessive muscle activity around the neck of the operator, and will reduce muscle fatigue. Therefore, angling the head of the patient while treating his or her teeth is recommended. This suggests that muscle pain caused by repetitive actions in the wrong posture can be reduced.

A Killian-Jamieson diverticulum (KJD) is an unfamillar and unusual cervical esophageal diverticulum. This diverticulum originates on the anterolateral aspect of the esophagus through the Killian-Jamieson's area that is formed between cricopharyngeal muscle and the lateral to longitudinal esophageal muscle. Recently, we experienced a patient who was found outpouching lesion on lateral side of left esophagus on the duodenoscopy. Then, a barium esophagography performed and in left lateral position demonstrated a left-sided diverticulum with a frontal projection, highly suggestive of a KJD. There are two ways of surgical approach to manage the KJD. First is external approach, another one is endoscopic approach. In common, external approach has been recommended for the treatment of KJD because of concern of nerve injury. We present a case of KJD that underwent external approach and sternocleidomastoid muscle flap in the management of KJD.
