Purpose: This study examined the correlations between a forward head posture and the endurance and maximal voluntary contraction of the deep neck flexor, neck pain, and the changed position of the mandible. Methods: The subjects of this study were 50 male and female adults who work at a desk for at least four hours a day. The head-spine angle was photographed with a camera, and the endurance and maximal voluntary contraction of the deep neck flexor and the changed position of the mandible were measured using pressure biofeedback. The Neck Disability Index was used to measure neck pain. To examine the correlations between a forward head posture and the endurance and maximal voluntary contraction of the deep neck flexor as well as the changed position of the mandible, a Spearman's correlation analysis was conducted. The statistical significance was set at 0.05. Results: A forward head posture and the endurance of the deep neck flexor showed a statistically significant positive correlation, and a forward head posture and neck pain showed a statistically significant negative correlation. In addition, the endurance of the deep neck flexor and neck pain showed a statistically significant negative correlation. Conclusion: The results of this study show that a forward head posture and the endurance of the deep neck flexor were correlated; in addition, a forward head posture and neck pain were correlated. Therefore, enhancing the endurance of the deep neck flexor can assist in correcting an imbalanced forward head posture, which can reduce neck pain.

Neurilemmomas are benign nerve sheath tumors arising from peripheral Schwann cells. The tumor composed of Schwann cells and collagen fibers, can occur in any region of the body where there is a nerve that has a Schwann sheath. The incidence of the tumor in the head and neck is about 30% with many of these occurring on the vagus nerve. Neurilemmoma is characterized by solitary occurrence, with sharp demarcation and encapsulation. Multiple genesis is very rare. This article presents a rare case of multiple neurilemmomas located bilaterally in the cervical region.

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.

Sinonasal malignant tumors comprise less than 1% of all cancers and 3% of all malignant tumors of the head and neck, which explains a lack of large series addressing the clinical characteristics and management of these tumors. Neck node metastasis occurs in only about 7% to 15% of malignant tumors compared with other head and neck cancers. A 90-yr-old woman presented with left palpable neck mass and right nasal mass occupying nasal cavity. Fine needle aspiration biopsy of left neck mass results in metastatic squamous cell carcinoma(SCC). PET/CT shows intense FDG uptake in right nasal cavity with bone invasion. Histopathologic examination of excised lesion in the right nasal cavity revealed SCC. We report here on a primary sinonasal SCC with contralateral lymph node metastasis.

Neck mass is a common manifestation from head and neck malignancy, most of which come from mucosal squamous cell carcinomas in the upper aero-digestive tract. However, once aspiration cytology suggests atypical malignant cells in the neck mass rather than metastatic squamous cell carcinomas, it is confusing to decide the adequate diagnostic work-ups and treatment planning. Here, we report a 29-year-old woman presenting with a growing neck mass mimicking malignancy of unknown origin, which was finally diagnosed as primary lymphoepithelial carcinoma in the parotid gland with multiple metastases to the lymph nodes. The patient underwent comprehensive neck dissection and total parotidectomy and the adjuvant radiation treatment was given. Our report highlight that the primary salivary gland cancer should be considered as the potential tumor origin in case of malignancy of unknown origin in the head and neck region and neck mass suggestive of atypical carcinomas.

Head and neck abscess usually requires hospitalization, intravenous antibiotic therapy, and surgical incision and drainage. Open surgical drainage may result in unsightly scars. We report two cases of a 56-year-old man with a facial abscess and a 47-year-old man with a parotid abscess. The patients were successfully treated with ultrasound-guided angiocatheter irrigation and drainage without scar. Ultrasound-guided angiocatheter irrigation and drainage can be a simple, safe and effective alternative procedure to open surgery in the management of the selected head and neck abscesses.

Background and Objectives: Supraglottic cancer have a great tendency to spread cervical lymph nodes and lymph node metastasis is a well known prognostic factor. However the treatment for N0 neck in supraglottic cancer is still controversial. Materials and Methods: We retrospectively analyzed our neck management of supraglottic cancer patients who present with cN0 contralateral neck from 1989 through 1997. 36 patients were eligible for analysis. The primary site was surgically removed and the neck was managed by elective neck irradiation (ENI), elective neck dissection (END), or therapeutic neck dissection (TND) with postoperative radiation therapy (PORT). Results: Our results revealed that 18 of 36 patients have clinically negative neck, another 18 patients have clinically positive neck (N1-3). In clinically negative group, 12 of 18 patients were received ENI and there was 1 failure in contralateral neck area. Remaining 6 patients were received END with PORT and there was no failure. In clinically positive neck group, 3 of 18 patients were received ipsilateral TND and an additional contralateral END with PORT. Remaining 15 patients who were received TND with PORT, developed 3 neck failure. Conclusion: ENI or ipsilateral or bilateral END can be done in the cN0 neck of supraglottic cancer however ipsilateral TND and contralateral END with PORT is reasonable for the cN(+) neck.

Knowledge of variations of veins of head and neck in relation to internal jugular, external jugular, anterior jugular and facial veins is important to surgeons doing head and neck surgery as well as to radiologists doing catheterization and to clinicians in general. In the current case, congenital atresia of the left internal jugular vein is reported. During neck dissection, superficial veins of neck and left external jugular vein was engorged and the left internal jugular vein was look like a fibrotic band. The left common carotid artery and vagus nerve was normal.
