At present, there are four surgical treatments, namely, dissection of carotid artery tumor, resection of carotid artery, revascularization after carotid resection, endoarterial implantation of covered stent combined with surgical resection. However, there is currently no consensus on the standard surgical approach to choose. This paper describes the four surgical methods, which are expected to be helpful for head and neck surgeons to choose the surgical methods for head and neck tumors involving the carotid artery.展开更多

This paper mainly introduced the epidemiology, diagnosis, treatment and prognosis of head and neck tumors, especially the malignancies in China. It emphasized that to assign protocols on a case-by-case basis (custom made) and the combined therapy are key points to improve the cure rate or survival rate for head and neck malighancies. Up to now, the 5-year survival rate for squamous cell carcinoma of head and neck was about 62% (1986), and about 71% (1987) for carcinoma of salivary gland origin.展开更多

It accounted for 39. 5% of all the tumors blopsied in the same interval. In this series, 72. 4% was malignant which accounted for 45. 77% of malignant tumors in different parts of the whole body. For benign tumors in the head and neck, the ratio of male to female was 0. 84:1, and for malignant tumors In the head and neck it was 2. 4:1. The most frequently involved site by the malignant tumors were :nasopharynx, mouth, maxillofacial regions, and neck. THe majority (62. 65%) of malignant tumors were located in the nasopharynx which accounted for 28. 68% of all malignanties of which the ratio of mate and female was 3:1, peak age was 41-50 years, 18 of themwas under 10 years of age, the youngest was 1 1/2 years andthe oldest was 84 years old. These data showed that malignant tunors in the head and neck regions, expecially those in the nasopharynx, are common in Guanxi province, China. The program for cancer research on prevention and treatment should be enforced.展开更多

Therefore, therapeutic planning should always extend beyond the resection to include functional and aesthetic reconstruction, preferably immediately. Microsurgical reconstruction represents a significant advance, but has not yet been perfected. Rapid prototyping (RP) comes as a new technology for the purpose of assisting the surgeon in the visual and tactile aspects of surgery, providing diagnostic accuracy and increasing the success of surgical planning. The authors demonstrate the technological advances in the manufacture of customized mandibular prostheses with the assistance of RP and practical applications of these methods.展开更多

The incidence of PCAC in the neck is relatively low. The age of onset in PCAC ranges from 5 to 70 years old. Clinically, PCAC typically shows up as painless nodules or lumps. In immunohistochemistry, positive expression of CK-7, GCDFP-15, AR, and myoepithelial markers are helpful in the diagnosis of PCAC. This case report pertains to a 59-year-old male of Asian descent. Five years ago, a painless mass was discovered behind his right ear, which grew slowly. This patient was identified as PCAC based on clinical symptoms, pathology, immunohistochemistry, and imaging characteristics. PCAC involved the parotid gland in this case;it is easy to be misdiagnosed as a primary malignant tumor of the parotid gland on imaging. Furthermore, a thorough set of clinical, imaging, pathological, and immunohistochemical examinations must be performed to make a diagnosis because it is challenging to differentiate PCAC from metastatic breast carcinoma. Conclusion: A well-developed multidisciplinary examination is essential because PCAC can be challenging to diagnose and differentiate.展开更多

All the diagnosis were confirmed by pathologic examination. There were 5485 cases (69.62%) of malignant tumors. Nearly an half of malignant tumors were in the nasopharynx (49.32%). Among the malignant tumors of the nasopharynx, 2698 were carcinoma (99.34%) and only 18 (0.66%) sarcoma. Nine of them were under 10 years of age, the youngest patient was 3 years old, and this is rare in our county. The incidence of head and neck tumors was 37.66% and that of the head and neck malignancies was 26.22% of tumors in the whole body. This study indicates that incidence of malignant tumor in head and neck was rather higher, it is worth to improve ths procedure of treatment and prevention.展开更多

Methods: We searched PubMed, MEDLINE, BioMed, and EMbase databases for studies that assessed the association between clinicopathological and prognostic significance and CTCs in patients with head and neck cancer. Studies obtained from search strategy were screened using pre-specified criteria, and necessary data were retrieved for meta-analysis. Results: Seventeen studies with 816 patients were eligible for combined analysis. Presence of CTCs in peripheral blood was significantly associated with N stage (OR 0.50, 95%CI [0.30, 0.81], n = 10, P = 0.005). Patients in the high-CTC group were significantly associated with poorer disease-free survival (DFS;HR = 1.73, 95%CI [1.01 - 2.96], P = 0.050) and poorer overall survival (OS;HR = 2.53, 95%CI [1.37 - 4.69] P = 0.003). Further analyses indicated strong prognostic powers of CTCs in non-RT-PCR group and pre-treatment group. Conclusion: Our meta-analysis indicates that presence of CTCs is associated with higher N stage and poorer prognosis in patients with head and neck cancer. The potential for further clinical application may be needed for further investigation.Purpose: The aim of the study was to evaluate the association between clinicopathological and prognostic significance and circulating tumor cells (CTCs) in patients with head and neck cancer.

However, masticatory rhythm is crucial for masticatory performance and nutritional intake. This study aimed to explore the impact of using a maxillofacial prosthesis to restore masticatory rhythm in mandibulectomy patients with a novel wearable device. Methods: Twelve patients who underwent mandibulectomy and were rehabilitated with maxillofacial prosthesis were recruited. Chewing rate, cycle durations, coefficient of variation of cycle durations (CV), changing times of skin morphology on the back of the ear pinna area (SM), and masticatory performance were measured during gum chewing without and with a denture using a wearable jaw movement rhythm tracking device. A paired t-test and the Pearson correlation coefficient were used for statistical analysis. Results: The chewing rate increased by 8.6 cycles/min with dentures (P P = 0.01). The CV and SM decreased with dentures (P = 0.004 and P = 0.01, respectively). Significant correlations were found between the CV and SM without dentures (P = 0.004). Conclusion: 1. Wearing maxillofacial prostheses can improve masticatory rhythm in patients who undergo mandibulectomy with Eichner B2 occlusal supports. 2. The wearable device is available for measuring masticatory rhythm in patients with jaw defects in clinics. 3. Changing times of the skin morphology on the back of the ear pinna indicate jaw movement stability through a simpler process than the coefficient of variation of cycle durations.展开更多
