Oral venous lakes: a clinicopathologic analysis of 20 cases / 中华口腔医学杂志

<p><b>OBJECTIVE</b>To improve the recognization and treatment for oral venous lakes (OVL).</p><p><b>METHODS</b>Clinicopathologically analysis of 20 cases of oral venous lakes was performed. All the samples were removed by surgically.</p><p><b>RESULTS</b>All the lesions occurred in senile persons and located under the mucosa. Among the 20 cases, 11 were male patients and 9 were female; 18 of 20 occurred in the lower lip, another two in the upper lip and buccal mucosa. The lesions were 0.3 approximately 1.2 cm in size. Pathologically, the oral venous lake was composed of single or a few large, dilated and irregular veins. Thrombosis and organization were found within the lesions sometimes.</p><p><b>CONCLUSIONS</b>Oral venous lakes are a kind of focal anomalies of venous structure. All the 20 cases (with a follow-up time from 8 months to 4 years) has no recurrence after surgical treatment.</p>

A CLINICAL ANALYSIS OF PSEUDOPERICORONITIS OF WISDOM TOOTH OF THE MANDIBLE / 解放军医学杂志

To explore the characteristics and treatment of pseudopericoronitis of wisdom teeth of the mandible by clinical analysis of 36 cases.Results showed that the patients of pseudopericoronitis of the wisdom tooth of the mandible were of elder age,mild symptoms, totally impacted in the mandible,resulting in overgrowth of the corresponding third molar of the maxtilla overgrown.The observations indicated that the symptoms of pseudocoronitis of the wisdom tooth of the mandible was the injury inflicted to the soft tissue due to excessive growth of the third molar in the maxilla directly or indirectly.The method of treatment is to extract the overgrown third molar in the maxilla,and leave the wisdom tooth of the mandible alone.

A CLINICAL ANALYSIS OF WARTHIN TUMORS OF THE PAROTID GLAND(80 CASES REPORT) / 解放军医学杂志

cases of Warthin tumor in parotid gland were collected, the selection of operating style and personal experience in treatment were introduced. The results showed that most of the patients were senior man, the site of the tumors was all in parotid gland, the majority of the tumor was single nodule with exception of some patient who had a multiple nature. Tumor recurrence was found in patients with improper method. The results suggested that for patients who are suspected of Warthin tumor,careful physical examination and B Ultrosonic scan are necessary for both sides of parotid gland. Different operating style should be considered according to the differences of tumor site and number.

Clinical study on the micrometastasis of sentinel lymph nodes in oral squamous cell carcinoma / 解放军医学杂志

Objective To evaluate the feasibility and predictive ability of the sentinel node localization technique for patients with oral squamous cell carcinoma and determine whether the pathology of the SLN reflected the status of all the neck lymph nudes. Methods Perioperative use of a gamma probe identified radioactive SLNs. The pathology of the SLN was compared with that of the remaining neck dissection. Results Sentinel lymph node biopsy was performed on 20 cases. SLNs were found in 16 necks, among them 6 were found to be subclinical metastases. The SLN was the only lymph node containing tumor in 5 of 6. Conclusions Our preliminary investigation shows that sentinel node localization is technically feasible and predictive of cervical metastasis. SLN biopsy may aid in identifying the clinically N0 patient with occult lymph node metastasis and has the potential to decrease the number of neck dissections performed in clinically negative necks.

DETECTION OF HUMAN PAPILLOMAVIRUS DNA OF ORAL SQUAMOUS CELL CARCINOMAS BY IN SITU HYBRIDIZATION / 解放军医学杂志

By using digoxin labelled human papillomavirus(HPV) 6/11 and HPV16/18 probes,and hybridization in situ technique, the HPV DNA sequence in 50 cases of oral SCC was detected. The results showed that among them ,16 cases(32%) were positive for HPV16/18 DNA, none of the cases of OSCC was positive for HPV6/11 DNA. It was suggested that HPV16/18 in oral SCC was confirmed to be closely related with the cause of OSCC.

Studies on sentinel lymph node biopsy in clinical lymph node negative oral squamous cell carcinoma / 解放军医学杂志

Objective To evaluate the sentinel lymph node biopsy (SLNB) in clinical lymph node negative oral squamous cell carcinoma. Methods Sentinel lymph node biopsy (SLNB) by using methylene blue staining were employed to 20 patients with clinical cervical lymph node negative in oral squamous cell carcinoma. Results SLNB was successful identified in 14 of 20(70%). A 100%(6/6) accuracy of SLNB to predict cervical lymph node status was reached. Conclusion SLNB could accurately predict the cervical status of clinical negative node and decrease the extent of surgery and postoperative complication
