ABSTRACT
Objective:To evaluate the feasibility of fine-needle aspiration cytology (FNAC) in diagnosing vascular abnormality in oral and maxillofacial region.Methods: The method of retrospective study was used.The data from the patients who underwent FNAC from 2011 to 2014 in Department of Oral and Maxillofacial Surgery, Peking University School of Stomatology were collected.All the included patients were divided into surgery group and non-surgery group.The patients in surgery group underwent lesion resection and the postoperative pathological results were gained.The patients in non-surgery group underwent periodical sclerotherapy.The accuracy of FNAC was identified by histopathologic diagnosis in surgery group and the effect of sclerotherapy in non-surgery group.Results: In this study, 93 patients were involved, including 51 males and 42 females.The median age was 2.5 years.Among them, 67 cases were judged as vascular abnormality by FNAC, and 63 cases were in consistent with final diagnosis and 4 cases were not.Among the other 26 cases which were diagnosed as other diseases by FNAC, 5 cases were accorded with final diagnosis.Therefore, the sensitivity of FNAC on diagnosis of vascular abnormity was 93% and its specificity was 84%.Among them, there were 29 cases in the surgery group and 64 cases in the non-surgery group.FNAC results were in consistent with the postoperative pathological results in 20 cases in surgery group (69%), and not consistent with pathological results in 9 cases.The pathological diagnoses included vascular malformations (3 cases), neurofibromas (2 cases), hamartoma (1 case), sebaceous cyst (1 case), adenolymphoma (1 case), and descriptive diagnosis (1 case).In non-surgery group, FNAC results were in consistent with the clinical effect of sclerotherapy in 61 cases (95%).There were 3 misdiagnosed cases.The coincident rate between the result of FNAC and that of pathological or clinical diagnosis was 86%.Conclusion: FNAC is a feasible and minimal invasive method to diagnose vascular abnormality in oral and maxillofacial region.
ABSTRACT
Vascular birthmarks are the most common disease.The morbidity is about 2.5%,most of the lesions occur in oral and maxillofacial regions which accounts for 40%-60% of the total lesions.In 1982,Mulliken and Glowacki proposed a biologic classification of vascular birthmarks on the basis of their clinical manifestations,histopathological features,and natural history.They defined hemangiomas as vascular tumors with a growth phase,marked by endothelial proliferation and hypercellularity,and an involutional phase.They recognized that many entities referred to as hemangiomas are actually structural malformations of the vasculature,derived from capillaries,veins,lymph vessels,or arteries or from a combination of these sources.The classification was confirmed and issued by International Society for the study of vascular anomality(ISSVA) in 1988.Waner and Suen amended the above category in 1995.This paper presents the new classification of vascular birthmarks and the developments in this field in re-cent years,including the pathology,clinical features and the therapy.For example,the classification of venular malformation categorized by Waner in 1989;the classification of lymphous malformation by Waner and Suen in 1995;and the treatments according to above classifications.
ABSTRACT
Objective: To compare the expression of multidrug resistant gene( mdr 1 ) in oral squamous cell carcinoma (SCC) before and after chemotherapy. Methods: Mdr 1 gene expression in 21 cases of oral SCC was detected before and after chemotherapy by dot blot hybridization, Results: Before and after sigle drug chemotherapy mdr1 mRNA(?10 5 copies/?g) in SCC tissue was 1.98?1.72 and 3.74?3.24( P
ABSTRACT
Objective: To study the effective treatment methods of arteriovenous malformation(AVM) in jaw bone through retrospective review. Methods:33 patients with jaw AVM were analyzed by history, treatment methods and outcome. Results: Among the 33 patients 6 were treated by embolization only, 12 by curretting, 10 by resection of the bone lesions. The cure rate in the three groups was 2/6,11/12 and 10/10 respectively. Conclusions: Embolization combined with curretting may be the effective methods to treat facial bone AVM without resection of bone.
ABSTRACT
This paper reports the sensitizing effect of Hematoporphyrin Derivative (HPD) to Radiotherapy (RT) and long survival rates of 28 patients were treated by HPD 5mg/kg iv+D T31Gy/10f/12d+Surgery with squamous cell carcinoma in head and neck. The result was compared with 33 patients who received routine preoperative radiotherapy D T40Gy/20f/26d without HPD.The total HPD group were 44.4%(13/28) of this patients failed to evidence of living tumour cell within surgical specimens. 59.09%(13/22) of patients with the tumour diameter of 4cm in HPD group. The control group was 9.1% only (P
