Clinical analysis of aneurysmal bone cyst in jaw bone / 口腔疾病防治

Objective @#To investigate aneurysmal bone cyst (ABC) in oral and maxillofacial of clinical appearance, clinical treatment and prognosis.@* Methods @#From July 2003 to December 2015, 8 patients with aneurysmal bone cyst in jaw bone was treated and recorded with the general condition, clinical symptoms, imaging examinations, surgical treatment and prognosis.@*Results @#Among the 8 patients, there were 5 females and 3 males with the age from 5 to 48 years old. 5 cases happened in mandibular bone and 3 cases originated from the maxillary bone. All the patients were primary lesions and diagnosed by pathology. CT scan showed multilocular cystic expansive space occupying lesions, septa, residual bone crest and liquid-liquid form; enhanced imaging showed the tortuous and dilated small blood vessels. Cystic wall composed of spindle shaped fiber cells, tissues and cells, broken bone like multinucleated giant cells and chronic inflammatory cells form and a ribbon like structure, cysts separated by fibrous tissue containing bone and bone fragments, hemorrhage and hemosiderin deposition was observed which was confirmed under the light microscope. The main treatment of aneurysmal bone cyst was radical operation. After 1~6 years of follow-up, no patient was found recurrence. @* Conclusion@# The imaging findings of aneurysmal bone cyst in jaw bone was distintive, with diagnosis of the disease depended on pathology; the main treatment was radical operation with good prognosis.

[Clinical study of facial artery island flap for reconstruction of oral and maxillofacial tissue defects in 96 consecutive patients].

PURPOSE: To evaluate the clinical effect of facial artery island flap for immediate reconstruction of oral and maxillofacial defects. METHODS: From March 2007 to August 2015, the clinical data of 96 patients with facial artery island flap for reconstruction of oral and maxillofacial defects were recorded and analyzed, including 46 patients undergoing anterograde facial artery flap and 50 patients undergoing reversed facial artery flap. The short-term and long-term clinical effect, including receipt site, flap survival, facial appearance and function, and postoperative complications were investigated． RESULTS: The overall success rate for facial artery island flap was 96.9%(93/96), 95.7% for anterograde flap (44/46), and 98.0% for reversed flap (49/50). All patients were followed up for six months to 6 years. The facial appearance and flap texture were satisfied. The speech and swallowing function was ideal. The scar was concealed. One patient had cervical recurrence, three had contralateral cervical lymph node metastasis. CONCLUSIONS: The facial artery island flap of submandibular area can be used to repair maxillofacial defects of medium and small sizes. The operation is simple. The reversed facial artery flap is suitable to repair upper one-third of maxillofacial defect, the survival rate is high and cosmetic outcome is ideal.

[Application of autogenous artery to repair parotid duct defect].

PURPOSE: To use autogenous artery to repair parotid duct defect, and to investigate the clinical effect. METHODS: Anesthesia epidural catheter was used to support the parotid duct and a segment of superficial temporal artery was harvested to reconstruct the defect of the parotid duct. The patients were asked to revisit 1 month, 3 months, half a year and one year postoperatively. RESULTS: No swelling and salivary fistula was noted. The parotid ducts were successfully reconstructed with good patency and normal secretion. CONCLUSIONS: Using anesthesia epidural catheter to support the parotid duct, autogenous artery is excellent for repair of parotid duct defect.
