ABSTRACT
Objective@# To explore the feasibility of curettage combined with fenestration for jaw classic ameloblastoma treatment and to provide a basis for improving the treatment of classic ameloblastoma. @*Methods@# Twenty-two patients with jaw classic ameloblastoma admitted to Liuzhou People’s Hospital from 2016 to 2019 were selected. They were treated by curettage combined with fenestration. Monthly follow-up visits were conducted after surgery, and orthopantomography was performed for reexamination to observe the recovery of bone and whether there was recurrence. @*Results @#Tumors were completely scraped off in 22 patients, no pathological fracture occurred, and no wound infection occurred after surgery. After 1 to 3 years of follow-up, 19 patients showed excellent bone recovery in the original tumor area, and no recurrence was observed. Three patients relapsed and underwent a second curettage combined with fenestration, and the bone at the original tumor site recovered well. During the 12-month follow-up, no tumor recurrence was observed. After the second curettage combined with open surgery, the bone at the original tumor site recovered well. Eight patients underwent dental implants to repair dentition defects one year after surgery.@*Conclusion@#Curettage combined with fenestration is a convenient and effective treatment for jaw classic ameloblastoma.
ABSTRACT
Objective@#The purpose of this study was to a new operative approach for sagittal condylar fractures via a preauricular small incision-based technique and to examine the effectiveness of this approach. @*Methods@#Fifteen patients (19 sides) with sagittal condylar fractures were included in the study. The incision length was approximately 4 cm through the tragus, exposing the superficial temporal vessels, which was then pulled forward. Next, the deep temporal superficial fascia was cut, and the surface of the zygomatic arch and the articular capsule of the temporomandibular joint were exposed. Joint capsule incision was performed, with mandibular condylar fracture fixation under direct vision. We followed up with the patients postoperatively for 6 months with clinical and radiographic examinations. @*Results @#All patients had 1 week postoperation before being discharged, during which 2 cases of mild facial paralysis (with lateral temporal level Ⅱ facial paralysis, with lateral temporal branch level Ⅲ facial paralysis and level Ⅱ zygomatic branch of facial nerve paralysis after treatment) were observed, after given nerve nutrition agents, 2 cases returned to normal within 3 months. No patient exhibited a postoperative delayed fistula infection or other serious complications. Intraoperative occlusion relationships recovered well, and postoperative CTs suggested that the fracture ends and condyles were in good condition. The occlusion relationship was normal for 3 months after surgery, with a degree of opening greater than 30 mm, no play in the joints and no oblique openings being observed, and reexamination 6 months after the surgery revealed no obvious scars.@*Conclusion@#This surgical method involves a small incision and clear anatomic structures and avoids damage to the facial nerve. This method provides better surgical vision for treatment of sagittal condylar fractures, is safe and convenient, and deserves clinical recommendation.
