RESUMO
Focal cemento osseous dysplasia (FCOD) is a subgroup of benign fibro osseous lesions, which occur in a single site of tooth-bearing areas of jaws. It is usually asymptomatic and noticed accidentally through routine radiological exams. There is often no need for treatment of such lesions. This case was a 28-year-old male patient with a mixed radiolucent-radiopaque lesion in posterior part of his mandible. Based on radiographic examination, cemento ossifying fibroma (COF) was the first differential diagnosis. After the surgical removal of the lesion, histopathologic evaluation was made and the case was diagnosed as FCOD. Fortunately, after a few months of operation, there was no complication and complete bone formation was occurred.
RESUMO
INTRODUCTION: The ectopic ciliated cyst is a rare non-odontogenic cyst which occurs as a delayed complication after maxillary sinus radical surgery; this lesion emerges due to the destruction of the sinus mucosa during the surgery and entrapment of the respiratory epithelium in the region. This lesion has been observed in very rare cases following genioplasty and bimaxillary orthognathic surgery. CASE REPORT: We reported a case of the ectopic ciliated cyst in in the mandible of a 37-year-old Iranian woman following genioplasty and Lefort 1 surgery after 2 years. Its treatment was enucleation. CONCLUSION: Long-term follow-up after cosmetic surgery of both jaws is recommended due to the probability of this cyst.
RESUMO
PURPOSE: Controlled hypotension during a surgical procedure is a way to decrease blood pressure and subsequently to improve the field of operation. Clonidine is an antihypertensive agent used for induced hypotension. Correction of maxillomandibular discrepancies may necessitate performing osteotomy on both jaws in many cases. Bimaxillary orthognathic surgery is a procedure that is associated with significant blood loss. MATERIAL AND METHODS: A total of 30 participants who were candidates for double-jaw orthognathic surgery were classified into two groups with equal numbers. In one group, 300 µg oral clonidine premedication was administered 90 min before the operation, and in the other group a placebo with the same condition as in the first group. Mean arterial pressure (MAP) and heart rate at 10 min intervals, operation time, blood loss, and surgeon satisfaction were measured. RESULTS: A total of 10 men and 5 women with a mean age of 22.9 ± 2.9 years in the study group and 13 men and 2 women with a mean age of 22.1 ± 2.1 years in the control group were evaluated. The MAP was significantly lower in the clonidine group (P < 0.001). Intraoperative bleeding was 508.67 ± 46.2 mL in the placebo group and 287.33 ± 72.06 mL in the clonidine group, and the difference was statistically significant (P < 0.05). Significant differences were observed in operation time (P < 0.05) and surgeon satisfaction (P < 0.001). CONCLUSION: The authors of this study suggest clonidine premedication in bimaxillary orthognathic surgery. Hemodynamic stability, bleeding control, decrease of operative time, and enhancement of surgical results are advantages of this method.
